Description
Technical field
The invention belongs to household chemicals technical field, be specifically related to the preparation method of a kind of amino acid pattern pearly-lustre facial cleaning cream compositions and this skin care compositions.
Background technology
Facial cleaning cream is daily cleaning cosmetic product, the facial cleaning cream of prior art is mostly based on soap base class (fatty acid adds alkali neutralization and forms), pH value is usually at about 9.0-10.5, this kind of clean product, foaming power is good, and foaming abundancy is fine and smooth, and scrubbing is totally thorough, easily rinse well with rear, to the clean salubrious sense of skin.Various brands in the market have a or a few money extensively by consumer acceptance and the Soap-base facial cleanser liked.
Soap-base facial cleanser has very strong cleaning effect, and on the one hand, consumer is use habit, the sensation liked foam abundant in clean process and wash totally; On the other hand, due to Monoethanolamine Lauryl Sulfate, defat is higher, and dermal sensation especially can be made winter dry, and zest is larger.
Meanwhile, clean product of amino acid surfactant type is also subject to consumer's attention just day by day.This surfactant source is natural, synthesize for raw material with aminoacid and fatty acid, because raw material is renewable, genus organism component part, is easy to biodegradation and toxicity is low, therefore amino acid pattern facial cleaning cream milder pro-skin, pH value is usually about 5.0 ~ 8.0, close to the pH value of healthy Asians's skin, wash skinfeel moist not tight, become the exploitation focus of current daily use chemicals research.On market, topmost two amino acid surfactants are the salt (sodium salt/potassium salt) of alkyl-glutamic acid and alkyl glycine, but amino acid surfactant cost is general higher, generally uses in expensive goods.
The large manufacturer of current amino acid surfactant mainly contains Japanese aginomoto, the large company such as (Croda), P&G (P & G), DOW Chemical (Dow) of standing grain.By the amino acid surfactant of two kinds, namely glutamic acid-type and glycine class compare, comparison other be Japanese aginomoto company in the more welcome AMISOFT series (glutamic acid) of Chinese market and AMILITE G series (glycine), both features are as shown in table 1.
AMISOFT series (glutamic acid): representative products LS-11/MK-11/MS-11/HS-11/CT-12S/22SB.Its feature is that gentle low irritability, natural origin (molasses fermented), amino acid system (non-oxirane system), moisturizing good (larger hydrophilic molecule), skinfeel are good, gentle, has the weak acid pH value similar to skin, environmental protection, smooth, similar crystal type product can be done.
AMILITE G series (glycine): representative products GCK-12K/GCK-12/GCS-11(powder)/GCK-11/GCK-11F, so its feature is at the amino acid system of gentleness, without anaphylaxis, in neutral environment, foaming capacity is strong, similar soap base foaming abundancy can be done, clean the product that sensation is cleaned.
According to the research of aginomoto company, fatty acyl glutamate, Glu surfactant uses skinfeel comparatively moist, in faintly acid; Fatty acyl glycinate surfactant skinfeel is comparatively salubrious, in neutral to alkalescence.
Fatty acyl glutamate, Glu facial cleaning cream is applicable to doing moist facial cleaning cream, available with anti-aging product, adopts the high-load of 25% also by adjusting the way of pH crystallization control, relatively easily thickening.What disclosed in patent publication No. CN102048653B, a kind of amino acid type weak acid facial cleanser mainly adopted is exactly sodium lauroyl glutamate.
Market there is a lot of brand issued clean product of amino acid pattern, such as, SK-II facial treatment cleanser based on sodium lauroyl glutamate.Its material composition: water, sodium lauroyl glutamate, propylene glycol, PEG-150 distearate, overlay film yeast fermentation Product filtrate, PCA sodium, ethylene glycol stearate, coconut oleoyl amine MEA, butanediol, phenethanol, methyl hydroxybenzoate, dog rose berry extract, stearmide AMP, propyl hydroxybenzoate, triclosan, hydrolyzed yeast extract, glycyrrhizic acid dipotassium, hydrolysis Semen Lini extract.Its major technique is the sodium lauroyl glutamate adopting high-load, and consumption is approximately 20 ~ 30%, by regulating pH value, make part lauroyl glutamate separate out thickening, cost compare is high, and mastic outward appearance shades, foam is abundant not, uses and feels partially moist, variant with deep clean.
The moisturizing sense of glycinate surfactant and foaming capacity are between glutamate, Glu surfactant and soap base surfactant, and pH is between neutrality and alkalescence, and foam exquisiteness is abundant, and cleaning capacity is strong, and skinfeel is salubrious.Be better with cocos nucifera oil acyl glycine potassium in glycinate surfactant, market there are two types below based on clean product of cocos nucifera oil acyl glycine potassium: the first is the low viscosity amino acid surfactant solution of not thickening substantially, with the liquid foam pump packaging product of Uniliver for representative; The second is by adding the composite facial cleaning cream of a large amount of thickening agent hydroxypropyl starch phosphate or fatty acid or soap base, with the facial cleaning cream of Uniliver for representative.Such as, the patent US7867961 of aginomoto company and the patent US6903057 of Uniliver carries out thickening by starch.
From patent US6903057, owing to being difficult to carry out thickening when cocos nucifera oil acyl glycine potassium surfactant will make facial cleaning cream shape, so the consumption of thickening starch is very high, this not only makes mastic outward appearance lack fine and smooth gloss, also can raise the cost, have the thick texture of starch during use, be not easily coated with, smooth degree is inadequate.
