AI Technical Summary

Problems solved by technology

The microcapsules have small particle size, hard outer wall and poor air permeability, so they are not suitable for use in cigarette filters
[0009] The research on processing these free radical scavengers into multivesicular liposomes and putting them into cigarette filters to scavenge gaseous free radicals (reduced radicals) has not been reported so far, let alone the research based on the synergistic composition of squalene and astaxanthin. Preparation technology and application report of multivesicular liposome

Abstract

The invention discloses a preparation method of a squalene and astaxanthin composite multivesicular liposome and a radical lowering and harm reducing method thereof. The multivesicular liposome is prepared from 12-18 parts of hydrogenated phospholipid, 10-20 parts of stabilizer, 10-15 parts of surfactant and the balance of squalene and astaxanthin composite. Through microencapsulating the squalene and astaxanthin composite, the defect that the squalene and astaxanthin composite is easily oxidized in the air and loses effectiveness is overcome, and the effect of increasing the stability of a squalene and astaxanthin blending synergy composite is achieved. The multivesicular liposome is built in a cigarette filter tip made of cellulose acetate fiber in the forming process of a cigarette filter tip bar, and 0.5-1.5g of multivesicular liposomes is arranged in each cigarette filter tip, so that a cigarette filter tip capable of lowering the harm of cigarettes is obtained; the surface area of the multivesicular liposome is large, so that anti-oxidant makes full contact with main stream smoke, gas-phase free radical in the main stream smoke can be effectively removed, and powerful technical support is provided for solving the smoking and health problem.

Description

technical field [0001] The present invention relates to the technical field of chemistry, and more particularly, to a multivesicular liposome containing a squalene and astaxanthin composition, a preparation method thereof, and an application in reducing the harm of cigarette bases. Background technique [0002] Thousands of compounds produced by smoking and the harm caused by high concentrations of free radicals to the human body have attracted widespread attention. And free radicals are the most harmful to the body, which can cause lung disease, heart disease and cancer. These free radicals can cause serious harm to smokers. Smoking produces high concentrations of free radicals, including relatively long-lived solid-phase free radicals, quinones and semiquinones, polycyclic aromatic hydrocarbon free radicals, and reactive oxygen radicals such as superoxide anion (O 2 - ), hydrogen peroxide (H 2 O 2 ), hydroxyl radicals ( OH), singlet oxygen ( 1 O 2 ) and lipid peroxid...
