Chemische Eigenschaften
Polysorbate 20 is a mixture of laurate partial esters of sorbitol and sorbitol anhydrides condensed with approximately
20 mole of ethylene oxide (C2H4O) for each mole of sorbitol and its mono- and dianhydrides. It has a faint, characteristic odor and a
warm, somewhat bitter taste.
Verwenden
polysorbate 20 is a solubilizer, emulsifier, viscosity modifier, and stabilizer of essential oils in water.
Definition
ChEBI: Polysorbate 20 (Tween 20) is a polymer composed of PEG-ylated sorbitan, where the total number of poly(ethylene glycol) units is 20 (w + x + y + z = 20) and a single terminal is capped by a dodecanoyl group. It is a surfactant and emulsifier used in cleaners and personal care products.
synthetische
polysorbate 20 is prepared by condensing the partial esters of sorbitol and its anhydrides with ethylene oxide to effect an oxyethylene copolymerization at the free hydroxyl groups.
Allgemeine Beschreibung
Polysorbate 20 is a hydrophilic nonionic surfactant generally used as emulsifiers, dispersing agent and solubilizer.
Auswirkungen auf die Gesundheit
Polysorbate 20 was a skin irritant in dermatitis patients but was reported not to induce irritant responses when applied to the intact skin of health volunteers. It produced, at worst, minimal irritation in the eyes of rabbits. Only a small number of cases of skin sensitization have been reported in humans, although a moderate to strong sensitizing potential was seen in guinea-pigs treated by intradermal injection.
Sicherheitsprofil
Moderately toxic by
intravenous route. Mddly toxic by ingestion.
A human skin irritant. When heated to
decomposition it emits acrid smoke and
irritating fumes.
