May 20, 2005· polysorbates. The sorbitan fatty acid esters are mono-, di-, and triesters of fatty acids (such as lauric, stearic, palmitic and oleic acids) and sorbitan. Sorbitan is a generic name for anhydrides derived from sorbitol, a naturally occurring crystalline hexahydric alcohol found in fruits, seaweed, and algae (CIR 2000).
Oral gavage studies for 28 days at dose levels up to 1000 mg/kg /day resulted in no systemic toxicity. Therefore, the NOAEL was 1000 mg/kg/day for this tetraester. Since the sesquioleate and trioleate of sorbitan are merely multiple ester homologs of sorbitan monooleate, they would be expected to show
efficacy of polyoxyethylene (20) sorbitan monooleate when used in feedingstuffs for all animal species. The additive is a mixture of the partial esters of sorbitol and its mono- and dianhydrides with edible commercial oleic acid and condensed with approximately 20 moles of ethylene oxide per mole of sorbitol and its anhydrides.
DEFINITION Consists of a mixture of the partial esters of sorbitol and its mono- and dianhydrides (which have an acid value below 7.5 and a water content below 0.2%) with edible commercial oleic acid and condensed with approximately 20 moles of ethylene oxide per mole of sorbitol and its anhydrides. C.A.S. number 9005-65-6

May 20, 2005· Polysorbates are composed of 1 or 3 moles of a fatty acid such as lauric, palmitic, stearic, or oleic and up to 20 moles of ethylene oxide per mole of sorbitol and its anhydrides. They are viscous, oily liquids or waxy solids soluble or dispersable in water and possessing a faint characteristic odor. 11.

Tween 20 is a polyoxyethylene sorbitan monolaurate compound with 20 ethylene oxide units, 1 sorbitol unit, and 1 lauric acid group esterified as the hydrophobic tail. The fatty acid group avidly adsorbs to the carbon nanotube surface, leaving the three PEG arms, each containing terminal hydroxyl groups, sticking out from the coating to create .
This is a safety assessment of polysorbates as used in cosmetics. These ingredients mostly function as surfactants in cosmetics. The safety assessment combined the polysorbates reviewed in 3 former safety assessments with polysorbates that had not been assessed for safety into 1 report. The Panel reviewed relevant data related to these ingredients.
