HINDUSTAN UNILEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 and having its registered office at Hindustan Lever House, 165/166, Backbay Reclamation, Mumbai -400 020, Maharashtra, India
The following specification particularly describes the invention and the manner in which it is to be performed

WO 2006/087086

PCT/EP2006/000771

LIQUID CLEANSING COMPOSITION WITH UNIQUE SENSORY PROPERTIES
The present invention relates to detergent compositions
suitable for topical application for cleansing the human
body, such as the skin and hair. In particular, it relates
to stable liquid cleansing compositions containing a
specific combination of polyol(s), monoalkyl
sulfosuccinate(s) , n-acyl amino acid surfactant(s) and
optionally monoallkyl phosphate(s).

Prior art skin cleansers modify the way the skin feels after
the shower by depositing materials such as oils or polymers.
However, such cleansers often have disadvantageous sensory
or physical properties, such as a slimy feel and/or poor
lather. Stability problems are observed with other
combinations of hydrophilic emollients and surfactants.
EP patent application No.1235890 entitled Stable, High Glycerol Liquids Comprising N-Acyl Amino Acids and/or Salts
and issued to Arai et al. discloses high content glycerol liquid compositions comprising N-acyl amino acids and/or salts and defined sulfosuccinic acid monoesters, and a method of enhancing the stability of high content glycerin compositions comprising N-acyl amino acids or salt's thereof
and sulfosuccinic acid monoesters.
Surprisingly it has been discovered that by incorporating specific emollients and surfactants in specific amounts in a cleanser formulation, excellent sensory and lather properties' can be obtained simultaneously.

30 The inventive cleansing composition preferably possesses an ordered liquid crystalline microstructure, preferably a

WO 2006/087086

PCT/EP2006/000771

- 18 -
lamellar microstructure structure. The rheological behavior of all surfactant solutions, including liquid cleansing solutions, is strongly dependent on the microstructure, i.e., the shape and concentration■of micelles or other self-5 assembled structures in solution.
When there is sufficient surfactant to form micelles (concentrations above the critical micelle concentration or CMC), for example, spherical, cylindrical (rod-like or
10 discoidal), spherocylindrical or ellipsoidal micelles may
form. As surfactant concentration increases, ordered liquid crystalline phases such as lamellar phase, hexagonal phase, cubic phase or L3 sponge phase may form. The lamellar phase, for example, consists of alternating'surfactant
15 bilayers and water layers. These layers are not generally flat, but fold to form submicron spherical onion like structures called vesicles or liposomes. The hexagonal phase, on the other hand, consists of long cylindrical micelles arranged in a hexagonal lattice. In general, the 20 microstructure of most personal care products consist of either spherical micelles; rod micelles; or a lamellar dispersion.
As noted above, micelles may be spherical or rod-like.
25 Formulations having spherical micelles tend to have a low viscosity and exhibit Newtonian shear behavior (i.e., viscosity stays constant as a function of shear rate; thus, if easy pouring of product is desired, the solution is less viscous and, as a consequence, it doesn't suspend as well).
30 In these systems, the viscosity increases linearly with surfactant concentration.

WO 2006/087086

PCT7EP2006/000771

- 19 -
Rod micellar solutions are more viscous, because movement of the longer micelles is restricted. At a critical shear rate, the micelles align and the solution becomes shear thinning. Addition of salts increases the size of the rod 5 micelles thereof, increasing zero shear viscosity (i.e., viscosity when sitting in a bottle) which helps suspend particles, but also increases critical shear rate (i.e. the point at which the product becomes shear thinning; higher critical shear rates means the product is more difficult to 10 pour).
Lamellar dispersions differ from both spherical and rod-like micelles because they can have high zero shear viscosity (because of the close packed arrangement of constituent 15 lamellar droplets), yet these solutions are very shear thinning (readily dispense on pouring). That is, the solutions can become thinner than rod micellar solutions at moderate shear rates.
20 In formulating liquid cleansing compositions, therefore, there is the choice of using' rod-micellar solutions (whose zero shear viscosity,-e.g., suspending ability, is not very good and/or are not very shear thinning); or lamellar dispersions (with higher zero shear viscosity, e.g. better
25 suspending, and yet are very shear thinning). Such lamellar compositions are characterised by high zero shear viscosity (good for suspending and/or structuring) while simultaneously being very shear thinning such that they readily dispense in pouring. Such compositions possess a
30 "heaping", lotion-like appearance, which conveys signals of enhanced moisturization.

WO 2006/087086

PCT/EP2006/000771

- 20 -
When rod-micellar solutions are used, they also often require the use of external structurants to enhance viscosity and to suspend particles (again, because they have lower zero shear viscosity than lamellar phase solutions). 5 For this, carbomers and clays are often used. At higher shear rates (as in product dispensing, application of the product to the body, or rubbing with hands), since the rod-micellar solutions are less shear thinning, the viscosity of the solution stays high, and the product can be stringy and
10 thick. Lamellar dispersion based products, having higher zero shear viscosity, can more readily suspend emollients, and are typically more creamy. In general, lamellar phase compositions are easy to identify by their characteristic focal conic shape and oily streak texture, while hexagonal
15 phase exhibits angular fan-like texture. In contrast, micellar phases are optically isotropic.
It should be understood that lamellar phases may be formed in a wide variety of surfactant systems using a wide variety
20 of lamellar phase "inducers" as described, for example, in U.S. Pat. No. 5,952,286 issued to Puvvada, et al., on September, 14, 1999. Generally, the transitions from micelle to lamellar phase are functions of effective average area of headgroup of the surfactant, the length of the
25 extended tail, and the volume of tail. Using branched
surfactants, or surfactants with smaller headgroups or bulky tails are also effective ways of inducing transitions from rod micellar to lamellar.
30 One way of characterizing ordered liquid crystalline
dispersions includes measuring viscosity at low shear rate

PCT7EP2006/000771

- 21 -
(using for example a Stress Rheometer) when additional inducer (e.g., oleic acid or isostearic acid) is used. At higher amounts of inducer, the low shear viscosity will significantly increase. 5
Another way of measuring ordered liquid crystalline dispersions is using freeze fracture electron microscopy. Micrographs generally will show ordered liquid crystalline microstructure and close packed organization of the lamellar 10 droplets (generally in size range of about 2 microns).
In a preferred embodiment, the inventive ordered liquid crystalline phase composition preferably has a low shear viscosity in the range of about 40,000 to about 300,000 15 centipoises (cps) measured at 0.5 RPM using T-bar spindle A at 25°C using the procedure described below. More preferably the viscosity range is about 50,000 to about 150,000 cps.
