2. Description of the Related Art Conventionally, an emulsifier for imparting an emulsified or pearl-like luster to the appearance for the purpose of enhancing the aesthetic appearance of a shampoo, body shampoo, facial cleanser, etc. which is washed away after application to the skin or hair. Alternatively, a pearlizing agent (hereinafter referred to as a pearlizing agent) is used. As pearling agents, etc.,
Fatty acid esters of glycols, for example, ethylene glycol distearate, are widely used. The following method is given as a method for imparting pearly luster.
Ethylene glycol distearate has a melting point of 60-65.
Since the temperature is ° C, the surfactant is heated to the above-mentioned melting point and melted in the manufacturing process of shampoo, body shampoo, face wash and the like. Thereafter, crystallization starts in the cooling step, and the product has a pearl-like luster. In addition, by preparing a concentrated product having a pearl-like luster (hereinafter, referred to as a concentrated pearling agent composition) in advance and adding it at a temperature equal to or lower than the melting point of the pearling agent at the time of blending the detergent composition, etc. A method capable of imparting uniform and constant pearl-like luster to each product in a short time is already known.

[0003] In any case, however, the pearly luster is easily affected by the stirring speed and cooling speed during cooling. For example, if the stirring speed or cooling speed is not appropriate, pearl-like luster cannot be obtained, or even if pearl-like luster is obtained, the crystals are not uniform and the pearl-like luster is inferior. In some cases, the gloss was not constant, and a long blending time was required.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a concentrated pearling agent composition capable of imparting a good pearl-like luster to a detergent composition or the like uniformly in a short time. It is to be.

That is,
The composition of the present invention has a pearl-like luster itself, and can provide a uniform pearl-like luster simply by mixing with a compounding component at the time of production of a target product. The gloss is also constant.
