| Résumé : |
Consumers expect from their sunscreen products not only highly effective protection from UV rays, optimal water resistance, formulation stability and at the same time a light and dry skin feel. The rising environmental awareness also leads to a higher demand for responsibly sourced and sustainable ingredients.
The formulator's dilemma is to find sustainably sourced alternatives to ingredients that are under scrutiny such as SPF-boosters, film formers and other typically synthetic or silicone-derived raw materials used in sunscreens – without compromise in the formulation performance, stability and skin feel.
Here we describe a multifunctional blend that is unique in its natural and holistic approach to the multiple challenges of formulating modern sunscreen products. It can effectively enhance the efficiency of the used UV-filters, improve the water resistance and formulation stability, and has a beneficial impact on the skin feel of the emulsions. Based on responsibly sourced raw materials, it is the next step towards a higher degree of sustainability and naturalness in sun protection cosmetics. |
