Antistatic Hair Conditioning Skin Conditioning Cleansing Surfactant

Science

Mechanism of Action

On the skin, this ingredient operates as a conditioning agent and humectant, effectively drawing moisture into the skin and helping to retain it. It can form a delicate, protective film on the skin's surface, which minimizes transepidermal water loss, resulting in a smoother, more supple complexion and contributing to the reinforcement of the skin's natural barrier function.

The CIR Expert Panel concluded that keratin-derived ingredients, including Hydrolyzed Keratin, are safe under current practices of use and concentration. Hydrolyzed Keratin has been confirmed non-irritating at 100% in in vitro studies and up to 25% in human studies. No sensitization was observed in guinea pig maximization studies at up to 25% or in Human Repeat Insult Patch Tests (HRIPTs) at up to 5%. It is important to note that the 25% maximum concentration refers to Hydrolyzed Keratin generally, not specifically Sodium Cocoyl Hydrolyzed Keratin. EWG Skin Deep rates 'Cocoyl Hydrolyzed Keratin' with low concern regarding cancer, allergies & immunotoxicity, developmental & reproductive toxicity, and use restrictions.
