ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a lipcolor composition, particularly a lipcolor composition which less yields a dry feeling and an uneasy feeling with the passage of time, and whose color comes off less in friction with foods, drinks and so on.
BACKGROUND OF THE INVENTION
Lipcolors intrinsically function to make up lips, make a complexion better and make an expression brighter. Now, the increasing number of women have jobs and are working actively. Lipcolors play a very important role in makeup effects, compared to other makeup cosmetics, as a lipcolor alone can produce a bright expression even without a makeup base or other cosmetics. Accordingly, many working women tend to just arrange hair styles, pencil eyebrows and put on lipcolor. Then, busy women want to save time of fixing their lipcolor and are interested in durability of makeup effects more than ever. However, lipcolor compositions without an oil component and a coloring component were hardly conceivable from a point of view of satisfactory makeup effects and physical feelings. Accordingly, only limited means were allowed to enhance durability of the makeup effects. That is, most popular ways are to blend a large amount of a highly sticky or solid oil component or a coloring agent, or to blend a coloring substance having a dyeing property. There is a little elaborate method where a volatile component is blended and, upon its volatization, there remain only a powdery component, a solid oil component and a highly sticky oil component. Unfortunately, lipsticks produced in these methods are not durable to friction with foods, drinks and so on, loose their comfortable feeling of use and tend to discolor and cause a dry feeling with the passage of time. Thus, intrinsic functions of lipsticks are lost easily.
The present inventor proposed oily makeup cosmetics comprising divalent or trivalent metal or its salt or hydroxide, a water-soluble salt of alginic acid and an oil component (Japanese Patent Application Laid-Open Hei-1-96111). The oil components described there are olive oil, castor oil, jojoba oil, lanoline, vaseline, squalane, liquid paraffin, octyl dodecanol, glyceryl tri(caprylate/caprate) and silicone oil. The oily makeup cosmetics include a lipstick which comprises D. & C. Red No. 7 (C.I. No. 15850) (see the present specification, Comparison Example 4) and Aluminium lake of F.D. & C. Yellow No. 5 (C.I. No. 19140); candelilla wax, carnauba wax, vaseline, lanoline, octyl dodecanol and castor oil; calcium pantothenate, calcium lactate or calcium sulfate; and sodium alginate.
SUMMARY OF THE INVENTION
A purpose of the invention is to provide a lipcolor composition which less yields a dry feeling and an uneasy feeling with the passage of time and whose color comes off less in friction with foods, drinks and so on.
The present invention is a lipcolor composition comprising (a) at least one metal compound selected from the group consisting of salts of divalent and trivalent metals and hydroxides of divalent and trivalent metals, and (b) a water-soluble salt of alginic acid, characterized in that the composition further comprises (c) at least one red or orange lake color having a COONa or COOK group in its structure and (d) an oil component having appearance of liquid at a temperature of 20° C.
PREFERRED EMBODIMENTS OF THE INVENTION
The salts of divalent or trivalent metals used in the invention are known. Examples of the salts include calcium chloride, calcium carbonate, calcium lactate, calcium pantothenate, calcium sulfate, calcium citrate, calcium glycerophosphate, calcium gluconate, calcium hydrogenpyrophosphate, calcium biphosphate, calcium silicate, calcium stearate, calcium mesotartrate, calcium laurate, calcium acetate, aluminium sulfate, aluminium chloride, potassium alum, ferrous sulfate, ferric chloride, ferrous or ferric citrate, ferrous or ferric lactate, ferrous pyrophosphate, and sodium ferrous citrate. Water-insoluble salts such as barium sulfate are not preferred as they hardly react on lips. Hardly soluble salts such as calcium sulfate may be used. Preferred are calcium lactate, calcium pantothenate and calcium sulfate. The hydroxides of divalent or trivalent metals include calcium hydroxide, aluminium hydroxide and ferrous hydroxide.
The water-soluble salt of alginic acid used in the invention is known and includes sodium alginate, potassium alginate and ammonium alginate. The molecular weight of alginic acid is preferably 50,000 to 200,000, particularly 100,000 to 200,000, but not limited to these. The use of the higher molecular weight gives better results in the invention.
The red or orange colors having a COONa or COOK group in their structure are known. Those having a COONa group include D. & C. Red No. 28 (C.I. No. 45410); Rose bengal (C.I. No. 45440); D. & C. Red No. 22 (C.I. No. 45380); and D. & C. Orange No. 11 (C.I. No. 45425). Those having a COOK group include Eosine YSK (C.I. No. 45380); Phloxine BK (C.I. No. 45410); and Rose bengal K (C.I. No. 45440). The lakes of the colors used in the invention are lakes of the aforesaid colors with aluminium, barium, or zirconium the like.
The oil component which has appearance of liquid at a temperature of 20° C. includes monohydric alcohols having at least 16 carbon atoms; esters of monohydric alcohols having at least 3 carbon atoms or cholesterols with monobasic aliphatic carboxylic acids having at least 8 carbon atoms, adipic acid, oxystearic acid, succinic acid or malic acid; and esters of ethylene glycol, propylene glycol, neopentyl glycol, glycerin, diglycerin, trimethylol propane or pentaerythrytol with monobasic aliphatic carboxylic acids having at least 7 carbon atoms.
The monohydric alcohols having at least 16 carbon atoms, which have appearance of liquid at 20° C. and are used in the invention, are known and include isosteary alcohol, 2-octyl dodecanol, oleyl alcohol, 2-hexyl decanol and jojoba alcohol.
The ester of monohydric alcohols having at least 3 carbon atoms or cholesterols with monobasic aliphatic carboxylic acids having at least 8 carbon atoms, adipic acid, oxystearic acid, succinic acid or malic acid, which have appearance of liquid at 20° C. and are used in the invention, are known and include diisostearyl adipate, dioctyl adipate, isopropyl isostearate, cholesteryl isostearate, isononyl isononanoate, octyldodecyl erucate (ester of erucic acid), octyl oxystearate, cetyl octanoate, octyldodecyl oleate, oleyl oleate, dioctyl succinate, isocetyl stearate, isopropyl palmitate, octyldodecyl myristate, myristyl myristate, diisostearyl malate, decyl oleate, and octyldodecyl ricinoleate.
The esters of ethylene glycol, propylene glycol, neopentyl glycol, glycerin, diglycerin, trimethylol propane or pentaerythrytol with monobasic aliphatic carboxylic acids having at least 7 carbon atoms, which have appearance of liquid at 20° C. and are used in the invention, are known and include ethylene glycol octanoate, ethyleneglycol palmitate, propylene glycol isostearate, propylene glycol ricinoleate, propylene glycol di(caprylate/caprate), propylene glycol dicaprylate, propylene glycol dimyristate, propylene glycol dicaprate, neopentyl glycol dioctanoate, neopentyl glycol dicaprate, glyceryl triisostearate, glyceryl diisoastearate, glyceryl trioctanoate, glyceryl tri (caprylate/caprate), glyceryl ricinoleate, diglyceryl isostearate, diglyceryl diisostearate, diglyceryl triisostearate, trimethylol propane trioctanoate, trimethylol propane triisostearate, and pentaerythritol tetraoctanoate.
The lipcolor composition according to the invention may be in a form of solid, liquid or powder.
The lipcolor in the form of solid preferably contains (a) 0.1 to 5 parts by weight, particularly 0.5 to 3 parts by weight, of the salt or hydroxide of divalent or trivalent metal, (b) 0.1 to 5 parts by weight, particularly 0.5 to 3 parts by weight, of the water-soluble salt of alginic acid, (c) 3 to 20 parts by weight, particularly 3 to 10 parts by weight, of the red or orange lake color having a COONa or COOK group in its structure, and (d) 1
