Description
Technical Field
The invention relates to the field of handmade soaps, in particular to a handmade soap with shortened saponification time and a preparation method thereof.
Background
Handmade soaps are popular special washing products with health care function in recent years. The raw materials are natural animal and vegetable oil, so that the skin care cream is mild in components, rich and fine in foam, thorough and transparent in skin cleaning, and free of burden, damage and allergy to the skin after long-term use. The production of handmade soap is mainly finished by small and medium enterprises or household workshops, and a cold soap making process is mostly adopted. The cold method for preparing soap comprises slightly heating oil to melt, mixing with alkali, slowly reacting, adding additives such as essential oil and pigment to adjust soap quality, air drying soap at room temperature, cutting into blocks, and air drying for 4-6 weeks. In the cold soap making process, the glycerin is completely stored in the soap body, the content of the glycerin accounts for almost one fourth of the whole soap, and the glycerin is a natural moisturizing humectant, so that the handmade soap is much more moisturizing and moisture-retaining than the commercially available soap when in use.
With the deep mind of the natural health and environmental protection concept, the pure natural handmade soap is increasingly popular with middle-aged and young white-collar women, and more consumers can abandon the artificial chemical synthetic cosmetics and select pure natural nursing articles in the future. As a new bath skin care consumption trend, the huge market potential of the pure natural handmade soap makes the soap become one of golden industries in China. There are many brands of skin cleansing and care products on the market, which contain a large amount of chemical components, are not only harmful to the skin of the user, but are also not environmentally friendly. Consumers who advocate natural and healthy ideas begin to select products with pure natural components, and the pure natural handmade soap is made of 100% of natural materials, contains rich moisturizing components, namely natural glycerin and rich natural antioxidants, and becomes an increasingly popular bath skin care product for replacing chemical finished products all over the world.
The addition of alkali in the process of preparing soap by a cold method is the guarantee of saponification reaction, and is a key technology in the field of soap production. In the traditional cold method soap making process, strong alkali sodium hydroxide (NaOH) is required to be added to realize the saponification reaction of grease to prepare soap base.
Under the condition of low temperature, the saponification reaction rate is slow, so that the consumption of sodium hydroxide is slow, the residual quantity in a soap base is large, and a large amount of subsequent time is required to be occupied for air drying and saponification to reduce the content of sodium hydroxide, so that the time cost of cold soap making is increased, and the product yield is reduced. In order to reduce the residue of sodium hydroxide and shorten the time of the late saponification reaction, the search for a novel alkali compound to replace strong alkali such as sodium hydroxide is an inevitable choice.
