Background

The skin of a person has five major categories of dryness, oiliness, mixability, neutrality and sensitivity, the existing skin care product has a single formula and fixed component proportion, and can only be suitable for one skin type, and the audience range is limited; on the other hand, facial skin of people is in different states due to different regional climates, different temperatures and humidities and different indoor environments, in addition, China is large in land and wide in width, the climate difference between the south and the north is very large, the climate in the north is dry, the climate in the south is wet, the existing skin care product cannot be flexibly prepared according to the climate of the current region where a consumer is located, the use flexibility is poor, and the applicable region is limited.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides the self-prepared two-component essence cream and the preparation method thereof, and solves the problem that the existing skin care product cannot be adjusted according to the skin state of a user.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a self-prepared two-component essence cream comprises a basic moistening gel component and an enhanced maintenance essential oil cream component, wherein the enhanced maintenance essential oil cream component is represented by I, the basic moistening gel component is represented by II, and the enhanced maintenance essential oil cream component and the basic moistening gel component are isolated from each other.

The component (I) of the essential oil cream for enhancing and maintaining is composed of the following raw materials in percentage by weight:

A_Ⅰ0.5-1.5% of macadamia nut seed oil, 1.5-2.5% of jojoba seed oil, and 0.5-1.5% of polyDimethyl siloxane, 1.5 to 2.5 percent of isononyl isononanoate, 1 to 2 percent of squalane, 0.05 to 0.15 percent of antioxidant, 1.5 to 2.5 percent of emulsifier and 1 to 2 percent of thickening agent,

the macadimia nut seed oil is rich in minerals, proteins and various unsaturated fatty acids, can be used for conditioning aged or dry skin, and has the greatest advantages of mild oiliness, no stimulation to the skin, good ductility and capability of softening and activating the skin; on the other hand, the macadamia nut seed oil also has the function of base oil as the component of the enhanced maintenance essential oil cream, because the component of the enhanced maintenance essential oil cream comprises various essential oils, and the macadamia nut seed oil has good permeability and high solubility to various essential oils, is good base oil, and can bring certain greasy skin feeling.

The jojoba seed oil is composed of single unsaturated fatty acid and single unsaturated fatty alcohol, the hydrophile/lipophile balance value of the jojoba seed oil is about 6, and the jojoba seed oil can be completely mixed with the surface sebum of the skin, so that the jojoba seed oil can easily enter the oil phase of the skin and be combined with the oil phase to form a layer of oil-free film on the skin, but pores and hair follicles are still in an open state, and the jojoba seed oil has the function of lubricating and caring the skin.

The polydimethylsiloxane has the function of resisting ultraviolet radiation, but has obvious physiological inertia and is easy to separate out, so the inventor chooses to add the isononyl isononanoate to solve the problem that the polydimethylsiloxane is easy to separate out. The isononyl isononanoate has excellent compatibility with the polydimethylsiloxane, can be used as a stabilizing agent and a coupling agent of the polydimethylsiloxane, has a polymethyl branched chain structure, is low in viscosity, has fresh skin feel, is an excellent emollient, and has an effect as an emollient in the invention.

different moisturizing agents have different moisturizing mechanisms, such as moisture blocking, moisture absorption, moisturizing and the like, and in practical production application, only one moisturizing agent is used, so that an ideal moisturizing effect cannot be achieved, and therefore, the B component_ⅠThe phases are hydrophilic moisturizers that differ by combining different moisturizing mechanisms to achieve the desired moisturizing effect.

The molecule of the glycerin contains three-OH groups, and the glycerin can form hydrogen bonds with water molecules to restrain water, so that the glycerin plays a good role in absorbing moisture and preserving moisture, has an obvious moisturizing effect on human skin, and also has a function of increasing the solubility of other components.

The addition of the glycerin results in the invention bringing less pleasant greasy feeling to the skin in a semi-dry state, and the glyceryl polyether-26 is a glycerin polymer of 26 EO, and the moisturizing effect is stronger than that of the glycerin even in a low addition amount, so the invention improves the sticky skin feeling caused by the addition of the glycerin by adding the glyceryl polyether-26 in a proper amount.

The betaine is a natural amino acid humectant, and the moisturizing mechanism of the betaine is as follows: the betaine can obviously inhibit the process by absorbing the moisture in the deep layer of the skin to the surface layer with water shortage, so that the surface layer of the skin also contains sufficient moisture, the problem of drying of the skin care product after being smeared can be avoided, and the betaine also has an antiallergic effect.

The sodium hyaluronate realizes moisture preservation by enhancing the water absorption and water binding capacity of the skin stratum corneum, and has the outstanding characteristics of film forming property and lubricity, and a breathable hydrated elastic film can be formed after the sodium hyaluronate acts on the skin surface.

C_ⅠPhase 1-5% cyclopentadimethylsiloxane. A is described_ⅠPolydimethyl silicon in phaseAlthough the problem of easy separation of siloxane is improved by the isononyl isononanoate, the polydimethylsiloxane actually has the problem of heavy and greasy skin feel when the polydimethylsiloxane is applied, and the cyclopentasiloxane belongs to water-thin (water-thin) organic silicon and is unstable in property, so that the polydimethylsiloxane is helped to volatilize after being pushed away, the skin can not feel burdens, and the problem of heavy and greasy skin feel when the polydimethylsiloxane is applied is solved.
