Description

Strong-cleaning bicontinuous phase composition and preparation method and application thereof
Technical Field
The invention relates to the field of IPC A61K8/00, in particular to a strong and clean bicontinuous phase composition and a preparation method and application thereof.
Background
With the improvement of life quality and health consciousness of people, various makeup removing products are introduced in the market, wherein the makeup removing water has fresh texture and poor cleaning effect; the cleansing oil has strong cleansing power, but has high skin irritation and is easy to damage the water-oil balance of the skin epidermis. Meanwhile, along with the optimization of the makeup in the aspect of improving the skin attaching force, the conventional makeup removing product cannot solve the problem that the makeup is deposited for the second time and removed thoroughly in the makeup removing process. Compared with the cleansing oil product, the bicontinuous phase composition has the effects of being fresh and not greasy in use and not needing to be cleaned by means of a cleansing product again after cleansing.
Chinese patent CN201710504241.3 discloses a cleansing emulsion gel and a preparation method thereof, and good cleansing effect is achieved through PEG-6 caprylic/capric triglyceride, polyalcohol compound, squalane and the like; the Chinese patent CN202010094991.X discloses a bicontinuous phase type eye and lip cleansing liquid and a preparation method thereof, wherein PEG-20 glycerol tristearate, sorbitol-30 tetraisostearate and an emollient are adopted to act, so that a cleansing product suitable for eyes and lips is obtained. The prior art still has the problem that cleansing power and safety mildness are not balanced, the skin irritation of the product capable of efficiently removing the makeup is often large, and the mild cleansing product cannot prevent the redeposition of the makeup. Under such a background, the research of a makeup removal product integrating makeup removal effect and safety and mildness is a problem to be solved in the art.
Disclosure of Invention
The invention solves the technical problem that the cleansing power and safety mildness cannot be balanced in the prior art by providing the bicontinuous phase composition with strong cleansing effect, and realizes the cleansing product with strong cleansing power, safety and stability by compounding the amphiphilic molecules in the bicontinuous phase system.
The invention provides a strong cleaning bicontinuous phase composition, which comprises the following raw materials in percentage by weight: 78-99.2% of surfactant composition and 0.8-22% of amphiphilic molecule;
in some preferred embodiments, the surfactant composition is divided into a first surfactant and a second surfactant; the weight ratio of the first surfactant to the second surfactant is (85-95): (1-4).
In some preferred embodiments, the first surfactant has an HLB value of 8 to 14 and the second surfactant has an HLB value of 20 or more.
Further preferably, the HLB value of the first surfactant is from 10 to 12 and the HLB value of the second surfactant is from 20 to 40.
In some preferred embodiments, the first surfactant comprises one or more of PEG-7 glycerol fatty acid ester, polysorbate, polyoxypropylene mannitol dioleate, PEG-8 dioleate, oleyl ether-5, polyoxyethylene lauryl ether, polyoxyethylene cetyl ether, PEG-20 sorbitan tristearate, polyoxyethylene oxypropylene oleate, PEG-40 castor oil, lauroyl sarcosine.

In some preferred embodiments, the amphipathic molecules comprise at least two of bis-diethoxydiglycol cyclohexane 1, 4-dicarboxylate, ethoxydiglycol, ethylhexyl glycerol, alkyl sulphates.
Further preferably, the amphipathic molecule is bis-diethoxydiglycol cyclohexane 1, 4-dicarboxylic acid ester and ethoxydiglycol, and the mass ratio of the bis-diethoxydiglycol cyclohexane 1, 4-dicarboxylic acid ester and the ethoxydiglycol is (5-10): (1-4); preferably 7:1.5.
When the conventional makeup removing product removes makeup, the problem that the cleaning force is insufficient and the makeup is removed incompletely often exists; the makeup removing oil can dissolve makeup faster and promote makeup removing force for makeup removing water and makeup removing cream. In the research process, the invention discovers that the cleansing power of the cleansing product can be obviously improved by adopting the first surfactant with the HLB value of 10-12 and the second surfactant with the HLB value of 20-40 to compound; the reason is probably that after the water-oil bicontinuous phase medium formed under the condition acts on the skin, the interfacial surface tension can be obviously reduced, so that the stagnation component in the makeup component is changed into a flowing component and separated from the skin along with the cleaning process, and the clean makeup removal effect is achieved.
However, with the improvement of people's consciousness of love, the staying effect of the color cosmetics on the skin surface is maintained and prolonged, and various auxiliary agents are often added into the color cosmetics to increase the adhesive capability of the color cosmetics on the skin surface; when makeup removal oil is used for makeup removal, secondary deposition of the auxiliary agents (such as pigments) is easy to occur in the dissolving process, and the auxiliary agents cannot be removed cleanly. According to the invention, a large number of experiments prove that the application of amphiphilic molecules, especially the combined action of macromolecular amphiphilic molecules (such as bis-diethoxydiglycol cyclohexane 1, 4-dicarboxylic acid ester) and micromolecular amphiphilic molecules (such as ethoxydiglycol or ethylhexyl glycerol) can obviously inhibit the secondary deposition adhesion of the makeup remover after the makeup remover is dissolved, the addition of specific amphiphilic molecules can improve the penetrability of the makeup remover composition at the interface between the makeup component and the skin surface layer, the makeup remover component after the amphiphilic molecules are added can be rapidly spread on the skin epidermis, and a layer of low-surface tension protective film is spread on the skin surface while the makeup component is dissolved, so that the re-enrichment and adhesion of the makeup remover on the skin surface are inhibited, and the effect of thoroughly removing the makeup is achieved.
In a second aspect, the present invention provides a method for preparing a strong clean bicontinuous phase composition, the method comprising the steps of: weighing the raw materials, mixing, heating to 30-50deg.C, maintaining the temperature, and stirring for 20-40min to obtain the product of the bicontinuous phase composition.
