Description

Technical Field

[0001] The invention relates to the field of hand creams, and in particular to a method for preparing a Pu'er raw tea hand cream. Background Art

[0002] As people pay more and more attention to natural skin care and health and beauty, the multiple functions of tea have gradually been recognized and accepted by more and more people, and tea cosmetics have also risen rapidly around the world. Pu'er raw tea belongs to the large-leaf sun-dried green tea, and its ingredients are 3-4 times that of small-leaf varieties. Studies have found that raw tea has strong in vitro antioxidant, hypoglycemic and hypolipidemic effects, and it is rich in tea polyphenols, amino acids, caffeine, vitamins, minerals and other substances. Tea polyphenols have multiple functions such as antioxidant, whitening, anti-apoptosis, anti-radiation, antibacterial, and whitening; theanine has the effects of moisturizing, anti-wrinkle, and moisturizing the skin; caffeine has the effects of antioxidant, anti-aging, improving dark circles around the eyes, and reducing eye swelling. At present, most tea skin care products use tea extracts as additives, but the aroma substances are seriously lost during the tea extraction process, while tea pure dew retains more tea aroma. Therefore, adding raw tea pure water and raw tea extract in a certain proportion can retain the aroma of Pu'er raw tea and the effective ingredients of the substances contained in Pu'er raw tea. The hand cream made can have tea fragrance without the need for fragrance.

[0003] Jojoba oil is rich in vitamin D and protein, and is a very good moisturizing oil that can maintain skin moisture, prevent wrinkles and soften the skin; sweet almond oil is a relatively stable unsaturated fatty acid oil with a very good moisturizing effect; it has great development prospects in the cosmetics field.

[0004] At present, some cold-processed hand creams on the market have poor stability, while hot-processed hand creams lack delicate skin feel, and both have problems such as thick application and rubbing mud. Therefore, it is very necessary to use hot-processing and cold-processing combined with emulsification technology with better skin feel and more stable quality, combined with the rich contents and skin care effects of Pu'er raw tea to prepare hand creams that prevent skin wrinkles and roughness, resist radiation damage, sterilize, and resist allergies. Summary of the invention
