Isol. from the enzymatic hydrolysates of tamarind polysaccharide, Jack pine Pinus banksiana) glucomannan, leaves of Nicotiana tabacum, and other polysaccharide sources. Constituent in cell wall polysaccharide of immature barley plants. [a]o +74 (c, 0.5 in H2O) (+71). 

Chapter 8 is a review of the use of polysaccharides, perhaps some of the oldest and most well-known ingredients used in personal care. Because polysaccharides are derived from natural sources, the nature of the monosaccharides that comprise these sugar-based polymers and how nature designs the polysaccharides are addressed first. This discussion is followed by greater details of individual cosmetically important polysaccharides based primarily on the ionic nature of the polysaccharide, that is, anionic, cationic, nonionic, or amphoteric, which can be either naturally developed by the polysaccharide source or manipulated by human intervention and invention. The effects of hydrophobic modification of polysaccharides are also discussed. The chapter concludes with a brief discussion of certain polysaccharides that appear to have physiological effects on the human body when applied topically.

An underlying assumption is that dextran is a representative polysaccharide source and that results derived from studying its modification can be directly applied to other sources of polysaccharides. If dextran can be successfully modified utilizing a specific reaction system, other polysaccharides can likewise be modified using the same reaction system if that particular polysaccharide is soluble in the given reaction phase employed. Thus, polysaccharide solubility is the key factor in determining which reaction system can be employed.

The adoption of ternary polymeric systems including cellulosic nanoreinforcements and other nanoparticles leads to considerable assets in terms of multifunctionality, but also of tailored modification of the properties of the selected polymer matrix. A number of issues remain nonetheless open for discussion, particularly linked to the polysaccharides source from which nanocellulose is obtained, the process used to fabricate it and the strength of its interface with the polymer matrix and with the particles. This involves other aspects, such as the degree of hydrophilicity and the improvement of...
