Problems solved by technology

n-Butyl cyanoacrylate has attracted much attention due to its low toxicity and biodegradable polymers. It has been reported as a drug carrier to prepare nano-drug capsules with good targeting, but it is used as a wall material. Applied to the fragrance industry, especially the research on the fragrance of Jasmine grandiflora has not been reported

Abstract

The invention discloses a preparation method of polybutylcyanoacrylate-encapsulated jasminum grandiflorum essence capsule, wherein the nano jasminum grandiflorum essence capsule is prepared by the following raw materials in parts by weight: 0.2-0.5 parts of jasminum grandiflorum essence, 1.0-2.3 parts of polyoxyethylene (20) sorbitan monolaurate, 0.4-1.0 part of butylcyanoacrylate monomer and 96-100 parts of deionized water. As tested by a dynamic laser particle sizer, the nano jasminum grandiflorum essence capsule prepared according to the method of the invention has the average particle diameter of 112nm, the particle size distribution coefficient of 0.104 and stable existence of system, and has the advantages of slow release of fragrance and long fragrance lasting time, etc.

Description

technical field [0001] The present invention relates to a preparation method of Dahuajasmine essence capsule, more specifically relates to a preparation method of Dahuajasmine essence capsule using nano-scale polybutylcyanoacrylate as wall material. Background technique [0002] As an important part of fine chemicals, flavors and flavors have been widely used in daily cosmetics, food, tobacco, medicine and other industries. The main function of fragrance is to give flavored products a unique aroma to meet the needs of consumers. Jasmine grandiflora essence is widely used in high-end cosmetics and aromatherapy because of its pleasant fragrance. It has a large demand in the market and is deeply favored by consumers. However, aromatic substances are volatile and have poor thermal sensitivity, which cannot meet the requirements of consumers. Therefore, improving the thermal stability of flavors and the persistence of fragrance is an urgent problem to be solved in the current f...
