Abstract

The invention relates to method of reducing viscosity of high active liquid concentrate cleanser by adding perfumes, individual perfume components, or mixtures of components.

Claims

1. A method of reducing viscosity of liquid composition comprisingby wt. or more of a surfactant selected from the group consisting of anionic, nonionic, amphoteric/zwitterionic, cationic surfactant and mixtures thereof;

substantially no perfume, and zero shear viscosity of 200-1000 Pa·

s to viscosity of 10 to 150 Pa·

s;

wherein said method comprises adding individual perfume component having molecular volume (V)>

400 A³ and polarity>

1 MPa¹¹² or adding mixture of components, wherein components having said volume and polarity values comprise >

50% of the perfume mixture.

2. A composition according to claim 1, comprising 0.1 to 65% viscosity or modulating agent.

3. A composition according to claim 1 comprising 0.1 to 1.5% by wt. cationic polymer and 0 to 3% by wt. solid particulate modifier.

4. A method according to claim 1 comprising 20 to 60% by wt. surfactant.

5. A method of reducing viscosity of liquid composition comprising 15% by wt. or more of a surfactant selected from the group consisting of anionic, nonionic, amphoteric/zwitterionic, cationic surfactant and mixtures thereof;
