Frequently Asked Questions
Sorbitan Tristearate, sold as SOL STS or Emulsifier E 492, is produced by esterifying sorbitol with commercial stearic acid. It appears as a light cream powder or flakes with a slight characteristic odor and bland taste, and it is USP compliant.
STS functions as an antiblooming agent in chocolate and an anticrystallization agent in oils, helping maintain a smoother, more stable fat structure that resists the visible white or grey bloom that can develop on chocolate surfaces over time.
Beyond chocolate, STS is used as an antisandiness agent in margarines, helping prevent the gritty crystalline texture that can otherwise develop, in addition to select cosmetic applications.
