The BASF Group has presented new research findings from its Care Chemicals division on the development of innovative and sustainable cosmetic ingredients. BASF researchers presented new insights into the role and spread of corynebacteria in skin ageing, as they occur more frequently in older skin. The results show that these bacteria, which occur naturally on the skin, are a promising approach to anti-ageing skin care. Tests with rinse-off and leave-on formulations showed that they preserve the healthy skin microbiome without compromising on moisture-binding, mild or sensory properties.

The power of taurine

With these findings, BASF is placing greater emphasis on a holistic approach to microbiome-friendly cosmetics. The team also identified an encapsulation solution that can increase taurine and TauT levels and open up new avenues for anti-ageing care. A joint study with Stanford University also demonstrated that bio-based polysaccharides in cosmetic formulations increase skin moisture, improve product stability and enhance the penetration of moisturisers into the skin.

Greater stability for retinol

Another focus at BASF is on developing more stable vitamin A products. Retinol was combined with solid lipid particles, resulting in significantly higher stability: after four months, 83 per cent of the active ingredient was still present – unlike in conventional formulations. In addition, a 43 per cent increase in collagen I production was demonstrated. BASF's Care Chemicals division offers numerous ingredients for personal care. With these innovations, the German company aims to underline its commitment to providing high-performance, sustainable ingredients for cosmetic brands.
