HYDROXYSUCCINIMIDYL C21-22 ISOALKYL ACIDATE

Description

HYDROXYSUCCINIMIDYL C21-22 ISOALKYL ACIDATE is a specialized skincare ingredient that functions as a skin conditioning agent and emollient. This long-chain fatty acid derivative is engineered to enhance the penetration of active ingredients into the skin's deeper layers. Its unique molecular structure allows it to form a temporary bond with proteins in the skin, facilitating the delivery of other beneficial compounds.

The ingredient's hydrophobic tail helps it integrate seamlessly into the skin's lipid barrier, improving overall skin texture and hydration. Its ability to form a thin, protective film on the skin's surface contributes to reduced transepidermal water loss, promoting long-lasting moisturization.

In formulations, HYDROXYSUCCINIMIDYL C21-22 ISOALKYL ACIDATE can enhance the stability and efficacy of other active ingredients, particularly those that are typically challenging to deliver effectively. It is compatible with a wide range of cosmetic formulations, including serums, creams, and lotions.

While generally well-tolerated, as with any skincare ingredient, patch testing is recommended to ensure individual compatibility. Its use in products may be particularly beneficial for individuals with dry or mature skin seeking enhanced hydration and improved ingredient penetration.
