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 take soap base class (fatty acid adds alkali neutralization and forms) as main, pH value is conventionally in 9.0-10.5 left and right, clean product of this class, foaming power is good, and foam is abundant fine and smooth, and scrubbing is totally thorough, with rear, easily rinse well, give skin clean salubrious sense.The soap base facial cleaning cream that various brands in the market have a or several moneys to be extensively subject to consumer acceptance and to like.
Soap base facial cleaning cream has very strong cleaning effect, and on the one hand, consumer is use habit, likes foam abundant in clean process and the sensation of washing totally; On the other hand, due to Monoethanolamine Lauryl Sulfate, defat is higher, especially can make winter dermal sensation 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, take aminoacid and fatty acid as raw material, synthesize, 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 conventionally in 5.0～8.0 left and right, approach the pH value of healthy Asians's skin, wash skinfeel moist not tight, become the exploitation focus of current daily use chemicals research.The salt (sodium salt/potassium salt) that on market, topmost two amino acid surfactants are alkyl-glutamic acid and alkyl glycine, but amino acid surfactant cost is generally higher, generally in expensive goods, uses.
The large manufacturer of amino acid surfactant mainly contains the companies such as Japanese aginomoto, standing grain large (Croda), P&G (P & G), DOW Chemical (Dow) at present.By the amino acid surfactant of two kinds, be that glutamic acid-type and glycine class compare, comparison other be Japanese aginomoto company in the more welcome AMISOFT series of Chinese market (glutamic acid) 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, have the weak acid pH value similar to skin, environmental protection, smooth, can do similar crystal type product.
AMILITE G series (glycine): representative products GCK-12K/GCK-12/GCS-11(powder)/GCK-11/GCK-11F, so its feature is at gentle amino acid system, without anaphylaxis, in neutral environment, foaming capacity is strong, can do similar soap base foam abundant, clean the product that sensation is cleaned.
According to the research of aginomoto company, fatty acyl glutamate, Glu surfactant is used skinfeel comparatively moist, is faintly acid; Fatty acyl glycinate surfactant skinfeel is comparatively salubrious, is neutral to alkalescence.
Fatty acyl glutamate, Glu facial cleaning cream is applicable to doing moist facial cleaning cream, in available and anti-aging product, adopts 25% high-load and by adjusting the way of pH crystallization control, relatively easily thickening.What the disclosed a kind of amino acid type weak acid facial cleanser of patent publication No. CN102048653B mainly adopted is exactly sodium lauroyl glutamate.
On market, there have been a lot of brands to issue clean product of amino acid pattern, for example, take sodium lauroyl glutamate as main SK-II facial treatment cleanser.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 that adopts high-load, and consumption is approximately 20～30%, by regulating pH value, make part lauroyl glutamic acid separate out thickening, cost compare is high, the obfuscation of mastic outward appearance, 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 is fine and smooth abundant, and cleaning capacity is strong, and skinfeel is salubrious.In glycinate surfactant with cocos nucifera oil acyl glycine potassium for better, on market take cocos nucifera oil acyl glycine potassium two types below clean main product has: the first is the low viscosity amino acid surfactant solution of not thickening substantially, take the liquid foam pump packaging product of Uniliver as representative; The second is by adding a large amount of thickening agent hydroxypropyl starch phosphate esters or fatty acid or the composite facial cleaning cream of soap base, take the facial cleaning cream of Uniliver as representative.For example, the patent US7867961 of aginomoto company and the patent US6903057 of Uniliver carry out thickening by starch.
From patent US6903057, in the time of will making facial cleaning cream shape due to cocos nucifera oil acyl glycine potassium surfactant, be difficult to carry out thickening, 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, during use, have the thick texture of starch, be difficult for coating, smooth degree is inadequate.

Pearl Concentrate contains advantages of good crystallization, the EGDS flat crystal of approximately 30～50 microns, and pearl effect is good.In technique, need add at a lower temperature, now EGDS flat crystal dissolubility in the system of low temperature is little, and crystal size is basicly stable, can keep good pearl effect.
Pearling agent is EGDS solid, is non-ordered arrangement, therefore there is no pearl effect.In technique, under higher temperature, add, can dissolve and be scattered in surfactant system, cooling after crystallize out slowly, generally speaking, pearling agent crystal is less than the crystal in Pearl Concentrate, pearl effect can be far short of what is expected.
If only add the pearling agent of high concentration, all in thermal process, add, the pearly-lustre that crystallisation by cooling goes out so, effect is poorer than the effect of outer cold rnning Pearl Concentrate, and crystalline particle is smaller, and specific surface area is large, is subject to influence of temperature change large.And preparation of the present invention adopts cold rnning Pearl Concentrate; there is large particle diameter EGDS flat crystal; even if temperature raises slightly, that first dissolve is also the granule pearling agent EGDS that specific surface area is large, thereby protects and improved in Pearl Concentrate the stability of the EGDS flat crystal of 30～50 microns.Therefore, high low temperature, respectively with pearling agent and Pearl Concentrate, has superiority than the pearling agent EGDS solid that adds separately high dose, also than entirely adding Pearl Concentrate, has superiority, and can also save cost.
But it is pointed out that and combine that to use pearling agent and Pearl Concentrate be preferred version of the present invention, use also can obtain facial cleaning cream compositions of the present invention separately.
