Essence oil capable of repairing damaged sebum film and damaged cuticle and preparation method thereof

Abstract

The invention discloses essence oil capable of repairing damaged sebum film and damaged cuticle. The essence oil is prepared from the following raw materials in parts by weight of 0.1 to 20 parts of meadowfoam seed oil, 5 to 25 parts of squalane, 20 to 55 parts of macadamia integrifolia seed oil, 0.1 to 10 parts of tocopherol, 0.1 to 10 parts of sphingolipids, 0.1 to 10 parts of ceramide 2, 0.1 to 10 parts of ceramide 3, 0.1 to 10 parts of ceramide 4 and 0.1 to 10 parts of ceramide 6II. The essence oil disclosed by the invention can well simulate the structures of a human body sebum film and a cuticle to form a protective barrier covering the outermost layer of skin; And by matching with a ceramide compounding technology, a lipid part in keratinocytes in a cuticle can be well filled, so that the skin barrier is completely repaired, external invasion is resisted, the greasy feeling of most closed grease on the market is improved, the spreadability is better than that of common skin care oil, and the skin feeling is fresh and cool.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and more specifically relates to an essential oil capable of repairing damaged sebum membrane and stratum corneum and a preparation method thereof. Background technique [0002] The skin barrier is the protective barrier covering the outermost layer of the skin, mainly composed of the sebum membrane and the stratum corneum. It plays the role of maintaining skin moisture, preventing water evaporation in the body, and resisting the invasion of foreign substances from the outside world. Therefore, whether the sebum membrane is sound and whether the stratum corneum is arranged neatly determines the moisturizing ability and resistance ability of the skin barrier. However, excessive cleaning, skin PH imbalance, dry skin and other problems will damage the health of the sebum membrane and stratum corneum, causing the moisture in the skin to escape, and the skin will be dry, dull, chalky, sensiti...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the products on the market for repairing damaged sebum membrane and stratum corneum are mainly water-based or oil-in-water products, most of which are polyols, glycerin, and mineral oil. The ingredients are not natural, and most of them come from industrial sources. , The oil extracted from petroleum, and the use of preservatives and emulsifiers has certain irritation to the damaged skin barrier, and the effect of repairing the damaged sebum film and cuticle is slow

At the same time, the sebum membrane and stratum corneum on the surface of the skin are a delicate balance system, too much oil and too little oil will not work, and a single water agent or oil-in-water product cannot simulate the structure of the skin barrier

[0004] As a high-melting point lipid substance, ceramide, the raw material for repairing damaged sebum membrane and stratum corneum, is difficult to add to a single water agent or oil-in-water system, and the effective content added is also very limited, which will not only affect the excellent skin of ceramide Barrier repair effect, and poor stability

At the same time, lacking the synergistic effect of fatty acids, cholesterol, etc., a single ceramide component is difficult to repair the damaged sebum membrane and stratum corneum

[0005] Therefore, in order to solve the problems of most of the non-natural ingredients in the existing cosmetics, the structure of the skin barrier cannot be simulated, the addition of ceramide is limited, the stability is poor, and the ingredients are single, how to develop a compound containing pure vegetable oil and ceramide with oil Soluble plant extracts as active ingredients can repair sebum membrane and cuticle damaged essence oil and its preparation method is a problem that those skilled in the art need to solve urgently
