Abstract:
1. An ordered liquid crystalline phase cleansing composition comprising: (a) about 3 to 30% by weight of a surfactant system including at least one surfactant selected from an anionic, amphoteric, cationic and nonionic surfactant and mixtures thereof, wherein at least one anionic surfactant must be present; (b) about 0.1% to 15% by wt. of an ordered liquid crystalline phase inducing structurant; (c) about 0.1% to 10% of a cationic polymer; (d) at least 0.5% by wt. of a solid particulate optical modifier for exhibiting a specific set of optical properties on skin characterized by a positive result obtained by one or more skin evaluation methods selected from Tile evaluation method, Hand wash (consumer evaluation) method, or Hand wash (lab evaluation) method and wherein the particulate optical modifier contains a surface modification selected from the group consisting of amino acids, proteins, fatty acids, lipids, phospholipids (lecithin), anionic and/or cationic oligomers/polymers or blends or derivatives thereof to enhance the deposition of the optical modifier on to the skin; (e) wherein said ordered liquid crystalline phase composition has a viscosity of about 40,000 to about 300,000 cps at 25 C as measured via the T-bar method; and (f) wherein said ordered liquid crystalline phase composition contains less than about 0.025% by weight of an organic, non crosslinked, cationic homopolymer or copolymer having a cationic charge density of from about 2 meq/gm to about 10 meq/gm and an average molecular weight of from about 1,000 to about 5,000,000.
