Titre : Optical rejuvenating makeup using an innovative shape-controlled hybrid powder Type de document : texte imprimé Auteurs : Katsuhiko Yagi, Auteur ; Katsuki Ogawa, Auteur ; Tetsuya Kanemaru, Auteur ; Kyoko Joichi, Auteur ; Naomi Kunizawa, Auteur ; Ruriko Takano, Auteur Année de publication : 2006 Article en page(s) : p. 109-114 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Optical rejuvenating makeup' ' Hybrid powder' 'Red interference light' 'Reflecting plate' 'Skin tension' Sagging 'Platy barium sulfate' tension angle' Index. décimale : 668.5 Parfums et cosmétiques Résumé : For women, the sagging of facial skin noticed with ageing is one of the important problems that should be solved. Although conventional skincare cosmetics exist that can prevent sagging, no makeup cosmetics that can correct the appearance of sagging have been developed. The vital factors for an optical rejuvenating makeup were found to be recovery of the skin tension and lightening of the face shadow appearing on sagging skin. Therefore, a hybrid powder consisting of platy barium sulphate on the surface of titanium dioxide-coated mica having red interference light was developed. Results of a panel test showed that almost all panelists noticed the rejuvenating effect of the foundation containing the powder. Image analysis showed that the foundation finish made the face look 12 years younger than the face with no makeup. As the mechanism of the optical rejuvenation, regular reflection of the red interference light from the hybrid powder can give the natural-fresh impression observed for a very young skin, and diffuse reflection of the white light can irradiate the shadow. The development of this innovative shape-controlled hybrid powder offers a new technique for making anti-aging cosmetics.

Titre : Specialty inorganic thickeners & new generation opacifiers Type de document : texte imprimé Auteurs : Anil Bansal, Auteur ; K. K. Mishra, Auteur Année de publication : 2009 Article en page(s) : p. 121-130 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Inorganic clay Bentonite Thickeners Opacifier Aluminum silicate Synthetic barium sulphate White pigment Index. décimale : 667.9 Revêtements et enduits Résumé : The clays minerals, generally characterized by their small particle size, affinity for water, and response to chemical changes in their environment, are noted for their gelling and viscosity-increasing abilities in aqueous systems. Rendered organophilic by association with long-chain organic compounds, several of the clay minerals exhibit similar or even greater gelling abilities in various organic liquids.
Rheological or flow properties have important implications in many and diverse applications. Often, an additive is used to impart the desired flow behavior. Among these, organo clay products, formed by the reaction of organic cations with inorganic clays, are the most widely used additives for solvent-based coatings.
Titanium dioxide is multifaceted material in coating applications. It efficiency scatters visible light thereby imparting whiteness, brightness and opacity to paint and coating material. The cost of TiO2 is increasing steadily and thus the cost of paint with minimum operational margin. There are two ways to stabilize this rise in cost, one is to lower the quality of paint by less use of essential ingredients and another way is to use the subsidiary product in the replacement of the primary product either cent percent replacement or partial replacement which gives some cost advantages.
This work is related to partially replacement of organic thickener by hydrogel 70T, bentocol and rheo-bentone and TiO2 pigment with lithomer R-A whitepigment opacifier or basofix - A synthetic barium sulphate or ALSIL ZX - A synthetic aluminium silicate in non aqueous and aqueous paints respectively, without effect on the quality of paint. The cent percent replacement of TiO2 is impossible and an attempt is made to replace it partially with cost benefit without affecting whiteness, brightness and opacity of paint. Both the extender pigments showed potential of replacing TiO2 in different type of coatings ranging from 15% to 25% by weight depending on the desired end properties.
The present study is focused on the use of inorganic clays as specialty inorganic thickeners and synthetic inorganic chemicals as new generation opacifier for weter and solvent borne paints and coatings. These are superior, particularly in terms of use, while providing the same excellent gelling, rheological, brightness & opacifier control offered by earlier additives.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=6909
