This interest includes not only making more efficient formulations but also more effective formulations. There are many factors that need to be considered when determining the efficiency of sunscreen formulations, including : desired SPF, UVA/UVB coverage, wavelength shift, and photostability, just to name a few. The quest for complete protection from the sun has led to numerous research efforts that are aimed not only effective sunscreens, but also products that efficiently use sunscreens, minimising the concentration of filters. A product that protects over a wide variety of ultraviolet (UV) spectrum and is effective has become a priority. This quest has led to a new series of amphiphilic polymers that have been developed to help improve the efficiency of sunscreens. These amphiphilic polymers have a polar core surrounded by a fatty oil soluble group. This series of polymers can provide not only a shift in wavelength, but also boost the SPF of the sunscreen formulation. These new polymers have been coinde 'Spider esters'.

Refractive index modification of silicone polymers / Thomas G. O'Lenick in PERSONAL CARE EUROPE, Vol. 5, N° 5 (11/2012)  

[article]  inPERSONAL CARE EUROPE > Vol. 5, N° 5 (11/2012) . - p. 59-61 Titre : Refractive index modification of silicone polymers Type de document : texte imprimé Auteurs : Thomas G. O'Lenick, Auteur ; Tony O'Lenick, Auteur Année de publication : 2012 Article en page(s) : p. 59-61 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cosmétiques Emulsions -- Emploi en cosmétologie Formulation (Génie chimique) Réfractométrie Silicones -- Emploi en cosmétologie Index. décimale : 668.5 Parfums et cosmétiques Résumé : Silicone compounds are becoming a commonly used raw material in many cosmetic products. They find applications where they provide properties that cannot be obtained from other less costly raw materials. One of the properties that cannot be obtained from other less costly raw materials. One of the properties that can be modified in this class of materials that is often overlooked is refractive index. Refractive index is important in making clear emulsions, used in cosmetic formulations.
