The invention utilizes the pure physical sun-screening agent to form the anhydrous sun-screening gel, and although the gel is a full-oil formula, the formed gel has excellent skin feel, higher sun-screening value and better water resistance.
Description
Technical Field
The invention relates to a sun-screening agent and a preparation method thereof, in particular to a sun-screening anhydrous gel of a pure physical sun-screening agent and a preparation method thereof.
Background
Under the strong irradiation of ultraviolet rays, the skin is easy to be inflamed and burned, and even pigmented skin cancer and other problems are easy to occur. In order to prevent skin from being sunburned and sunburned, not only physical shielding by using sun-screening clothes but also blocking or absorbing ultraviolet rays by applying a sun-screening product or the like can be used.
The sun-screening products on the market at present mainly comprise the following products:
1. sunscreen oils of the pure oil phase system: most sunscreens are oil soluble and therefore compatible with most polar oils to form homogeneous systems. However, the sunscreen oil has thick and greasy skin feel, so that the sunscreen oil is not common in domestic markets; and such sunscreen products are generally free of physical sunscreens;
2. a sun-proof rod: the sun-screening stick is similar to sun-screening oil, and is different in that the sun-screening stick is thickened and formed by an oil-phase thickener, has certain hardness, but is thick, greasy and oily, and has less domestic market audience;
3. sunscreen spraying: the product spray contains a large amount of alcohol or propellant, and is internally mixed with a sunscreen agent, so that inhalation danger exists, certain harm is caused to human bodies, and the other defect is that the due sunscreen effect cannot be achieved easily due to insufficient spray amount in the using process of consumers. The european union stipulates that solid nanomaterials cannot be used in products that risk inhalation, so spray products containing physical sunscreens are almost non-existent;
4. aqueous oil-in-water or water-in-oil sunscreen products: such products may contain physical sunscreens alone or in combination with chemical organic sunscreens. The products have the most popular audience in the market due to the light and thin skin feel. But the defect is that the utility model can be easily washed away when meeting water in the beach, swimming pool and other occasions.
Physical sunscreens have better human safety values than chemical sunscreens because they are not absorbed by the skin, and therefore the development of sunscreen products containing physical sunscreens is also becoming an important issue.
Chinese patent application 201610046186.3 discloses a sunscreen cream comprising 3-9 parts of stearic acid and Al2O33-11 parts of solid particles, 2-4 parts of cetyl alcohol, 5-10 parts of isopropyl palmitate, 2-6 parts of lanolin, 1-3 parts of methyl paraben, 2-8 parts of triethanolamine, 5-10 parts of glycerol, 3-6 parts of EDTA (ethylene diamine tetraacetic acid), 2-4 parts of azone, 2-6 parts of xanthan gum, 1-5 parts of glyceryl ether stearate, 4-12 parts of superfine titanium dioxide, 8-16 parts of zinc oxide, 1-2 parts of pigment, 5-8 parts of spice, 1-3 parts of anti-inflammatory traditional Chinese medicine and 50-65 parts of deionized water. Although the patent application contains ultrafine titanium dioxide, the product can produce partial physical sun-screening effect, on one hand, the product is in the form of cream, has poor skin feel and is not easy to be applied uniformly, and on the other hand, the product is aqueous, is in the form of oil-in-water or water-in-oil, is easy to wash away when meeting water and shearing force, and is not water-resistant.

Disclosure of Invention
The invention aims to provide an anhydrous sunscreen gel of a pure physical sunscreen agent, which is water-resistant, non-sticky when being applied, and has better skin feel and higher sunscreen value.
In one aspect, to achieve the above objects of the present invention, the present invention provides an anhydrous sunscreen gel containing a physical sunscreen agent, wherein the anhydrous sunscreen gel comprises the following components by weight:
10% -50% of a physical sunscreen agent,
0.1 to 5 percent of dispersant,
1.0% -9.0% of silicone elastomer,
0 to 5 percent of oil phase thickening agent,
40% -80% of fat, and
0 to 5 percent of active matter,
wherein, the adopted physical sun-screening agent is nano or non-nano titanium dioxide and/or zinc oxide, the initial particle size of the adopted nano titanium dioxide is within the range of 10-40 nm, the initial particle size of the adopted nano zinc oxide is within the range of 15-50 nm, and the initial particle size of the adopted non-nano titanium dioxide or zinc oxide is within the range of 100-200 nm; the inventors have found that the use of sufficiently fine titanium dioxide and/or zinc oxide only contributes to the formation of a dense, sun-protective film;
the adopted dispersant is a substance which has a dispersing effect on the physical sunscreen agent in the form of powder in the adopted grease and can prevent the powder from aggregating;
the oil phase thickener is montmorillonite and/or hectorite modified by lipophilic group, and is 0% only when the content of siloxane in the oil reaches or exceeds 80%; otherwise, an oil phase thickening agent is added;
the adopted grease is used for dissolving and/or dispersing the adopted oil-soluble sun-screening agent, the organic silicon elastomer and the oil phase thickening agent;
the active substance is oil-soluble and effective component used in cosmetic.
The anhydrous sunscreen gel disclosed by the invention has good skin feel, is not sticky when being applied, and does not generate oily light.
It should be noted that, in the market, silicone elastomers are often present in a dispersed form such as a gel form in which they are dispersed in fats and oils, and oil phase thickeners are also often present in a dispersed form such as a gel form in which they are dispersed in fats and oils, but it is impossible to distinguish fats and oils from silicone elastomers themselves or oil phase thickeners themselves because they are adjusted by adding extra fats and oils or elastomers in practice. Therefore, this is differentiated in the present invention for clarity of explanation. For example, if a silicone elastomer dispersion form or an oil phase thickener dispersion form is purchased, it is converted into the corresponding silicone elastomer + grease or oil phase thickener + grease.
In the anhydrous sunscreen gel of the present invention, the physical sunscreen agent used is preferably treated with one or more surface treatment agents selected from the group consisting of: silica, aluminum hydroxide, polydimethylsiloxane, triethoxyoctylsiloxane, hydrogenated polydimethylsiloxane, silicone resin, dimethoxydiphenylsilane/triethoxyoctylsilane crosslinked copolymer, stearic acid, and aluminum stearate. The main advantages of surface treatment of physical sunscreens are that they can block the photocatalytic effect of fine particles and that they are not easily aggregated and easily dispersed in the oil phase. After the fine particles reach the nanometer level, titanium dioxide and zinc oxide have the photocatalysis function, and most negative effects can be eliminated after the surface treatment is carried out on the surfaces of the titanium dioxide and the zinc oxide; in addition, the particle size is small, so that the particles are easy to aggregate into a mass, and the particles are not easy to aggregate after surface treatment, thereby being beneficial to uniform dispersion in a formula.
In the anhydrous sunscreen gel of the present invention, the silicone elastomer is preferably one or more selected from the following group: polydimethylsiloxane crosspolymers and polydimethylsiloxane/vinyl polydimethylsiloxane crosspolymers. The organic silicon elastomer has two main functions of thickening and regulating skin feel of a system, and a pure physical sun-screening formula can contain more siloxane as grease, so the organic silicon elastomer can be used as a thickening agent of the system, and on the other hand, the organic silicon elastomer is popular, light, matte and not greasy due to excellent skin feel.
The polydimethylsiloxane cross-linked polymer used preferably includes a polydimethylsiloxane cross-linked polymer having a polyethylene glycol or polypropylene glycol chain, such as PEG-12 polydimethylsiloxane/PPG-20 cross-linked polymer, polydimethylsiloxane/bis-isobutyl PPG-20 cross-linked polymer, and the like.
In the anhydrous sunscreen gels of the present invention, the oil phase thickener is one of the key ingredients for forming the gel. If more than 80% of the oil used for forming the anhydrous sunscreen gel is siloxane, the oil phase thickening agent is not added in the formula, namely the oil phase thickening agent is 0%; however, when the used grease contains other grease of non-silicone oil, the grease phase thickener is needed to be added, and the dosage of the grease phase thickener needs to be adjusted correspondingly according to the proportion of other grease in the formula. In the present invention, the lipophilic group in the oil phase thickener used is preferably derived from a C-atom having a single-chain or double-chain structure12-C22Quaternary ammonium salts of (2).
More preferably, in the anhydrous sunscreen gel of the present invention, the oil phase thickener used is disteardimonium hectorite and/or selelammonium hectorite.
In the anhydrous sunscreen gel of the present invention, the dispersing agent is one of the key components for achieving the object of the present invention, because the selection and use of the dispersing agent determine the dispersion degree of the physical sunscreen agent in the whole system, especially grease, and only if the dispersion degree is high or uniform, a better dense sunscreen film can be formed. The dispersant used is preferably one or more selected from the group consisting of: polydimethylsiloxane with polyethylene glycol groups, polydimethylsiloxane with polyglycerol groups, sorbitan isostearate and polyhydroxystearic acid.
Among the above-mentioned dispersing agents, the polydimethylsiloxane having a polyethylene glycol group may be PEG-10 polydimethylsiloxane, PEG-9 polydimethylsiloxane ethyl polydimethylsiloxane and/or cetyl PEG/PPG-10/1 polydimethylsiloxane; the polydimethylsiloxane carrying a polyglyceryl group may be polyglyceryl-3 polydimethylhydroxyethyl polydimethylsiloxane and/or lauryl polyglyceryl-3 polydimethylsiloxyethyl polydimethylsiloxane.
In the anhydrous sunscreen gel of the present invention, the oil or fat used may be one or more selected from the following group: low viscosity polydimethylsiloxanes, octyl polymethylsiloxanes, phenyl trimethicones, diphenyl siloxy phenyl trimethicones, cyclomethicones, C11-C19Linear or branched alkanes, synthetic oils and vegetable oils. Wherein, the adopted low-viscosity polydimethylsiloxane can be polydimethylsiloxane with the viscosity of 2, 5, 6, etc.; c used11-C19The straight-chain or branched alkane of (1) can be isododecane, isohexadecane, hendecane, tridecane, white mineral oil, liquid paraffin and the like; the synthetic oil can be isononyl isononanoate, propylene glycol carbonate, dioctyl carbonate, C12-C15Alkyl benzoate esters of (i), caprylic/capric triglyceride, diisopropyl adipate, isopropyl myristate, isodecyl pivalate, etc.; the vegetable oil can be squalane, avocado oil, jojoba oil, sunflower seed oil, white chinlon oil, etc.
In the anhydrous sunscreen gel of the present invention, the active substances used refer to other functional ingredients commonly used in cosmetics, such as bisabolol having anti-inflammatory and soothing effects, laminaria cuneata extract having anti-photoaging effects, ceramide having repairing effect, etc., which are not listed herein. Of course, the anhydrous sunscreen gels of the present invention may also be free of such actives.
It is to be noted that although the anhydrous sunscreen gel of the present invention is preferably an anhydrous sunscreen gel comprising a pure physical sunscreen agent, i.e. it may be completely free of organic sunscreen agents, it is also possible to add an appropriate amount of organic sunscreen agent to the anhydrous sunscreen gel of the present invention, i.e. the anhydrous sunscreen gel of the present invention may be a system of pure physical sunscreen agents, but the system does not exclude organic sunscreen agents, which may be present together with physical sunscreen agents in the system of the present invention.
As a specific embodiment, the anhydrous sunscreen gel of the present invention comprises the following components:
15% -40% of physical sun-screening agent,
0.5 to 3 percent of dispersant,
2.0% -8.0% of silicone elastomer,
0 to 3 percent of oil phase thickening agent,
50% -80% of fat, and
0% -1% of active substance.
As another specific embodiment, the anhydrous sunscreen gel of the present invention comprises the following components:
20 to 40 percent of physical sun-screening agent,
1.0 to 3 percent of dispersant,
3.0% -8.0% of silicone elastomer,
0 to 1.5 percent of oil phase thickening agent,
50% -70% of fat, and
0% -1% of active substance.
In another aspect, to achieve the object of the present invention, the present invention also provides a method for preparing the above anhydrous sunscreen gel, comprising the steps of:
1) dispersing the adopted physical sun-screening agent and the adopted dispersing agent in part of the adopted grease, and homogenizing and uniformly dispersing to obtain a sun-screening agent dispersion liquid;
2) adding the organic silicon elastomer in a dispersed state into the sunscreen dispersion liquid obtained in the step 1), and uniformly stirring.
In the preparation method of the present invention, the step 1) of homogeneous dispersion must be made uniform to prevent any generation of relatively coarse particles.
If an oil phase thickener is used in the formulation of the anhydrous sunscreen gel, the preparation method step 2) further comprises adding the oil phase thickener in a dispersed state to the sunscreen dispersion obtained in step 1).
The silicone elastomer in a dispersed state can be purchased directly or prepared by the following method: mixing the organic silicon elastomer with the grease, and stirring uniformly to obtain translucent or transparent organic silicon elastomer gel or other dispersed forms.
The oil phase thickener in a dispersed state can also be purchased directly or prepared by the following method: adding the oil phase thickener into oil, and stirring to obtain translucent oil phase thickener gel or other dispersed form.
If the active is used in the formulation of an anhydrous sunscreen gel, the above-described method of preparation further comprises the step of adding the active and stirring it to homogeneity.
The invention forms the anhydrous sunscreen gel by using the pure physical sunscreen agent, not only greatly improves the safety of human bodies (the physical sunscreen agent is not absorbed by the human bodies), but also forms the gel which is not sticky and oily when being smeared in a full-oil formula, has excellent skin feel, and can prepare a high sunscreen value product with SPF 30-50+ and PA value more than 8 according to the dosage of the sunscreen agent. Because the sunscreen gel is an anhydrous system, the sunscreen gel does not have the condition of oil-in-water or water-in-oil, and does not contain polyol, the sunscreen gel is not easy to wash away by water under the action of general shearing force, and has better water resistance.
