English description（英文原文，共 1234 字符）
Product Name:Propylene Glycol Stearate
English Name:Propylene Glycol Stearate
CAS No.:1323-39-3
Aliases:Propylene glycol ester, Propylene glycol fatty acid ester, Propylene glycol monostearate
Molecular Formula:C21H42O3
Physical Properties:The appearance varies with the fatty acid composition, ranging from white to yellow solids or viscous liquids, and it is odorless. Pure propylene glycol monostearate is a white solid with an HLB value of about 3.4. It is a lipophilic emulsifier, insoluble in water, soluble in ethanol, ethyl acetate, chloroform and other organic solvents, and can be emulsified by vigorous stirring with hot water.
Uses:Mainly used as an emulsifier, defoaming agent and stabilizer. Due to its low HLB value, its emulsifying activity is weak when used alone, so it is often combined with other emulsifiers such as mono- and diglycerides. It is used in margarine, shortening, ice cream, pastry and other foods to prevent water separation and spattering, retard starch retrogradation, and improve the overrun and shape retention of ice cream.
Technical Specifications:
Acid value (as KOH) ≤ 5.0 mg/g
Iodine value ≤ 3.0 g/100g
Solidification point ≤ 45℃
Lead (as Pb) ≤ 0.0005%
Arsenic (as As) ≤ 0.0001%
