Description

Lipstick containing pitaya pigment and preparation method thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to a lipstick containing pitaya pigment and a preparation method thereof.

Background

The lipstick made of plant pigments is ancient, and ancient people use extracts of mangrove, pomegranate, mountain flowers, sappan wood and other plants to mix with beef marrow, beewax and the like to prepare the lipstick, but the lipstick has defects in the aspects of color, quality guarantee, mildew resistance and the like, and is quickly replaced by the artificial synthetic pigment lipstick after 18 th century because the artificial pigment lipstick is bright in color, long in quality guarantee period and good in experience. However, in recent years, it has been found that plant pigments have the effects of nourishing skin, scavenging free radicals, resisting oxidation, delaying aging, regulating physiology and the like, and the ideas of green, environmental protection, ecology and the like are raised, so that the lipstick made of the plant pigments is gradually attracting attention. In 1993, Liu Jian Guo and Wu Chaoyuan disclose a patent of seaweed natural carotene cosmetics (publication No. CN1072083A), and a series of cosmetics such as lipstick, rouge, eye shadow, nail polish and sunscreen cream are produced by using seaweed natural pigment-carotene; in 1992, Liu Guo Rong, published the "Natural pigment lipstick" manufacturing method (publication No. CN1074601A), the natural pigment is derived from the mixture of fluid extract of plant red orchid, Sufang wood, red rose, etc. and refined oil such as peanut oil, camellia oil, rapeseed oil, cottonseed oil, etc., the lipstick does not have wax as the matrix, and is not called lipstick in the true sense; in 2006, Panyunfen proposed "a Natural pigment lipstick and its manufacturing method" (publication No. CN1977823A), which extracts pigment from Shang Lu fruit, directly smears it after high-temperature disinfection and sterilization, and does not mix with wax, grease, etc. to form solid matter, and it can not be called lipstick in the true sense; 2016, (CN 105534754A), discloses a preparation scheme for a colorful edible lipstick, which is prepared by mixing almond oil, pomegranate seed oil, olive oil, candelilla wax, bay wax, edible pigments (roselle red, sorghum red, cochineal red and mulberry red), plant squalane and natural vitamin E; 2016A lipstick containing natural components (CN 105796433A) is prepared from oleum Olivarum, flos Osmanthi Fragrantis essential oil, macadamia nut oil, carnauba wax, Cera flava, avocado oil ester, fructus Lycii haematochrome, herba Lycopi extract, herba Dianthi extract, allantoin, and vitamin E; in 2016, Lipman proposed "a 100% pure natural lipstick without castor oil, i.e. artificially synthesized material" (CN106309316.A), which is prepared by substituting palm oil and Aralia mandshurica kernel oil for castor oil, and mixing beeswax, coconut extract, Capsici fructus extract, astaxanthin, cochineal, etc.; in 2016, Zhang Zhong Zhi and junk head, published in blueberry lipstick and its preparation method (CN 106074317A), it was proposed to prepare blueberry lipstick by mixing blueberry anthocyanidin with lanolin, beeswax, ozokerite, vaseline, glyceryl monostearate, color paste, vitamin E and antiseptic. The natural plant pigments adopted for preparing the lipstick are not mentioned as pitaya pigments.

The pitaya belongs to the family of cactaceae, belongs to the family of Mexico in south America, is planted in Taiwan after the first 90 years, is transplanted into mainland China in Guangdong, Fujian, Hainan and other provinces, and comprises three types of white-pulp pitaya, red-pulp pitaya and yellow-pulp pitaya, wherein the red-pulp pitaya is rich in betanin and has bright red color, and accounts for more than 70% of the total yield. The dragon fruit has long fruit period, large fruit size and high pectin content, the deep processing of the dragon fruit mainly takes dragon fruit juice, fruit wine, dragon fruit beverage and the like at present, and the product is relatively single.

The red pulp dragon fruit contains natural pigment, the color of the red pulp dragon fruit is between that of scarlet and rose, the maximum absorption peak of the red pulp dragon fruit is near 430nm, the red pulp dragon fruit is bright rose, the color is unique, and the red pulp dragon fruit has more advantages than the natural pigment mentioned in the patent specification (for example, the carotene pigment is orange, the pigment extracted from the pepper is scarlet, and the medlar red pigment is dark red), so the development of the dragon fruit pigment into the raw material of the lipstick is a new direction for the high-value utilization of the resource utilization of the dragon fruit.

The dragon fruit pigment has obvious advantages in making lipstick: 1. the color is bright and is similar to the color of blood; 2. the dragon fruit pigment can be absorbed by the body, enters the body and is excreted through the kidney, so that no harm is caused to people; 3. scavenging free radicals in vivo; 4. reducing the damage of high frequency light rays such as ultraviolet rays to the skin. On the other hand, when the pitaya pigment is used for preparing lipstick, the technical problems to be overcome are as follows: 1. the pitaya pigment is water-soluble component, can be dissolved in polar organic solvent such as ethanol, and is insoluble in nonpolar components such as lipid and wax; 2. the coloring is light when the concentration is low, and the high-concentration and high-purity pigment solution needs to be extracted to prepare the lipstick with bright color; 3. the color is single, and the requirements of consumers on different colors of lipstick are difficult to meet; 4. easy to grow mildew and deteriorate.

The invention aims to provide a lipstick containing pitaya pigment and a preparation method thereof.

The technical scheme adopted by the invention is as follows:

a lipstick containing a pitaya pigment comprises a water phase component and an oil phase component, wherein the water phase component comprises a pitaya pigment extracting solution, an anionic emulsifier with an HLB (hydrophile-lipophile balance) value of 10-20 and a sweetening agent, and the oil phase component comprises a nonionic emulsifier with an HLB value of 10-15, liquid grease and a solid matrix.

Preferably, the dragon fruit pigment extracting solution is prepared by crushing red-pulp dragon fruit pulp, extracting pigment with an ethanol solution, filtering, centrifuging to obtain a clear solution, performing vacuum rotary evaporation on the clear solution, and removing ethanol at 80-85 ℃ at 80-160 r/min; then removing water at the temperature of 103-109 ℃ and under the condition of 80-160 r/min to obtain the nano-silver/nano-silver.

Preferably, the volume percentage concentration of the ethanol used for extracting the pitaya pigment is 70-99.5%.

The invention optimizes the extraction method of the dragon fruit. In the prior art, the extraction of the pigment of the pitaya is usually carried out by adopting the pitaya peel. However, the amount of pitaya peel is small and the pigment content in the peel is far less than the pigment content in the pulp. The invention utilizes the dragon fruit pulp to extract the pigment. The ethanol in the extracted ethanol extract is removed at 80-85 ℃, and then the water is removed at more than 100 ℃. The method is characterized in that the method comprises the following steps of removing free water in the dragon fruit pigment extracting solution as much as possible, leaving part of bound water, and correspondingly concentrating the pigment. The obtained pitaya pigment extracting solution has less impurities, high purity and high concentration, and the HLB value of the pitaya pigment extracting solution can be controlled within a fixed range, so that the preparation of the pitaya lipstick is facilitated.

According to the prior art, the method for extracting the pitaya pulp pigment by using the ethanol with the concentration of 35-45 percent is proposed in the research on the extraction and purification and the antioxidation and blood fat reduction of the red pulp pitaya pigment (Chenguanlin, research on the extraction and purification and the antioxidation and blood fat reduction of the red pulp pitaya pigment [ D ]. Guangdong college of pharmacy, 2013.). The obtained dragon fruit pigment extracting solution has more impurities and darker color, influences the HLB value of the dragon fruit pigment extracting solution, and can easily cause the demulsification phenomenon of the dragon fruit lipstick if the dragon fruit lipstick is prepared according to the formula provided by the invention.

Preferably, the HLB value of the anionic emulsifier is 10-20. The anionic emulsifier comprises PEG-7 sodium olive oil carboxylate, alkyl aryl sulfonate, sodium fatty alcohol polyoxyethylene ether sulfate, triethanolamine oleate, sodium oleate and potassium oleate.

The nonionic emulsifier comprises polyoxyethylene sorbitan monooleate, fatty alcohol polyoxyethylene ether, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan trioleate, polyoxyethylene aromatic ether and polyoxyethylene castor oil.

The anionic emulsifiers and nonionic emulsifiers are preferably obtained. According to the invention, an emulsification system with HLB value of 10-20 can be obtained, and polar components are uniformly dispersed in nonpolar oil and wax.

Preferably, the sweetener is sodium cyclamate, or sodium cyclamate.

The sodium cyclamate is a sweet additive which is most widely applied in food, the sweetness of the sodium cyclamate is 40-50 times that of cane sugar, the daily intake of each kilogram of body weight of a person is not more than 2.5 milligrams, and the sodium cyclamate is safe and environment-friendly. The object of the present invention is to produce an edible lipstick that does not feel unpleasant odors when a person inadvertently eats the lipstick, while being harmless to the body.

Preferably, in the aqueous phase component, the ratio of anionic emulsifier: a sweetening agent: the mass ratio of the pitaya pigment extracting solution is (6-9): (0.8-1.2): (180-260).

Preferably, the aqueous phase component further comprises a food grade colorant, the food grade colorant being at least one of curcumin, capsanthin, betalain or beta-carotene.

Wherein, the compounding of the pitaya pigment and the beta-carrot pigment can lead the color of the lipstick to be yellow, and the orange lipstick can be obtained by increasing the proportion of the beta-carrot pigment; the red color of the red pepper, the beet red pigment and the dragon fruit pigment can be orange red.

Preferably, in the aqueous phase component, the ratio of anionic emulsifier: a sweetening agent: food-grade colorant: the mass ratio of the pitaya pigment extracting solution is (6-9): (0.8-1.2): (8-10): (180-260).

The above proportions are primarily for color and taste and texture, and allow the pitaya lipstick to form a solid and be poured into a mold to form a paste. The color is the best texture and the best color ratio which are obtained by the research and development of the applicant and the trial and experiment of a plurality of times.

Preferably, the dosage of the nonionic emulsifier is 2-6 times of that of the anionic emulsifier in terms of mass ratio.

This is the best ratio the applicant has obtained during trial and error. The addition of a small amount of the nonionic emulsifier can cause poor emulsification effect, such as easy demulsification (oil-water separation) or poor lipstick color, and the addition of a small amount of the emulsifier causes poor color effect due to insufficient oil-water fusion degree.

Preferably, the solid matrix is at least one of carnauba wax, beeswax, and candelilla wax. Waxes belong to the class of hydrocarbons (hydrocarbons). Among them, carnauba wax, beeswax, candelilla wax and the like having a high melting point are called "wax", and are also used as cosmetic raw materials. The oil is generally glycerin fatty acid.

Preferably, the dosage of the solid matrix is 38-40% of the dosage of the dragon fruit pigment extracting solution, and the solid matrix is calculated according to the mass percentage.

This is the optimum ratio obtained by trial and error, which makes the lipstick moderate in color degree and moderate in hardness. If the solid matrix is added too much, the lipstick is too hard and cannot be painted out, and the lipstick looks like a crayon. If less, it will result in no formation of solid lipstick.

Preferably, the liquid oil is 29-33% of the dragon fruit pigment extracting solution by mass percent.

This is the optimum ratio found by trial and error. Less liquid oil is added, and the lipstick is not moist enough; if too much, it is too greasy and the paste may not form a solid.

Preferably, the liquid oil is at least one of palm oil, cotton seed oil, grape seed oil, olive oil and aromatic essential oil.

Preferably, the liquid oil is a mixture of cottonseed oil and aromatic essential oil, wherein the mass ratio of the cottonseed oil to the aromatic essential oil is (16-24): (1-2).

Preferably, the oil phase component further comprises a food grade preservative.

Preferably, the preservative is at least one of methyl hydroxybenzoate, ethyl hydroxybenzoate, propyl hydroxybenzoate, phenoxyethanol and tocopherol.

Preferably, the dosage of the preservative is 0.01-0.02% of the total mass of the lipstick containing the pitaya pigment.
