【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel water-in-oil type (hereinafter referred to as W/O type) emulsified cosmetic manufacturing method, and more specifically, an emulsification process conventionally known as the so-called "gel emulsification method". It concerns the improvement of the law. The following three methods have been known as the "gel emulsification method" for a long time as a method for producing W/O type emulsified cosmetics. That is, a gel consisting of a lipophilic surfactant and a polyhydric alcohol (or an aqueous solution thereof) is prepared. A gel consisting of a lipophilic surfactant and an aqueous amino acid solution (or an aqueous amino acid salt solution) is prepared. A gel consisting of a lipophilic surfactant and an aqueous organic acid solution (or an aqueous organic acid salt solution) is prepared. The gist of the method was to add the gel obtained by the above method to an oily component and disperse it, and then add water in some cases. However, in each of the above-mentioned conventional methods, (a) If some additive is added to the aqueous phase, the gel will generally become unstable, and the stability of the final emulsified cosmetic will also decrease. be. (b) There are many restrictions in obtaining a stable gel, the process may be complicated, and the flexibility in formulation may not be effective. In reality, it was not always easy to apply it to actual products because of the following drawbacks. Therefore, the inventors of the present invention carefully considered the above-mentioned drawbacks, and as a result of continuing intensive research, we solved these problems by using a gel consisting of an aqueous solution of a water-soluble polymer and a lipophilic surfactant that is liquid at room temperature. The present invention was completed by successfully solving the drawbacks. That is,
The present invention is characterized in that a gel is prepared by adding an aqueous solution of a water-soluble polymer to a lipophilic surfactant that is in a liquid state at room temperature under stirring, and the gel is added to an oily component for dispersion. This is a method for producing a W/O type emulsified cosmetic. Water-soluble polymers used in the present invention include sodium alginate, pectin, sodium pectate, sodium carboxymethyl cellulose,
Carboxyvinyl polymers and the like can be used, and these may be used alone or in combination. Similarly, as the lipophilic surfactant used in the present invention, those commonly used in the field of cosmetics can be used, such as glycerin monooleate, glycerin diolate, diglycerin monooleate, diglycerin diolate, glycerin monooleate, These include isostearate, glycerin diisostearate, diglycerin monoisostearate, diglycerin diisostearate, and the like, and these can be used alone or in combination. By the way, the amount of lipophilic surfactant used to prepare the gel in the present invention is 0.5 to 8% by weight, more preferably 1% by weight based on the total formulation.
~5% by weight. If it is less than 0.5% by weight, the emulsion will lack stability, and if it is more than 8% by weight, it will not be pleasant to the touch. Similarly, the amount of water-soluble polymer used in the present invention is preferably 1 to 10 times the weight of the lipophilic surfactant as a 0.1 to 5% aqueous solution. In a water-soluble polymer aqueous solution with a concentration of 0.1% or less, the prepared gel becomes unstable;
At higher concentrations, the viscosity of the aqueous solution itself may be too high,
It is also difficult to prepare such a highly concentrated aqueous solution depending on the type of water-soluble polymer, so it is not suitable. Furthermore, if the amount of the water-soluble polymer aqueous solution is less than 1 times the weight of the lipophilic surfactant, it will be difficult to form a gel, and even if it does form, it will be unstable; It is also unsuitable because the amount of water that can be retained is close to the limit and the gel may be destroyed. In the present invention, water is prepared as a water-soluble polymer aqueous solution and added, but the conventional "gel emulsification method"
Similarly, in addition to adding a part of the water as a water-soluble polymer aqueous solution, a part of the water may be further added to a W/O emulsion obtained by adding and dispersing a gel in an oily component. . In addition, the total water content in the W/O type emulsified cosmetic is:
As mentioned above, it is necessary that the amount is 10 times or less the weight of the lipophilic surfactant, and if more is added, the stability of the W/O emulsion cosmetic will deteriorate. To produce the W/O type emulsified cosmetic of the present invention,
First, a water-soluble polymer is added to a predetermined amount of water and uniformly swelled and dissolved to obtain a water-soluble polymer aqueous solution. The water-soluble polymer aqueous solution is gradually added to a lipophilic surfactant that is in a liquid state at room temperature under stirring to form a gel. On the other hand, if the oily component contains a solid component, it is heated to become a liquid, and the prepared gel is gradually added thereto under stirring to disperse and emulsify.
Thereafter, necessary additional ingredients are added and cooled to obtain a W/O type emulsified cosmetic. In the above process, water is added as a water-soluble polymer aqueous solution, but some of the water may be added after emulsification. Since the total amount of gel can be adjusted by adding water later, it is also possible to improve the efficiency of the process by appropriately selecting the amount of water to be added depending on the manufacturing process conditions. Furthermore, the effects obtained by the present invention include: (a) The water-soluble polymer has a high water-holding capacity, the prepared gel has good stability, and the gel can be stored for a long time. b Moisturizing agents such as propylene glycol and butylene glycol, which have been difficult to use because they destabilize the gel, can be added. c The obtained W/O type emulsified cosmetic has a crisp feel when used, and has an excellent moisturizing effect to keep the skin moist. d Syneresis of the internal aqueous phase, which is a drawback of conventional W/O type emulsified cosmetics, is less likely to occur. The following points can be mentioned. Hereinafter, the effects of the present invention will be explained based on Examples. Example (Cream) (Composition) Weight% (1) Glycerin triisostearate 10.0 (2) Glycerin triisooctanate 10.0 (3) Squalane 6.0 (4) Beeswax 2.0 (5) Ceresin wax 1.0 (6) Di Glycerin diisostearate 3.0 (7) Sodium carboxymethyl cellulose (3
% aqueous solution) 20.0 (8) Propylene glycol 7.0 (9) Purified water 40.8 (10) Preservative trace amount (11) Flavor 0.2 (Production method) A Prepare (7). A gel is prepared by adding B (7) into (6) under stirring. C. (1) to (5) are uniformly dissolved at 70°C. Add B to DC under stirring and disperse uniformly. E Add (8) to (10) and disperse uniformly. Add F (11). G Cool to obtain W/O type cream. [Comparative Example] Prepare A (7) (by conventional emulsification method). B Uniformly dissolve (1) to (6) at 70°C. C (7) to (10) are uniformly dissolved at 70°C. D Uniformly disperse and emulsify C into B. Add E (11). F Cool to obtain W/O type cream. [Comparative example] (by conventional gel emulsification method) In the composition of the example, (7) carboxymethyl cellulose sodium (3% aqueous solution) 20.0%, (9) purified water 40.8%, (7) 65% sorbitol aqueous solution 5.0%
(9) Substitute 55.8% of purified water to obtain a W/O cream according to the manufacturing method of the example. The results of a comparative evaluation of the three types of W/O creams obtained as described above in terms of particle size, high temperature stability, and texture are shown in the table.
It is clear that type O cream is superior in each respect. 【table】
