Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to compositions for application to and care of human hair. More particularly, the present invention relates to improved compositions for conditioning hair.

Products that improve the appearance, feel and style of hair are gaining increasing acceptance and popularity with consumers. The use of such compositions is particularly essential for use in hair treatments such as permanent waving, hair dyeing, tθasing, and bleaching. The physical condition of the hair can also be influenced by atmospheric conditions, such as sunlight, which can result in photocatalytic oxidation. These factors can result in poorly textured hair. This makes it difficult to condition and style the hair whether it is wet or dry.

Accordingly, compositions that condition hair generally improve hair conditionability, appearance, and feel by reducing drying static and increasing ease of combing both wet and dry hair. . Such Condeia-I Conde products are well known. Younger ones are "rinse-type" products that are applied to the hair and rinsed off, while others are "deep conditioners" that are left on the hair for longer periods of time.
itioners). Many conditioning products contain long quaternary ammonium compounds in combination with fatty substances such as fatty alcohols.

Such compositions are described, for example, in U.S. Pat. No. 3,155,5
No. 91 Liu and US Pat. No. 4,269,824. Such products have particularly good cosmetic and rheological properties, but leave the hair greasy or oily and are prone to restaining with dirt and sebum. These undesirable characteristics are
Disadvantageously associated with conditioning benefits.

The reason is that such products (known in the art) inherently deposit both vehicle and conditioning actives onto the hair.

A variety of compositions have been developed that attempt to provide favorable conditioning benefits while maintaining acceptable cosmetic and rheological properties. In particular, volatile silicone oils are well known for use in conditioning products. For example, British Patent No. 1,598,567 discloses hair conditioners containing volatile silicones and surfactants (the essential features of these compositions being that they contain fatty substances and (contains no quaternary ammonium compounds). British Patent No. 999,222 discloses the incorporation of organosilicone in a water-alcohol mixture for use as a hair conditioner. U.S. Patent No. 4,374
No. 825 discloses conditioners containing a hydrocarbon or silicone conditioning agent, a nonionic water-soluble thickening agent, and a cationic conditioning agent.

US Pat. No. 4,387,090 discloses conditioning compositions containing a volatile hydrocarbon or silicone conditioning agent and a polymeric thickener. GB 2,066.659 discloses a comb hair rinse composition comprising quaternary ammonium salts, a silicone material, and propylene glycol.

dimethicone copolyol (dimethicone copolyol) in a gel vehicle consisting of a lipid material and a cationic surfactant.
It has now been discovered that hair conditioning formulations containing silicone conditioning agents (ne copolyol) and silicone conditioning agents have improved hair care benefits while maintaining excellent in-use properties. In bamboo, such compositions exhibit less restaining of the hair after use than similar compositions that do not contain dimethicone copolyol. Thus, such products provide excellent conditioning benefits with low resoiling while maintaining favorable rheology.

A SUMMARY OF THE INVENTION The present invention provides: (a) a silicone conditioning agent of about 0.14 g;
~about 10%, (bl dimethicone copolyol about 0.01%~

cationic surfactant vehicle material from about 0.05% to about 5%, and (b3+) the balance water. Preferably, the lipid vehicle material is fatty alcohols or fatty esters. .

These products are preferably used as rinse-type conditioners. Thus, the present invention also provides a method of conditioning hair by applying a composition to freshly washed hair and rinsing the composition from the hair.

The conditioning composition of the present invention contains five essential ingredients: a silicone hair conditioning agent, a dimethicone copolyol, a lipid vehicle material, a cationic surfactant vehicle material, and water. These compositions include any composition intended for use on humans to condition hair. Depending on the particular conditioning benefits and product rheology desired, certain essential ingredients can be selected and other ingredients optionally included in preparing the final conditioning product. The remainder of the product is made up of water, preferably distilled water.

In particular, the hair conditioner of the present invention comprises (a)

The hair was washed for seconds and rinsed for 60 seconds after washing.

The wash/rinse/wash/rinse sequence was then repeated. One of compositions A, B, C or D was then applied to each hair piece of hair (a total of 5 hair pieces were used to evaluate each composition). Each test composition was thoroughly dispersed throughout each hairpiece, and the hairpieces were then rinsed for 30 seconds (gloves were worn throughout the treatment sweep and shaken between each product treatment). The hairpieces were then air-dried. O samples were cut from each dried hairpiece, placed in a tared vial, and weighed. Suitable solvents, such as methylene chloride/methanol 90:10 solvent mixture 10

It was significantly different from ν which adheres from silicone (no 1' coalescence). Thus, this data demonstrates that the dimethicone copolyols of the present invention significantly reduce the amount of cationic surfactant vehicle material deposited on the hair during use. This data also shows that the dimethicone copolyol material is not deposited per se. Therefore, this data demonstrates that dimethicone copolyol reduces undesirable deposition of vehicle materials on treated hair without significantly reducing deposition of silicone conditioning agents.

Experiment ■ Four formulations (A, B, C! and D) were prepared. Each was identical to that tested in Experiment I. The composition was applied to the hairpiece. After the hairpieces were stained with synthetic sebum, the hairpieces were graded by an expert judge to determine the cleanliness/soiling of the abyss.
