alternative solvent to Propylene Glycol or Glycerol superior in technological and biological effects. Viscosity decreasing. As humectant, it prevents the drying out of cosmetics. It prevents the assimilation of water from atmospheres of high humidity into film-forming preparations. Prevents crystallization of insolubles
Compared with Glycerol, Sorbitol, and Propylene Glycol, more efficient polyol as antimicrobial agent. inhibits gram-positive and gram-negative microorganisms as well as molds and yeasts, but is not sporicidal. All polyols need a contact period of at least one week to exert their effect as preservatives.
optimal antimicrobial effect when e.g. added to an oil in water emulsion at 8 %. it has been shown to inhibit growth of escherichia coli, sal. typhiosa and pseudomonas aeruginosa, whereas funghi areinhibited only above 17 %.
