Also called intelligent protections, they offer many other advantages than just UV protection and are adapted to the consumers' urban, leisure and extreme lifestyle conditions. At the same time, the high SPF formulations bring new challenges in terms of product protection because of the high oil content of the formulations. Indeed, conventional preservatives are under constant scrutiny and formulators need to be increasingly creative by incorporating innovative product protection molecules in their formulations to limit the proliferation of microbial contaminants. Phenoxyethanol, benzyl alcohol, hydroxacetophenone, pentylene glycol and caprylyl glycol are some of the important ingredients in the toolbox for the formulators to support them for this purpose. Phenoxyethanol and benzyl alcohol are two commonly used preservatives in cosmetics. In sun care products, hydroxyacetophenone contributes to the antioxidant properties of the formulations and 1,2-alkanediols such as pentylene glycol and caprylyl glycol act as moisturizers while improving the aesthetics of the formulations. At the correct dosage, these versatile ingredients play a key rote in modern product protection. Note de contenu : - Table 1 : Molecules used for modern protection

Ressources renouvelablesIndex. décimale : 668.5 Parfums et cosmétiques 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.Note de contenu : - Fig. 1 : 360° approach - SynEffect TM sun
