Abstract

The invention discloses colorless, odorless and nontoxic tea-seed oil for cosmetics and a preparation method of the tea-seed oil. The preparation method comprises the following steps: (1) degumming, acidification and alcohol-water extraction: adding water into crude oil of the tea-seed oil for degumming, and conducting acidification, alcohol-water extraction and filtration to obtain tea-seed oil subjected to alcohol-water extraction; (2) absolute ethyl alcohol extraction: extracting the tea seed oil subjected to alcohol-water extraction with absolute ethyl alcohol and conducting filtering to obtain the tea seed oil subjected to absolute ethyl alcohol extraction; (3) heterogeneous dewaxing: adding activated carbon into the tea seed oil extracted by the absolute ethyl alcohol, and conducting stirring, cooling and filtering to obtain dewaxed tea seed oil; and (4) solvent residue removal and activated carbon adsorption: subjecting the dewaxed tea seed oil to solvent residue removal, activated carbon adsorption and filtration, so as to obtain colorless and odorless tea seed oil for cosmetics. The method is low in cost, uses water and a safe organic solvent, does not use a high-temperature deodorization method, and has the advantages of high decoloration, deodorization and detoxification rates, low loss rate of the tea seed oil, high purity of the tea seed oil and mechanization.

Description

technical field [0001] The invention belongs to the technical field of refining oil for cosmetics, and in particular relates to a colorless, odorless and non-toxic tea seed oil for cosmetics and a preparation method thereof. Background technique [0002] Camellia oil, also known as camellia oil, is the oil contained in the camellia seed, the fruit of the camellia tree. Tea seed oil is characterized by small output, high price, and prominent nutritional and health effects. According to research, the content of unsaturated fatty acids in tea seed oil is as high as 90%, of which monounsaturated oleic acid accounts for 74-87%. It also contains various health ingredients such as tea saponin, squalene and vitamin E. Camellia oleifera trees are suitable for growing in mountainous areas, and are distributed in hills and mountainous areas in southern my country. Among them, Hunan, Hubei, Henan, Jiangxi, Guangxi, Guangdong and Yunnan provinces are the main producing areas of tea seed...
