The water-soluble polymer that can reach required product thickening property in surfactant system is known, in addition, can improve its thickening usefulness to the hydrophobically modified of water-soluble polymer.But it is also known in undiluted water soluble surfactant active's system, the thickening property of the water-soluble polymer that these are hydrophobically modified can significantly reduce (as what discuss in Sau and Landoll work " polymer in the water-bearing media ", referring to " chemical progress ", No. 223, the 8th, 17,18 chapters, J.E.Glass compiles).The applicant finds that especially hydrophobically modified polymer (as hydrophobically modified hydroxyethyl-cellulose) can not make product have good thickening in undiluted water soluble surfactant active's system.Here " undiluted " of Xian Dinging is meant and contains approximately in the surfactant system greater than 1% heavy water soluble surfactant active.Here " water solublity " of Xian Dinging is meant that the molecular weight of surfactant is less than about 20000, and wherein surfactant can form clarifying, isotropic solution with 0.2% (weight) when soluble in water under room temperature (25 ℃).
The effective thickened systems that therefore need be used for undiluted water soluble surfactant active's system, this system should be able to make product have good product thickening property and rheological properties in storage, distribution and use, have fabulous product attribute such as foaminess, spatter property, rinsing, skin mildness with seasonal product, and fabulous skin usability.
Be surprised to find that at present under storage and service condition and had fabulous product thickening property and rheological properties personal cleaning compositions, wherein obtain, mainly contain the polymer and the polar oil of associativity in this thickened systems by thickened systems being added in undiluted water soluble surfactant active's system.Find in addition to be used in the thickened systems of the present invention of surface activator composition, the consumption of the thickening agent of using before the total amount of the thickening agent that adopts is starkly lower than just can reach required thickening effect.
The applicant finds that also thickened systems of the present invention is applicable to water soluble nonionic surfactant (as the polyhydroxy fatty acid amide surfactants) thickening that makes gentleness.
