Description

Handmade soap containing grape seed polyphenol and wood ginger seed essential oil and preparation method thereof Technical Field The invention belongs to the technical field of daily chemical industry, relates to a handmade soap processing technology, and in particular relates to a handmade soap containing grape seed polyphenol and wood ginger seed essential oil and a preparation method thereof. Background The handmade soap is one of the main cleaning products because of the natural grease used as the raw material, which is not easy to cause skin dryness after cleaning. However, the existing handmade soap is mainly focused on cleaning function and lacks additional skin care effect, and partial products are prepared by adding chemical synthesis components for pursuing efficacy, so that sensitive muscle discomfort is easily caused. Grape seed polyphenol is a natural antioxidant, can remove free radicals and reduce skin oxidative damage, and the wood ginger seed essential oil contains active ingredients such as natural citral and the like, and has the effects of relieving and inhibiting bacteria. The two are combined with natural grease to prepare handmade soap, so that the maintenance effect can be improved on the basis of cleaning, the requirements of consumers on natural and multifunctional daily chemical products are met, and related technical schemes are not disclosed at present. Disclosure of Invention The invention aims to overcome the defects of the prior art and provide the handmade soap which is not added with chemical synthesis preservative and essence, is mild and non-irritating and contains grape seed polyphenol and wood ginger seed essential oil. The invention solves the technical problems by adopting the following technical scheme: The handmade soap comprises, by weight, 15-25 parts of animal fat, 20-30 parts of palm oil, 10-20 parts of coconut oil, 5-8 parts of sodium hydroxide, 0.5-2 parts of grape seed polyphenol, 0.3-1 part of wood ginger seed essential oil and 12-18 parts of deionized water. And the animal fat is one or more than two of beef tallow, mutton tallow or lard, and the acid value of the animal fat is less than or equal to 2mg KOH/g. Moreover, the purity of the grape seed polyphenol is more than or equal to 95%, the essential oil of the wood ginger seeds is natural essential oil extracted by a steam distillation method, and the citral content is more than or equal to 60%. The preparation method of the handmade soap comprises the following steps: The method comprises the steps of S1, weighing sodium hydroxide according to parts by weight, adding the sodium hydroxide into deionized water, stirring until the sodium hydroxide is completely dissolved, cooling the mixture to 40-45 ℃ to obtain alkali liquor, S2, mixing animal fat, palm oil and coconut oil, heating the mixture to 50-55 ℃ to completely melt the mixture, stirring the mixture uniformly to obtain mixed fat, S3, slowly pouring the alkali liquor obtained in the step S1 into the mixed fat of the step S2, stirring the mixture while reversing the alkali liquor until the system is in a Trace state, sequentially adding grape seed polyphenol and wood ginger seed essential oil, continuously stirring the mixture for 5-8 minutes, S4, pouring the mixture into a mold, standing the mixture for 24-36 hours at 25-30 ℃ to perform preliminary saponification, S5, demoulding, and placing the soap blocks in a ventilated, dried and light-resistant environment, and curing the soap blocks for 30-45 days to obtain the finished product. The invention has the advantages and positive effects that: 1. The raw materials are natural, the grease base material is prepared by compounding animal grease and vegetable grease, and is matched with natural grape seed polyphenol and wood ginger seed essential oil, so that the grease base material is free of chemical synthesis preservative and essence, mild and free of irritation. 2.
