Description

The composition of oil-in-water emulsion form

The present invention relates to the compositions of oil-in-water emulsion form, more particularly, it relates to improved optics effect The composition of fruit, especially blur effect.

The prior art

Due to being especially and using more comfortably（Flexibility, palliative etc.）Relevant a variety of causes, currently used for handling angle egg The composition of white material, especially skin is usually the water packet being made of by dispersion discontinuous phase aqueous dispersion continuous phase and oiliness Oil（O/W）The lotion of type disperses continuous phase and the aqueous Water-In-Oil formed by dispersion discontinuous phase by oiliness（W/O）Type Lotion form.

O/W lotions are the most popular one kind of cosmetic field because they include water phase as external phase, this enables them When being applied on skin with more pure and fresh than W/O lotion, less greasy and slimmer and more graceful feeling.

It is conventionally known to prepare huge drop lotion（giant-drop emulsion）To obtain good comfort.

Document FR-2 843 695 describes the amphipathic polymerization containing non-crosslinked 2- acrylamide-2-methylpro panesulfonic acids The O/W lotions of object and oil content more than 40 weight %.But such oil phase amount results in oil during being applied to skin Greasy and shinny effect, user can not receive this.In addition, known by FR 2 927 252 includes amphipathic nature polyalcohol such as 2- The O/W lotions of acrylamide-2-methylpro panesulfonic acid derivative and oil content less than 30%.

On the other hand, one of the final purpose of cosmetic composition is to reduce the appearance of flaw on skin, on skin Microgroove, wrinkle and pore.This may be implemented by composition of the preparation with good optical effect, especially blur effect Purpose.

Many trials have been carried out thus.

It is known that being constituted by using silicone elastomer combination particle for reducing microgroove, wrinkle in cosmetic field The product that line or pore occur.For example, US2005/0100568 discloses a kind of composition, it includes cross linking polysiloxane elasticity The combination of body, light diffusing particles in cosmetically acceptable carrier.

But the above-mentioned prior art has not been able to obtain the composition with all above-mentioned properties.

Therefore oil-in-water emulsion is needed, especially contains the lotion of " huge " drop, with slim and graceful fluid quality, and also has There are improved optical effect, especially blur effect.

Also need to it is with sufficient stability, i.e., through when the above-mentioned composition stablized.

Summary of the invention

It has been found by the present inventors that being included in the oil phase in continuous aqueous phase by preparation, and it include 2- acrylamido -2- methyl Propane sulfonic acid polymer（It is one or more）, organopolysiloxane elastomers（It is one or more）Including talcum（It is one or more） With the oil-in-water emulsion of two kinds of delustring fillers of cellulose bead, such needs may be implemented.

The present invention relates to the compositions of the oil-in-water emulsion form of the oil phase included in continuous aqueous phase as a result, and include：

a）At least one crosslinked poly- (2- acrylamide-2-methylpro panesulfonic acids) polymer, at least 90% is neutralized；

b）At least one organopolysiloxane elastomers；With

c）At least two delustering agents, including at least one talcum and cellulose bead

The bead of the wherein described lotion has 15 to 500 microns of average-size, and the oil phase is with the small of composition total weight Exist in the amount of 35 weight %.

The composition of the present invention is advantageous in many aspects.

First, composition of the invention has improved optical effect.Particularly, which refers to blur effect. " blur effect " is intended to refer to reduce skin blemishes（Such as microgroove, wrinkle and pore）The effect of appearance.

The instrument measurements of the transmissivity of the composition of blur effect through the invention, mist degree and opacity characterize.

Particularly, the machine Haze-gard Plus that are sold by BYK companies measure transmissivity（TH）And mist degree.

By using 4340 Automatic Film Applicator of machine Elcometer in hyaline membrane（BYK - 2 mil #2871 of Byko-charts transparent polyesters）On prepare thickness and be somebody's turn to do for the film of the composition of 25 microns of the present invention It measures.

The opacity of the composition of the present invention passes through the device Chromameter that is produced by Konica Minolta companies CR-400 is measured, and obtains L* values.

Opacity value is calculated by following formula：

(L*_Black+16) ^3/ (L*_White+16) ^3 ×100。

More particularly, by using 4340 Automatic Film Applicator of machine Elcometer in black/white Card（Erichsen Typ24/5）On prepare thickness and carry out the measurement for the films of 50 microns of compositions containing the present invention.

For the purpose of the present invention, the composition has the transmissivity more than or equal to 90（TH）, it is greater than or equal to 85, is preferably big In or equal to 90 mist degree, and the opacity less than or equal to 8.

In addition, the present invention composition through when stablize.

If in different temperatures（T=4℃、T_{Room temperature}, 40 DEG C and 45 DEG C）Lower storage does not observe its macroscopic view or micro- after 2 months See appearance and its physicochemical characteristics（Drop size, pH, viscosity）Variation, then lotion is stable.

In addition, the composition itself provides comfort to skin, as flexibility, palliative, aquation and Pure and fresh degree.

The invention further relates to make up and/or nurse keratin material, especially human skin and lip according to another aspect, Method, include the steps that it is at least one to the keratin material apply the present invention composition.

Another aspect of the present invention is related to the purposes in terms of flaw appearance of the above-mentioned composition on reducing keratin material, The defect includes microgroove, wrinkle and pore.

For the purpose of the present invention, term " keratin material " is intended to skin, mucous membrane（Such as lip）, nail.According to this hair Bright, special consideration should be given to skins and lip, especially skin of face.

According to the present invention, " granularity of delustring filler " refers to volume median diameter, passes through Brookhaven BI-90 light Photon correlation spectrometer measures.

Detailed appraisal procedure is described below.
