Claims20
A pearlescent liquid detergent composition having a turbidity less than 3000 NTU comprising:
- greater than about 5% of an anionic surfactant, less than about 25% of a nonionic surfactant, a light-sensitive ingredient, a perfume microcapsule comprising a capsule made of materials selected from the group consisting of urea and formaldehyde, melamine and formaldehyde, phenol and formaldehyde, gelatine, polyurethane, polyamides, cellulose ethers, cellulose esters, polymethacrylate, and mixtures thereof, a pearlescent agent comprising an organic pearlescent agent having a refractive index more than about 1.41 and an inorganic pearlescent agent having a refractive index more than about 1.41, wherein the difference between refractive indices of said organic and inorganic pearlescent agents and said composition is at least about 0.02 and from 1% to 5% of a co-crystallizing agent.
A method of improving the stability of light-sensitive ingredients in a pearlescent liquid detergent composition having a turbidity less than 3000 NTU comprising the step of adding a pearlescent agent comprising an organic pearlescent agent having a refractive index more than about 1.41, and an inorganic pearlescent agent, having a refractive index more than about 1.4.1, wherein the difference between refractive indices Of said organic and inorganic pearlescent agents and said composition is at least about 0.02, and from 1% to 5% era co-crystallizing agent to the liquid detergent composition.
