The present invention relates to a composition comprising a combination of modified starch, Ci 3 -Ci 5 fatty acid and clay, as well as a use of the composition.

BACKGROUND ART

The use of mineral clays as medicinal and cosmetic tools has been popular for a long time.

Clays are used to absorb excess oil, dirt, and toxins from the skin while simultaneously exfoliating and improving skin circulation. Some clays, such as bentonite clay, are primarily ingested for medicinal purposes such as detoxification or mineral deficiencies.

Other clays, such as French Green clay and Rhassoul clay, are used externally for skin conditions and for cosmetic purposes. Clays come in a variety of colors such as red, green, white, gray, and can range in texture from coarse and heavy to fine and fluffy. The different colors of clays occur because of their natural mineral content.

In modem cosmetics, such clays are used as key active ingredients for oil control products which are sold in the form of oil control face washes, etc. In some rinse off cosmetic compositions, clays are included.

DISCLOSURE OF INVENTION

A rinse off cosmetic composition including clay may leave a deposition of the clay on a keratin substance such as skin even after the composition is rinsed off from the keratin substance. The remaining deposition of clays, if present, can contribute to oil control.

On the other hand, a composition including clay may not be stable such that it may cause a phase separation.

An objective of the present invention is to provide a stable composition which can be rinsed off from a keratin substance such as skin and can leave an enhanced deposition of clay on the keratin substance after rinsing off the composition from the keratin substance.

The above objective can be achieved by a composition, comprising:

(a) at least one modified starch;

(b) at least one C 13 -C 15 acid; and

(c) at least one clay.

The (a) modified starch may be hydrophobic.

The (a) modified starch may be hydroxyalkyl-modified starch, preferably selected from the group consisting of hydroxyethyl starch, hydroxypropyl starch, hydroxyethyl starch phosphate, hydroxypropyl starch phosphate, and a mixture thereof.

The (b) Ci3-Ci5 fatty acid may be myristic acid

The (c) clay may be kaolin.

The weight ratio of the amount of the (b) C13-C15 fatty acid/the amount of the (a) modified starch may be 1.1 or more, preferably 1.2 or more, and more preferably 1.3 or more.

The (a) modified starch and the (b) C13-C15 fatty acid may form a complex.

The (c) clay may be coated with the (a) modified starch and the (b) C13-C15 fatty acid, preferably a complex formed by the (a) modified starch and the (b) C13-C15 fatty acid, and more preferably a complex formed by hydrophobic modified starch and myristic acid.

The amount of the (a) modified starch in the composition may be from 0.01% to 15% by weight, preferably from 0.1% to 10% by weight, and more preferably from 0.5% to 5% by weight, relative to the total weight of the composition.

The amount of the (b) C13-C15 fatty acid may be from 1% to 20% by weight, preferably from 3% to 15% by weight, and more preferably from 5% to 10% by weight, relative to the total weight of the composition.

The amount of the (c) clay may be from 1% to 40% by weight, preferably from 5% to 35% by weight, and more preferably from 10% to 30% by weight, relative to the total weight of the composition.

The composition according to the present invention may further include (d) water.

The amount of the (d) water may be from 1% to 50% by weight, preferably from 5% to 40% by weight, and more preferably from 10% to 30% by weight, relative to the total weight of the composition.

The composition according to the present invention may be a cosmetic composition, preferably a rinse-off composition, and more preferably a rinse-off cleansing composition.

The present invention also relates to a cosmetic process for a keratin substance, such as skin, comprising the step of:

applying the composition according to any one of Claims 1 to 12 onto the keratin substance.

The present invention also relates to a use of a combination of:

(a) at least one modified starch; and

(b) at least one C 13 -C 15 fatty acid

in order to increase the deposition on a keratin substance such as skin of (c) at least one clay.

The (a) at least one modified starch and the (b) at least one C13-C15 fatty acid may form a complex, and preferably the (c) at least one clay is coated with the complex.

BEST MODE FOR CARRYING OUT THE INVENTION

After diligent research, the inventors have discovered that it is possible to provide a stable composition which can be rinsed off from a keratin substance such as skin and can leave an enhanced deposition of clay on the keratin substance after rinsing off the composition from the keratin substance .

The composition according to the present invention comprises a combination of (a) at least one modified starch, (b) at least one C 13 -C 15 fatty acid, and (c) at least one clay.

The composition according to the present invention is stable such that it does not cause a phase separation for a long period of time.

The composition according to the present invention can be rinsed off from a keratin substance such as skin and can leave an increased amount of a deposition of clay on the keratin substance after rinsing off the composition from the keratin substance.

A deposition of clay can contribute to oil control. Since the composition according to the present invention can increase the amount of the deposition of clay on a keratin substance such as skin, the composition according to the present invention can provide long-lasting oil control effects. Thus, for example, the composition according to the present invention can control or suppress for a long period of time non-preferable events such as greasy appearance caused by oily substances such as sebum on a keratin substance such as skin. Also, the increased amount of the deposition of clay on a keratin substance such as skin can provide a smooth feeling to touch for a long period of time.

The (c) clay may be coated with the (a) modified starch and the (b) C 13 -C 15 fatty acid. The (a) modified starch and the (b) C 13 -C 15 fatty acid may form a complex. Thus, the (c) clay may be coated with a complex formed by the (a) modified starch and the (b) C 13 -C 15 fatty acid. It is preferable that the complex be formed by hydrophobic modified starch and myristic acid.

The hydrophobicity of the (c) clay can be enhanced by the (a) modified starch and the (b) C 13 -Ci 5 fatty acid, preferably a complex formed by the (a) modified starch and the (b) C 13 - C 15 fatty acid, and more preferably a complex formed by modified hydrophobic starch and myristic acid. Therefore, the (c) clay can deposit more on a keratin substance such as skin, due to hydrophobic-hydrophobic interaction between the (c) clay and the keratin substance. This can result in the increase in the amount of the deposition of the (c) clay on the keratin substance.

Hereafter, the present invention will be described in a detailed manner.

[Composition]

One of the aspects of the present invention is a composition, comprising:

(a) at least one modified starch;

(b) at least one C 13 -C 15 fatty acid; and

(c) at least one clay.

In one embodiment of the present invention,

the amount of the (a) modified starch in the composition is from 0.01% to 15% by weight, preferably from 0.1% to 10% by weight, and more preferably from 0.5% to 5% by weight, relative to the total weight of the composition,

the amount of the (b) C13-C15 fatty acid is from 1% to 20% by weight, preferably from 3% to 15% by weight, and more preferably from 5% to 10% by weight, relative to the total weight of the composition, and

the amount of the (c) clay is from 1% to 40% by weight, preferably from 5% to 35% by weight, and more preferably from 10% to 30% by weight, relative to the total weight of the composition.

(Modified Starch)

The composition according to the present invention includes (a) at least one modified starch. A single type of modified starch may be used, or two or more different types of modified starches may be used in combination.

The (a) modified starch may be in the form of a powder. In other words, the (a) modified starch may be in the form of particles. In this case, the particle size of the (a) modified starch is not limited.

It is preferable that the (a) modified starch is film-forming, ie, is capable of forming a film.

The (a) modified starch is based on a base starch. Base starch, as used herein, is intended to include all starches derived from any native source, any of which may be suitable for use herein. A native starch, as used herein, is one as it is found in nature. Also suitable are starches derived from a plant obtained by standard breeding techniques including

crossbreeding, translocation, inversion, transformation or any other method of gene or chromosome engineering to include variations thereof. In addition, starches derived from a plant grown from artificial mutations and variations of the above generic starches, which may be produced by known standard methods of mutation breeding, are also suitable herein.

Typical sources for the starches are cereals, tubers, roots, vegetables and fruits. The native source can be waxy varieties of corn (maize), pea, potato, sweet potato, banana, barley, wheat, rice, oat, sago, amaranth, tapioca (cassava), arrowroot, canna, and sorghum, as well as low and high amylose varieties thereof. As used herein, the term "low amylose" starch is intended to include a starch containing no more than about 10%, particularly no more than 5%, and more particularly no more than 2% amylose by weight. As used herein, the term "high amylose" starch is intended to include a starch containing at least about 50%, particularly at least about 70%, and more particularly at least about 80% amylose by weight. High amylose starches may be preferable.

The (a) modified starch may be pre-gelatinized. Pre-gelatinization and techniques for achieving pre-gelatinization are known in the art and disclosed for example in US Pat. Nos. 4,465,702, 5,037,929, 5,131,953, and 5,149,799. Also see, Chapter XXII-"Production and Use of Pregelatinized Starch", Starch: Chemistry and Technology, Vol. Ill-Industrial Aspects, RL Whistler and EF Paschall, Editors, Academic Press, New York 1967. The term pregelatinized is intended to mean swollen starch particles, which have lost their birefringence and/or maltese crosses in polarized light. Such pre-gelatinized starch derivatives are substantially soluble in cold water without cooking. In this context "soluble" does not

necessarily mean the formation of a true molecular solution, but may also mean a colloidal dispersion. In one embodiment, the starch is completely pre-gelatinized.

The pre-gelatinized modified starch is easily and quickly soluble even in cold water.

Pre-gelatinization may be achieved by methods which include, without limitation, drum drying, extrusion and spray drying. In one embodiment, extrusion is used for the

simultaneous cooking and drying of the starch (see for example US Pat. No. 3,137,592).

This process makes use of the physical processing of a starch/water mixture at elevated temperatures and pressures which brings about the gelatinization of the starch, followed by expansion after leaving the nozzle with sudden evaporation of the water.

In one embodiment, pre-gelatinization is completed to provide good solubility and eliminate undissolved particles, which may give rise to an unpleasant, sandy feel in the composition.

In one embodiment, the starch has a majority of intact starch granules. Aqueous dispersions of pre-gelatinized starch derivatives having a largely intact granular structure typically have a more uniform smooth texture than aqueous dispersions of starches without a granular structure, which may have a slightly gritty feel. In the case of pre-gelatinized starches with an intact granular structure, the native internal structure of the hydrogen bonds is destroyed, but the external shape or form is maintained.

The (a) modified starch may be crosslinked. Crosslinking of the starch chains can be achieved by suitable crosslinking agents, that is, bifunctional compounds. In one embodiment, the crosslinking method used is phosphorylation, in which the starch is reacted with phosphorous oxychloride, phosphorous pentoxide, and/or sodium trimetaphosphate. Two starch chains are crosslinked by an anionic P-0 group. The anionic character of the crosslinking sites assists the emulsion-stabilizing action of the starch to be used according to the present invention. In another embodiment, the crosslinking method is by means of C4-C18 alkane or alkene dicarboxylic acids which include without limitation C4-C8 alkane

dicarboxylic acids, exemplified by adipic acid. The alkane or alkene dicarboxylic acid links two starch chains via ester bonds. It can be in straight or branched chain form. The derivatives may be obtained, for example, by reacting starch with the mixed anhydrides of dicarboxylic acid and acetic acid. In one embodiment, less than 0.1 weight percent based on the dry starch crosslinking agent is used. In another embodiment, about 0.06 to 0.1 weight percent based on the dry starch crosslinking agent is used.

It is preferable that the (a) modified starch be hydrophobic. It is more preferable that the surface of the (a) modified starch be hydrophobic.

The modification to make starch hydrophobic may be performed by grafting hydrophobic functional groups such as Ci- 6 acyl (acetyl), C1-6 hydroxyalkyl (hydroxyethyl or

hydroxypropyl), carboxymethyl or octenylsuccinic group.

The alkyl moiety of the functional group may have 1 to 6 carbon atoms, preferably 2 to 5 carbon atoms, and more preferably 3 or 4 carbon atoms.

It is preferable that the (a) modified starch be hydroxylalkyl-modified starch.

The position of the hydroxyl group, which is bound to the starch backbone via an alkyl group such as 2 to 6 carbon atoms in the alkyl group, is not critical and can be in the alpha to omega position. In one suitable embodiment, the degree of substitution of the hydroxyalkylation is about 0.08 to 0.3. The degree of substitution is the average number of substituted OH groups of the starch molecule per anhydroglucose unit. The hydroxyalkylation of a starch can be brought about by reacting a native starch with alkyl ene oxides with the appropriate number of carbon atoms, including without limitation hydroxypropylation by reaction of the starch with propylene oxide. The hydroxyalkyl-modified starch can also contain more than one hydroxyl group per alkyl group.

The hydroxyalkyl-modified starch may be selected from the group consisting of hydroxy ethyl starch, hydroxypropyl starch, hydroxyethyl starch phosphate, hydroxypropyl starch phosphate, and a mixture thereof.

The processes for preparing the hydroxyalkyl-modified starch may be conducted in any order. However, one skilled in the art would understand the advantages of certain orders. For example, hydroxypropylation would typically be conducted before crosslinking, if the starch is crosslinked, with phosphorous oxychloride as the typical hydroxypropylation process would destroy some of the crosslinking achieved.

Examples of the hydroxyalkyl-modified starch preferably used in the present invention may include the following:

Hydroxypropyl starch phosphate (pre-gelatinized, com starch) marketed by Akzo Nobel as Structure ZEA and XL; and

Com starch modified (hydroxypropylated, pre-gelatinized, high amylose) marketed by Akzo Nobel, as AMAZE.

The amount of the (a) modified starch in the composition according to the present invention may be 0.01% by weight or more, preferably 0.1% by weight or more, more preferably 0.5% by weight or more, and even more preferably 1 % by weight or more, relative to the total weight of the composition.

On the other hand, the amount of the (a) modified starch in the composition according to the present invention may be 15% by weight or less, preferably 10% by weight or less, more preferably 5% by weight or less, and even more preferably 3% by weight or less, relative to the total weight of the composition.

(Ci3-Ci5 Fatty Acid)

The composition according to the present invention includes (b) at least one C13-C15 fatty acid. A single type of C13-C15 fatty acid, or two or more different types of C13-C15 fatty acids may be used in combination.

It is preferable that the (b) C13-C15 fatty acid is saturated. The saturated C13-C15 fatty acid can be selected from the group consisting of tridecylic acid (tridecanoic acid), myristic acid (tetradecanoic acid) and pentadecylic acid (pentadecanoic acid).

It is possible that the (b) C13-C15 fatty acid is unsaturated. The unsaturated C13-C15 fatty acid can be selected from the group consisting of tridecenoic acid, myristoleic acid (tetradecenoic acid) and pentadecenoic acid.

It is more preferable that the (b) C 13 -C 15 fatty acid be myristic acid.

The amount of the (b) C13-C15 fatty acid in the composition according to the present invention may be 1% by weight or more, preferably 3% by weight or more, more preferably 5% by weight or more, and even more preferably 6% by weight or more, relative to the total weight of the composition.

On the other hand, the amount of the (b) C13-C15 fatty acid in the composition according to the present invention may be 20% by weight or less, preferably 15% by weight or less, more preferably 10% by weight or less , and even more preferably 8% by weight or less, relative to the total weight of the composition.

The weight ratio of the amount (weight) of the (b) C13-C15 fatty acid/the amount (weight) of the (a) modified starch may be 1.1 or more, preferably 1.2 or more, and more preferably 1.3 or more.

The (a) modified starch and the (b) C13-C15 fatty acid may form a complex.

(Clay)

The composition according to the present invention includes (c) at least one clay. A single type of clay may be used, or two or more different types of clays may be used in combination.

The term "clay" refers to a naturally occurring material composed primarily of fine-grained minerals, which is generally plastic at an appropriate water content and will harden when dried or fired. Although clay usually contains phyllosilicates, it may contain other materials that impart plasticity and harden when dried or fired. Associated phases in clay may include materials that do not impart plasticity and organic matter. A common definition is that in the Penguin Dictionary of Science, namely "finely divided rock materials whose component minerals are various silicates, mainly of magnesium or aluminium". Clay including Kaolinite (typically defined as [Si 4 ]Al 4 0io(OH) 8 .nH 2 0 (n=0 or 4)), Illite (typically defined as

M x [Si6.8Ali.2]Al 3 Fe.025Mg.75O20 (OH), Vermiculite (typically defined

as .M [Si7Al]AlFe.o5Mgo.502o (OH”, Smectite (typically defined as

M x [Si8]Al3.2Feo.2Mgo.602o (OH» and Chlorite (typically defined as

(Al(OH)2.55)4[Si6.8AlOl.2}Al3.4Mg0.6)20(OH) 4 ).

Another definition, frequently used by chemists is "a naturally occurring sediment or sedimentary rock composed of one or more minerals and accessory compounds, the whole usually being rich in hydrated aluminum silicate, iron or magnesium, hydrated alumina, or iron oxide, predominating in particles of colloidal or near-colloidal size, and commonly developing plasticity when sufficiently pulverized and wetted" (see Kirk-Othmer,

Encyclopaedia of Chemical Technology, Volume 5, page 544, 2nd edition, John Wiley and Sons, Inc., New York, NY 1964). Example of clays are given in the book "Clay mineralogy, S. Caillere, S. Henin, M. Rautureau, 2nd edition 1982, Masson". Clays may be of natural or synthetic origin.

Hydrophilic clay includes smectites such as saponites, hectorites, montmorillonites, bentonites, beidellite. Hydrophilic clay includes synthetic hectorites (also called laponites) such as the products sold by the company under the name Laporte Laponite XLG, Laponite RD, Laponite RDS (these products are sodium silicates and magnesium silicates in particular sodium, lithium and magnesium) bentonites such as the product sold under the name

Bentone® HC Rheox, magnesium silicates and aluminum products such as hydrated products sold by Vanderbilt Company as ultra Veegum®, Veegum® HS, Veegum® DGT, or calcium silicates, particularly the synthetic form sold by the company under the name Micro-Cel® vs.

Fuller's earth consists chiefly of hydrated aluminum silicates that contain metal ions such as magnesium, sodium, and calcium within their structure. Montmorillonite is the principal clay mineral in fuller's earth, but it may contain other minerals such as kaolinite, attapulgite, and palygorskite among other components.

Lipophilic clay means clay swellable in a lipophilic medium, the clay swells and forms a colloidal dispersion. Lipophilic clays include modified clays such as the modified

magnesium silicate (Bentone gel VS38 from Rheox) hectorites modified with an ammonium chloride fatty acid CIO to C22, such as hectorite modified with ammonium chloride distearyldimethylammonium (CTFA name: Disteardimonium hectorite) sold under the name "Bentone 38 CE" by Rheox or Bentone® 38V by ELEMENTIS.

The origin of such clay can be natural or synthetic mineral clay such as hectorite, bentonite, and quatemized derivatives thereof, for example which are obtained by reacting the minerals with a quaternary ammonium compound, such as stearalkonium bentonite, hectorites, quatemized hectorites such as Quatemium -18 hectorite, carbonates such as propylene carbonate, bentones, and the like.
