Abstract: A microcapsule and a preparation method and use thereof are provided. The microcapsule includes a core phase and a shell phase with a volume ratio of (3.4-3.8):(0.8-1.2); wherein the core phase includes 8 wt % to 12 wt % of PVA, 4 wt % to 6 wt % of a density enhancer, 0.1 wt % to 0.3 wt % of an active substance, and a residual amount of water; the shell phase includes an elastomer precursor, a curing agent and silicone oil with a mass ratio of (9-11):(0.8-1.2):(2.5-3). The microcapsules of the present invention release active ingredients completely in milliseconds, and the release process exerts a relatively strong mechanical stimulation intensity on the surrounding environment which can further improve an absorption efficiency to the active ingredients in the fields of pharmaceuticals and cosmetics, and can provide a unique sensual experience in the field of food.

Abstract: Disclosed is a composition having functions of moisturizing, repairing and whitening and use thereof. The composition comprises Dendrobium candidum polysaccharide, a lotus extract and a Glycyrrhiza glabra extract. The lotus extract and the Glycyrrhiza glabra extract can inhibit pigmentation by inhibiting synthesis of melanin, inhibiting transfer of melanin globule, resisting oxidation and improving skin microcirculation, so as to exert the effect of special whitening. Through the synergistic synergy of the three components, and the compounded composition can reduce synthesis of melanin of skin's melanophores, promote expression of keratinocyte cell hydration-related factors, inhibit expression of inflammation-related factors, promote the ability of lipid synthesis and exert multiple effects of whitening, enhancement in moisturizing of the skin, alleviation in inflammation and discomfort of the skin, and improvement in barrier function of epidermis.

Abstract: The present invention provides a solid mask and a preparation method thereof. The solid mask includes a hydrophobic substrate layer and a nanofiber layer, the nanofiber layer has a three-dimensional structure and is electro-spun onto the hydrophobic substrate layer through uniaxial electrostatic spinning technology, and the nanofiber layer is prepared by the following food-grade raw materials in parts by mass: 10 to 30 parts of gelatin, 1 to 30 parts of soya bean lecithin and 0.1 to 10 parts of a functional substance. The present invention provides a solid mask, using gelatin and soya bean lecithin as the framework. The nanofiber layer is a three-dimensional laminate made of fibers having a diameter of a few hundred nanometers. The nanofiber layer has a membrane structure similar to the extracellular matrix. The raw materials of the solid mask are all food-grade raw materials or natural extracts.
