Abstract

A personal care conditioning and/or styling composition for a keratin substrate comprising: (i) about 0.1 wt. % to about 20 wt. % of PolyAPTAC polymer; (ii) about 0.1 wt. % to 99.9 wt. % of water; (iii) at least one cosmetically acceptable excipient; (iv) optionally about 0.1 wt. % to about 1 wt. % of one or more natural or synthetic based monomer or polymer selected from the group consisting of anionic, cationic, non-ionic, amphoteric, hydrophobic, or zwitterionic in nature; and (v) optionally, at least one personal care active ingredient.

COMPOSITIONS COMPRISING CONDITIONING AND/OR STYLING POLYMER

FIELD OF THE INVENTION

[0001]    The present application relates to a personal care composition, and, more particularly, to a personal care composition comprising a conditioning and/or styling copolymer for a keratin substrate of hair and/or skin origin. 

BACKGROUND OF THE INVENTION

[0002]    Undamaged virgin hair is smooth and shiny; its cuticles on the surface of the hair lie down smoothly making the combing easy. The hair surface is also hydrophobic in nature preventing excessive water absorption during washing. When the hair is either mechanically or chemically damaged through bleaching, perming or coloring, the hair surface becomes rough and frizzy and difficult to detangle and comb. As the hair surface becomes more hydrophilic, the resulting hair fibers swell during washing, making the hair even more difficult to comb.

[0003]    Current conditioning and/or styling systems for regular and damaged hair generally use one or more combinations of cationic surfactants, amphoteric surfactants, silicones, fatty alcohols, polyquaterniums, amino acids, proteins, lipids and humectants. Wet conditioning of regular or damaged hair is accomplished by neutralizing the anionic charge of the hair by positively charged surfactants and polymers and creating a hydrophobic layer from surfactant and polymers. This hydrophobic layer results in a reduction of the swelling of the hair fibers by making the hair more hydrophobic and reducing friction of the hair fibers. An overall result of wet conditioning is improved detangling, manageability and soft feel of the hair. Upon treatment with cleansing systems like shampoos, 2/1 shampoos, body washes or shower gels, the combing performance, detangling properties, hydrophobicity of the hair and lubricity are not maintained sufficiently.

[0004]    A particular challenge for a personal care product developed for damaged hair is to condition hair damaged by heat, or damaged mechanically or chemically through bleaching or coloring the hair. Consumers desire to have existing damage to the hair be repaired and to prevent further damage to the hair from occurring. It is desired that conditioned hair be easily manageable, feel-smooth, and be easy to detangle. However, if hair is over-conditioned, the hair is perceived as being weighed down.

[0005]    Silicones are traditionally used in hair care applications to provide conditioning properties such as ease of combing and detangling, color retention, smoothness and hydrophobicity. Silicones function by forming a film on the hair surface and depending on the nature of the silicone they are either self-deposited or they require additional cationic ingredients for deposition. It is desired to formulate conditioning systems having reduced or no silicones while still providing silicone’s benefits.  The conditioning composition presented in the invention provides improved or similar properties to silicon...
