R: C12-18.
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
> 93
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.
