Description

Preparation method and application of supramolecular composition with whitening and moisturizing effects
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a supramolecular composition with whitening and moisturizing effects and an application method thereof.
Background
The term supramolecules was proposed as early as the mid-30 of the 20 th century, and the concept and terminology of supramolecular chemistry was proposed in 1973. The concept of supermolecule chemistry was first proposed by nobel chemical prize-taker in 1987, french scientist j.m.lehn, who pointed out that the supermolecule technology, which is based on covalent bond existing in the field of molecular chemistry and molecular assembly and intermolecular bond existing in the field of molecular chemistry, can be widely applied to raw material extraction, raw material encapsulation, dissolution and synthesis, and formula permeation-promoting technologies of cosmetics, to improve the transdermal absorption rate of active ingredients, the component purity of products, the action time of active ingredients, and to reduce the irritation property, etc.
The supramolecular nano-encapsulation technology is a technology for encapsulating active ingredients into a designed delivery vehicle so that the active ingredients can permeate into cells. The membrane structure of the nano material is very close to that of a cell membrane, and the nano material can wrap effective components and then introduce the effective components into cells to be slowly released in the cells, so that the long-acting and high-efficiency effect is realized. Typically, the skin care sequence is: cleansing-water-essence-emulsion-cream, but the skin care steps of people with neutral, dry, oily and the like are different or different due to different skin types. The four traditional main dosage forms of the skin care product are 'water, milk, cream and essence', which are associated with different dosage forms, and mainly depend on the proportion and the interaction relationship among a water phase component, an oil phase component and an emulsifier in the formula.
People prefer skin lotion because of its fluency and absorbability, and skin cream because of more moisturizing and moisture retention. The difference in the ratio of the parameters between the partial water and the frost is the greatest, i.e. the difficulty factor of the interconversion between them in a short time is the highest. To solve the problem, the invention applies the supermolecule wrapping technology to prepare a composition, the texture of the composition is smooth like water, the color of the composition is milky white like uniform milk, and the composition has a plurality of using methods. The essence water has the effects of moisturizing, efficiently moisturizing, bringing active ingredients contained in the essence water to the deep layer of the skin, bringing deep moisturizing effect to the skin, facilitating skin absorption, activating skin cells, enabling the skin to be glossy and endowing the skin with a moist feeling. Meanwhile, conditions are created for the absorption of other subsequent skin care products, and a channel is opened, so that the subsequent skin care products are more favorably absorbed by the skin. The skin care lotion is used as the lotion for moistening the skin, relieving the dry skin, maintaining the water-oil balance of the skin and the pH value of the skin, giving the most basic care to the skin in the using process, being beneficial to the better effect of the subsequent skin care steps and ensuring the skin to be nursed most properly; the cream has high water content, can effectively help the skin to achieve the effect of moisturizing and relieve the dry and water-deficient condition of the skin, is added with components such as grease and the like to lock the moisture and nutrients of the skin, and can cover the surface of the skin to form an oily protective film to effectively lock the moisture and nutrients. Particularly, in autumn and winter, the water loss on the face of people is accelerated, the face cream is needed to replenish water and moisturize the face, so that the skin is kept in a tender and soft state, and the stimulation of impurities and dust in the external environment to the skin can be prevented. Based on the above, the active ingredients with whitening effect are wrapped in the skin-care cream, so that the requirements of people with different skin types on moisturizing, whitening and the like can be well met.
