ANTIPERSPIRANT COMPOSITIONS
Clear solid suspension antiperspirant compositions comprise 0.5 to 50% by weight of a particulate antiperspirant active material of which less than 50% by weight of its particles are below 10mm diameter and a refractive index of from 1.49 to 1.57 at 22oC is suspended in a water-immiscible carrier li...

Zusammenfassung: | Clear solid suspension antiperspirant compositions comprise 0.5 to 50% by weight of a particulate antiperspirant active material of which less than 50% by weight of its particles are below 10mm diameter and a refractive index of from 1.49 to 1.57 at 22oC is suspended in a water-immiscible carrier liquid of which at least 50% by weight is selected from liquid non-volatile silicone oils and liquid alkyl-aryl esters and not more than 25% by weight of the carrier liquid comprises a volatile silicone oil. The carrier liquid and the antiperspirant have refractive indexes which differ by no more than 0.02 at 22oC and the structurant which solidifies the carrier liquid comprises a fibre-forming non-polymeric structurant, and preferably an N-acyl aminoacid amide such as GP1 and/or a cyclodipeptide such as a thymol derivative of (2S-cis)-(-)-5-benzyl-3,6-dioxo-2-piperazine acetic acid.
Composiciones antitranspirantes de suspension, solidas, claras, comprendiendo 0.5 a 50% en peso de un material activo antitranspirante particulado del cual menos de 50% en peso de sus particulas estan por debajo de un diametro de 10mm y un indice de refraccion desde 1.49 hasta 1.57 a 22¦C, es suspendido en un liquido portador inmiscible de agua del cual al menos 50% en peso es seleccionado de aceites de silicon no volatiles liquidos y alquil-aril esteres liquidos y no mas de 25% en peso del liquido portador, comprende aceite de silicon volatil. El liquido portador y el antitranspirante tienen indices de refraccion, los cuales difieren por no mas de 0.02 a 2¦C y el estructurante el cual solidifica el liquido portador comprende un estructurante no polimerico formador de fibras, y de preferencia una amida de N-acil aminoacido, tal como, GP1 y/o un ciclodipeptido, tal como un derivado de timol de acido (2S-cis)-(-)-5-bencil-3,6-dioxo-2-piperazin acetico. |
