Description

DETAILED DESCRIPTION OF THE INVENTION

(1) Described herein is a reconstitutable surfactant-based powder product which has good solubility in water and forms a stable gel when dispersed in water.

(2) The reconstitutable surfactant-based powder of the invention is a dry mixture of surfactants that provide cleansing. Said Reconstitutable powder consists of a polymer/gum system conferring gelling and stability to the formulation upon reconstitution. The reconstitutable surfactant-based powder may also contain effective amounts of stabilizers and buffers, appropriate natural or artificial conditioning agents, natural ingredients like Aloe Vera and Neem, fragrances, and colours.

(3) In an embodiment, the reconstitutable powder of the invention comprise of a 12-22% polymer/gum system conferring gelling and stability to the formulation upon reconstitution, 0.001 to 10% by weight one or more dry powder extracts, 5-95% by weight surfactants and co-surfactants, 2-30% by weight one or more thickening and stabilizing agents, 0-5% by weight of water. The powder formulation further comprises 0.3 to 2% by weight chelating agent, buffering agents and 0.4 to 3% by weight preservatives. Preferably, dry powder extracts of Aloe Vera and Neem are coated/adsorbed on Silica to provide the reconstitutable powder of the invention with 0.2 to 1.0% by weight fragrance and impart conditioning and germ washing property the formulation. In an Optional embodiment, the powder formulation may further comprise, conditioning agents, herbal extracts, fragrance, colour, and anticaking agents.

(4) In accordance with above embodiment, the polymer/gum system may be selected from, but not limited to, Cellulose, Gaur Gum, xanthan gum, trimethyl cellulose (TMC), Hydroxypropyl methylcellulose (HPMC), Carboxymethyl Cellulose (CMC), or combinations thereof.

(5) In accordance with above embodiment, the chelating agent could be selected from EDTA, Disodium EDTA, Nitrilotriacetic acid, or combinations thereof.

(6) The powder formulation can be used directly or with water preferably after reconstitution, to prepare cleansing products such as shampoo, body wash, hand wash and household cleaning products.

(7) In an embodiment, the powder sachet is provided with an empty pump bottle. The empty bottle is filled with water up to a recommended level, into which the sachet is to be emptied. The, hence, filled bottle is shaken for 2-3 min to disperse the powder well. It takes approximately two (2) hours to get a good gel that can be easily pumped out of bottle. Accordingly, the 9 gms to 10 gms of the reconstitutable powder of the invention is mixed in 200 ml water.

(8) In an embodiment, the invention provides a kit for cleansing. The kit contains a sachet containing the reconstitutable powder and container for reconstituting the reconstitutable powder and dispensing reconstituted gel. Preferably, the container for reconstituting the reconstitutable powder and dispensing reconstituted gel is a pump bottle made up of a transparent material. Said container could be demarcated to indicate specific volume, preferably 200 ml.
