technical field

The invention relates to the technical field of daily necessities, and relates to a preparation method of gardenia whitening and acne-removing handmade cold-process soap.

Background technique

Gardenia (Gardenia jasminoides), also known as yellow gardenia, mountain gardenia, red branch, etc., is an evergreen shrub of Rubiaceae, mainly produced in Jiangxi, Zhejiang, Hunan and other places. Gardenia fruit is a traditional Chinese medicine, and it is also one of the first batch of medicinal and edible resources promulgated by the Ministry of Health. Modern pharmacological studies have shown that gardenia has antioxidant, anti-inflammatory, analgesic, anti-microbial, liver-protecting and choleretic, and blood-sugar-lowering effects. Studies have shown that gardenia ethyl acetate extract and 90% ethanol extract can inhibit the ear shell swelling caused by xylene and the toe swelling caused by formaldehyde, and the anti-inflammatory effect of ethyl acetate extract is not as good as that of ethanol extract; at the same time , Both have therapeutic effects on soft tissue injuries in mice and rabbits, and the therapeutic effect of ethyl acetate extract is better than that of ethanol extract. Gardenia has a moderate antibacterial effect on Staphylococcus aureus, hemolytic streptococcus, catarrhal coccus, diphtheria bacillus, and Conjugate bacillus hominis. Gardenia fruit water decoction can kill Leptospira and Schistosoma in vitro, and has anti-echo virus effect; water extract can inhibit various skin fungi in vitro. The water extract of gardenia fruit has inhibitory effect on a variety of fungi, so it has a certain cleaning and healthy effect on the skin, but has no such effect on bacteria. Gardenia yellow pigment is yellow to yellowish brown, with a special smell but does not affect the fragrance of cosmetics. It dissolves quickly in water and can form a clear, bright yellow that is bright and pleasing to the eye. It also has pharmacological effects. It is used in cosmetics Feasibility is mainly determined by its physicochemical properties. Gardenia contains gardenia essential oil, which is the main raw material for extracting gardenia essence. The chemical components of gardenia essential oil are mainly linalool (21.09%), camphene (7.25%), α-caryophyllene (6.49%), geraniol (5.72%), α-farnesene (5.35%) Wait. Among them, linalool has a typical rose fragrance, geraniol has a sweet fruit fragrance, and α-farnesene has a floral fragrance and has stronger antioxidant capacity.

Cold-process soap refers to handmade soap in a narrow sense, which refers to handmade soap obtained by saponification of oil and lye at 45°C. The formula is: oil + alkali (sodium hydroxide or potassium hydroxide dissolved in water) = soap + natural glycerin. Because high temperature is avoided in the soap making process, the natural vitamins and nutrients contained in vegetable oil and other additives are retained to the maximum extent, so it is the best skin care product. The skin also needs to absorb nutrients through contact, and maintenance in the bath is the fastest and most effective method. When the pores of the whole body are relaxed, use plant soap to make the skin easy to absorb, relax, and not tight. All cold soaps will naturally produce about 20% natural glycerin during the saponification process, which is the best natural moisturizer for the skin and forms a natural protective film on the skin. Vegetable oil contains a large number of nutrients that do not participate in saponification.
