Description

Water-in-oil type lip makeup composition containing natural pigments}

The present invention relates to a water-in-oil type lip makeup composition containing natural pigments, and more particularly, in a water-in-oil type emulsion state (a) natural pigments, (b) polyols, (c) metal ion sequestrants, (d) acidity regulators By containing (e) purified water and (f) surfactant, the present invention relates to a water-in-oil type lip makeup composition which enables the use of various natural pigments and exhibits excellent color expression, moisturizing feeling, refreshing feeling and non-stickiness.

Since lip makeup products come into the body with food, there is a greater need for safety than other cosmetics. In addition, the demand for natural pigments is increasing in the situation that the safety problems for the tar-based pigments, which are synthetic pigments, continue to emerge.

Conventional lip cosmetics, especially in the case of a liquid lip makeup composition can be said to be an anhydrous oil-dispersion formulation. Its components include, first, solid ingredients that maintain the appearance of the lip cosmetic composition by increasing the hardness such as candelillanab, ceresin, carnauba wax, paraffin, wax, braze, beeswax, microcrystalline lead and polyethylene. Secondly, a variety of liquid oils such as squalane, lanolin oils, lanolin derivatives, plant-derived oils, synthetic ester oils and silicone oils; third, high viscosity polybutenes, polyisobutenes, hydrogenated polybutenes and hydrogenated High viscosity polymers such as hydrocarbon polymers such as polyisobutene, high viscosity esters, high viscosity ethers, high viscosity silicones and high viscosity alkylsilicones, urethanes and urethane silicones, and fourth pigment components such as organic pigments, inorganic pigments and iron pigments, and the like. Others include potent ingredients such as antioxidants, preservatives, fragrances and other extracts. Minutes are included.

The liquid lip makeup composition of the oily base is prepared by a method of uniformly dispersing the pigment and the colorant after melting at high temperature. This general gloss lip makeup composition is characterized by containing a large amount of polymer, containing a large amount of such polymer has the advantage of excellent gloss, but high viscosity gives the coating a thick, stuffy and sticky lips. In addition, the liquid type has the disadvantage that the oil component spreads between the wrinkles of the outer lip, the makeup is dirty and the color is blurred.

There are several problems with the current technology to make formulations that represent makeup in natural colors. Most natural pigments are composed of anthocyanin-based hydrophilic substances. However, since the general lip makeup composition is anhydrous, color pigments are low and unstable when natural pigments are used, so the pigments are easily separated from the formulation. In addition, natural pigments have a disadvantage in that they are easily changed by pH, heat, and sunlight. However, in the anhydrous type, there is a problem in stability because it is not easy to control them.

Lip makeup compositions using natural pigments are disclosed in Korean Patent Publication No. 10-1998-0071875. However, the composition can be used only in the oil-soluble or powder form by applying to an anhydrous type, but when using a water-soluble pigment, there is a stability problem and can not obtain the proper color development can not meet the physical properties required as color cosmetics . In particular, the range of the pigment | dye which can be applied to an anhydrous type | mold lacks a moisturizing feeling, a refreshing feeling, a non-sticky feeling, etc., and is limited.

Water-in-oil type lip makeup compositions include Japanese Patent Application Laid-Open Nos. Hei 1-168607, Hei 7-267826 and Korea Patent Publication No. 10-2007-0111001. In the lip makeup composition using a water-in-oil emulsion, only a synthetic pigment was used as a pigment. Although it improves the feeling through water-in-oil type emulsion, the safety controversy due to artificial pigment still remains a problem.

Therefore, the present inventors have studied to find a lip makeup composition that is safe for the human body and excellent in color expression using natural pigments. A water-in-oil type lip makeup composition containing a modifier, (e) purified water and (f) surfactants can capture natural pigments in the water phase to ensure stability and exhibit excellent color expression, moisturizing, refreshing and non-sticky feeling And the present invention was completed.

Accordingly, it is an object of the present invention to provide a water-in-oil type lip makeup composition containing natural pigments and safe for the human body.

In order to achieve the above object, the present invention provides a water-in-oil type containing (a) natural dyes, (b) polyols, (c) metal ion sequestrants, (d) acidity regulators, (e) purified water and (f) surfactants. It provides a lip makeup composition.

The water-in-oil type lip makeup composition of the present invention can use various water-soluble natural pigments by stabilizing natural dyes, which could not be used due to stability, color expression, etc. in the conventional anhydrous type through water-in-oil type formulations, and due to artificial coloring The safety problem can be solved. In addition, the lip makeup composition according to the present invention improved the stability, moisturizing feeling, refreshing feeling and non-sticky feeling was possible to fresh lip makeup.

The present invention provides a water-in-oil type lip makeup composition containing (a) natural dyes, (b) polyols, (c) metal ion sequestrants, (d) acidity regulators, (e) purified water and (f) surfactants.

Natural dye of the present invention (a) is extracted from the pigment part from the natural material can be used all pigments derived from nature, specific examples are safflower pigment, sweet potato pigment, gardenia pigment, turmeric pigment, red yeast pigment, beet pigment, Purple pigment, paprika pigment and red radish pigment. Natural pigments may be dissolved in polyols, purified water, ester oils, polymers or waxes. The natural pigment is preferably contained in 0.01 to 20% by weight based on the total weight of the composition. If the content is less than 0.01% by weight, the cosmetic effect is insufficient, if the content exceeds 20% by weight pigmentation occurs and the safety and stability problems occur.

The polyol (b) of the present invention is, for example, glycerin, butylene glycol, propylene glycol, and the like, which are included to impart a moisturizing feeling and a non-sticky feeling. The polyol is preferably contained in 1 to 20% by weight based on the total weight of the composition. If the content is less than 1% by weight is less moisturizing effect, if it exceeds 20% by weight is because the emulsion stability is lowered and a feeling of stickiness occurs.

(C) Metal ion sequestrant of the present invention is a component used for improving the stability of the emulsion formulation. Most natural pigments are unstable, unlike synthetic pigments that are rake-treated with metal ions, and if they have metal ions, their stability is significantly lowered. Metal ion sequestering agents usable in the present invention include disodium EDTA, hydroxyethylidene diphosphonate, trisodium phosphate and the like. The metal ion sequestrant is contained in an amount of 0.001 to 1% by weight based on the total weight of the composition. If the content is less than 0.001% by weight, the metal ion sequestration effect is weak, and if it exceeds 1% by weight, the excess metal ion sequestrant causes problems in stability.

The acidity regulator (d) of the present invention is a component that controls the acidity of the water phase part. Natural pigments have an appropriate pH range for each pigment, so stability falls outside the range and, in severe cases, even colors. Therefore, it is preferable to adjust the pH to a stable pH range using a buffer solution such as citric acid / sodium citrate or salicylic acid / sodium salicylate, and the content of the acidity regulator may be used in an amount to determine the proper pH of the composition. Acidity regulator of the present invention is contained in 0.0001 to 3% by weight based on the total weight of the composition. If the content is less than 0.0001% by weight, the pH control effect is insignificant, and if the content exceeds 3% by weight, there is a problem in stability and safety.

(E) Purified water of this invention is a component which gives a refreshing feeling and freshness. The purified water is preferably contained in an amount of 1 to 50% by weight, more preferably 10 to 30% by weight based on the total weight of the composition because it affects stability and usability depending on the change in content.

As the (f) surfactant of the present invention, an ester surfactant or a silicone surfactant may be used as the lipophilic surfactant. The surfactant is contained at 0.01 to 5% by weight based on the total weight of the composition. If the content is less than 0.01% by weight, the emulsion cannot be stabilized. If the content is more than 5% by weight, the feeling of use is deteriorated due to the excessive surfactant.

The ester surfactants include sorbitan monoisostearate, sorbitan diisostearate, sorbitan sesquiisostearate, sorbitan monooleate, sorbitan dioleate, sorbitan sesquioleate, and glyceryl mono Isostearate, glyceryl diisostearate, glyceryl sesquiisostearate, glyceryl monooleate, glyceryl dioleate, glyceryl sesquioleate, diglyceryl diisostearate, diglyceryl diol Oleate, diglycerine monoisostearyl ether, diglycerine diisostearyl ether, and mixtures thereof.
