About Potassium Stearate:
Potassium Stearate is a white crystalline powder. Easily soluble in hot water, insoluble in ether, chloroform and carbon disulfide. Its aqueous solution has strong alkalinity to litmus or phenolphthalein, and its ethanol solution has weak Alka.
What we usually call soap in our lives is a mixture of fatty acid sodium obtained by saponification of various fats and oils with sodium hydroxide. These fatty acid sodium are actually a comprehensive term for sodium stearate, sodium palmitate, sodium oleate, sodium linoleate and other fatty acid sodium.
If you do not use mixed oils in saponification, but only use a single stearic acid and sodium hydroxide (commonly known as caustic soda, caustic soda), you get sodium stearate soap; if you use stearic acid and potassium hydroxide for saponification, The result is potassium stearate soap. 
Compared with sodium soap, potassium soap has higher solubility and transparency, and less irritation. Feel free to send an inquiry to get the latest price if you would like to buy Potassium Stearate in bulk.

Properties of Potassium Stearate: 
Potassium stearate (CAS 593-29-3) is fine white powder; soluble in hot water and alcohol.

How is Potassium Stearate produced?
Potassium Stearate is the potassium salt of the fatty acid of stearic acid. It is derived from the saponification of vegetable oils. 

Potassium Stearate is derived from Stearic Acid—a byproduct of vegetable oil through the saponification process. Potassium Stearate is primarily used as a cleansing agent and emulsifier.
Applications of Potassium Stearate:
Potassium stearate can be used as a cleanser for hair, face and body, as well as a co-emulsifier for skincare products, cosmetics and hair styling products. At the same time, it has a good cleaning effect and can make the skin fresh and clean.
Potassium stearate is mainly used in cosmetics and skincare products as surfactants, cleansers, and emulsifiers. It has a risk factor of 1. It is relatively safe and can be used with confidence. Generally, it has no effect on pregnant women. Potassium stearate is not acne-causing.
Potassium stearate uses as a cleaning agent and emulsifier. It can be used in much personal care and cosmetic applications. It can also be used in certain rubber manufacturing and as a basis for textile softeners
