Description

Double-deck essence lotion of a kind of water and milk and preparation method thereof

Technical field

The invention belongs to skin care applications, be specifically related to a kind of cosmetics, the particularly double-deck essence lotion of a kind of water and milk, and the preparation method of this emulsion.

Background technology

Common product emulsion, often more greasy, skin is difficult to absorb, and the product of pure water dosage form, owing to not containing oils and fats, can not add more oil components, therefore its skinfeel is drier and more astringent, can not maintain permanent moisturizing effect after smearing.Commercially available double-deck product emulsion, is divided into water layer and oil reservoir usually, and give skin water balance by water layer, make trickle Moisture factor infiltrate into the skin bottom, oil reservoir then gives skin moist sense, forms the protecting film of thin layer on skin surface.Because the usual upper strata of this double-layer product is oil-phase component, lower floor is water-phase component, not containing emulsified component, will layering within very short time after mixing, and a kind of composition only poured out wherein can be easy in consumer's use procedure.

If upper strata is emulsion, lower floor is aqueous phase, then easily face following technical problem: (1) due in formula emulsifying agent select improper, water and milk bilayer is difficult to layering within a certain period of time; (2), after the double-deck elite layering of water and milk, the aqueous phase of bottom is muddy, and outward appearance is bad; (3) upper strata of the double-deck elite of water and milk is emulsion, and character is unstable, thus surface has oil content precipitation.

Summary of the invention

The object of the invention is the technical problem for solving above, provide a kind of can fast hierarchical, the clear novelty of outward appearance, emulsion property stablize, the double-deck essence lotion of water and milk of functional diversities.

Another object of the present invention is to provide the preparation method of the double-deck essence lotion of this water and milk.

For this reason, the invention provides the double-deck essence lotion of a kind of water and milk, be made up of the component of following percentage by weight:

Ring five polydimethylsiloxane 3% ~ 8%, reed fragrant plant glue 2% ~ 4%, Fancol ID 2% ~ 4%, tetramethylolmethane four (thylhexoic acid) ester 2% ~ 4%, butanediol 1% ~ 4%, propylene glycol 2% ~ 4%, glycerin polyether-261% ~ 4%, glycerol 1% ~ 4%, avenabeta glucosan 1% ~ 4%, hamamelis water 1% ~ 4%, phenyl trimethicone 0.5% ~ 2%, phenoxyethanol 0.3%, PEG-6 caprylic/capric glyceride type 0.3% ~ 0.6%, thickening agent 0.1% ~ 0.3%, caprylyl glycol/Sensiva SC50 0.1%, methyl hydroxybenzoate 0.1%, butylated hydroxytoluene 0.1%, hyaluronate sodium 0.02% ~ 0.1%, colorant 0.00004%, excess water.

Preferably, described thickening agent includes but not limited to hydroxyethyl-cellulose.

Preferably, described caprylyl glycol/Sensiva SC50 is weight ratio is the caprylyl glycol of 7:3 and the mixture of Sensiva SC50.

Present invention also offers the preparation method of the double-deck essence lotion of described water and milk, comprise the following steps:

1) with butanediol moistening hyaluronate sodium, stirring, add water, propylene glycol, glycerol, glycerin polyether-26, PEG-6 caprylic/capric glyceride type, thickening agent, methyl hydroxybenzoate successively, be warming up to 80 DEG C, be incubated 20 minutes;

2) by ring five polydimethylsiloxane, tetramethylolmethane four (thylhexoic acid) ester, Fancol ID, phenyl trimethicone, butylated hydroxytoluene stirring and evenly mixing, 80 DEG C are warming up to;

3) evacuation, by step 2) mixture add step 1) mixture in, homogenizing 5 ~ 10min, stir cool to 60 DEG C;

4) add caprylyl glycol/Sensiva SC50 and phenoxyethanol, stir and be cooled to less than 45 DEG C;

5) add avenabeta glucosan, hamamelis water, reed fragrant plant glue and pre-dispersed colorant successively, stir.

The double-deck essence lotion technical advantage of water and milk of the present invention is as follows:

1, owing to adopting the double-deck system formula technique of emulsion, hydrogel essence, can use by shaking up slightly, after leaving standstill a period of time, lower floor is the essence lotion (aqueous layer) of transparent clarification, upper strata is soft fine and smooth as if milky oil breast (emulsion layer) of white clouds, demarcation line is clear, the beautiful novelty of outward appearance, is obviously different from the general dual layer product on market.

2, the present invention can be divided into two-layer at 48 hours completely, realizes fast hierarchical, and upper strata is essence lotion, and lower floor is the essence lotion of transparent clarification.

3, the present invention is using the hydrophilic emollient ester PEG-6 caprylic/capric glyceride of natural origin, glycerin polyether-26 as surfactant, form stable emulsion layer, evenly (girth is about 11.715 μm to emulsion droplet size, area is 10.921 μm 2, radius is about 1.865 μm), after standing considerable time, upper strata emulsion still can keep very good stability, there will not be the quality problem of other like product, such as oil content, oil-water separation phenomenon are separated out in upper strata.

4, the present invention with the addition of multiple firming and moisturizing and nourishes composition Hamamelis virginiana (HAMAMELISVIRGINIANA) water, hyaluronate sodium, does not need to apply astringent in advance, decreases skin protection step; By reed fragrant plant glue (glyceryl acrylate/acrylic copolymer (with) propylene glycol) cage structure hydrone is locked in wherein, slow releasing moisture in coating process, makes skin retain moisture while bringing lubrication skinfeel; Interpolation can activate epidermal growth factor, promote to allow skin more compact, high resilience by the beta glucan of collagen protein synthesis.

5, the present invention combines the performance of essence lotion and emulsion, has good skinfeel, and it is better to moisten the common essence lotion of Performance Ratio, and easilier than ordinary emulsion is absorbed, and therefore can substitute essence lotion and emulsion completely.

6, formula system of the present invention can add the active component of all kinds of aqueous phase or oil phase, and the flexibility ratio of formula, much larger than essence lotion, is suitable as all kinds of effect product substrate and applies.
