Cationic cassia derivatives and applications therefor

Disclosed are sunscreen compositions comprising zinc oxide and at least one of an effective amount of carbomer and an effective amount of C to C alkyl acrylate crosspolymers. The compositions most preferably utilize an oil in water emulsion. Also disclosed are related processes for producing and using such compositions.

Sunscreen composition

A novel hydrophilic ampholytic polymer synthesized by reacting polymerizable amino and carboxy functional ethylenically unsaturated monomers, together with a non-ionic hydrophilic monomer, to provide a polymer having a glass transition temperature (T ) above about 50&deg; C., and optionally hydrophobic monomer(s), and cross-linking monomer(s). The copolymer is precipitated from a polymerization media which includes a suitable organic solvent. The resulting copolymer is in the form of a fine powder, with submicron particle size. As such it is suitable for use as a thickener or rheology modifier in personal care formulations, such as shampoo, conditioner, and the like, as a bioadhesive, and for other pharmaceutical applications.

Hydrophilic ampholytic polymer

A blend of one or more crosslinked polymers or copolymers prepared from an olefinically unsaturated polymerizable carboxylic or anhydride monomer and at least one high molecular weight essentially linear polymer prepared from an olefinically unsaturated polymerizable carboxylic acid monomer. The blend is neutralized to typically a low pH, and generally contains a noncovalent, e.g. ionic, crosslinking agent, and a cure rate modifier. The hydrogel blend is capable of containing a large amount of water, has good tack, good adhesion, and can be utilized as an application vehicle having a backing thereon as well as containing various substances such as personal care compounds, pharmaceuticals, active ingredients, and the like.
