The invention discloses a composition with an anti-aging effect and a preparation method and application thereof, and belongs to the technical field of cosmetics. The composition is prepared by compounding a traditional Chinese medicine active component, a moisturizing and permeation promoting component and a repairing and anti-aging auxiliary component, and the traditional Chinese medicine active component is composed of three zymolytes and three fermentation extracts which are respectively prepared from six medicinal and edible traditional Chinese medicine raw materials through differentiated composite enzymolysis and probiotic anaerobic fermentation processes. The problems that traditional Chinese medicine extracts are low in transdermal absorption rate, poor in bioavailability and insufficient in cosmetic system stability are solved, active ingredients are small-molecularized through process optimization, a multi-target synergistic anti-aging system is formed by matching with functional components, the anti-aging and repairing composition has excellent anti-aging and repairing effects, physical and chemical stability and skin safety, and the anti-aging and repairing composition has a good application prospect. The composition is suitable for various skin types and can be widely applied to preparation of anti-aging repair cosmetics.

The application relates to a preparation method and application of a ginsenoside-loaded triple-assembled Pickering emulsion, and belongs to the biomedical technology field. In order to solve the problems that the Pickering emulsion constructed by natural active ingredients in the prior art has insufficient mechanical strength of an interface film, is easy to break and lose stability, has passive release behavior, lacks controllability and environmental responsiveness, and is difficult to realize precise release, a ginsenoside-loaded triple-assembled Pickering emulsion is provided. Through a three-step cascade strategy of "molecule-interface-function", a stable "metal-phenol coordination network" interface layer is constructed on the surface of oil droplets, the physical and chemical stability of the emulsion is fundamentally improved, a Pickering emulsion which is all-natural, highly stable and has a pH response intelligent release function is successfully constructed, and the triple-assembled Pickering emulsion has significant advantages in stability, controllable release and function integration, and provides a feasible technical strategy for a response type delivery system design based on natural products.

The invention relates to the technical field of pigment preparation, discloses an anti-fading plastic pigment which comprises the following components in percentage by weight: 70-90% of tungstate or titanate, 3-10% of rare earth doped ions and 2-8% of transition metal doped ions, and further discloses a preparation method of the anti-fading plastic pigment. Comprising the following steps: S1, preparing a precursor solution: dissolving tungstate or titanate in deionized water, adding a citric acid chelating agent, stirring for 50-60 minutes to form a basic solution, and slowly adding a rare earth doped ion and transition metal doped ion solution; through synergistic doping of rare earth and transition metal ions, doped ions form a stable solid solution structure in barium titanate or tungstate crystal lattices, meanwhile, an optimized high-temperature roasting process and atmosphere control are combined, the thermal stability of the pigment is effectively improved, and ultraviolet absorption and oxidation resistance are enhanced through introduction of the rare earth ions.

The application discloses a composition with anti-aging efficacy and a preparation method and application thereof, and belongs to the technical field of cosmetics. The composition is compounded by a traditional Chinese medicine active component, a moisturizing and penetration promoting component and a repair and anti-aging auxiliary component, wherein the traditional Chinese medicine active component is composed of three kinds of enzymolysis products and three kinds of fermentation extracts prepared respectively by differential complex enzymolysis and probiotic anaerobic fermentation process of six kinds of medicinal and edible traditional Chinese medicine raw materials. The application solves the pain points of low transdermal absorption rate, poor bioavailability and insufficient stability of the traditional Chinese medicine extract in the cosmetic system, realizes the small molecule of the active ingredient through process optimization, forms a multi-target point synergistic anti-aging system by matching the functional components, has excellent anti-aging repair efficacy, physical and chemical stability and skin safety, is suitable for various skin qualities, and can be widely applied to the preparation of anti-aging and repair cosmetics.
