Compositions de nettoyage stables contenant un agent blanchissant et des abrasifs doux

Stable bleach-containing cleansing compositions with soft abrasives

Abstract

A hard surface scouring cleaner composition comprises, by weight, (a) from 0.5 to 10 % of soft abrasive particles, (b) from 0.5 to 2.5 % of a chlorine-containing bleach, (c) from 0.2 to 3.0 % of a thickening system comprising from 0.2 to 3.0 %, based on the weight of the composition, of a cross-linked polyacrylate resin having a molecular weight in the range of 1,000,000 to 10,000,000 and from 0 to 2.5 % of a synthetic smectite clay, (d) from 0.25 to 3.0 % of a bleach-stable surfactant system comprising mainly anionic surfactants, (e) from 0 to 3.0 % of an electrolyte selected from the group comprising sodium or potassium carbonates or silicates, and (f) sufficient amount of sodium or potassium hydroxide to provide a pH in the range of 11.5 to 13.5. These compositions have an apparent viscosity as measured on a Brookfield RVTDV-II with a #6 spindle at 50 rpm of from 0.5 to 7 Kcps and at 1 rpm of from 10 to 150 Kcps. The abrasive particles are preferably organic particles such as polyethylene or polypropylene.
