Description
Sodium Laurate Product Overview
Sodium laurate (C12H23NaO2) is a white to off-white powder that dissolves in warm water and forms a clear, foaming solution. It is the main soap component obtained from coconut and palm kernel oils, which are rich in lauric acid.
Its short C12 chain gives quick, abundant lather and good solubility even in cooler water. Soap makers therefore use it in bar soaps, liquid soaps and shaving products, and cosmetic formulators use it in cleansing creams and as an emulsifier. Compared with synthetic surfactants such as Sodium Lauryl Ether Sulfate, it is a classic soap and works best at alkaline pH.
High-purity grades also find use in laboratories, for example as a cleavable surfactant in protein sample preparation, and as a raw material for other laurate salts. Related metal soaps include Zinc stearate and Magnesium stearate.

Frequently Asked Questions
Why does sodium laurate lather so well?
Its relatively short C12 chain makes it soluble and quick to foam, even in cooler water, which is why coconut-based soaps lather strongly.
Can sodium laurate be used in acidic formulations?
No. Like all soaps, it converts back to lauric acid at low pH and loses its cleansing ability. It works best at alkaline pH.
How can I get a price and documents?
