SODIUM C12-13 ALKETH SULFATE: what it is

Sodium C12-13 Alketh Sulfate is a cleansing ingredient made from the sodium salt of a sulfated polyethylene glycol ether. The C12-13 portion refers to a mixture of synthetic fatty chains containing 12 and 13 carbon atoms, combined with an ethoxylated portion and then sulfated.

Older references may call it Sodium C12-13 Pareth Sulfate. That naming change matters when comparing labels, ingredient lists, or product information: it identifies the same cleansing ingredient, rather than two different skin-care actives.

SODIUM C12-13 ALKETH SULFATE: what it does in cosmetics

In rinse-off products, Sodium C12-13 Alketh Sulfate helps water spread over oil, sweat, and residue so they can be lifted away during washing. For a shopper, that usually means it contributes to the cleansing action of products such as liquid soaps, body washes, and similar wash products.

Its primary job is cleansing; seeing the name on a label does not mean a product treats acne, dark spots, or other skin conditions. The published Cosmetic Ingredient Review assessment considered the ingredient for cosmetic uses and concentrations in practice at the time, not as evidence of a clinical benefit for the person using the product.
