New encapsulation for retinol
BASF launches VitaGuard A, a gentler anti-aging technology
BASF has developed "VitaGuard A", a new active ingredient designed to meet the high demand for retinol and strengthen its position as a key ingredient in cosmetics. The innovation is based on the idea of encapsulating free retinol, a highly effective variant of vitamin A. It serves as a powerful anti-ageing molecule and is widely used in cosmetics, but can cause skin irritation. It is also susceptible to degradation by light and air, which makes it difficult to use in cosmetics. BASF's Care Chemicals division is countering these disadvantages with the new formulation.
Protection against skin irritation
BASF's patented solid lipid encapsulation technology was used to stabilise retinol in cosmetic formulations. VitaGuard A was developed using solid, water-insoluble lipid particles that protect retinol from degradation. Compared to non-encapsulated retinol this would limit skin irritation, enable better bioavailability and improve cosmetic efficacy. In this way, forehead wrinkles would be reduced and skin elasticity and evenness of skin tone improved. This has been confirmed by several in-vitro and ex-vivo studies for BASF, the company announced.
Clinical study shows effectiveness
Among other things, a randomised full-face double-blind study with Chinese consumers showed that the volume of forehead wrinkles was reduced by 37 percent after eight weeks. Skin elasticity increased by 16 per cent. "The development of VitaGuard A underlines BASF's commitment to fulfil customers' needs for easy application of retinol and to achieve a remarkable anti-ageing effect," reports the company. At the same time, it illustrates how BASF's personal care business is responding to challenges such as sustainability, digitalisation and innovative collaboration models.
