Abstract
The present invention relates to the foundation cream premix changed colour from deep to shallow, foundation compositions and preparation method thereof.The powder premix includes titanium dioxide and inorganic pigment, and the titanium dioxide is by using (Cn'H2n'+1)aSi(OCmH2m+1)4‑a(n' is integer and n' >=1, m is 1 or 2, a are integer and 3 >=a >=1) be surface-treated；The inorganic pigment, which passes through to use, includes (CpH2p+1)bSi(OCqH2q+1)4‑b(p is integer and p >=1, q is 1 or 2, b are integer and 3 >=b >=composite treating agent 1) with dimethyl silicone polymer (n is integer and n >=1) is surface-treated.The invention further relates to the preparation method comprising the premix and include the foundation compositions of the premix.The foundation compositions of the present invention have the advantages that color changeable effect is controllable and fast, degree of wetting is high, strong covering power, color are various, safe and harmless and simple production process.
Description
Technical field
The present invention relates to cosmetic field, and in particular to a kind of foundation cream premix changed colour from deep to shallow, comprising the foundation cream
The foundation compositions of premix and their preparation method.
Background technology
Foundation cream such as vanishing cream/liquid is a kind of very important cosmetics category, is also the base for the dressing effect accomplished
Plinth.Generally according to user's colour of skin depth, there is provided the foundation cream of different colours (such as deep colour of skin, the shallow colour of skin) for cosmetics producer.It is general
The appearance color of logical vanishing cream and Shi Jishiyong color are basically identical.
In order to create the visual effect of novelty, the purpose for attracting consumer is reached, new color-change powder is occurred in that in recent years
Bottom.Discoloration is typically that during smearing, lotion is converted into deeper color (such as deep skin from light (such as canescence, white)
Color, the shallow colour of skin)；Or be converted into light (canescence, white) from dark (such as the deep colour of skin, the shallow colour of skin)；Again or from a kind of face
Color (such as light yellow) is converted into another color (such as peony).Common flour bottom can be played and cover skin fine wrinkles or the flaw
The effect of defect, there is obvious color changeable effect again, very novel, is well suited for building market concept and attracts consumer's eyeball.
, generally there is following three at the color-change powder bottom occurred in the market.
The first is cellulose adhering technique.The inorganic pigment that the technology is used in cosmetic foundation (is typically aoxidized
Iron oxide yellow, iron oxide red, iron oxide black etc.) surface, bonding medium is done with cellulose, ultra rme titanium dioxide is bonded.Preparation method
Closely folk tradition food：Lantern Festival (using fillings as core, the wet glutinous rice flour of surface adhesion).When in use, finger is passed through
Smearing, the titanium dioxide for sticking to surface of pigments departs under shearing force, and the Color development of pigment in itself comes out, foundation cream
Reach a process converted from white (or canescence) as the colour of skin (referring to Fig. 1).
Second of technology discoloration pearl essence technology.Refraction and scattering of the technology by pearl essence to light, reach discoloration
Effect.In use, being emulsified the pearl essence being wrapped in lotion, skin surface is coated on, the irradiation of light is touched, so that aobvious
The change of color is shown.
The third technology is to utilize acid-base indicator.The technology utilizes several acid-base indicators, in extraneous acid-base value (pH
Value) in the case of change, it may occur that it is prepared by the principle of color change.When in use, acid-base indicator touches skin (usual pH
It is worth for faintly acid), occur color change, so as to produce color changeable effect.
But all there is open defect in actual applications in the color-change powder bottom of above-mentioned three kinds of technologies.
Defect present in cellulose adhering technique includes following several respects：
(1) covering power is weak.The granular size (particle diameter) of inorganic pigment and be generally in the shape of it is stable (for example：Iron oxide red
Typically spherical, particle diameter is typically 0.3-0.5um；Iron oxide black is usually cube, and particle diameter is typically 0.3um or so), in order to
The adhesion package action reached, the particle diameter of titanium dioxide is as small as possible (conventional nano titanium oxide)；And in order to reach
Quick obvious color changeable effect, the titanium dioxide amount of inorganic pigment surface adhesion can not be too many, and adhesion layer can not be too thick.So difficult
To reach good covering power.
(2) color change is slow.Foundation cream when in use, has a smearing passage process, has wrapped up the iron oxide of titanium dioxide
Particle, is crushed under shearing force, and the iron oxide that the inside was wrapped in originally is revealed, and can just produce color changeable effect.Institute
With the speed of discoloration, depending on the size of external force, the firmness of the speed of smearing, and bonding particle.Slow soft smearing,
It is unfavorable for the broken of particle, is also just unfavorable for color changeable effect and shows.But use cosmetics, vanishing cream/liquid as a kind of face
Firmly quickly it can seldom be smeared repeatedly when in use, this just have impact on the color change and color changeable effect of the product.
(3) production technology is difficult to grasp.The firmness of cellulose bonding is a contradiction：Bond firmness too high, foundation cream
Frost/liquid is difficult to color changeable effect occur when in use；Bond firmness too low, will in vanishing cream/liquid production and pouring process
There is Particle Breakage, inorganic pigment is displayed too early.So in actual production, the color-change powder bottom of cellulose bonding is to production work
Skill has very high requirement：Agitating paddle can not scrape wall；Powder needs to soak in advance according to strict time and temperature；Emulsification times and
The quality of temperature must be controlled strictly ... product is difficult control
Defect present in the pearl essence technology that changes colour is included following aspects：
(1) color changeable effect is not obvious.Before smearing, discoloration pearl essence is hidden among lotion, is not contacted light, is seen not
To the color effect of pearl essence；After smearing, pearl essence is coated on skin surface, contacts light, shows color.This is this
The principle of color-change technology.But the color developing effect of pearl essence, compared with iron oxide color developing effect want it is weak a lot.And the master of vanishing cream
Act on and exactly cover flaw, adjust the colour of skin；For this point, pearl essence just seems unable to do what one wishes.
(2) luminous effect of pearl essence, is doomed unsuitable whole face and uses.The pearly-lustre that pearl essence naturally just has glittering is imitated
Really, it is local more suitable for use in eye shadow, lip gloss etc. in cosmetic process；It is to be used in entire surface and foundation cream is as the basis of cosmetic
Portion.If whole face all glitters, it is clear that can be very unnatural.
The defect existed using acid-base indicator is included following aspects：
(1) there was only color change effect, but foundation product can not be played should be effective.The mistake of only one of which color change
Journey.Covering flaw can not be played, the effect of the colour of skin is adjusted.
