Uses: Octyl glycol is mainly used in cosmetics as a skin conditioner, hair conditioner, moisturizer, and preservative. Octyl glycol belongs to the 1,2-glycol class of compounds used in cosmetics, which have skin and hair conditioning properties. It has a long history of use; according to a CIR report, the highest safe concentration of caprylyl glycol used in 1721 leave-on products was 5%, and there were no safety concerns with its current usage concentration formulations.

Caprylyl glycol is a multifunctional cosmetic ingredient whose main functions include:

* Moisturizing and Emollient: Caprylyl glycol has excellent hygroscopic properties, helping the skin absorb and retain moisture, keeping it hydrated and smooth. It also forms a protective film on the skin's surface, reducing moisture loss.

* Antiseptic and Antibacterial: It inhibits the growth of molds, yeasts, and various bacteria. It is often used in combination with other preservatives to enhance preservative effects and extend product shelf life.

* Texture Adjustment: As a viscosity modifier, caprylyl glycol can improve the fluidity and stability of products, making them easier to apply and resulting in a more even texture.

* Enhancing Other Ingredients: Caprylyl glycol can dissolve some poorly soluble preservatives, improving the stability and effectiveness of other ingredients in the product.

Caprylyl glycol is a safe and commonly used cosmetic ingredient suitable for various skin types, especially excelling in moisturizing and preservative properties.
