Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to make-up cosmetics, particularly eye make-up cosmetics.

The drawback of conventional makeup cosmetics is "makeup discoloration," which is the effect of human body secretions such as sweat, tears, and sebum on cosmetics, and the effects of rain, snow, pool water, seawater, etc. when using cosmetics. It is mainly caused by chemical effects such as the action of moisture due to the conditions of the place and the action of various ingredients in other cosmetics used together, and also the movement of the skin in the area where the blemish pigment is used, It solves various types of "makeup discoloration" mainly caused by physical effects such as stiffness due to clothing, etc.
The purpose is to obtain a makeup cosmetic with good makeup retention that does not contaminate clothing. Furthermore, conventional makeup cosmetics come in a wide variety of formulations, such as water-based, oil-based, emulsified, and powder-based. , make-up easily fades due to rain, etc., that is, water resistance is poor.

In addition, since oil-based products contain a large amount of lipophilic substances, they tend to be easily damaged by sebum or the oil content of cosmetics used in combination, that is, they have poor oil resistance. Emulsion type products do not have sufficient water resistance or oil resistance. Powder type is water resistant,
It has poor oil resistance, and makeup tends to come off due to movement of the skin at the site of use or being massaged by hands or clothing, that is, it has poor adhesion to the skin. Clothes are also easily contaminated. In order to solve the drawbacks of the above-mentioned makeup cosmetics, the present invention achieves the purpose by blending a certain type of oil-soluble cellulose derivative into a makeup product based mainly on oil-based and emulsified makeup makeup Q-salmon ingredients. To obtain a make-up cosmetic that has good water resistance, oil resistance, and adhesive properties, does not cause makeup deterioration, and has good makeup retention.

Conventional cosmetic ingredients include natural oil-soluble resins such as shellac and rosin, oil-soluble cellulose derivatives such as ethylcellulose, nitrocellulose, and cellulose acetate, alkyd resins, pinyl acetate resins, and polyesters. Resins, allylsulfonamide formaldehyde resins, and a wide variety of other water-soluble polymers have been used, but especially in the case of oil-soluble resins, they are not compatible with most of the components except for some solvent-based resins. However, it is difficult to say that the performance is good. The present invention eliminates the above-mentioned drawbacks by using ethyl hydroxyethyl cellulose (hereinafter abbreviated as EHEC), which is an oil-soluble cellulose derivative capable of forming a film, and provides an excellent makeup cosmetic.

The general formula of this EHEC is shown as -O of cellulose
Many of the H groups are substituted with ethoxyl groups or ethoxyshethoxyl groups, and the degree of substitution n is 2.4 to 2.4.
It is 2.8.

EHEC dissolves in polar waxes and oils, and also dissolves or swells in nonpolar chain hydrocarbons.

Those that do not dissolve can be dissolved transparently by adding a cosolvent such as ethanol or inpropyl alcohol. That is, EHEC has excellent compatibility with various substances. It also has the effect of acting as a thickener and preventing pigments from floating.

By incorporating 1 to 15% of this EHEC into makeup cosmetic ingredients, the purpose can be achieved.

In other words, the above characteristics of EHEC appear prominently in the product characteristics,
To obtain a make-up uniform agent that has excellent water resistance, oil resistance, and adhesion, and has good makeup retention without smearing the makeup. next,
An example of the present invention is shown. % is by weight. Example 1
Aishadu Crab Liquid Paraffin 60% Lanolin Derivatives 5% Ceresin Wax 10% EHEC
5% peace wax
5% pearl agent
10% blue world sheep blue
5% preservative, appropriate amount fragrance
Appropriate amount (manufacturing method) lanolin derivative, ceresin wax and peace wax 80%
A mixed solution of vertical liquid paraffin and EHEC is added to the solution uniformly heated and dissolved at ~90° C. and dispersed in a rope.

Then, by adding a pearl agent, blue violet blue, a preservative, and a fragrance, a blue cream eye shadow can be obtained. Example 2 Mascara Vertical Liquid Paraffin 50% Peace Wax 13 Power Lunauba Wax 3EHEC
IO La/Lin derivative
5 Sorbitan monostearate
2 ion exchange water
15 Carbon black 2 Preservatives Appropriate amount fragrance
Appropriate amount (manufacturing method) Peace wax, Lunauba wax, lanolin derivative, and sorbitan monostearate are heated and melted uniformly at 80 to 90°C, and a mixture of light liquid paraffin and EHEC at 70 qo is added and dispersed. A black cream mascara can be obtained by mixing carbon black and adding ion-exchanged water, preservatives and perfume.

A cream foundation can be obtained by adding, mixing, and cooling.

Appropriate amount (manufacturing method) Hydrocarbon wax, liquid paraffin, lanolin derivative, EHEC, and aluminum stearate are added to isoparaffin and dissolved and dispersed by heating to produce Red No. 201 and Red No. 202.
A liquid lipstick can be obtained by adding a pearl agent, dispersing the powder, adding a fragrance, and cooling the mixture.

Next, the amount of EHEC in the cream mascara formulation of Example 2, which is the Makeup Q salmon ingredient of the present invention, was adjusted to 2.5 to 15%.
．． Oil resistance between cream mascara containing 0% and cream mascara (conventional product) containing no EHEC. Comparative data regarding water resistance is shown in Figure 1.

In addition, the standard oil resistance and water resistance test methods are as follows.

Oil resistance and water resistance: A plate coated with cream mascara and dried is brought into contact with a test paper (test liquid: ○/W type emulsion is dropped in fixed amounts) a certain number of times (50 times), and the degree of transfer onto the test paper is compared. .

This test was repeated twice. (Formulation of 0/W type emulsion) Liquid paraffin 2% by weight Lanolin 5 piece wax
15 Glycerin monostearate (self-emulsifying type) 7 Water (ion exchange water) 53
Fragrance Appropriate amount of preservative
Appropriate amount In Figure 1, EH
A comparison of the cream mascara containing no EC (conventional product) and the cream mascara of the present invention containing 2.5 to 15.0% of each EHEC revealed that it clearly has excellent oil resistance and water resistance. Ta.

That is, the thinner the degree of transfer onto the test paper, the better the oil resistance and water resistance. The present invention is applicable to other foundations, eye make-up cosmetics such as eyebrows, eye shadows, eyeliners, and mascaras, body paints, nail enamels, lipsticks, hair colorants, and leg make-up cosmetics that affect the skin layer. It is widely applied to cosmetics and hair cosmetics.
