Description

  The present invention relates to a candelilla wax dispersion composition used as a raw material of a hair treatment agent and the like.

  Candelilla wax is used as a raw material for hair treatment agents such as hair styling agents. In hair styling compositions, it is general to use candelilla wax as a hair styling component, and use a higher fatty acid-based anionic surfactant together with a nonionic surfactant as a surfactant for dispersing the candelilla wax (for example, see Patent See paragraph 0014 of document 1). When the compounding amount of candelilla wax is increased in order to enhance hair styling properties, the use frequency of higher fatty acid-based anionic surfactant increases. Patent Document 2 states that the combined use of POE (20) behenyl ether and betaine lauryl dimethylaminoacetate is superior to POE (20) behenyl ether alone as a surfactant for dispersing candelilla wax. Paragraph 0017).

JP 2002-370937 A JP-A-11-263915

  It is as described above that a surfactant suitable for dispersing candelilla wax is proposed. Since the type of surfactant is selected according to the use of the composition containing the candelilla wax, the formulation of the specific surfactant is limited, and then the candelilla wax is used using a nonionic surfactant. A proposal to disperse is also sometimes desirable.

  In view of the above circumstances, the present invention does not include a higher fatty acid-based anionic surfactant, and uses a nonionic surfactant to reduce the dispersibility of candelilla wax after reducing the amidobetaine-type amphoteric surfactant to a predetermined amount or less. The purpose is to provide an enhanced composition.

  As a result of intensive studies by the present inventors, it has been found that the use of a predetermined polyoxyethylene cetyl ether or polyoxyethylene polyoxypropylene cetyl ether has good dispersibility of candelilla wax. Further, in order to enhance the dispersibility, it has been found that it is preferable to adjust the amount of candelilla wax to suppress the viscosity. Based on these findings, the present invention has been completed.

  That is, the candelilla wax dispersion composition according to the present invention is a candelilla wax, one or two or more cetyl ether nonionic surfactants selected from polyoxyethylene cetyl ether and polyoxyethylene polyoxypropylene cetyl ether, Water is blended, the HLB value of the cetyl ether nonionic surfactant is 11.0 or more and 16.0 or less, no higher fatty acid anionic surfactant is blended, and 1 amide betaine type amphoteric surfactant is used. It is characterized by a blending amount of less than 0.5% by mass or not blended, and a viscosity of 20,000 mPa · s.

  The ratio (B) / (A) of the blending amount (B) of the cetyl ether nonionic surfactant to the blending amount (A) of the candelilla wax is preferably 0.2 or more. This ratio is particularly suitable for the dispersibility of candelilla wax.

  In the candelilla wax dispersion composition according to the present invention, the volume average particle diameter of the candelilla wax is preferably 500 nm or less. The volume average particle diameter is a value determined by measurement by a laser diffraction / scattering method.

  The candelilla wax dispersion composition according to the present invention is preferably transparent or translucent. Here, “semi-transparent” refers to transparency in which the background can be confirmed when the candelilla wax dispersion composition in a bottomed cylindrical glass container having a diameter of 4 cm is visually confirmed from the front.

  Further, the candelilla wax dispersion composition according to the present invention is preferably used as a raw material to be blended with a hair treatment agent such as a hair styling agent. By using the composition according to the present invention having good dispersibility of candelilla wax as a raw material, it becomes easy to improve the dispersibility of candelilla wax in a hair treatment agent, and candelilla compounded in a hair treatment agent The amount of wax can be easily increased.

  The candelilla wax dispersion composition according to the present invention suppresses the viscosity by limiting the amount of the candelilla wax, and disperses the candelilla wax in water with a cetyl ether nonionic surfactant having a predetermined HLB value range. Even when the anionic surfactant is not blended and the amidobetaine-type amphoteric surfactant is blended in an amount of less than 1.5% by mass, the dispersibility of the candelilla wax is high.

  The present invention is described below based on the candelilla wax dispersion composition according to the embodiment of the present invention (hereinafter, the “candelilla wax dispersion composition according to the present embodiment” may be referred to as “the present composition”). explain. The present composition contains candelilla wax, a predetermined cetyl ether-based nonionic surfactant, and water (the amount of water is, for example, 50% by mass or more).
