Polysaccharides: “Naturals” for Cosmetics ad Pharmaceuticals

  • George L. Brode

Abstract

Certain polysaccharides and polysaccharide derivatives are “natural” products for use in cosmetic and therapeutic applications. Polysaccharides are ubiquitous in nature, found extensively in both plants and animals. Largely of carbohydrate structure, this class of polymers is essentially derived from sugar-type molecules by cyclodehydration/addition reactions. Polymer properties and the resulting formulations containing them depend on several key structural parameters, including: (1) molecular weight and molecular weight distribution; (2) conformation and stereochemistry in the monomeric and oligomeric repeat units; (3) type of functional group(s); (4) derivatization - both the type and distribution; (5) charge density and distribution in ionic polymers; (6) hydrophile/lipophile ratios and distribution patterns, etc. These factors are discussed with a view to capitalizing on those features important for cosmetic and therapeutic applications. Emphasis is placed on cellulose derivatives, chitin/chitosan, and hyaluronic acid.
