Granulated dry cleanser for the care of keratinous substrates

Abstract

Described herein is a granulated dry composition comprising at least one non-elastomeric polyorganosiloxane, agglomerated onto solid carrier particles. The granulated dry compositions can be used as a dry cleanser for keratinous substrates with high speed of absorption of body fluids together with improved sensory feel and release of care agents.

1 . A granulated dry composition having granules, wherein the granules are agglomerated particles having a non-elastomeric polyorganosiloxane in liquid form agglomerated with a solid particulate carrier, and wherein the solid particulate carrier is capable of absorbing body fluids. 
     
     
         2 . The granulated dry composition according to  claim 1 , wherein the granulated dry composition comprises at least 80 wt % of the solid particulate carrier and the non-elastomeric polyorganosiloxane. 
     
     
         3 . The granulated dry composition according to  claim 1 , further comprising a binder and/or an additive substance selected from perfumes, fragrances, colorants, essential oils, deposition agents, buffering agents, stabilizers, proteins, preservatives, anti-dandruff agents, disinfectants, glycols, polyols, vitamins and/or their derivatives, styling agents, sunscreen agents, humectants, oil components, emollients, esters, ceramides, soothing ingredients, antiperspirants, malodor sequestrants, surfactants, amino-acid derivatives, antioxidants, botanicals, antimicrobial agents, conditioners, and silicone elastomers. 
     
     
         4 . (canceled) 
     
     
         5 . The granulated dry composition according to  claim 1 , wherein the solid particulate carrier comprises zeolite, aluminosilicates, silicates, mica, bentonite, diatomite, sepiolite, natural or modified clays, talc, neat or treated silica, cellulose and its derivatives, alginates, chitin, chitosan, starch and its derivatives, sulphate salt, wood flour or carbohydrates, or mixtures thereof. 
     
     
         6 . The granulated dry composition according to  claim 1 , wherein the mean particle diameter of the granules is 0.02 to 1.5 mm. 
     
     
         7 . The granulated dry composition according to  claim 1 , wherein the weight ratio of the non-elastomeric polyorganosiloxane to the solid particulate carrier is in the range of 2:98 to 80:20. 
     
     
         8 . The granulated dry composition according to  claim 1 , wherein the non-elastomeric polyorganosiloxane is an organomodified polysiloxane. 
     
     
         9 . The granulated dry composition according to  claim 1 , wherein the non-elastomeric polyorganosiloxane is an aminofunctional polyorganosiloxane. 
     
     
         10 . A method for preparing the granulated dry composition according to  claim 1 , the method comprising:
 contacting a liquid composition comprising the non-elastomeric polyorganosiloxane with the solid particulate carrier;   wherein the contacting is under conditions such that the liquid composition is agglomerated with the solid particulate carrier to produce an agglomerated product; and   wherein the agglomerated product is kept in granule form during agglomeration or is subsequently formed into granules.   
     
     
         11 . (canceled) 
     
     
         12 . The method according to  claim 10 , wherein the contacting is performed in a mixer, and the mean particle diameter of the solid particulate carrier fed to the mixer is between 1 micrometer and 250 micrometers. 
     
     
         13 . The method according to  claim 10 , wherein the liquid composition is sprayed onto the solid particulate carrier. 
     
     
         14 . The method according to  claim 10 , wherein the non-elastomeric polyorganosiloxane is an organomodified polysiloxane, alternatively is an aminofunctional polyorganosiloxane. 
     
     
         15 . (canceled) 
     
     
         16 . The method according to  claim 10 , wherein the liquid composition is in the form of an emulsion. 
     
     
         17 . A method of cleansing a keratinous substrate, the method comprising:
 applying a granulated dry composition to the keratinous substrate; and   removing the granulated dry composition from the keratinous substrate;   wherein the granulated dry composition is according to  claim 1 .   
     
     
         18 . The method according to  claim 17 , wherein the granulated dry composition is applied to the keratinous substrate by sprinkling or by spraying or with an applicator. 
     
     
         19 . (canceled) 
     
     
         20 . The method according to  claim 17 , wherein the keratinous substrate is hair. 
     
     
         21 . The method according to  claim 17 , wherein the granules further comprise an additive substance and the additive substance is deposited on the keratinous substrate by application of the granulated dry composition.
