Description

Technical Field

[0001] The invention relates to the field of skin care products, in particular to a moisturizing lotion spray and a preparation method thereof. Background Art

[0002] Skin care lotion is a cosmetic used to maintain the proper moisture in the skin. It not only maintains the balance of moisture in the skin, but also replenishes important oily components, hydrophilic moisturizing components and moisture. It can also serve as a carrier of active ingredients so that the active ingredients can be absorbed by the skin, thereby achieving the purpose of conditioning and nourishing the skin.

[0003] Spray is a mixture of tiny particles suspended in a gas (such as air). Generally, liquid is sprayed out in the form of extremely fine water particles through a high-pressure system. These tiny artificial atomized water particles can drift and suspend in the air for a long time, forming a delicate white mist. When the spray contacts the skin, it can be evenly dispersed on the skin, which is convenient, simple and comfortable to use.

[0004] When using traditional lotions, it is easy to have uneven application on the face. In addition, due to the difficulty of atomizing traditional lotions, they are usually only ejected in the form of water columns when pressurized, and cannot form a delicate spray form, so they cannot be sprayed evenly on the skin surface. The viscosity of ordinary sprays is low, and they can usually only be made into simple water solutions, and cannot be made into a stable emulsified system. Therefore, their moisturizing effect is insufficient, especially in autumn and winter, which is not enough to provide a good moisturizing effect for the skin. Summary of the invention

[0005] In order to combine the advantages of both, provide a moisturizing lotion that can be used in a spray manner, and solve the problems of the stability of the lotion and the atomization effect of the lotion at the same time, the present application provides a moisturizing lotion spray and a preparation method thereof.

[0006] In the first aspect, the present application provides a moisturizing lotion spray, which adopts the following technical solution:

[0007] A moisturizing body lotion spray comprises ammonium acryloyldimethyltaurate / beheneth-25 methacrylate cross-linked polymer, an emulsifier, a moisturizer, oil, a skin conditioner, other adjuvants and water, wherein the mass percentage of the ammonium acryloyldimethyltaurate / beheneth-25 methacrylate cross-linked polymer is 0.2-0.5%, the mass percentage of the emulsifier is 0.5-2%, and the emulsifier is a combination of an auxiliary emulsifier and tri(ceteareth-4) phosphate.

[0008] At present, there are few reports on the research of moisturizer spray that can be used in a spray form. This is because it is very difficult for moisturizer spray to form a good spray effect, and when making moisturizer spray, there is also the problem of poor stability of the moisturizer system and easy stratification, which makes it difficult to pass the stability test experiment.

[0009] The applicant has found that the key to achieving both better spray effect and emulsification stability for the lotion spray is the combination of the thickening system and the emulsification system. The present application uses ammonium acryloyldimethyltaurate / behenyl alcohol polyether-25 methacrylate cross-linked polymer as a thickener, and is matched with tri(ceteareth-4) phosphate and a co-emulsifier as an emulsification system. The resulting lotion spray has both good spray effect and stability. After the lotion spray is pressurized and sprayed out, it can not only produce a delicate spray, giving people a good spray experience, but also the lotion spray has excellent stability, overcoming the disadvantage of poor stability of the emulsification system that is very easy to occur in the process of making the lotion spray. After storage experiments, cold and heat stability tests and centrifugation tests, it maintains better stability and is not easy to stratify.

[0010] Preferably, the mass ratio of the ammonium acryloyldimethyltaurate / beheneth-25 methacrylate crosspolymer to tri(ceteareth-4) phosphate is 0.3:(0.8-1).

[0011] When ammonium acryloyldimethyltaurate / beheneth-25 methacrylate crosspolymer and tri(ceteareth-4) phosphate are combined in a mass ratio of 0.3:(0.8-1), it is beneficial for the emollient spray to form a fine mist when it is sprayed, and at the same time improves the stability of the emollient spray system.

[0012] Preferably, the co-emulsifier is bis-PEG / PPG-16 / 16PEG / PPG-16 / 16 polydimethylsiloxane or glyceryl stearate citrate.

[0013] The addition of bis-PEG / PPG-16 / 16PEG / PPG-16 / 16 polydimethylsiloxane or glyceryl stearate citrate can increase the stability of the lotion spray, among which bis-PEG / PPG-16 / 16PEG / PPG-16 / 16 polydimethylsiloxane has the best effect.

[0014] Preferably, the mass percentage of the moisturizer is 6.38-15.3%, the mass percentage of the oil is 2-8%, the mass percentage of the skin conditioner is 0.25-0.8%, the mass percentage of other auxiliary agents is 0-1.66%, and the total amount of solvent added to the lotion spray is 100%.

[0015] Preferably, the oil is one or a combination of squalane, ethylhexyl palmitate and dimethicone.

[0016] Preferably, the mass percentages of the various components in the oil are as follows:

[0017] Squalane 0.5-2%

[0018] Dimethicone 0.5-2%.

[0019] Ethylhexyl palmitate 1-4%

[0020] One or more combinations of squalane, ethylhexyl palmitate and dimethicone can produce a good emulsification effect in the emulsification system of the present application, thereby moisturizing the skin and providing a good moisturizing effect for the skin surface. The emulsification effect and moisturizing effect produced by the combination of squalane, ethylhexyl palmitate and dimethicone in the above specific ratios are the best.

[0021] Preferably, the moisturizing agent is a compound of one or more of glycerin, dipropylene glycol, isobutylene glycol and water-locking magnet.

[0022] Preferably, the mass percentages of the various components in the moisturizing agent are as follows:

[0023] Glycerin 1-5%

[0024] Dipropylene glycol 1-5%

[0025] Isobutylene glycol 1-5%

[0026] Water-locking magnet 0.08-0.3%.

[0027] One or more of the above-mentioned glycerin, dipropylene glycol, isobutylene glycol and water-locking magnet, as moisturizers for lotion spray, can quickly improve the skin's dehydrated state and provide excellent moisturizing effect for the skin.

[0028] Preferably, the skin conditioning agent is one of 0.2-0.5% by mass of silicon powder and 0.3% by mass of AQP Free NP Linlan Runlu, or a combination of the two.

[0029] Preferably, the other auxiliary agents are one or a combination of preservatives and fragrances.

[0030] Preferably, among the other auxiliary agents, the mass percentage of the preservative is 0.5-2%, and the mass percentage of the fragrance is 0.02-0.06%.

[0031] In a second aspect, the present application provides a method for preparing an emollient spray, using the following technical solution:

[0032] A method for preparing a moisturizer spray comprises the following steps: pre-dissolving water, a thickener and a part of a moisturizer, and mixing them evenly to obtain a phase A; pre-dissolving oil, an emulsifier and a part of a skin conditioner, and mixing them evenly to obtain a phase B; mixing the phase A and the phase B, homogenizing them evenly, and then adding the remaining raw materials, mixing them evenly to obtain the moisturizer spray.

[0033] In summary, this application has the following beneficial effects:

[0034] 1. This application increases the softness and moisturizing feeling of the lotion on the basis of spraying, enhances its moisturizing ability, overcomes the problem of easy stratification of low-viscosity lotions during high and low temperature tests, and ensures its atomization effect.

[0035] 2. The present application uses ammonium acryloyldimethyltaurate / beheneth-25 methacrylate crosspolymer as a thickener, and is matched with tri(ceteareth-4) phosphate and a co-emulsifier as an emulsifying system. The resulting lotion spray has both good spray effect and stability, and uses bis-PEG / PPG-16 / 16PEG / PPG-16 / 16 polydimethylsiloxane or glyceryl stearate citrate as a co-emulsifier, both of which can increase the stability of the lotion spray.

[0036] 3. Ordinary low-viscosity aqueous sprays are mist when sprayed far or near, but the lotion spray in this patent application is mist when sprayed far away and emulsion when sprayed near. It can be used as a spray and also as a lotion, killing two birds with one stone. BRIEF DESCRIPTION OF THE DRAWINGS
