Description
Technical field
The present invention relates to water-in-oil type cosmetic, in more detail, relate to water-in-oil type cosmetic with good usability and stability.
Background technology
In the past,, make it be used for cosmetics, need carry out a large amount of medium type wet type dispersion treatment such as powder body dispersant ball milling it because powder particles has stronger cohesive force.As the powder body dispersant, the high molecular weight surface activating agent of preferred polymolecularity.But when using a large amount of powder body dispersants, will appear at " sense of being clamminess " and problems such as " smoothening property are poor " on the usability; And opposite, be to improve usability, when using a small amount of powder body dispersant, produce coagulation between the powder body, the viscosity that the goods that obtained appear in the result rises, takes place phenomenons such as gelation and discharge opeing.Particularly, in the water-in-oil type cosmetic, when using the powder body dispersant, influence emulsifier, the emulsifying during generation emulsifying is bad, and emulsion droplet generation coagulation and caking when placing for a long time.
In recent years, the high sun care preparations of spf value (ultraviolet protection index) goes on the market one after another, and in most of the cases, these cosmetics are used in combination UV absorbent with powder particles such as titanium oxide, zinc oxide, and for improving spf value, major part contains the powder particles of high dispersion state.In addition, containing under the situation of powder particles, be dispersed in " the puckery sense " that will produce in the water on the sense of touch etc.; And it is better to be dispersed in the oil sense of touch.Technology about the sub-powder body of disperse particles in oil, reported various technology in the existing document, comprising handling the method that powder body, silicone oil and specified polysiloxane-based surfactant etc. obtain stable water-in-oil emulsion by aggregate surface, this method is documented in the spy and opens on the clear 63-215615 communique, but this technology can not obtain stability and usability effect fully.In addition, comprise by combination and carry out surface-treated powder particles, silicone oil with organo-silicon compound and contain the specified polysiloxane-based surfactant of chain alkyl, obtain the method for the water-in-oil emulsion of good usability and stability, this method is documented in the spy and opens on the 2001-278737 communique.But,, in the adjustment of usability etc., be restricted because this method needs specified surfactant.
Therefore, wish to work out to have long-time stability and the good water-in-oil type cosmetic that contains powder particles of usability.
Summary of the invention
