Structural Formula
 
R: C10-16.
Properties
Appearance: (1), white or yellow liquid or paste; (2), white or yellow powder or flaky solid.
Solubility: soluble in water.
Stability: stable in weak acid, weak alkali, hard water.
Risk: irritation, irritation to skin, eye.
Ecology: May be hazardous to environment. Water body should be given special attention.
Biodegradability: biodegradable.
Characteristics: excellent cleansing, foaming, emulsifying, solubilizing, dispersing abilities. moderate foaming. Foaming capacity is higher than benzene sulfonate in hard water. Mild. Cleansing capacity is higher than benzene sulfonate. When pH value is 6 to 8, formula is stable. suitable for preparation of neutral formula. Third representative surface active agents is used instead of alkylbenzene sulfonate (LAS). disodium 2-sulfo lauric acid should be strictly controlled in order to avoid affecting activity of product's surface.
Ingredients description: for solid products, content of sodium 1-methyl 2-sulfolaurate is not high, and its main purpose is need of processing washing powder.
Note: be careful to use in children washing products.
