Problems solved by technology

There are certain defects in the application of the existing carrier system to the packaging of essences for cosmetics. The combination of gelatin and gum arabic is commonly used as an auxiliary material, and the coagulation method is used to wrap the essences. This method requires the addition of formaldehyde, and the residue of formaldehyde is harmful to the skin. Stimulation is greater; for example, the commonly used coagulation method, polymerization method, interface polymerization method, and in-situ polymerization method need to use cross-linking agents, catalysts, strong electrolytes and other substances, which have certain irritation and damage to the skin, so they are not suitable for Cosmetics

Abstract

The invention discloses osmanthus essence microcapsule powder as well as a preparation method and application thereof. A heat-resistant slow-release type osmanthus essence microcapsule comprises the following components in percentage by weight: 5-25 percent of oil-soluble osmanthus essence, 30-47 percent of modified Arabic gum A-2010 and 43-51 percent of maltodextrin. The microcapsule powder is high in stability and water solubility; formaldehyde, cross-linking agents, catalysts or strong electrolytes do not need to be added in a preparation process; the method is simple, controllable and high in repeatability; the retention rate of fragrance at high temperature reaches 85 percent, and the retention rate of the fragrance reaches 90 percent after three months; the osmanthus essence microcapsule powder is high in heat resistance and good in slow release property, and can be applied to preparation of cosmetics containing the oil-soluble osmanthus essence.

Description

technical field [0001] The invention belongs to the technical field of carrier systems in cosmetic preparation technology, and in particular relates to a microcapsule powder loaded with sweet-scented osmanthus essence, a preparation method and application thereof. Background technique [0002] Osmanthus fragrans essence is mainly a fat-soluble substance, insoluble in water, volatile, very unstable in nature, difficult to store, store and add. At present, encapsulation technology (carrier technology) is generally used to improve the compatibility, stability and sustained release of flavors. Carrier technology can improve the compatibility, stability and sustained release of flavors. Researchers at home and abroad have turned their attention to carrier technology and developed carrier transport systems such as microcapsules, liposomes, and gels. Microcapsule technology is a technology that coats solid or liquid with film-forming materials to form tiny particles. Microcapsules...
