Description

Mild and eye-pasting-free cleansing oil and preparation method thereof

Technical Field

The invention relates to the field of A61K8/891, in particular to a mild and eye-free cleansing oil and a preparation method thereof.

Background

Cosmetics play an increasingly important role in daily life of people, but after facial makeup, residual cosmetics can cause pore blockage of facial skin, and cause dysregulation of skin oil and water oil secretion, thereby causing skin problems such as acne, comedo, blackhead and the like which are puzzled. Meanwhile, the residual cosmetics have great damage to skin, if the skin cannot be cleaned up in time, the cosmetics enter hair follicles along with the breathing of pores to form cysts, and the problems of difficult cleaning out of the skin surface layer exist for a long time, so that the cleansing link of the skin is very important, but a lot of cleansing oil is not mild enough and can stick to eyes in the cleaning process, so that the cleansing oil which is mild and does not stick to the eyes needs to be developed.

CN110623861a discloses a cleansing oil which does not form oil film residue, and adopts a combination of sorbitan trioleate and sorbitol polyether-30 tetraoleate to solve the problem of "pasting eyes" of the cleansing oil, however, the oily system is very easy to take away the grease on the skin surface, and the loss of the lipid barrier of the skin is caused by long-term use, and the skin is dried instead.

CN111110599a discloses a transparent cleansing cream, a preparation method thereof and a double-ended product, wherein the preparation raw material contains ethylhexyl palmitate and hydrogenated polyisobutene, has the effects of environmental protection and beauty, but has poor removal effect on some waterproof and oil-proof powerful makeup.

Therefore, the problems of dryness and greasiness brought by an oily system can not be balanced on the basis of efficient makeup removal in the prior art.

Disclosure of Invention

The first aspect of the invention provides a mild and eye-non-stick cleansing oil, which is prepared from the following raw materials in parts by weight: 8-15 parts of emulsifying agent and 75-85 parts of oil ester.

As a preferred embodiment, the emulsifier includes at least one of a glyceryl stearate type emulsifier and a glyceryl polyoxyethylene ether type emulsifier.

As a preferred embodiment, the emulsifier includes at least one of glyceryl monostearate, glyceryl distearate, glyceryl tristearate, PEG-3 glyceryl isostearate, PEG-20 glyceryl triisostearate, ethoxylated glyceryl tristearate, diglycerol polyoxyethylene ether malate, glycerol polyoxyethylene ether cocoate.

As a preferred embodiment, the glyceryl tristearate is PEG-3 glyceryl isostearate, PEG-20 glyceryl triisostearate.

As a preferred embodiment, the weight ratio of the PEG-3 glyceryl isostearate to the PEG-20 glyceryl triisostearate is (1-3): (10-15).

In order to reduce the problem of "sticking to the eyes", it is further preferred that the weight ratio of PEG-3 glyceryl isostearate to PEG-20 glyceryl triisostearate is 2:13.

the makeup removing product in the prior art is mainly prepared by dissolving the makeup removing product in an emulsifying agent in an emulsifying mode, and then generating milky emulsion after dissolving the makeup removing product in water, so that the problems of eye irritation pain, incapability of opening eyes and blurred short-time vision caused by careless eyes can be caused, and the makeup removing of eyes is seriously influenced.

The applicant has found that the choice and amount of emulsifier has a direct relationship to the problem of "sticking to the eyes". PEG-3 glyceryl isostearate and PEG-20 glyceryl triisostearate are selected as emulsifying agents, and the weight ratio of the two is (1-3): (10-15), the prepared makeup removing product does not generate the phenomenon of 'sticking eyes', the surface of the skin is clean, the skin has no irritation effect on eyes, and the problem can not be solved when the PEG-20 glyceryl triisostearate is singly used.

The applicant speculates that the reason may be that the polymerization degree of PEG-3 isostearic acid glyceride is lower, and the PEG-3 isostearic acid glyceride can be synergistically acted with PEG-20 triisostearate after a small amount of PEG-20 triisostearate is added, oil stains are rapidly wrapped in an oil-in-water mode after oil-in-water makeup is dissolved, the structure of a water layer is thicker and more compact, the hydrophilicity after water contact is stronger, the solubility after water contact is higher, and compared with the prior art, the content of the irritant oil stains after dilution and emulsification can be remarkably reduced, so that the phenomenon of 'sticking eyes' is remarkably reduced. However, the applicant found that the addition of PEG-3 glyceryl isostearate, PEG-20 glyceryl triisostearate resulted in a product that turned yellow over time, with poor appearance.

As a preferred embodiment, the cleansing oil further comprises the following raw materials in parts by weight: 3-15 parts of humectant and 0.1-2 parts of auxiliary agent.

As a preferred embodiment, the oil ester includes at least one of ethylhexyl palmitate, hydrogenated polyisobutene, caprylic/capric triglyceride, 2, 3-dihydroxypropyl stearate, neryl butyrate, ditridecanoyl sebacate.

Preferably, the oil esters include ethylhexyl palmitate, hydrogenated polyisobutene, caprylic/capric triglycerides.

Preferably, the weight ratio of ethylhexyl palmitate, hydrogenated polyisobutene, caprylic/capric triglyceride (1-3): (2-5): (1-3).

In order to improve the cleansing effect, it is further preferable that the weight ratio of ethylhexyl palmitate, hydrogenated polyisobutene, caprylic/capric triglyceride is 2:4:3.

applicants found that ethylhexyl palmitate, hydrogenated polyisobutene, caprylic/capric triglyceride in weight ratio (1-3): (2-5): (1-3) can obviously improve the makeup removing effect after the compounding, has good cleaning effect on the makeup with stronger water resistance and heavier color of eyes and lips, does not generate tight feel after the makeup removing and cleaning,

the applicant speculates that the reason is probably that the three kinds of grease have proper HLB values after being compounded, can rapidly take away the oil-soluble makeup components on the skin surface, has small cleaning and adsorbing effects on the self-contained lipid components of the skin, and can not take away the lipid components on the skin surface excessively under the combined action of the emulsifying agent, thereby achieving the effect of efficiently removing makeup but not tightening, being capable of being used for a long time and not damaging the skin barrier.

As a preferred embodiment, the humectant comprises at least one of olive oil, calendula oil, rose essential oil, grape seed oil, jojoba oil, sweet almond oil, avocado oil.

As a preferred embodiment, the moisturizer comprises olive (latin name: canarium album (lour.) raeusch.) oil, calendula (latin name: calendula officinalis l.) seed oil, rose (la Ding Xueming: rosa rugosa thunb.) essential oil, the weight ratio of olive oil, calendula seed oil, rose essential oil is (4-9): (1-2): (2-4).

The applicant intends to add plant essential oil to improve the moisturizing effect of the cleansing oil, but found that olive oil, calendula seed oil and rose essential oil are in weight ratio of (4-9): (1-2): (2-4) can lead the composition to have long-term high-low temperature stability, and unexpectedly solves the problem of easy yellowing caused by the emulsifier.

The applicant speculates that the reason is probably that the addition of the three essential oils can improve the compatibility of the makeup removal oil layer, especially the addition of the multivitamins in the olive oil can achieve the colloid bundle effect of the system together with the emulsifier in the system, so that the emulsifier components which are easy to yellow are combined together with the self structure by intermolecular force, and under the synergistic protection of calendula oil and rose essential oil, the favorable intermolecular effect can be maintained under the conditions of long-term high temperature, low temperature and circulation temperature, and the yellowing and precipitation are not easy to occur.

As a preferred embodiment, the auxiliary agent includes at least one of butyl hydroxy anisole, lecithin and vitamin E.

In a second aspect, the present invention provides a method for preparing a mild, eye-friendly cleansing oil, the method comprising: mixing the oil and the emulsifier uniformly, continuously adding the humectant and the auxiliary agent, and stirring uniformly.

Compared with the prior art, the invention has the following beneficial effects:
