Sustained release micro-capsule and application thereof to anti-allergy face cream

Abstract

The invention discloses a sustained release micro-capsule and application thereof to anti-allergy face cream. The sustained release micro-capsule is a spherical micro-capsule which is of a core-shell structure, a capsule wall contains polyethylene glycol, a capsule core contains porous starch, and anti-allergy active ingredients are adsorbed by the porous starch. The sustained release micro-capsule and the application have the advantages that the embedding rate of the sustained release micro-capsule can reach 94%, and a sustained release effect can be realized within 4h; the sustained release micro-capsule is added into the anti-allergy face cream, so that sustained release anti-allergy effects can be realized by the anti-allergy face cream, and allergic skin soothing effects can be effectively prolonged.

Description

technical field [0001] The invention belongs to the field of microcapsules, in particular to a slow-release microcapsule and its application in anti-allergic face cream.

[0004] However, the current anti-allergic products are all anti-allergic active ingredients are directly added to the product without certain protection, resulting in active ingredients being easily affected by adverse factors in the external environment during storage and losing their activity.

And more importantly, when the existing anti-allergic products are used, the anti-allergic active ingredients are released at one time to achieve a short-term anti-allergic effect, and do not have the function of lasting anti-allergic curative effect; and one-time release of large doses of Anti-allergic active ingredients, which may be too much for the skin and cause allergies instead
