[0003] Patent CN 102399452 A "A Method for Extracting Pigment from Grape Skin" discloses a method of using water to extract the pigment in grape skin and then using ethanol to purify the pigment. This method can extract pigment from natural grape skin, but the method can obtain pigment The purity is not high and the purification with industrial ethanol makes the pigment can not be used in direct cosmetics
Patent CN106009763 A "A Method for Extracting Natural Red Pigment from Dragon Fruit and Its Application" discloses a method for extracting pigment by enzymatic hydrolysis, which is simple and easy to operate, but biological enzymes can easily cause skin allergies. Used in cosmetics

Embodiment 1

[0019] After the dragon fruit is washed and dried naturally, peeled and seeded, the sample is processed into a paste by a paste maker for 10 minutes, and then the sample is ground with a homogenizer for 10 minutes to form a homogenate; weigh 5.0 kg of grinding liquid and After mixing 25L of distilled water, centrifuge at 400W ultrasonic power, 200W microwave power, and 30°C for 25 minutes. Concentrate under pressure to obtain a natural fruit pigment crude extract concentrate with a density of 1.15-1.22g / mL; add 10% tetrahydrofuran-n-octanoic acid-water supramolecular solvent to the crude extract, vortex for 20s, and centrifuge to form two phases and remove After adding the phase, continue to add 45% choline chloride-urea eutectic reagent-0.25g / mL sodium sulfate solution, vortex for 20s, and centrifuge to form two phases. Take out the upper phase and add ethanol to the upper phase to dissolve the eutectic solution. The reagent is precipitated to recover the eutectic reagent, an...

Embodiment 2

[0021] After the cherry fruit was washed and dried naturally, peeled and deseed, the sample was processed by a paste machine for 10 minutes, and the sample was ground into a paste, and then the sample was ground with a homogenizer for 12 minutes to form a homogenate; weigh 5.0 kg of grinding liquid and After mixing 25L of distilled water, centrifuge at 400W ultrasonic power, 150W microwave power and 40°C for 30 minutes, and then microwave-ultrasonic extract the residue with deionized water for 3 times. Concentrate under pressure to obtain a natural fruit pigment crude extract concentrate with a density of 1.15-1.22g / mL; add 15% tetrahydrofuran-n-octanol-water supramolecular solvent to the crude extract, vortex for 20s, and centrifuge to form two phases After removing the upper phase, continue to add 50% choline chloride-glycerol deep eutectic reagent-0.35g / mL sodium citrate solution, vortex for 20s, and centrifuge to form two phases. Take out the upper phase and add ethanol to ...

Embodiment 3

[0023] After the mulberries were washed and dried naturally, the samples were processed by a paste machine for 10 minutes, and then the samples were ground into a paste, and then the samples were ground with a homogenizer for 10 minutes to form a homogenate; Ultrasonic power, microwave power of 200W and microwave-ultrasound for 30 minutes at 40°C, then centrifuged, the residue was extracted with deionized water microwave-ultrasonic for 3 times, the supernatant was combined, and the supernatant was concentrated under reduced pressure to obtain a density of 1.15- 1.22g / mL natural fruit pigment crude extract concentrate; add 14% tetrahydrofuran-n-hexanol-supramolecular solvent to the crude extract, vortex for 20s, and centrifuge to form two phases, remove the upper phase and continue to add 50% tetrahydrofuran Betaine-glycerol deep eutectic reagent-0.35g / mL sodium citrate solution was vortexed for 20s and then centrifuged to form two phases, take out the upper phase and then add e...

Abstract

The invention discloses a preparing method of natural fruit pigment for cosmetics, which relates to the technical field of beauty and cosmetics and is characterized in that: firstly, efficiency of extracting the natural pigment from fruits is greatly improved by utilizing the microwave-ultrasonic-assisted extraction technology; then protein and macromolecular substance of the fruit pigment extracts are precipitated and purified by using confinement characteristics of supramolecular solvent; and finally by utilizing eutectic reagent-aqueous two-phase, strongly polar materials except fruit pigment extraction species are extracted to further purify the pigment and the natural and high-purity fruit pigment is obtained. The natural pigment obtained by using the method can be directly added to cosmetics including lipsticks, lip-moistening liquids, lip glosses, lip care balms, enamels and the like.

Description

technical field [0001] The invention relates to the technical field of beauty and makeup, in particular to a method for preparing natural fruit pigments for cosmetics. Background technique [0002] The use of cosmetics is very common in today's society. As one of the most popular types of cosmetics for women, make-up products often add a certain amount of pigment in order to achieve effects such as increasing natural color and highlighting facial features. At present, a variety of pigments for cosmetics are made by converting water-soluble fuels into insoluble pigments through "lake" colorants. This pigment contains heavy metal substances, and long-term use will cause skin damage and affect health. Therefore, it is of great significance to develop green and healthy natural pigment pigments. [0003] Patent CN 102399452 A "A Method for Extracting Pigment from Grape Skin" discloses a method of using water to extract the pigment in grape skin and then using ethanol to purify t...
