Products Description

Molecular formula: C7H11O6 - R

Molecular weight: 346.45 - 957.46
Properties: Can be mixed with various surfactants, especially suitable for use with Tween-60 (T-60), and the combined effect is better when used in combination. HLB (Hydrophilic-Lipophilic Balance) value is 4.7, melting point is 52 - 57℃.
Function and effect: It is an ester formed by sorbitol and different higher fatty acids, such as Span-20 (SP-20) is a lauric acid ester; Span-80 (SP-80) is a monolauric acid ester. It has emulsifying effect.
Usage and dosage: For preparing water-in-oil emulsions.
The original process of Span-80 is to use vacuum esterification method. During the reaction, the water generated in the reaction is constantly removed to facilitate the formation of a favorable reaction equilibrium in the direction. However, due to the high reaction temperature and the relatively low water vapor partial pressure in the reaction system (less than 40 mmHg), the control of side reactions is extremely difficult, resulting in extremely unstable product quality, large variation in viscosity, and poor emulsifying performance.

Span 20

CAS Number: 1338-39-2 Appearance

Properties: Transparent colorless liquid

Xylitolan di-lauroylate is an organic compound with the chemical formula C18H34O6. It is a pale yellow oily liquid that can dissolve in organic solvents and oils, and forms a semi-gel solution in water. It is produced by dehydrating and closing a ring from xylitol, and then reacting with lauric acid for esterification. It is mainly used in cosmetics, medicine, and the textile industry, as an oil-in-water emulsifier, wetting agent, and mechanical lubricant, etc. It is a non-ionic surfactant and is used as an emulsifier, stabilizer, thickener, lubricant, softener, antistatic agent, dispersant, solvent aid, rust inhibitor, finishing agent, and spinning aid, etc.

Span 60

Shirahama Tan Mono Stearate is an organic compound with the molecular formula of C24H46O6. The pure form is a beige flake or brownish waxy substance. It is non-toxic. The relative density ranges from 0.98 to 1.03. It is insoluble in cold water, glycerol, ethanol, isopropanol, paraffin oil, soybean oil and lard oil. It forms a gel in hot water and can be dispersed in hot glycerol. It appears turbid in hot xylene. It belongs to non-ionic type surfactants. It is an oil-in-water emulsifier. Its LD50 for mice orally is >15000 mg/kg, and the ADI value is 0 - 25 mg/kg. It is obtained by esterification reaction of stearic acid and sorbitol in the presence of sodium hydroxide, followed by bleaching and slicing [1]. It is used as an emulsifier and defoamer in the industries of pesticides, plastics, cosmetics, medicine, coatings, textiles, and food.
