Sodium PCA

* A humectant

Sodium PCA is a naturally occurring humectant found in human skin that is a derivative of amino acids. Sodium PCA is the salt of pyrrolidone carbonic acid. It has high water absorbing properties, and is also considered to be hygroscopic, with the ability to absorb moisture from the air (VitaminStuff.com and other research). It can also bind moisture to cells, and hold several times its weight in water. It delivers moisture to the hair and skin, and is often seen as an emollient or humectant in hair conditioners and moisturizers; it is also seen as an ingredient in shampoos, hair sprays, permanent waves, skin fresheners and other hair and skin care products, according to RealSelf.com.

Sodium PCA is CIR approved with concentration limits to 4%.

Safety Measures/Side Effects:

The Cosmetics Database finds Sodium PCA to be a low hazard ingredient, and only notes concerns regarding the contamination of nitrosamine, a known toxin. According to the CIR Expert Panel on RealSelf.com, avoiding formulas that contain nitrosating agents should resolve any concerns regarding nitrosamine. "Sodium PCA was nonirritating to the eye and skin at concentrations up to 50%. No evidence of phototoxicity, sensitization or comedogenicity was found. These ingredients were not genotoxic. In a range of clinical tests, PCA and Sodium PCA were found to be nonirritating and nonsensitizing (with and without UV exposure)."
