[0035] 1. Preparation of Hemp Leaf Extract

[0036] After drying, 100 g of mature hemp leaves were pulverized by a pulverizer, passed through a 40-mesh sieve, added 2 L of 95% ethanol aqueous solution, extracted under reflux at a temperature of 75° C. for 2 h, and filtered to obtain a filtrate. Add activated carbon to the filtrate, the amount of activated carbon accounts for 0.4% of the mass of the filtrate, stir and decolorize at a temperature of 50° C. for 30 minutes, and centrifuge at 3000 rpm for 20 minutes to obtain a supernatant. Add 300g of freshly calcined quicklime to the supernatant, let it stand overnight, then reflux in a water bath for 5-6h, centrifuge at 1500rpm for 5min to obtain a supernatant, then concentrate it with a rotary evaporator (equipped with a circulating water vacuum pump), water bath temperature: 40 -45°C, rotating speed: 80 rpm, evaporated for 12 hours to obtain hemp leaf extract.

[0037] 2. Preparation of Hemp Seed Oil

[0038] Grind 100g of "...

Embodiment 1

[0040] The hemp leaf extract prepared by the above method and the hemp seed oil are mixed according to the mass ratio of 1:2 to obtain the hemp extract.

[0041] 1. The absorption ability of hemp extract to ultraviolet rays

[0042]Dilute the hemp extract with isopropanol to 0.5 mg per milliliter of crude drug, use the corresponding solvent as a blank control, scan in the wavelength range of 200-400nm, and determine the light transmittance of the hemp extract at each wavelength. Calculation method: first calculate the average light transmittance of each extract at 280, 290, 300, 310, 320nm in the UV-B region and 320, 330, 340, 350, 360, 370, 380, 390, 400nm in the UV-A region rate, and then converted into the average UV absorption rate. The result is as figure 1 , figure 1 The results show that the hemp extract has obvious ultraviolet absorption ability in the UV-A region and UV-B region.

Embodiment 2

[0050] Embodiment 2 Cosmetics containing hemp extract

[0051] According to the following formula: (the following are weight percentages) prepare the cosmetics containing the hemp extract of the present invention.

[0052]

[0053] Preparation method: Add phase A into the oil phase reactor, turn on steam heating, stir at 50rpm, heat up to about 85°C, keep warm until the raw materials melt and mix evenly; add phase B into the emulsification reactor, stir at 50rpm, turn on Heat, slowly raise the temperature to 85°C to make the materials fully mixed evenly; pump the materials in the oil phase kettle into the emulsification reaction kettle, and after the two phases are mixed, turn on the homogenization, 5000rpm homogenization for 30min; keep stirring, and the temperature drops to 40°C When phase C is added, the cosmetic product is obtained. The adding amount of essence and antiseptic can add appropriate amount according to the routine technology of the present invention.

Abstract

The invention discloses a cannabis extract with anti-sensitive and moisture retention functions and new application thereof to anti-sensitive and moisture retention cosmetics. The cannabis extract contains cannabis leaf extracts and cannabis seed oil, wherein the mass ratio of the cannabis leaf extracts to the cannabis seed oil is 1:(0.2-5). The cannabis extract is added to cosmetics, cannot cause irritation to human skin, can achieve effective and lasting moisture retention, makes skin elastic and glossy, can effectively achieve relieving, relaxing, repairing, anti-sensitive and anti-inflammation functions on sensitive skin, can absorb ultraviolet rays and has a good sun-shade function, and accordingly the cannabis extract has the advantages of being efficient, environmentally friendly and safe and is a brand new natural anti-sensitive and moisture retention component. The cannabis extract can be compatible with various acceptable matrixes in the cosmetic field and be prepared into various forms such as skin cream, skin emulsion, lotion, jelly, essence, masks, eye cream, facial cleanser, mist or spray.

Description

technical field [0001] The invention belongs to the fields of natural medicinal chemistry and cosmetics technology, and in particular relates to an anti-sensitive and moisturizing hemp extract and its application in cosmetics. Background technique [0002] Modern people have a fast-paced life, high pressure, poor sleep, coupled with increasingly serious environmental pollution, ultraviolet rays, computer electrical radiation, smoking and drinking, lack of exercise, eating too much processed food and excessive intake of oil, etc. These factors have caused many Skin problems, such as dry skin, peeling skin, dark yellow skin color or even chloasma, sun spots, sensitive skin, etc. [0003] It's no secret that nearly every skin concern has to do with moisture retention and replenishment. Moisture is the first element of beautiful skin. Whitening, sun protection, oil control, etc. are completed on the basis of moisturizing and hydrating. Any season, age, skin type, skin problem ...
