(conventional art)
The coloring agent (as pigment and dyestuff) that is used for lipophilic solid cosmetic composition is mainly used in cosmetic purpose, for example lip pomade, eye shadow, rouge and foundation cream; Think that skin provides color.Here employed coloring agent not only should provide tempting color, and can also satisfy the general characteristic of making make-up composition.That is to say that this class feature comprises the outward appearance uniformity, good coloring and use the long-lasting stable color in back when using.
Disclose according to GB patent 1,173,743, contain the dyestuff that is insoluble to oil in the cosmetics or the mixture that is insoluble to oil and is dissolved in the dyestuff of oil is benefited.
In addition, the lip pomade and the lipophile cosmetics of oil base dye mixture or oil base dyestuff and acid dye composition have also been disclosed in this technical field.
JP publication S63-119405 has disclosed a kind of transparent Solic cosmetic, it has the good transparency, appearance stability and excellent practicality and dyestuff dissolubility thereof, it is characterized in that containing the partial ester of 12-hydroxy stearic acid, rosiny polyol ester and polyhydric alcohol and branched chain fatty acid, perhaps the ester of polyhydric alcohol and unsaturated fatty acid.
JP publication H1-90110 has disclosed a kind of transparent Solic cosmetic, it has the stability and the first-class practicality and the dye stability of the good transparency, appearance, its characteristics are the partial ester of amide containing resin, rosin pentaerythritol ester, polyglycereol and side chain fat acid, the perhaps ester of polyglycereol and unsaturated fatty acid.
JP publication H1-287011 discloses, a kind of emulsifying lip pomade, and it has vivid color, contains water solublity mineral hargil, water and fluorescence class dyestuff.
JP publication H3-86808 has disclosed a kind of lip pomade, it has excellent practicality, as good color representation, spreadability, tack, long-term persistence, good surface appearance and stability, the ester compounds of forming by oxyacid and aliphatic alcohol that contains solid carbon hydrogen compound, the 15-16% of 13-21%, the liquid of 20-65% or pasty state Hydrocarbon, and oil base dyestuff.
JP publication H3-90013 has disclosed a kind of lip pomade, it has excellent practicality, as good color representation, spreadability, tack, long-term persistence, good surface appearance and stability contain the ester compounds of being made up of polyhydric alcohol and aliphatic alcohol of solid carbon hydrogen compound, the 15-60% of 13-21%, liquid-type pasty state Hydrocarbon and the oil base dyestuff of 20-65%.
JP publication H3-236307 has disclosed a kind of lipophile cosmetics, and its not diaphoresis has the high chroma color, it is characterized in that containing 0.01-30wt% gama-alumina (a certain relative surface area of tool), and the oil base dyestuff of 0.01-10wt%.
Yet acid stain is exposed to easily decolouring under the atmospheric humidity, can cause the variation of color itself.For cosmetics (as lip pomade), nondiscoloration preferably.Like this, with regard to conventional art, lipophile cosmetics (as the cream lip) tendency that contains acid stain is used for dead color, because dark-coloured decolouring can be so unobvious.
At this, by containing a kind of acid stain of tool water-soluble organic acid, obtained a kind of lipophilic solid cosmetic composition, it has good coloring, and long-term persistence and good color stability are promptly passed in time and are decoloured few.
Simultaneously, consider safety, need be with a spot of dyestuff coloring effect that offers the best.As everyone knows, dyestuff is difficult to dissolve in the lipophilic solid cosmetic composition equably, because it has the trend with other lipophile component separating, therefore needs its content as much as possible little.
At this, by also containing a kind of oil base dyestuff, obtained a kind of lipophilic solid cosmetic composition, it has good coloring, long-term persistence, good color stability and the outward appearance uniformity of improvement.The total amount of dyestuff is few, and tone range is wide.
(purpose of the present invention)
The object of the present invention is to provide a kind of lipophilic solid cosmetic composition, it has good coloring, long-term persistence and good color stability.
The present invention also aims to provide a kind of lipophilic solid cosmetic composition, it uses a spot of dyestuff but to have same effect.
The present invention also aims to provide a kind of lipophilic solid cosmetic composition, its outward appearance uniformity and tone range with improvement is wide.
(detailed description of the present invention)
The present invention relates to a kind of lipophilic solid cosmetic composition, it contains by weight: (a) acid stain of 0.01-1%; (b) 0.01-0.5% has the water-soluble organic acid of one or more functional groups; And the oil base dyestuff that is preferably 0.01-2%.
Dyestuff and organic acid
Make-up composition of the present invention contains the acid stain of 0.01-1wt%, and preferred content is 0.01-0.25wt%.The acid stain that uses among the present invention is that those are enough to be used safely in the acid stain in the cosmetics, for example D﹠amp; C Red
#28 (according to the Red of Japanese health benefit portion (to call MHW in the following text) rules and regulations
#104-(1)), D﹠amp; C Red
#6 (according to the Red of MHW rules and regulations
#201), FD﹠amp; C Yellow
#5 (according to the Yellow of MHW rules and regulations
#4) and FD﹠amp; C Yellow
#6 ((according to the Yellow of MHW rules and regulations
#5)).But the acid stain former state adds in the make-up composition, or adds as the mixture with fatty acid ester.
Make-up composition of the present invention contains the water-soluble organic acid with one or more functional groups of 0.01-0.5wt%, and preferred content is 0.05-0.1wt%.The example of water-soluble organic acid is a citric acid, anhydrous citric acid, lactic acid, tartaric acid and malic acid.
Can decolour though people generally know acid stain, itself and organic acid be mixed mutually can improve its coloring and the stability of color in time.As long as there is a small amount of organic acid just can observe this effect, when organic acid content is at least 0.5 times (weight) of acid stain, can be observed remarkable result.
Make-up composition of the present invention also can contain the oil base dyestuff of 0.01-2wt%, and preferred content is 0.01-0.5wt%.The oil base dyestuff that uses among the present invention is that those are enough to be used safely in the oil base dyestuff in the cosmetics, as D﹠amp; C Red
#21 (according to the Red of MHW rules and regulations
#223), D﹠amp; C Red
#27 (according to the Red of MHW rules and regulations
#218) and D﹠amp; C Or-ange
#5 (according to the Orange of MHW rules and regulations
#201).In the present invention, add the oil base dyestuff, compare, only use more a spot of dyestuff just can obtain identical coloring effect with only adding acid stain.From angle to skin safety and product stability, add article and be necessary for minimum flow.In addition, the combination of dyestuff has enlarged the kind of tone.But oil base dyestuff former state adds in the make-up composition, perhaps adds as the mixture with fatty acid ester, and acid stain is also like this.
Solvent
In the present invention, organic acid can be incorporated in the make-up composition, be about to it and be dissolved in the 0.1-5wt% that accounts for make-up composition, preferred 0.5-3wt% is most preferably in the solvent of 0.7-1.5wt%.Solvent can be selected from water, have the monohydric alcohol and the polyhydric alcohol of 1-6 carbon atom.The example of solvent is water, ethanol, isopropyl alcohol, glycerol, two glycerol, triglycerin, ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, 1,3 butylene glycol and 1, the 4-butanediol.By adding the organic acid as solvent solution, organic acid can be evenly dispersed in the make-up composition, sees it is preferred from the angle of method.Find also that in addition some combination of dyestuff and solvent can improve the stability of color.Moreover because some polyhydric alcohol has good adhesion to skin, the combination of itself and dyestuff can improve coloring.The selection of type of solvent to consider its in make-up composition with the intermiscibility of other composition, also to consider the needs of resultant product simultaneously.
