ABSTRACT:

TECHNICAL FIELD
The present invention relates to hair styling compositions comprising water soluble, non-polymeric mineral salts and lipophilic materials which provide improved hair styling. Specifically, the present invention relates to hair styling compositions comprising water soluble, non-polymeric mineral salts and lipophilic materials further comprising low levels of a dispersing surfactant for improved hair styling.
BACKGROUND OF THE INVENTION
Hair styling compositions, such as hair sprays, styling gels, spray-on gels, and mousses are used on hair to hold the hair in a particularly desired shape or arrangement. A hair arrangement having improved lift, volume and fullness is often a desirable attribute, particularly among consumers with fine, limp or less voluminous hair. Conventional volumizing products generally provide such lift, fullness, control and styling by using fixative resins and polymers. However, these products can be perceived as imparting to hair a stiff, tacky, sticky type of texture, leaving the hair feeling overly coated and rough to the touch.
Chemical processing such as perming, bleaching, highlighting, coloring, and straightening is also a means whereby fullness and volume can be imparted to hair. However, styles typically controlled using such methods are not easily changeable and are frequently time consuming and labor intensive. Moreover, the chemicals employed in such methods can be caustic and somewhat damaging to hair when used excessively.
Mineral salts have been known to be useful as a means of increasing the viscosity of formulations and emulsions when combined with surfactants as disclosed in
Encyclopedia of Shampoo Ingredients
(A. L. L. Hunting, Micelle Press, 1983).
Encyclopedia of Conditioning Rinse Ingredients
(A. L. L. Hunting, Micelle Press, 1987).
Compositions containing water soluble, non-polymeric mineral salts have also been described as styling aids. For example, German Patent, DE 2,608,649 to Schulz discloses fat (oil) free compositions which incorporate water soluble, non-polymeric mineral salts to provide a lighter, looser setting of the hair. Schulz, however, fails to address compatibility issues which arise upon incorporating conventional oil or oil-like substances such as preservatives, perfume oils, vitamins, botanical extracts, fatty alcohols and the like. Such lipophilic substances have limited solubility in water. And, as such, tend to aggregate or “clump” in aqueous environments, resulting in decreased styling efficacy.
Therefore, a need exists for improved hair styling compositions containing water soluble, non-polymeric mineral salts which also provide for the uniform distribution or dispersion of aesthetic and/or antimicrobial, lipophilic materials. The present inventors have discovered that the use of low levels of surfactants in mineral salt solutions provide for the even and uniform dispersion of added lipophilic materials resulting in improved hair styling benefits.
It is therefore an object of the present invention to provide compositions having improved styling benefits of fullness and volume without leaving the hair sticky, stiff or coarse.
It is also an object of the present invention to provide improved hair styling compositions comprising a water soluble, non-polymeric mineral salt, lipophilic materials and low levels of surfactant to uniformly disperse the lipophilic material.
It is also an object of the present invention to provide improved hair styling sprays, foams, mousses, lotions, gels and creams comprising a water soluble, non-polymeric mineral salt, lipophilic materials and low levels of surfactant to uniformly disperse the lipophilic material which provide cleaner feeling hair without stiffness or stickiness under a variety of humidity conditions.
It is further the object of the present invention to provide an improved method for styling hair.
These and other objects will become readily apparent from the detailed description which follows.
SUMMARY OF THE INVENTION
The compositions of the present invention relate to hair styling compositions, comprising:
a.) from greater than 0.5% to about 5% by weight of the composition of a friction enhancing agent which is a water soluble, non-polymeric mineral salt;
b.) from about 0.05% to about 0.5% of by weight of the composition of a lipophilic material;
c.) from about 0.01% to about 0.5% by weight of the composition of a surfactant selected from the group consisting of amphoteric, anionic, nonionic and mixtures thereof wherein the nonionic surfactant has a formula selected from the group consisting of:
 R

 and mixtures thereof where R is a long chain alkyl group or mixer of alkyl groups containing 10-24 carbon atoms; X is a phenyl,
>c=o
, sulfur or nil; Y is a hydrogen or methyl; and n is an integer from 1 to 20, preferably from 2 to 15, and most preferably from 2 to 10; when X is nil, R is bonded directly to
 and wherein R
1

and
d.) water

and wherein the composition has a hair friction index of at least 1.07.
The present invention further relates to methods of using the hair styling compositions.
DETAILED DESCRIPTION OF THE INVENTION
The hair styling compositions of the present invention can comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well any of the additional or optional ingredients, components, or limitations described herein.
All percentages, parts and ratios are based upon the total weight of the personal cleansing compositions of the present invention, unless otherwise specified. All such weights as they pertain to listed ingredients are based on the active level and, therefore, do not include carriers or by-products that may be included in commercially available materials, unless otherwise specified.
The compositions of the present invention preferably contain less than 0.2% of an insoluble, inorganic salt complex. The term “insoluble inorganic salt complexes”, as used herein, wherein the solubility of the inorganic salt complex is less than 0.5% in water at ambient temperature and pressure (25° C., 1 atmosphere pressure) includes but is not limited to, clays, bentonite, ceramic, kaolin, slip clays, polyorganosilicates, kaolinite, montmorillonite, atapulgite, illite, bentonite, halloysite, silica, alumina, mudds and polyphosphates.
The phrase “leave-on”, as used herein, means compositions which are intended to be applied to hair, wet or dry and left on the hair during subsequent drying or styling. The compositions of the present invention are preferably leave-on compositions.
The compositions of the present invention contain less than about 0.2% of a chemical protein modifying agent, preferably less than about 0.15%, more preferably less than about 0.1%. The phrase “chemical protein modifying agent,” as used herein means any chemical agent known to alter the chemical bond structure of the hair's protein in such a way as to lead to oxidative or reductive changes to bond links within the hair. Examples of, but not limited to, chemical protein modifying agents including ammonium thiglycolate, dithiothreitol,
1-3
-dithiopropanol, glycerylmonothioglycolate, permanganate, peracetic acid, hydrogen peroxide, sodium thiosulfate, potassium sulfit
