2. false eyelashes are taken out, observe mascara residual condition in water, and take pictures.

3. residual fewer, water proofing property is better

Residual description Scoring Almost do not remain 5 A small amount of strip remains 4 2-3 bulk is residual 3 3-5 bulk is residual 2 More than 5 pieces block residual 1

In all oil system embodiment and comparative example as follows

All oil system Recipe:

1. under room temperature, trimethyl silicane alcoxyl base esters of silicon acis is dispersed in A phase

2. mixed C phase also homogenizing A, C phase

3. 95 DEG C add B phase mix homogeneously, stir cooling.

rG90, the mixture (wherein carrier fluid is Fancol ID) of vinyl-dimethyl base/trimethylsiloxysilicates stearyl dimethicone cross linked polymer and Fancol ID, it is a kind of silicone elastomer gel, the content of elastomer copolymer is about 20 % by weight, viscosity is about 30,000mPa.s, is provided by Wacker Chemical Co., Ltd.

rG100, the mixture (wherein carrier fluid is ring penta dimethyl siloxane) of polydimethylsiloxane/vinyl trimethyl siloxy esters of silicon acis cross linked polymer and ring penta dimethyl siloxane, it is a kind of silicone elastomer gel, elastomer copolymer content is about 20 % by weight, viscosity is about 120,000mPa.s, is provided by Wacker Chemical Co., Ltd.

Obtain test result evaluation as follows

Embodiment 1-3 have passed stability test

Add silicone elastomer gel in product system viscosity is not had a significant impact.Product expression containing this gel goes out the outward appearance of viscoelastic and effectively wraps up eyelashes, improves the dense degree of mascara.The comparative example 1 of silicones as film former is only added in contrast, and when silicone elastomer gel addition is more than 1%, dense degree has obvious lifting.This gel makes its radian along with brush roll up instantaneously to stick up eyelashes as film former sizing eyelashes while brushing.Addition is higher, and volume sticks up more obvious.Meanwhile, silicone elastomer gel and water immiscible, after the volatilization of low-molecular-weight oil preparation, this gel is connected to form hydrophobic membrane by organic for whole system, contributes to improving product water proofing property.

Use another kind of silicone elastomer gel rG100 be used for complete oily mascara system (embodiment 3), dense degree and volume set-back better.

In comparative example 2, do not use silicone elastomer gel, increase by 2% Cera Flava consumption.By comparative example 2 and use 2% the Contrast on effect of the embodiment 3 of RG100, data are as follows.Cera Flava is dense setting agent important in mascara, but consumption is too much, and system is thickness too, and molding effect is bad.When Cera Flava with to replace in proportion when RG100 compares, the dense degree of embodiment 3 mascara and the volume that with the addition of silicone elastomer gel stick up better.

Water-in-oil system embodiment and comparative example as follows

Oil packed water formulation technique:

1. under room temperature, trimethyl silicane alcoxyl base esters of silicon acis is dispersed in A phase

2. mixed C is added to A phase and homogenizing

3. 95 DEG C are heated B phases and add the mixture of A, C phase

4. mix D1 respectively, D3 phase adds the D2 phase of premix again, mix homogeneously

5., in stirring, D phase slowly adds the mixture of A, B, C phase, and emulsifying is even

6. slowly cooling is stirred to

? Comparative example 3 Embodiment 4 Embodiment 6 Dense density scores 2 4 3 Volume set-back 22 43 35 The scoring of volume set-back 3 5 5 Water proofing property (cotton pads method) 4 5 4 Water proofing property (infusion method) 4 5 5

Use the polymer substituted for silicon resin of 1-eicosane and l-vinyl-2-pyrrolidone as film former, the comparative example 3 obtained with the combination of silicone elastomer gel, its dense density scores is 2, and the scoring of volume set-back is 3, and water proofing property is 4.Successful is lower than embodiment 4 and 6, and illustrate that the combination of silicone elastomer gel and silicones obtains more excellent dense degree and rolls up set-back, this is surprising.

Dow Corning9041, the mixture of polydimethylsiloxane cross-linked copolymer and polydimethylsiloxane, viscosity between 300,000-500,000cP, non-volatile content 100%.Wherein there are the polysiloxanes containing Si-H key and 1, the silicone elastomer (silicone elastomer accounts for product 10-30 % by weight) that the cross-linking reaction of 5 hexadienes obtains, the polydimethylsiloxane silicone oil of its carrier fluid to be Dow Corning Corporation's marque be PMX-200 is also a kind of silicone elastomer gel.The embodiment 7 prepared with it also has the dense degree suitable with embodiment 4 and 6 and rolls up set-back.

Embodiment 4-7 have passed stability test.

Oil-in-water system embodiment and comparative example as follows

Oil-in-water Recipe:

1) A-1 phase is mixed at 60 DEG C

2) room temperature mixing A-2 phase be mixed into A-1 phase

3) C is added in the A phase of mix homogeneously and progressively adds F phase again, then is mixed into B phase homogenizing

4) be pre-mixed D phase 95 DEG C and add E phase

5) D, E phase is slowly added at 95 DEG C the mixture of A, B, C, F phase

6) emulsifying 10 minutes, pours into packaging material

The test result of comparative example 4 (not adding the system of silicone elastomer gel) and embodiment 8 is as following table.Visible in oil-in-water system, silicone elastomer gel also can significantly improve dense degree and the volume set-back of product.Embodiment 8 have passed stability test.
