Abstract

The invention provides a preparation method of a natural menthol or peppermint oil hydrogel. The method comprises steps as follows: (1) a water-soluble natural pigment is dissolved in essential oil hydrolat for use; (2) water-soluble natural menthol or peppermint oil is added to the essential oil hydrolat, and the mixture is evenly stirred for use; (3) carbomer is added to the essential oil hydrolat, and the mixture is left to stand for swelling; (4) under the vacuum condition, triethanolamine is added, the mixture is evenly stirred, then a preservative and a wetting agent, namely, glycerin, are added, the mixture is evenly stirred, and the hydrogel product is obtained. Plant hydrolat is adopted as an aqueous phase, has aromatic fragrance, is free of synthetic essence components and conforms to the environmental protection requirement, besides, the water-soluble plant pigment instead of a synthetic pigment is adopted, can beautify the product and conforms to the health requirement, the product is bright in appearance, is prepared under the vacuum condition and is free of bubbles, and conditions that air bubbles are introduced in the product under the non-vacuum condition and bacteria and microorganisms in the air affect the quality of the product are completely eradicated.

Description

technical field [0001] The invention relates to the technical field of hydrogel preparation methods, in particular to a preparation method of natural menthol or mint oil hydrogel. Background technique [0002] Hydrogel is a gel in which water is the dispersion medium. A part of hydrophobic groups and hydrophilic residues are introduced into the water-soluble polymer with a network cross-linked structure. joint polymer. It is a polymer network system, which is soft in nature, can maintain a certain shape, and can absorb a large amount of water. [0003] As a superabsorbent material, hydrogel is widely used in women's sanitary napkins, diapers, sanitary products, fragrance carriers, and paper towels. The amount of hydrogel is not large, and the price is acceptable to consumers. Mainly cross-linked polyacrylates and starch-2 acrylic acid grafted polymers. [0004] The product of essential oil hydrogel is a kind of product that develops extensively at present. The patent "C...
