It is the presence of these groups that makes a molecule surface active. Surface active materials are important because they alter surface tension, which is a required first step in providing wetting, spreading, emulsification, detergency and cosmetic aesthetics. The use of surfactants in aqueous formulation is the best known example of surfactant usage. The less appreciated use of surfactants is the modification of oils to lower surface tension, resulting in improved spreading, wetting and gelation. The use of correctly selected amphiphilic silicone molecules allows one to replace traditional silicone compounds, including D5 and fluids, with natural oils, esters and other products having a greener profile. This process has been referred to as “greening with silicone”.

Structured gels with organic oils and alkyl dimethicone / Tony O'Lenick in PERSONAL CARE EUROPE, Vol. 12, N° 5 (11/2018)  

[article]  inPERSONAL CARE EUROPE > Vol. 12, N° 5 (11/2018) . - p. 74-76 Titre : Structured gels with organic oils and alkyl dimethicone Type de document : texte imprimé Auteurs : Tony O'Lenick, Auteur ; David Zhang, Auteur Année de publication : 2018 Article en page(s) : p. 74-76 Note générale : Bibliogr.

Butters are divided into two classes, those that exist in nature, including shea butter,' cocoa butter, mango butter, lilpe butter and several others or those that are man-made such as olive butter. Butters are structured gels that provide not only a unique skin-feel but also have a great rheology thinning under pressure. There are only a handful of butters in nature, many of the rest are made by partial hydrogenation of the oil. Another approach to make structured gels that avoid partial hydrogenation is addition of alkyl dimethicone compounds to natural oils and esters. These compositions offer the formulator the ability to make a wide variety of structured oil formulations offering a variety that of formulations that not only have a great initial feel and playtime on the skin, but a variety of tunable final aesthetics after rub in. This article will address the basic technology used to make these materials.
