Abstract:
A aqueous liquid bleaching composition comprising:a) from 0.0% to 20% by weight, of a peroxygen bleach; b) from 0.001% to 20% by weight, of a zwitterionic betaine surfactant and from 0.001% to 30% by weight, of an ethoxylated nonionic surfactant; c) from 0.001% to 20% by weight, of a viscosity controlling agent selected from the group consisting of i. C3-C6 alkyl ammonium salts; ii. a glycol having the formula R1â€”Oâ€”(CxH2x)nâ€”R2, wherein R1 is C1-C5 saturated or unsaturated, substituted or unsubstituted alkyl; R2 is hydrogen, C1-C5 saturated or unsaturated, substituted or unsubstituted alkyl, and mixtures thereof, x has a value from 2 to 4; n has a value from 1 to 5; iii. an alcohol having the formula Raâ€”OH wherein Ra is C3-C8 saturated or unsaturated, substituted or unsubstituted alkyl; iv. an alcohol having the formula Rbâ€”OH wherein Rb is C5-C15 alkyl substituted or non-alkyl substituted aryl; and v. mixtures thereof; and d) the balance carrier and adjunct ingredients; wherein said composition has a viscosity of from cps to 100 cps when measured with a Brookfield viscometer with spindle 2, at 30 rpm and 20Â° C.
