A PERSONAL CARE COMPOSITION
FIELD OF INVENTION
[0001] The embodiments herein generally relate to a personal care composition and
more particularly to a hair care composition that helps in hair care by providing
enhanced natural index.
BACKGROUND AND PRIOR ART
[0002] Personal care products are used for personal hygiene and beautification
purpose. Personal care product includes, for example, skin moisturizers, perfumes,
10 lipsticks, fingernail polishes, eye and facial makeup preparations, shampoos,
permanent waves, hair colors, toothpastes, and deodorants. Hair care is very
important to prevent hair from damaging as well as from fungal attack. Dandruff
appears to be one of a major causative agent for hair fall by affecting the scalp.
[0003] Currently, there are several methods and products for hair care, especially for
preventing and treating dandruff. Zinc pyrithione is a well known and widely used
active anti-dandruff and anti-fungal component of shampoos. However, zinc
pyrithione in combination with lipids and other preservatives (thiazolinone) are used
for treating dandruff. It is known that microbiological contamination can result in
poor shelf life and aesthetics of shampoos. Accordingly, preservatives are usually
added to the shampoo composition during the manufacture of the shampoo to reduce

or eliminate such contamination. As a result, preservatives are added to zinc pyrithione shampoo composition for keeping the shampoo active and protect from microbial contamination.
[0004] However, a problem with adding a synthetic preservative to zinc pyrithione shampoo composition is that the ingredients present in the shampoo composition may react adversely with the synthetic preservative and may undergo undesirable chemical changes and thereby may reduce its activity. Specifically, it has been found that zinc pyrithione reacts adversely with some synthetic preservatives that reduce its activity and in turn its ability to prevent or reduce microbiological contamination. Natural preservative are capable of controlling microbial activity, as well as retarding and eliminating the growth of topical pathogens and microbes and also capable of eliminating undesirable chemical changes when added to shampoo compositions. Therefore, inclusion of a natural preservative to the zinc pyrithione shampoo composition allows the shampoo composition to stay active and also protects from microbial contamination effectively and thereby eliminating any undesired chemical changes. Radish root ferment is a natural preservative widely used in skin care products. Radish root ferment as a preservative is water soluble, odorless and heat stable up to 60 degrees Celsius. It is known to have a wide spectrum of antimicrobial application and blends perfectly with other compounds. It is quite mild and has very low to no potential for irritation.

[0005] Therefore, there is a need for providing a personal care composition, more particularly a hair care composition comprising zinc pyrithione salt in combination with a natural preservative for enhancing natural index and attaining good anti-dandruff and anti-fungal efficacy without side effects.

[00011] In view of the foregoing, an embodiment herein provides a personal care composition, more specifically a hair care composition for enhancing anti-dandruff and anti-fungal efficacy. The term "hair care" includes preventing dandruff, fungal attack and providing hair conditioning.
[00012] According to an embodiment, the personal care composition comprises of a topical carrier, fine particle size (FPS) dispersion of zinc pyrithione salt and a natural 10 preservative.
[00013] According to an embodiment, the fine particle size dispersion of the zinc pyrithione salt includes water and solid particles of the zinc pyrithione salt based on a weight of the dispersion. The fine particle size dispersion of the zinc pyrithione salt includes at least 25%-50% of the solid particles of the zinc pyrithione salt. The composition includes at least 0.5%-5% of the fine particle size dispersion of the zinc pyrithione salts.
[00014] According to an embodiment, the natural preservative is radish root ferment filtrate. According to an embodiment, the personal care composition includes at least 2%-4% of radish root ferment filtrate. The solid particles of the zinc pyrithione salt are selected from a group consisting of monovalent and polyvalent zinc pyrithione

salts. The particle size of the solid particle of the zinc pyrithione salt is at least 5
microns.
[00015] According to an embodiment, the personal care composition is a shampoo
composition for enhancing natural index and attaining good anti-dandruff and
antifungal efficacy.
[00016] These and other aspects of the embodiments herein will be better
appreciated and understood when considered in conjunction with the following
description and the accompanying drawings. It should be understood, however, that
the following descriptions, while indicating preferred embodiments and numerous

BRIEF DESCRIPTION OF EMBODIMENTS
[00017] The embodiments herein and the various features and advantageous details
thereof are explained more fully with reference to the non-limiting embodiments that
are illustrated in the accompanying drawings and detailed in the following
description. Descriptions of well-known components and processing techniques are
omitted so as to not unnecessarily obscure the embodiments herein. The examples
used herein are intended merely to facilitate an understanding of ways in which the

embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein. [00018] As mentioned above, there is a need to develop a personal care composition
5 and more particularly a hair care composition comprising zinc pyrithione salt in combination with radish root ferment filtrate for enhancing natural index and attaining good anti-dandruff and anti-fungal efficacy.
[00019] Accordingly to an embodiment, the personal care composition comprises of a topical carrier, fine particle size (FPS) dispersion of zinc pyrithione salt and a natural
10 preservative.
[00020] According to an embodiment, the fine particle size dispersion of the zinc pyrithione salt includes water and solid particles of the zinc pyrithione salt based on a weight of the dispersion. The fine particle size dispersion of the zinc pyrithione salt includes at least 25%-50% of the solid particles of the zinc pyrithione salt.

The solid particles of the zinc pyrithione salts preserved by the radish root ferment filtrate exhibit an antimicrobial efficacy which is neither

synergetic nor antagonistic in antimicrobial efficacy of a dispersion of solid particles of the zinc pyrithione salt. The radish roots are fermented in solid state using a Lactobacillus sp. In brine and the ferment filtrate containing bio actives with antimicrobial activity is suitably stabilized to an effective natural preservative formula for the personal care composition. The solid particles of the zinc pyrithione salt are selected from a group consisting of monovalent and polyvalent zinc pyrithione salts. The particle size of the solid particle of the zinc pyrithione salt is at least 5 microns.
[00022] According to an embodiment, the personal care composition is a shampoo composition for enhancing natural index and attaining anti-dandruff and antifungal efficacy.
[00023] The following table illustrates a additional components in the fine particle size (FPS) dispersion of zinc pyrithione salt:

Appearance Clear to slightly hazy liquid
Color Yellow to light amber
Odor Characteristic
Solids (lg-105°C-lhr) 25 - 30 %
pH 4.0-6.0
0
Specific gravity (25 C) 1.0-1.1
