Problems solved by technology

However, its disadvantage is that the high temperature process can easily lead to the destruction of important active ingredients such as unsaturated fatty acids in oils, thereby changing or weakening some physical and chemical properties and protective capabilities of the extract.

Embodiment 1

[0013] Embodiment 1——conventional organic solvent method extracts ostrich oil

[0014] Weigh 200g of ostrich fat, place it in a 2000mL round bottom flask, add petroleum ether (30-60g) equivalent to 5 times the weight of ostrich fat, and reflux extraction twice, each time for 2h. The extracts were combined, filtered with suction, and the filtrate was rotary evaporated at 40°C until there was no distilled liquid, so as to remove the petroleum ether solvent. The obtained extract was a yellow oil, which gradually appeared as a flocculent solid when placed at room temperature, and gradually became lighter in color, and finally formed a light yellow semi-solid, and cooled to a white solid. The extraction rate is as high as 78%.

Embodiment 2

[0015] Embodiment 2——supercritical extraction method extracts ostrich oil

[0016] Take by weighing 200g ostrich fat, place in the 1L extraction kettle of HA-220-50-06 supercritical extraction equipment (Huaan Supercritical Extraction Co., Ltd.), adjust the supercritical equipment to reach the following conditions: extraction pressure: 20MPa, extraction temperature: 45 °C, CO 2 Flow rate: 15L / h, Separation I pressure: 8MPa, Separation I temperature: 35°C, Separation II pressure: 4-6MPa (according to gas tank pressure), Separation II temperature: 35°C, Extraction time: 5h. After the extraction, the extract collected from Separation I was a white solid paste, which was white semi-solid at room temperature and white solid when cooled. The extract can be directly used as the protective cosmetic base of the present invention without any treatment. The extraction rate reaches 71.6%.

Embodiment 3

[0017] Embodiment 3——Supercritical extraction method extracts emu oil

[0018] Weigh 250g of emu fat, place it in a 1L extraction kettle, and adjust the supercritical equipment to achieve the following conditions: extraction pressure: 25MPa, extraction temperature: 50°C, CO 2 Flow rate: 35L / h, Separation I pressure: 8MPa, Separation I temperature: 40°C, Separation II pressure: 4-6MPa (depending on the tank pressure), Separation II temperature: 40°C, Extraction time: 5h. After the extraction, the extract collected from Separation I was a white solid paste, which was white semi-solid at room temperature and white solid when cooled. The extract can be directly used as the protective cosmetic base of the present invention without any treatment. The extraction rate was 20.6%.

Abstract

The invention provides a skin-protecting cosmetic host material. An oil and fat product is extracted from ratite birds such as ostriches, emus and the like by an organic solvent extraction method or a supercritical extraction method. The skin-protecting cosmetic host material is rich in important active ingredients such as unsaturated fatty acid and the like and the active ingredients comprise oleic acid, linoleic acid, linolenic acid and the like, wherein the oleic acid content is highest and accounts for 32 to 45 percent of the weight of the total fatty acid ingredients. The skin-protecting cosmetic host material has good effect of promoting percutaneous absorption, capacity of reducing the resistance of other functional components penetrating the skin, no toxicity and nonirritant to human skin, effects of repairing skin injury, diminishing inflammation and stopping pain, contributing to regeneration and moistening the skin and obvious skin-protecting effect, so the host material is a safe and ideal skin-protecting cosmetic host material.

Description

technical field [0001] The invention relates to a cosmetic base material and a preparation method thereof, in particular to a protective cosmetic base material for skin protection and a preparation method thereof, belonging to the technical field of cosmetic materials. Background technique [0002] Bases used in cosmetics can be classified into aqueous bases and oily bases. Water-based bases are represented by glycerin, propylene glycol, and polyethylene glycol, and the main purpose is to impart a moist feeling; oily bases are represented by triglycerides and silicone oil, and the main purpose is to give the skin a smooth feeling without stickiness. However, due to the relatively low mutual solubility of these two matrices, the beauty cosmetics currently on the market will add a large number of surfactants, thickeners, emulsifiers and other additives to the matrices to adjust the physical and chemical properties of the cosmetics. The characteristics of two aspects of moist ...
