Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composition having excellent pearlescent luster and good dispersion stability.

BACKGROUND ART Conventionally, cleaning agents such as shampoos, body shampoos, cleansing foams, and hair cosmetics such as hair rinses have often been given a burl luster for the purpose of doubling the pleasure of use.

So-called burl brighteners for imparting burl luster include crystals of behenic acid (JP-A-57-149212) and diester of dicarboxylic acid (JP-A-57-149212).
67510), linear alkanediol diesters (Japanese Unexamined Patent Publication No. 57-67511), etc., but the most commonly used are fatty acid glycol diesters.

) Many attempts have been made to obtain good pearlescent luster using Ill fatty acid glycol diesters. For example, in JP-A-57-51799, a fatty acid glycol diester is used in combination with a nucleating agent such as sodium sulfate, ammonium chloride, citric acid, etc. to create a surfactant 1P agent composition for shampoos, conditioners, etc., which provides good pearl luster. JP-A-57-133400 discloses an attempt to obtain a more beautiful pearlescent luster by using an asymmetric fatty acid diester to account for 50% by weight or more of the fatty acid glycol diester.

Needless to say, when trying to obtain good pearlescent luster, it is desirable that the crystals formed by the pearlescent agent in the system have uniform particle sizes, smooth crystal surfaces, and as flat a particle shape as possible. . However, the inventors of the present invention attempted to produce shampoos and the like based on the above-mentioned publication, and the results were still unsatisfactory in terms of particle size uniformity, surface smoothness, particle shape flatness, etc.

In view of the above circumstances, the present inventors conducted extensive research to obtain a composition with more beautiful pearlescent luster, and found that if a specific polyether compound was blended in addition to a surfactant and a fatty acid glycol diester, It is possible to obtain crystals of fatty acid glycol diester having a uniform particle size, a smooth surface, and a flat particle shape, thereby obtaining a composition with a beautiful pearlescent luster that has not been achieved hitherto. It has been found that the pearlescent composition thus obtained has superior dispersion stability over time compared to a composition that does not contain the above-mentioned specific polyether compound. The present invention is based on the above findings.

That is, the present invention is a pearlescent composition characterized by containing the following four components.

(1) Surfactant (2) One or more fatty acid glycol diesters represented by formula (I) RCOO(CI-TzCI-12-0)ncOR" (

Naturally, when making the above-mentioned cleaning materials and hair cosmetics, it is necessary to select and use an appropriate surfactant from among the surfactants listed above. Note that if the surfactant content is less than 0.5% by weight, the detergency and rinsing effect of the pearlescent composition will be insufficient, and the above-mentioned fat, r! On the contrary, the dispersion of I glycol diester in system 1 becomes worse,
If the amount exceeds 35% by weight, the composition having burl luster tends to be more irritating to the eyes and skin, which is not preferable.

The fatty acid glycol diester used in the present invention is expressed by the following formula (1).

RC00(Cl+IC1r2-0) n COR'
(T) In formula (1), R and R' are each an alkyl group having 13 to 21 carbon atoms, and R and R' may be the same or different. The Azu paddle group may be a straight chain or a branched chain, but a 1lIJ chain is preferable because it provides better burl luster.
