Description

Technical Field

[0001] The invention relates to the field of sunscreen cosmetics, and in particular to a spray-type two-phase moisturizing essential oil and a preparation process thereof. Background Art

[0002] As the pace of life in today's society accelerates, the environment is also undergoing tremendous changes. Ultraviolet rays, infrared rays, electromagnetic radiation, haze and the mental stress brought about by people's lives have been quietly affecting our lives and causing great harm to our skin condition.

[0003] The skin is the largest organ in the human body, accounting for 5% to 15% of the body weight, with a total area of ​​1.5-2 square meters. The thickness varies from person to person or from part to part, ranging from 0.5 to 4 mm. The skin covers the whole body, protecting various tissues and organs in the body from physical, mechanical, chemical and pathogenic microorganisms. The skin has two barrier functions: on the one hand, it prevents the loss of water, electrolytes and other substances in the body, and on the other hand, it prevents the invasion of harmful substances from the outside of the tissue, maintains the stability of the human body's internal environment, and plays an important protective function physiologically. At the same time, the skin also participates in the body's metabolic process. Increased urea nitrogen content in the human body will lead to accelerated fatigue.

[0004] The skin is inevitably exposed to pollutants in the environment every day, and it has to endure long-term damage from them, resulting in problems such as dryness and aging of the skin. Most body care products on the market have poor moisturizing properties and use thick creams that feel heavy on the skin. They are not convenient to use by applying, have a poor skin feel, and are generally packaged in a few hundred milliliters of a squeeze bottle that is difficult to carry. Therefore, it is of great application value to develop a spray-type essential oil that is easy to use, has strong moisturizing properties, and is easy to carry. Summary of the invention

[0005] The purpose of the present invention is to solve the problems raised by the existing background technology and to achieve the above-mentioned purpose of the invention. The present invention provides the following technical solutions: a spray-type two-phase moisturizing essence oil, comprising a water phase and an oil phase, wherein the mass ratio of the water phase to the oil phase is 10:6-7, and the mass percentages of the water phase and the oil phase are:

[0006] Aqueous phase:

[0007] Moisturizer 9.5% to 14%;

[0008] Composite plant antiallergic agent 0.6% to 1.2%;

[0009] Preservatives 0.1% to 1.0%;

[0010] Disodium EDTA 0.01%~0.05%;

[0011] Sodium chloride 0.5% to 1%;

[0012] Deionized water 44.85%~54.19%;

[0013] Oil phase:

[0014] Emollient 35% to 40%;

[0015] Flavor 0.1%~1.0%.

[0016] The moisturizing agent is at least one of 1,3-butylene glycol, 1,2-hexanediol, glycerin, allantoin, trehalose, betaine, hydroxyethyl urea, squalane and mahogany seed oil.

[0017] The composite plant antiallergic agent is at least one of kava extract, purslane extract, bitter melon extract, corn silk extract and glycyrrhiza glabra root extract.

[0018] The preservative is at least one of p-hydroxyacetophenone, phenoxyethanol, ethylhexylglycerin and caprylhydroxamic acid.

[0019] The emollient is at least one of neopentyl glycol dicaprate, propylene glycol dicaprylate / dicaprate, dicaprylyl carbonate, and isododecane.

[0020] The essence is Costin cherry blossom extract.

[0021] In order to achieve the above-mentioned purpose of the invention, the present invention provides another technical solution: a preparation process of a spray-type two-phase moisturizing essence oil, comprising the following steps:

[0022] (1) Pour deionized water into a stirring pot, add moisturizer, and then heat to 85°C, continue stirring and keep warm for 30 minutes;

[0023] (2) cooling the stirring pot to 55° C., adding sodium chloride, composite plant antiallergic agent, preservative, 1,2-hexanediol, and disodium EDTA in sequence, and stirring evenly to obtain a mixture A;

[0024] (3) Weigh the oil phase components, add them into a stirring pot in sequence, and stir them evenly to obtain a mixture B;

[0025] (4) The mixture A and the mixture B are filtered through 400 meshes respectively, and then filled with liquid at a mass ratio of 10:6-7 and allowed to stand to prepare an essential oil with a water-oil phase balance.

[0026] The present invention contains a composite plant anti-allergic agent, which has the effects of anti-allergic, anti-inflammatory, soothing and repairing, strengthening the skin barrier, improving the skin's resistance to external stimuli, and reducing the occurrence of allergic reactions.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] It is non-irritating to the skin, will not cause skin allergies, and has good moisturizing and refreshing properties. It is distributed on the skin through spray when used, is easy to carry, and is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
