[0078] In the preparation step of the siloxane used in the silicone composition, in the second step of the process of the invention, allyloxy (polyethylene oxide) (available under the Polymeg trademark from IGL, India).

[0079] Allyloxy (polyoxyethylene) or ethylenically unsaturated polyethers are preferably selected from polyethylene glycol allyl methyl ether CH 2 =CHCH 2 (OC 2 h 4 ) n OH; CH 2 =CHCH 2 (OC 3 h 6 ) n OH; polyalkylene glycol allyl methyl ether (EO / PO random) CH 2 =CHCH 2 O(C 2 h 4 O) l (C 3 h 6 O) k H, where l and k are an integer of 2 to 100, preferably 19 to 40, and more preferably 19 to 30. A non-limiting example of a preferred ethylenically unsaturated polyether is allyloxy(polyethylene oxide) (EO 25) available under the Polymeg trademark from IGL, India. The ethylenically unsaturated polyethers are used in an amount of 1 to 1.1 mol of ethylenically unsaturated groups (C=C) in the polyether per 1 mol of Si-bonded hydrogen in the hydrosilo...

Abstract

The invention to provide an foamable silicone composition, that would easily integrate or mix with the powder or liquid detergent composition having reduced active ingredient having enhanced or similar detergency effect i.e. foaming and dirt removal characteristics and having no negative effect on the detergency and the preferred foaming nature of the detergent during the washing cycle. The foamable silicone composition comprising a silicone composition comprising a siloxane comprising a polyoxyalkylene group having 19 to 30 oxyalkylene group, with the proviso that the siloxane contain at least one oxyalkylene radical per molecule.

Description

[0001] field of invention [0002] The present invention relates to a foamable silicone composition which can be easily integrated or mixed with a powder or liquid detergent composition having reduced active ingredients, said composition having enhanced or similar cleaning benefits, i.e. stable Sudsing, detergency properties, and no negative impact on detergency and preferably sudsing of the detergent during the wash cycle. [0003] In today's world, there are a large number of detergents used in millions of households all over the world, as well as in different industries. These detergents use high active detergents for good sudsing and cleaning. Anionic surfactants are the main components in detergents, and a larger amount of anionic surfactants enters the water system through rinse water. Larger amounts of detergents with anionic surfactants in the water system can upset the balance and create unfavorable conditions for aquatic organisms. Such entry into water bodies will ...
