Method for processing base oil of tea oil cosmetic

Abstract

The invention discloses a method for processing base oil of a tea oil cosmetic. The method comprises the steps that 1, tea oil squeezed crude oil meeting the national standard is finely filtered, and a citric acid solution accounting for 0.02% of oil weight is added; 2, after an acid reaction, caustic soda liquid is added at normal temperature for an alkali reaction, and after the tea oil is heated, soap removing is carried out; 3, acid is added to the tea oil obtained after soap removal, washing is carried out, and after the washed oil is subjected to vacuum drying, polishing filter is carried out; 4, the tea oil obtained after polishing filter is heated, and meanwhile a mixed decolorising agent is added for decoloration in a bleaching tower; 5, the decolored oil is deodorized at low temperature; 6, the deodorized oil is winterized and filtered, and then the base oil of the tea oil cosmetic is obtained if the oil passes inspection. After the method is adopted, the color reversion problem of the base oil is solved, the micronutrient content of the product is effectively increased, production cost is obviously reduced, the processing rate is greatly increased, the product can be directly smeared as suntan oil and can also be used for daily skin care, and the life quality of people is improved.

Description

technical field [0001] The invention relates to the field of camellia oil cosmetic base oil, in particular to a processing method of camellia oil cosmetic base oil. Background technique [0002] The processing method of the existing camellia oil cosmetics base oil, the processing technology adopted is basically similar to the soybean oil refining process, is to hydrate the camellia seed crude oil with alkali refining, wash, dry, decolorize, deodorize, and then winterize (similar to corn oil) . Specifically: After filtering the crude oil of the pressed oil, heat it to 70-80°C, add 15 degrees of Baume liquid caustic soda for alkali refining, the reaction time is about 20 minutes, after the oil and soap are separated, heat it to 85-95°C and add oil Wash with 10% hot water at 90°C, then vacuum dry; add activated clay and activated carbon to the dried oil and mix evenly (activated clay: activated carbon = 20:1), heat to 105-115°C for 30 minutes, filter and enter deodorization T...

AI Technical Summary

Problems solved by technology

[0003] Adopt existing method, because what adopt is hydration degumming, and do not add acid before washing, can cause the partial emulsification of oil inevitably, because can't solve the difficult problem of emulsification in the tea oil processing; Higher temperature and more excess alkali will inevitably lead to the loss of a large amount of neutral oil, so the yield of finished oil is lower

Since the quality control of degummed oil fails to meet the processing quality requirements of light-colored decolorized oil, and the types and proportions of decolorizers used are unreasonable, it is difficult to meet the requirements for one-time decolorization, and secondary decolorization has to be carried out, which increases production costs and reduces production costs. Productivity

The low temperature not used in the deodorization process, because the process temperature used is the same as that of the camellia oil process, the loss of camellia oil during processing and the loss of non-micronutrients in the oil are much larger than this process, including natural antioxidants, etc. reduced product quality

Due to the lack of proper concentration and dosage of citric acid in the processing process, the long-term low-temperature acid reaction was not carried out, and the acid was not added to further remove metal ions before the alkali refining oil was washed, and the processing temperature was high, which made the color return problem of the product more obvious.
