DIPALMITOYL CYSTINE.

Insufficient Data CAS 17627-10-0 / ANTISTATIC, HAIR CONDITIONING

Dipalmitoyl Cystine is a fatty acid derivative of the amino acid cystine, primarily recognized for its antistatic and hair conditioning properties. While commonly utilized in hair care to enhance combability, softness, and shine, its direct efficacy and precise mechanisms for skin benefits are not detailed in current research data.

Summary

Antistatic

Science

Mechanism of Action

Derived from the acylation of cystine with palmitoyl chloride, Dipalmitoyl Cystine functions by significantly reducing electrostatic charges, particularly on hair, thereby acting as an effective antistatic agent. As a hair conditioning agent, it contributes to improved hair texture, rendering it supple, soft, shiny, and easier to manage. Specific mechanisms regarding direct interaction or benefits for skin are not provided in the available data.
