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.

First claim

The invention claimed is:

1. A method of cleansing a keratinous substrate, the method comprising:
applying a granulated dry composition having granules to the keratinous substrate; and
removing the granulated dry composition from the keratinous substrate;
wherein the granules are agglomerated particles having a non-elastomeric polyorganosiloxane in liquid form agglomerated with a solid particulate carrier,
wherein the solid particulate carrier is capable of absorbing body fluids,
wherein the mean particle diameter of the granules is 0.02 to 1.5 mm, and
wherein the weight ratio of the non-elastomeric polyorganosiloxane to the solid particulate carrier is in the range of 2:98 to 80:20, wherein the non-elastomeric polyorganosiloxane is amodimethicone.

2. The method according to claim 1 , wherein the granulated dry composition is applied to the keratinous substrate by sprinkling or spraying or with an applicator.

3. The method according to claim 1 , wherein the keratinous substrate is hair.

4. The method according to claim 1 , 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.

5. A method of cleansing a keratinous substrate in the absence of water, the method comprising:
applying a granulated dry composition having granules to the keratinous substrate; and
removing the granulated dry composition from the keratinous substrate;
wherein the granules are agglomerated particles having a non-elastomeric polyorganosiloxane in liquid form agglomeratedonte with a solid particulate carrier,
wherein the solid particulate carrier is capable of absorbing body fluids,
wherein the mean particle diameter of the granules is 0.02 to 1.5 mm,
wherein the weight ratio of the non-elastomeric polyorganosiloxane to the solid particulate carrier is in the range of 2:98 to 80:20, and
wherein the non-elastomeric polyorganosiloxane is amodimethicone.

6. The method according to claim 1 , wherein the granules are formed by contacting the solid particulate carrier with an emulsion comprising the non-elastomeric polyorganosiloxane under conditions such that the non-elastomeric polyorganosiloxane in liquid form is agglomerated with the solid particulate carrier.

7. The method according to claim 1 , wherein the composition comprises at least 80 wt % of the solid particulate carrier and the non-elastomeric polyorganosiloxane.

8. The method according to claim 5 , wherein the granules are formed by contacting the solid particulate carrier with an emulsion comprising the non-elastomeric polyorganosiloxane under conditions such that the non-elastomeric polyorganosiloxane in liquid form is agglomerated with the solid particulate carrier.

9. The method according to claim 5 , wherein the composition comprises at least 80 wt % of the solid particulate carrier and the non-elastomeric polyorganosiloxane.
