Further, the emulsifier is olive oil extract, and the olive oil extract comprises cetearyl olive oleate and sorbitan olive oleate.

Further, the stabilizer is a mixture of p-hydroxyacetophenone, 1, 2-hexanediol and propylene glycol.

Furthermore, the mass percentages of the p-hydroxyacetophenone, the 1, 2-hexanediol and the 1, 3-propylene glycol in the skin softening particle invisible hand cream are respectively 0.5-1%, 0.05-2% and 2-5%.

Further, the compound plant whitening agent comprises niacinamide, mulberry bark extract, and madecassoside.

Further, the mass percentage of the nicotinamide in the composite plant whitening agent is 5-15%.

The preparation method of the nourishing and repairing emulsion comprises the following steps:

1) putting the shea butter, the thickening agent and the emulsifying agent in the formula ratio into an oil phase pot, heating to 75-80 ℃, and uniformly stirring to obtain an oil phase substance;

2) putting the ceramide composite liquid, the sodium hyaluronate, the glucan, the composite plant whitening agent and water in a formula ratio into an emulsifying pot, heating to 75-80 ℃, and uniformly stirring to obtain moisturizing liquid;

3) pumping the oil phase substances in the step 1) into an emulsifying pot, starting homogenizing, uniformly stirring, cooling to 30-40 ℃, and adding tocopherol acetate with the formula amount to obtain a nourishing and repairing emulsion primary liquid;

4) adding the stabilizer with the formula amount into the hand cream primary liquid, and uniformly stirring to obtain the hand cream.

The invention has the beneficial effects that:

the ceramide 3 in the ceramide composite liquid of the nourishing and repairing emulsion is a lipid substance, has a structure similar to that of a substance forming a skin stratum corneum, can quickly permeate into the skin, helps the skin natural protective layer to renew, can promote the balance of natural hydration, and is combined with water in the stratum corneum to form a net structure to lock water. Ceramide 3 has a good effect on skin moisturizing and repairing, is an important skin-activating component in the horny layer, and can enhance the skin barrier, rebuild cells, and form an effective barrier to prevent water loss and reduce the influence of the external environment. More ceramide 3 is particularly needed in irritated skin and it has been shown that rubbing a product containing a ceramide 3 component reduces redness and skin moisture loss, acts to enhance the skin barrier and helps the damaged skin to relieve dry conditions.

The nourishing and repairing emulsion contains the composite plant whitening agent containing the nicotinamide. Based on the characteristic, the application of the niacinamide in the field of cosmetics is further extended, and the niacinamide has the effects of reducing the generated and precipitated melanin, blocking the transfer of the melanin to surface layer cells, accelerating cell metabolism, accelerating the shedding of melanin keratinocytes and the like besides the traditional whitening effect. The nicotinamide can maintain the moisture content of the skin and promote microcirculation of the dermis. Niacinamide also greatly reduces or eliminates skin aging phenomena such as wrinkles, scaling, large pores, etc., reduces free radical damage to the skin, and serves to prevent aging, repair skin, and reduce facial darkness. Nicotinamide is widely used for treating photosensitive dermatitis, acne and the like.

The nourishing and repairing emulsion contains hydrogenated polyisobutene which is a lipid closest to sebum of a human body and is extracted from the liver of deep sea shark. The hydrogenated polyisobutene can adjust water-oil balance, form a natural skin protection barrier for skin, and has super-strong oxidation resistance and ultraviolet resistance functions. The hydrogenated polyisobutene can effectively protect the skin from external damage, and the skin is tender, smooth and elastic.

The nourishing and repairing emulsion contains sodium hyaluronate which is a skin conditioner. Sodium hyaluronate is an acidic mucopolysaccharide, naturally exists in corneal skin, and can absorb 1000 times of water of the corneal skin so as to achieve the purpose of retaining skin water and preventing water from losing through epidermis. When the skin is damaged, the sodium hyaluronate is used as a barrier to repair, so that the skin does not feel dry, the skin luster is increased, the skin nutrition metabolism can be improved, the skin is soft and smooth, the wrinkles are removed, the elasticity is increased, the skin aging is prevented, and the sodium hyaluronate is a good transdermal absorption enhancer while keeping moisture. Can be used in combination with other nutritional ingredients to promote nutrient absorption.

The nourishing and repairing emulsion contains the emulsifier, the thickener and the stabilizer, so that the nourishing and repairing emulsion has good physical stability, and effective moisture retention and whitening components in the nourishing and repairing emulsion can be uniformly dispersed.

The nourishing and repairing emulsion provided by the invention has the advantages that all components are matched with each other, melanin is inhibited, the effects of whitening, long-acting moisturizing and accelerating the regeneration of aged stratum corneum cells are achieved, and the emulsion has good safety and stability.
