Problems solved by technology

However, in the emulsification method using these surface chemical methods, polyhydric alcohol must be added as an essential component for emulsification, so that the sensory-acceptable product is restricted, that is, the appearance and formulation are restricted. Pre-study takes time
In addition, when it comes to the burden of production, there are the following disadvantages: it must be made to produce polyol gel, and it takes a long time for emulsification. In addition, the oil phase and polyol before emulsification can be dispersed as uniformly as possible with a mixer. The amount of formulation, that is, the formulation with oil phase and less polyols, cannot be manufactured
Diglycerol mono fatty acid esters with self-emulsifying properties are also distributed, but their self-emulsifying properties are weak and good emulsions cannot be obtained

[0109] Hereinafter, although an Example is given and this invention is demonstrated concretely, this invention is not limited to these examples.

[0110] [Composition analysis of raw material polyglycerol]

[0111] Three types of polyglycerols used as raw materials for component A of the present invention (products manufactured by Taiyo Chemical Co., Ltd.: Great Oil D-10, Great Oil D-11, Great Oil D-12) and polyglycerols used for comparison Polyglycerin composition of 4 kinds of polyglycerols (products manufactured by Taiyo Chemical Co., Ltd.: Great Oil S-10, Great Oil S-11, Great Oil S-12, Great Oil S-13) used as raw materials of fatty acid esters The measurement was carried out by gas chromatography, and the analysis results are shown in Table 1. Each composition analysis value was calculated by the area percentage method. In addition, when polyglycerin contains dimer or trimer cyclic substances, the polyglycerin composition analysis values ​​of dimers and trimers represen...

[0127] Examples 1-14 [oil-in-water emulsified cosmetic material]

[0128] An oil-in-water emulsified cosmetic material containing component A (polyglycerin fatty acid ester using any of the polyglycerols in Analysis Examples 1 to 3 as a raw material), component B, and component C was prepared. Here, components other than those in Examples 1, 2, 6, 9, and 10 contained component D. The recipes of the produced oil-in-water emulsified cosmetics are shown in Tables 5 to 10. In Tables 5 to 10, raw material polyglycerol: analysis examples 1, 2, and 3 show that the polyglycerol used as the raw material of polyglycerol fatty acid ester is the raw material polyglycerol of analysis examples 1, 2, and 3, respectively. .

[0220] Example 15 [moisturizer]

[0221] Moisturizers of oil-in-water emulsified cosmetics with the formulations shown in Table 27 were prepared.

[0222] First, the raw materials (1) to (7) were put into a 100 ml stainless steel container, and mixed and dissolved by dispersion stirring (3000 rpm) while heating to 70° C., to obtain an oil phase. Separately, raw materials (8) to (11) were mixed and dissolved at 70° C. with dispersion stirring (1000 rpm) to obtain an aqueous phase. Thereafter, the oil phase at 70°C was added to the water phase stirred at 70°C with a disperser (1000 rpm).

[0223]Further, the raw material (12) was added while continuing the dispersing stirring, and the raw material (13) was further added, followed by dispersing and stirring for 10 minutes. Cool to 30°C while continuing stirring, and take out the oil-in-water emulsified cosmetic material. By leaving still at 25 degreeC for 24 hours, 96 g of oil-in-water emulsified cosmetics moisturizers were ob...

Abstract

An oil-in-water-type emulsified cosmetic preparation containing a polyglycerol / fatty acid ester as a surfactant. It has high stability to temperature fluctuations and gives an excellent use feeling. The oil-in-water-type emulsified cosmetic preparation comprises 1) a surfactant comprising a polyglycerol / fatty acid ester which has a hydroxy value of 450 to 700 and in which 50 to 100% by mass of all constituent fatty acid residues are accounted for by a C16-18 fatty acid residue and the polyglycerol has a specific polymerization degree distribution, 2) an oily matter, and 3) water.

Description

technical field [0001] The present invention relates to an oil-in-water emulsified cosmetic containing 1) a polyglyceryl fatty acid ester as a surfactant (or emulsifier), 2) an oily component, and 3) water, and a method for producing the same. More specifically, it relates to an oil-in-water emulsified cosmetic material using polyglycerol fatty acid ester, which is excellent in emulsification stability such as stability under various temperature conditions (hereinafter referred to as "temperature stability"), and is also It relates to an oil-in-water emulsified cosmetic material which is also excellent in usability and a method for producing the same. Background technique [0002] Conventionally, polyoxyethylene-based surfactants have often been used as surfactants in oil-in-water emulsified cosmetics such as ointments, creams, emulsions, and cosmetic serums. Examples of polyoxyethylene-based surfactants include polyoxyethylene sorbitan fatty acid esters, polyethylene glyco...
