Sodium Isotrideceth Sulfate
Alias
Sodium Trideceth Sulfate
Category
Anionic surfactants-Sulfate
CAS No.
 
Structural Formula
R: iso-C13.
Properties
Appearance: (1), paste; (2), transparent liquid; (3), solid.
Solubility: soluble in water.
Stability: stable in alkali, weak acid and hard water; unstable in strong acid.
Risk: irritation, irritation to skin, eye.
Animal toxicology: 1,4-dioxane generated during preparation: probable carcinogen. However, can be acceptable when concentration of 1,4-dioxane is less than 30ppm or less.
Ecology: May be hazardous to environment. Water body should be given special attention.
Biodegradability: Biodegradable.
Characteristics: excellent cleansing, solubilizing, dispersing, emulsifying, foaming, foam stabilizing abilities. good resistance to hard water.
Notes: products that has low 1,4-dioxane can used in children cleaning products. Based on  irritating judgment, usage should not exceed 10%. In no tears formula of children shampoo, may be difficult to use as a primary surfactant.
