Description

Essence emulsion composition with moisturizing and relieving effects and preparation method and application thereof

Technical Field

The invention relates to a skin care product and a preparation method and application thereof, belongs to the technical field of daily chemicals, and particularly relates to an essence emulsion composition with moisturizing and relieving effects and a preparation method and application thereof.

Background

Moisturizing is a cosmetic project which is very important for people nowadays, and when the skin lacks moisture, a series of skin problems such as skin dryness, wrinkles, aging and the like can occur, so moisturizing is the most important thing in skin care, and when the skin has sufficient moisture, the skin can look finer and smoother and has young vitality.

Skin moisture loss is generally related to environmental factors, and when the ambient temperature is too high, dryness or wind is strong, the skin loses water seriously. How to effectively moisturize and moisturize the skin needs to be solved by starting from a moisturizing system of the skin.

Firstly, the surface of the cuticle in the skin moisturizing system is a sebaceous membrane which is formed by emulsifying grease secreted from sebaceous glands, lipid produced by corneocytes, sweat secreted from sweat glands and desquamated corneocytes at low temperature and forming a protective membrane on the surface of the skin, and the protective membrane covers the surface of the cuticle of the skin and reduces water evaporation. Secondly, intercellular lipids, which are regularly arranged, can retain intercellular water and block natural moisturizing factors to avoid water loss. Finally, the natural moisturizing factor can combine with water in the horny layer to play a role in absorbing and storing water, so that the horny cells are full of water, and the horny layer becomes finer and softer.

The skin care products at the present stage mainly have several problems that only water replenishing effect is needed and moisture retention is lacked, or moisture retention components are not comprehensive enough and only can act on one part in the moisture retention link, and the skin care products also have components harmful to skin barriers in order to enable the effective components to be better used in a transdermal manner.

Therefore, how to select proper components and scientifically compound the components together can play a role in each link of a human skin moisturizing system, so that the comprehensive moisturizing effect is achieved, and the technical problem which needs to be solved by technical personnel in the field is solved urgently.

Detailed Description

The invention discloses an essence milk composition with moisturizing and relieving effects and a preparation method thereof. The essential milk composition mainly comprises the following components: panthenol, inositol, lactobacillus fermentation lysate, and Codium spinulosum extract. The skin moisturizing and soothing lotion has the effects of moisturizing, repairing skin barriers and relieving local inflammation of skin, and in addition, the four components with the moisturizing and soothing effects can achieve the synergistic moisturizing and soothing effects when used simultaneously.

Wherein, the panthenol mainly plays the roles of an emollient and a humectant in the skin care product, and the relatively small molecular weight of the panthenol can effectively permeate into the horny layer of the skin, transport water to the horny layer and maintain the water content of the skin.

Inositol has the main functions of a moisturizing agent and a skin penetrating agent in the skin care product, has good transdermal permeability, can also promote the penetration of other components, and has the effects of moisturizing and conditioning the skin. When inositol and panthenol are used simultaneously, the skin's ability to absorb water and permeate can be improved, and the content of hyaluronic acid in the skin can be increased, which has a non-sticky skin feel compared with the conventional moisturizing ingredient glycerin.

The lactobacillus fermentation lysate is rich in lactic acid and sodium lactate, is a main water-soluble acid in human Natural Moisturizing Factors (NMF), has strong hygroscopicity, effectively enhances the hydration of the horny layer, prevents the water loss of the skin and supplements the deficiency of NMF in intercellular substance.

In addition, the lactobacillus fermentation lysate contains polypeptide compounds with bacteriostatic action such as lactein, and the like, is a natural bacteriostatic agent and has sedative and soothing effects on the skin.

The codium spiniferum extract can supplement moisture for skin, improve skin dryness and water shortage, improve skin moisturizing capability, and is rich in various active ingredients, so that the codium spiniferum extract can supplement nutrition for skin, adjust the resistance of cells to the outside, promote the metabolism of cells, and reduce skin water loss caused by external stimulation.

The invention creatively combines the four moisture-keeping and relieving functional components, and can play the roles of moisturizing the skin, repairing the skin barrier and relieving local skin inflammation at the same time. When the panthenol, the inositol, the lactobacillus fermentation lysate and the codium spinulosum extract are compounded and combined at the same time and are applied to the essential milk, the normal operation of a moisturizing system of the skin can be maintained.

The present invention is illustrated by the following examples, which are provided for the purpose of further illustration only and are not intended to limit the scope of the present invention.
