Sodium stearate is a versatile ingredient derived from either animal or vegetable sources. It is commonly used in skincare products as an emulsifier, dispersant, gelling agent, stabilizer, binder, and viscosity modifier. It is a major component of soaps, cosmetics, and food additives. It can be used to adjust the viscosity and stiffness of a formulation and may also lend itself waterproofing qualities. Sodium stearate is also used in bar soaps and cleansers, where it acts as a surfactant to help remove dirt and oil from the skin. It is also used in deodorants, toothpaste, makeup, body wash, facial cleanser, shampoo, and hair coloring. Sodium Stearate OP-200V is a vegetable-based sodium stearate, consisting primarily of the sodium salts of saturated C16 and C18 fatty acids, but also including a defined proportion of C20 and C22 fatty acids to increase the melt point and decrease the payout of hydroglycolic sticks made with it. Sodium Stearate OP-200V may find application as a gelling agent for deodorant and fragrance sticks, as a structurant for vegetable-based bar soaps, and as a viscosifier or emulsion stabilizer for other aqueous-based personal care products.

Sodium stearate can leave a residue, which could potentially clog pores. Bar cleansers/soaps tend to be drying on skin.
Sodium stearate in powder form presents an explosive hazard and should only be handled while wearing a respirator. Gloves and other personal protective equipment should be worn at all times, as well as antistatic working shoes.
Sodium stearate can be derived from either animal or vegetable sources. It is supplied as a white powder in its raw material form. Sodium Stearate C-7 is a sodium salt of distilled hydrogenated fatty acids.
The CIR Expert Panel found Sodium Stearate to be safe as used at levels of up to 25%. See J. Amer. Coll. Toxicol. (JACT) 1(2): 143-77 (1982)

Sodium Stearate OP-200V may find application as a gelling agent for deodorant and fragrance sticks, as a component of vegetable-based bar soaps, and as a viscosifier or emulsion stabilizer for other aqueous-based personal care products. Originally designed for Propylene Glycol-based deodorant sticks, it remains the preferred grade of Sodium Stearate for nonalcoholic sticks. Typical use levels: underarm deodorants: 4 – 8%; bar soaps: 5 – 20%; emulsion stabilization: 0.5 – 1.5%.
