Description

Conditioning Shampoo Composition Improved in Stability

The present invention relates to a conditioning shampoo composition with improved stability. More specifically, in a shampoo composition composed of at least one surfactant, cationic polymer, pearl composition for appearance and stabilization, the conditioning shampoo composition which essentially contains at least one polyester crosslinked polymer to improve stability over time It is about.

In detergents or cosmetic compositions, pearls are used to impart a brilliant pearly appearance and to maintain the dispersed water-insoluble conditioning agent in the product for a long time. Known pearls include mono- or di-esters of ethylene glycol, propylene glycol, oligomeric alkylene glycols and the like. Pearls in the solid state at room temperature are melted to a high temperature state and then crystallized to have pearly luster and pearly feeling.

Conventionally, a pearl composition prepared using a common composition including a pulping agent, a dispersing agent, and a pearl adjuvant and a general cooling method and mixed into a product separately has been used as a shampoo composition (US Patent Application No. 5,925,604, US Patent Application 6,165,955), the use of a small amount of the pearl composition in the shampoo composition had a disadvantage in that the stability of the product was deteriorated, the product stability is improved in the case of a large amount of use, but due to the rough feeling of the pulping agent, the soft texture is reduced during rinsing and a smooth texture when wet There was a disadvantage that the hair is rough in the dry state falling.

The present invention is provided to more efficiently solve the problems of the prior art as described above, the object of the present invention is to a shampoo composition comprising a conventional pearl composition comprising anionic surfactant, nonionic surfactant, pulping agent It is to provide a shampoo composition which improves stability and improves the conditioning effect even with a small amount of a conventional pearl composition using at least one polyester crosslinked polymer.

The above and other objects of the present invention can be achieved by the present invention described below.

Conditioning shampoo composition with improved stability according to the present invention is a shampoo composition containing anionic surfactant, nonionic surfactant, pulping agent and silicone, 0.01 to 20% by weight of the total weight of the polyester crosslinked polymer of the formula (1) Contains weight percent.
