Coconut Acid
Explained
Coconut acid is a mixture of fatty acids obtains by hydrolyzing coconut oil and then distilling the fatty acid portion. It works as a cleansing surfactant, emollient, and emulsifier depending on the formulation.
This ingredient is not a single compound but reflects the fatty acid profile of coconut oil itself, which is about 90% saturated.
The dominant fatty acid is lauric acid (44-54%) and then myristic acid (13-19%). There are also small amounts of caprylic, capric, palmitic, oleic, and linoleic acids.
Human testing from CIR has shown no indication this ingredient to be a primary irritant, sensitizer, or phototoxic compound. It's COSMOS-approved for natural and organic products.
Due to the fatty acid content, this ingredient may not be fungal acne safe. Research has confirmed Malassezia can use lauric acid as a food source.
