Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for washing, which is suitable for a hair washing such as shampoo.

[0002]

2. Description of the Related Art In a cleaning agent such as a shampoo, a pearling agent is often used in order to give a beautiful appearance. As such a pearlizing agent, for example, powder such as titanium mica or wax-based pearling agent such as monoester or diester of stearic acid of ethylene glycol is used, but titanium mica is not often used because of its large specific gravity. In many cases, a saturated fatty acid ester of ethylene glycol was mainly used. However, a saturated fatty acid ester of ethylene glycol may cause sedimentation of pearls with the passage of time due to a combination with other prescription components, which has been a problem to be solved.

On the other hand, xanthan gum is generally used as a thickener in cosmetics, and has been known to have an action of improving the stability of an emulsion. However, it is not known that this has an effect of suppressing the separation of pearls of a saturated fatty acid ester of ethylene glycol, which is caused by silicone, especially high-viscosity silicone. Furthermore, cationized polymers such as cationized cellulose and cationized guar gum are known as polishes, but have never been known to contribute to the stabilization of the system.

[0004] Further, silicones such as dimethicone are widely used in the field of hair cosmetics for the purpose of excellent gloss effect and improvement of combability. It was not known at all to have any negative effect on the stability of the pearl, nor was it known that this effect would become significant as the viscosity of such silicones became 50,000 to 500,000 centistokes.

[0005]

SUMMARY OF THE INVENTION The present invention has been made under such circumstances, and it is an object of the present invention to provide a means for stably containing pearl in a silicone-containing cleaning cosmetic. I do.

[0006]

In view of such circumstances, the present inventors have conducted intensive studies on means for stably containing pearl in a silicone-containing cleaning cosmetic, and as a result, have found that xanthan gum and cationized It has been found that such a system can be stabilized by containing a polymer, and the present invention has been completed. Hereinafter, the present invention will be described in detail focusing on embodiments.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (1) Silicone which is an essential component of the present invention The silicone which is an essential component of the present invention can be used without any particular limitation as long as it is a silicone used in the field of cosmetics. Yes, for example, dimethicone, methylphenylpolysiloxane, α-methylphenyl-modified methylpolysiloxane, acryl-modified methylpolysiloxane, amino-modified silicone and the like can be preferably exemplified, and the degree of polymerization is 1 to 100,000,000 centistokes in terms of viscosity. Can be exemplified. Among these, preferred as essential components of the present invention are 10,000 to 100,000
0 centistokes, more preferably 50,000-50
0000 centistoke high viscosity silicone.
This is because silicones of this viscosity tend to have an unusual tendency to reduce pearls, and the technology of the present invention can stabilize them irrespective of viscosity, so that the effect of stabilizing pearls of the present invention is large. is there. Since such silicones are already widely marketed, there is no problem in obtaining them. Such silicones can be contained as they are, or they can be contained in a form that has been subjected to an intermediate treatment by emulsification in advance. It is preferable to include those that have been subjected to a treatment such as emulsification in advance since the stability is further improved. The preferred content of the silicone in the cleaning cosmetic composition of the present invention is 0.01 to 10% by weight, and more preferably 0.05 to 5% by weight. This is because if the amount of silicone is too small, the effect such as improvement in gloss cannot be obtained,
If the amount is too large, the system may become unstable.

(2) Saturated fatty acid ester of ethylene glycol which is an essential component of the present invention The saturated fatty acid ester of ethylene glycol which is an essential component of the present invention is widely used as a pearling agent in the field of detergents. is there. Such esters include:
Preference is given to lauric acid esters, myristic acid esters, stearic acid esters, behenic acid esters and the like, among which stearic acid esters are particularly preferred. Ethylene glycol esters include monofatty acid esters and difatty acid esters, with difatty acid esters being particularly preferred. These esters are already commercially available as raw materials for cosmetics, and are readily available.
Further, in the cosmetic for cleaning of the present invention, such an ester can be contained alone or in combination of two or more. The content of the fatty acid ester of ethylene glycol in the cosmetic for washing of the present invention is preferably 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, and still more preferably 0.1 to 5% by weight.
1 to 3% by weight. This is because if the amount is too small, the pearly feeling will not be obtained, and if the amount is too large, the effect will level off.

(3) Xanthan gum which is an essential component of the present invention Xanthan gum is a thickening polysaccharide of a microbial metabolite produced by fermenting dextrose and the like, and has been used as a raw material for cosmetics and food since ancient times. This includes:
The effect of stabilizing emulsification is known. This one is
Many types are commercially available, and it is possible to use them in the present invention. The preferred content of xanthan gum in the cleansing cosmetic composition of the present invention is from 0.01 to 2
%, More preferably 0.3 to 1% by weight. This is because if the content of xanthan gum is too small, it may not be possible to stabilize, and if it is too large, the viscosity may be too high and the fat solubility may be impaired.

(4) Cationized polymer which is an essential component of the present invention The cationized polymer which is an essential component of the present invention is obtained by etherifying a polysaccharide such as cellulose or guar gum with aminomethanol or the like and cationizing it. As commercial products, there are already commercially available cationized celluloses such as Leogard MGP (manufactured by Lion Corporation), Catinal LC-100 and Catinal LC-200 (all manufactured by Toho Chemical Co., Ltd.). 14S, Jaguar C17 (all manufactured by Sansho Co., Ltd.)
Is mentioned. Among these, it is preferable to contain a cationized guar gum as the cationized polymer, and it is particularly preferable to contain Jaguar C13S. Of course, the cosmetic for cleaning of the present invention may contain only one kind of the cationized polymer, or may contain two or more kinds thereof in combination. Such cationized polymers have the effect of stabilizing pearlescent agents such as ethylene glycol distearate. The preferred content of the cationized polymer in the cosmetic for washing of the present invention is 0.01 to 0.01.
-5% by weight, more preferably 0.05-1% by weight.
It is. This is because if the amount is too small, the stabilizing effect may not be obtained, and if the amount is too large, the washing property may be impaired. (5) Cosmetic for cleaning of the present invention The cosmetic for cleaning of the present invention is characterized by containing silicone, a saturated fatty acid ester of ethylene glycol, xanthan gum, and a cationized polymer. Examples of the cleansing cosmetics include facial cleansers, whole body cleansings, and hair cleansings.
