The Sun Care industry, in particular, is under pressure to develop ocean-friendly formulations. Covestro has developed a holistic approach to its sustainability program that addresses the entire value chain from raw materials to the end of life. For sun care formulations, Covestro offers an eco-friendly film former, Polyurethane-34 (Baycusan® C 1000), that is suitable for formulating environmentally safe and sustainable products with high performance. In this paper, results of the biodegradability study and the advantages of Polyurethane-34 in sun care formulations will be discussed. An approach to develop environmentally friendly sun care products based on selected organic UV-filters will be proposed. An effective sun protection formula was developed. This formula exhibits a high SPF value, is water resistant and offers a lightweight feel on skin. Most importantly, these formulations are ocean-friendly and compliant with global regulations.

Long-term and comfortable sun protection / Yuliya Berezkin in PERSONAL CARE EUROPE, Vol. 12, N° 1 (02/2018)  

[article]  inPERSONAL CARE EUROPE > Vol. 12, N° 1 (02/2018) . - p. 63-65 Titre : Long-term and comfortable sun protection Type de document : texte imprimé Auteurs : Yuliya Berezkin, Auteur ; Astrid Wulfinghoff, Auteur ; Sophie Viala, Auteur Année de publication : 2018 Article en page(s) : p. 63-65 Langues : Anglais (eng) Catégories : Cosmétiques Facteur de protection solaire Peau -- Soins et hygiène Produits antisolaires Résistance à l'eau salée Résistance à la transpiration Résistance au sable Index. décimale : 668.5 Parfums et cosmétiques Résumé : Consumers have high expectation towards sun care which is used for face, sports and kid-friendly products. There are a wide range of requirements, but all need to perform the vital aspect of protecting the potentially very dangerous effects of overexposure to UV rays. One of the key issues within the sun care industry is ensuring products are properly applied and re-applied regularly. In order for this to happen they need to be pleasant to use and apply, while also being resistant to the type of conditions frequently encountered in beach environments. Contact with sand, sweating and humidity are challenging for a sun protection formulation and can significantly affect the effectiveness of the protection. Baycusan film-formers when introduced to sun care formulations can help alleviate these issues and contribute to achieving sand-resistant, sweat-and humidity-resistant claims.
