This allows silicone polymers to be added at less than 10% concentration and often less than 5% concentration and provide a different customer experience than achieved by standard silicones. Since the formulation is 90%-1- identical to the starting formulation, the time and work needed to evaluate change is minimised. Likewise the toxicology of the formulation, the need for many raw materials and the cost change is minimised. We have therefore called this approach Minimally Disruptive Formulation. This article will show the concept in a moisturising product. Note de contenu : - TABLES : 1. Differences between disruptive and sustaining formulating - 2. Initial formulation - 3.

Hydroalcoholic triglyceride emulsions investigated / Tony O'Lenick in PERSONAL CARE EUROPE, Vol. 8, N° 6 (11/2015)  

[article]  inPERSONAL CARE EUROPE > Vol. 8, N° 6 (11/2015) . - p. 51-53 Titre : Hydroalcoholic triglyceride emulsions investigated Type de document : texte imprimé Auteurs : Tony O'Lenick, Auteur ; David Zhang, Auteur Année de publication : 2015 Article en page(s) : p. 51-53 Langues : Anglais (eng) Catégories : Alcools Emulsifiants Emulsions -- Emploi en cosmétologie Emulsions -- Stabilité Formulation (Génie chimique) Silicones -- Emploi en cosmétologie Stabilisants (chimie) Triglycérides Index. décimale : 668.5 Parfums et cosmétiques Résumé : Emulsions are very important in preparation of a number of personal care formulations. Most emulsions contain a water phase and a water insoluble phase. Emulsions containing only these elements are difficult to make with the desired stability, functionality and aethetics. If one adds ethanol, a material that partitions between the water and oil phase, preparing suitable emulsions becomes much more difficult. This paper deals with a multi-stepped approach to making difficult emulsions, one type being emulsions that contain oil, water and alcohol. In the first step the proper HLB is determined experimentally, and in the second structural variables within a particular HLB are investigated. This combined approach provides very stable emulsions.

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. Langues : Anglais (eng) Catégories : Alkyl diméthicone Cosmétiques -- Texture Emulsions -- Emploi en cosmétologie Formulation (Génie chimique) Gels -- Emploi en cosmétologie Silicones -- Emploi en cosmétologie Index. décimale : 668.5 Parfums et cosmétiques Résumé : Butters are very commonly used in personal care formulations. 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.
