Appearance (1), white to light yellow gelatinous colloid; (2), white to light yellow liquid; (3), solid.
Odor faint characteristic odor.
Solubility soluble in water.
Hygroscopicity Solid ammonium C12-18 alkyl sulfate: hygroscopic.
Physical - chemical properties
Flash point, °C
Stability pH: 4~7, stable. pH < 4: hydrolyzed, reduced to alcohol. pH > 7: release ammonia. Break down when heated to high temperature for a long time. Stable in hard water.
Risk Colloid or liquid form: irritation, moderate irritation to skin, eye. Compared with sodium C12-18 alkyl sulfate, ammonium C12-18 alkyl sulfate has lower toxicity and irritation.
GHS (Rev.6) label:
Ecology may be hazardous to environment. Water body should be given special attention.
Characteristics excellent foaming, cleansing, emulsifying, wetting, permeating, dispersing, solubilizing abilities. Resistant to hard water. Particularly suitable for preparation of a low pH value (neutral to weakly acidic) products.
