Description
Technical field
The present invention relates to daily-use chemical industry technical field, especially relate to a kind of orange oil microcapsule and its preparation method and application.
Background technology
Chapped skin is the skin problem often occurred autumn and winter.Autumn and winter season, cold weather was dry, and the easy hydropenia of skin of human body, drying and produce a series of skin problem, show as skin rubefaction, desquamation, dry pruritus etc.
Now there are some researches show, chapped skin, is mostly because skin natural moisture preserving structure disequilibrium, and refer to that the skin of epidermis loses large quantity of moisture, the moisture in skin corium still has little time to supplement, and causes epidermis dry and cracked.With advancing age, skin aging, its moisture-keeping function and barrier function weaken gradually, and nature moisturizing factor content reduces; Environmental factors, as long air conditioner surroundings; Diet sleep habit, as monophagia, drinking-water is few, and insomnia etc. all can cause the skin unbalance of the series such as the drying of skin.Therefore, a lot of people has brought into use cold cream frost to maintain skin now, and life-time service can keep skin wet, soft, glossy, well moistens and care to skin in autumn and winter season.
Orange oil (neroli oil), extract from fruit, there is very dazzling warm sunlight speciality, gentle sweet perfume (or spice) breath, intense strain and pressure can be expelled, improve insomnia caused by anxiety, owing to containing a large amount of VC in Fructus Citri sinensis, energy preventing cold, pH-value skin being had to moisturizing effect, balance skin, the formation of help collagen protein.Go if directly orange oil is added to inside product, easily there is volatilization and make effective ingredient some lost in orange oil, be lost the special role of orange oil in storage process simultaneously.Although orange oil is added in cold cream frost by prior art, its effective acting time is general shorter, mainly or because of the easy volatilization in storage process of the elements such as orange oil causes.
