Sodium Stearate OP-100 V MB

INCI Name: Sodium Stearate
Product Code: 0284
CAS #: 822-16-2
EINECS: 212-490-5
Brand: OP™

Sodium Stearate OP-100 V is a vegetable-derived sodium stearate consisting primarily of the sodium salts of saturated C16 and C18 fatty acids. This fine white powder is used as a gelling agent in deodorant sticks (4 – 8%) as a structurant for bar soaps (5 – 20%) and as a co-emulsifier (<1%). Originally designed for alcohol-based deodorant sticks, it remains the preferred grade of sodium stearate for maximum stick clarity. Accelerate its dissolution by adding it to hot water (>80°C).
