Abstract

The invention discloses a method for preparing a herbal essence microcapsule. The method comprises the following steps: firstly preparing gelatin liquid and chitosan liquid; weighing a herbal essence, dropwise adding to the gelatin liquid, adding monoglyceride, mixing evenly at a high speed, and then homogenizing, so as to prepare a homogenized liquid; adjusting the pH of the homogenized liquid to 7.2-7.6; pouring the chitosan liquid into the homogenized liquid, carrying out complex coacervation reaction for 20-25 minutes; adding 50-60mL of formaldehyde to the liquid which is subjected to complex coacervation reaction, and carrying out curing reaction for 1-2 hours; and finally standing, centrifuging and washing the reaction liquid, and drying in a freeze-drying machine, so as to prepare the herbal essence microcapsule. The herbal essence microcapsule prepared by the method disclosed by the invention is good in embedding effect, has a good emulsification effect, and is capable of effectively preventing fragrance from releasing; the prepared microcapsule product is relatively uniform in quality; and the activity of natural pigments is not destroyed.

Description

technical field [0001] The invention belongs to the field of microcapsules, and in particular relates to a preparation method of herbal essence microcapsules. Background technique [0002] The human body is undergoing metabolism every day. The metabolites secreted by sweat glands and sebaceous glands adhere to the skin, which will bring discomfort to people. This requires people to clean their skin frequently. Shower gel is a liquid cleaning agent to help people clean their skin. . However, with the improvement of living standards, traditional shower gels with cleaning functions can no longer meet the needs of consumers. More consumer needs, such as fragrances, have emerged at the historic moment, and the development of shower gels with lasting fragrances and fragrance effects Shower gel has an important meaning. [0003] Most of the fragrances are sensitive ingredients, which are greatly affected by the external environment such as temperature, light, and especially the...
