BASF’s personal care business is introducing a new ingredient, VitaGuard A, to address continued market demand for retinol while strengthening its position as a hero ingredient in cosmetics. This latest innovation is based on the encapsulation of free retinol.

Retinol is a powerful anti-aging molecule widely used in cosmetic applications. However, it can also cause skin irritation and is prone to light and air degradation, making it difficult to use on a large scale by formulators. VitaGuard A was formulated using patented solid lipid particles, protecting retinol from degradation, limiting skin irritation and allowing better skin bioavailability for improved cosmetic efficacy.

Several in vitro and ex vivo studies conducted by BASF have shown VitaGuardĀ® A to improve retinol stability in cosmetic formulations, increase skin bioavailability and reduce retinol-induced irritation compared to unencapsulated retinol. has been shown to prevent Additionally, it clinically improves the appearance of forehead wrinkles, skin elasticity and evenness of skin tone to match the attractive nature of retinol as an anti-aging molecule.
