What it is
Lauric Acid is a saturated 12-carbon fatty acid that occurs naturally in coconut and palm kernel oils. In cosmetic formulations it is used as a surfactant and emulsifier; when neutralized with an alkali it forms a soap that contributes cleansing and foaming. It also serves as a structuring and emulsion-stabilizing component in creams and sun care products.
Safety & warnings
Lauric acid is well established in cosmetic use, primarily within rinse-off cleansers and as a minor structuring component in leave-on products. As a fatty acid associated with coconut oil, it is regarded as having comedogenic potential and may contribute to clogged pores in acne-prone individuals when present at higher levels. In neutralized soap systems it is generally low-residue.
Origin & sourcing
Most commonly derived from natural sources such as coconut or palm kernel oil, though it can also be produced synthetically. It is one of the principal fatty acids of coconut oil.
Questions everyone asks
What does lauric acid do in a formula?
It acts as a fatty-acid surfactant and emulsifier, contributing to cleansing and to the structure and stability of emulsions.
Can lauric acid clog pores?
It is considered to have comedogenic potential, so acne-prone users may prefer to monitor leave-on products containing it at higher levels.
