Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 9005-67-8 differently. You can refer to the following data:
1. Tan paste
2. Polysorbate 60 has a faint, characteristic odor and a warm, somewhat bitter taste. It is a mixture of stearate and palmitate 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.

Uses

Different sources of media describe the Uses of 9005-67-8 differently. You can refer to the following data:
1. Lonzest(R) SMS-20 is used as an emulsifier for plastic & polymers, personal care and industrial applications.
2. Glycosperse(R) S-20 KFG is used as an emulsifier. Suggested applications: cakes, shortenings, milk substitute, chocolate flavored syrup. Product Data Sheet
3. azalide antibiotic
4. Tween 60 is an emulsifier manufactured by reacting stearic acid with sorbitol to yield a product which is reacted with ethylene oxide. It is a nonionic, waterdispersible surface-active agent which is very hydrophilic. It is also termed polysorbate 60. It is used in whipped vegetable toppings for overrun and lightness; in cakes for increased volume and fine grain; in icings and confectionery for lightness and syneresis control; and in salad dressing for emulsion stability. It is frequently used with sorbitan monostearate or monoand diglycerides. The typical usage range is 0.10–0.40%.

Definition

ChEBI: 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 stearate group.

General Description

TWEEN 60 is a niosome.

Flammability and Explosibility

Nonflammable

Safety Profile

Moderately toxic by intravenous route. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits acrid smoke and irritating fumes.
