Detailed description of the invention
Below the composition of the cosmetics for skin of the present invention is described in detail respectively。
[composition (A)]
As alkyl ether carboxylic acid and the salt thereof of the composition (A) used in the present invention, it is by the alkyl ether carboxylic acid as raw material is obtained with alkaloid substance neutralization。With in alkaloid substance and afterwards, depending on the concentration of the alkaloid substance used, the alkyl ether carboxylic acid as raw material is formed as alkyl ether carboxy acid salt in whole or in part。Individually below " alkyl ether carboxylic acid as raw material ", " alkaloid substance " and " alkyl ether carboxylic acid obtained after neutralization and salt thereof " is specifically described。
<alkyl ether carboxylic acid as raw material>
Alkyl ether carboxylic acid as raw material is the material represented by following formula (I)。
R-O-(CH2CH2O)nCH2-COOH(I)
(in formula, R represents the alkyl that carbon number is 10～18, and n represents the number of average out to 0.5～10。)
From the view point of the stability of cosmetics for skin and detergency, as R, it is preferable that carbon number is alkyl or its mixture of 12～16, more preferably carbon number is alkyl or its mixture of 12～14。It addition, the average addition molal quantity of ethylene oxide is preferably 1～8, more preferably 2～6, more preferably 2～4。
As the alkyl ether carboxylic acid of raw material can use a kind or two or more, but owing to the dissolubility of the alkyl ether carboxylic acid as raw material is low, spatter property is unexcellent, so needing when using to neutralize to improve its clean power with alkali。The alkali being generally used for neutralizing alkyl ether carboxylic acid is potassium hydroxide or the such alkali metal of sodium hydroxide, the salt hydrophilic formed is high, therefore, it is difficult to oil preparation emulsifying and easily causing is separated, and the reserved that alkyl ether carboxylic acid's oil preparation of being difficult to improve in preparation is on skin。Therefore, in order to generate stable oil-in-water emulsion type cosmetic preparation, it is necessary it is neutralized to form alkyl ether carboxy acid salt in whole or in part with the alkaloid substance comprising organic base by this as the alkyl ether carboxylic acid of raw material, guarantee detergency such that it is able to formed and prevent the stable emulsification cosmetic being separated, and, improve the reserved (also referred to as " reservation oil mass ") cleaning rear oil preparation contained by emulsification cosmetic on skin。
<alkaloid substance>
As being used for neutralizing the alkaloid substance of the above-mentioned alkyl ether carboxylic acid as raw material, it comprises organic base, and comprises inorganic base alternatively。
As organic base, it is possible to enumerate alkanolamine, for instance diethylaminoethanol, methylaminoethanol, aminomethylpropanol, dimethylaminoethanol, isopropanolamine, triethanolamine, isopropanoldimethylamine, ehtylethanolamine and mixture thereof etc.；And basic amino acid, for instance L-arginine, alanine, glycine, serine, lysine, glutamine and mixture thereof etc.。Wherein, it is preferable that in aminomethylpropanol, triethanolamine and L-arginine a kind or two or more。

The cosmetics for skin of comparative example 27 adopts the composition identical with embodiment 1, but its preparation method is as follows。
First, at 75 DEG C, composition (B) (caprylic/capric triglyceride) is added in beaker as oil phase A '。
Secondly, at 75 DEG C, alkyl ether carboxylic acid's (polyoxyethylene (6) lauryl ether carboxylic acid) and alkaloid substance (triethanolamine) as raw material is added in beaker together with composition (C) (water), using the rotating speed of 200rpm while stirring makes the alkyl ether carboxylic acid as raw material be neutralized by alkaloid substance and obtain composition (A), form transparent aqueous phase B '。
Then, above-mentioned oil phase A ' is added to aqueous phase B ' in, stir 20 minutes with the rotating speed of 200rpm, thus forming oil-in-water emulsion type cosmetic preparation。
For this oil-in-water emulsion type cosmetic preparation prepared, evaluating its stability (just preparing), evaluation result is " ▲ (layering) "。
Thus can be clear and definite, in the cosmetics for skin of comparative example 27, owing to not having to adopt preparation method as the present invention, therefore, the evaluation relating to stability (just preparing) is poorer than embodiment 1。
