Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, in particular to a jelly air cushion and a preparation method thereof. Background Art

[0002] With the continuous development of the cosmetics industry and the increasing demand of beauty-loving ladies, air cushion products are increasingly sought after by people. At present, air cushion products mainly lock the inner material in the sponge powder core, but in this case, since the sponge has to be in a relatively moist state for a long time, it provides an additional growth environment for bacteria, making it easier for bacteria to breed. Secondly, in terms of usage time, since sponges are generally more likely to absorb powder, this will reduce the usage of the product. Finally, in terms of raw material usage, most of the current dosage forms are silicone oil-in-water types, and most of the emulsifiers and moisturizers used are also silicone oils. Excessive silicone oil content may cause pores to become clogged, resulting in the phenomenon of false skin slipperiness. Based on the above, it is currently necessary to develop an air cushion product that removes the sponge's moist and refreshing skin feeling, and does not contain silicone oil emulsifiers and moisturizers. Therefore, the design of the silk screen air cushion can meet the above shortcomings. Therefore, the technical problem to be solved by the present invention is to provide a moist, refreshing, low-irritation air cushion product without silicone oil emulsifiers and moisturizers. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a jelly air cushion and a preparation method thereof, which is an air cushion product with a Q-elastic appearance, a certain shape memory, and a moisturizing and refreshing skin feel.

[0022] Water 40-70%, Dibutyl Adipate 3-10%, Caprylic / Capric Triglyceride 2-8%, Propyl Heptyl Caprylate & Tocopherol 2-8%, 1,3-Propanediol 3-10%, Caprylic / Capric / Succinic Triglyceride 3-8%, Butyl Octyl Salicylate 1-8%, Niacinamide 1-3%, CI77891 & Coconut Oil-Caprylate / Caprate & Polyhydroxystearic Acid & Aluminum Hydroxide & Triethoxycaprylylsilane 4-12 parts, Pigment Colorant 0.5-1 part, Panthenol 0.5-2%, 1,2-Hexanediol 0.5-2%, 1,2-Pentanediol 0.5-2%, Sorbitan Sesquioleate 0.1-1%, Behenyl Alcohol 0.1-1%, Isononyl Isononanoate 0.1-1%, ammonium acryloyldimethyltaurate / VP copolymer 0.1-0.5%, sodium acrylate / sodium acryloyldimethyltaurate copolymer & water & polyisobutene & sorbitan oleate & capryl / decyl glucoside 0.1-1.0%, hydroxypropyl methylcellulose stearyl ether 0.05-0.3%, polyacrylate crosspolymer-60.05-0.5%, sodium stearoyl glutamate 0.02-0.4%, ethylhexylglycerin & tocopherol 0.03-0.1%, PEG-240 / HDI copolymer bis-decyltetradecyl polyether-20 ether & butylene glycol & water & potassium laurate & tocopherol (0.1-1.0% and adenosine 0.01-0.2%.

[0023] In the present invention, the dibutyl adipate and caprylic / capric triglyceride are light oils, emollients with moderate skin feel and moderate diffusion speed, and can provide the skin with a light, silky feeling of application and use.

[0024] In the present invention, the propyl heptyl octanoate is a skin moisturizer with a refreshing skin feel and fast diffusion.

[0025] In the present invention, the caprylic / capric / succinic triglyceride can provide the skin with a light and smooth feeling of application and use.

[0026] In the present invention, the butyl octanol salicylate is a dispersant and a wetting agent for ultrafine titanium dioxide, zinc oxide and a colorant, and also provides a certain moisturizing effect on the skin.

[0027] In the present invention, CI77492 / CI77491 / CI77499 is a pigment treated with triethoxycaprylylsilane and CI77891 has a certain degree of water resistance, and the specially treated powder can be more evenly dispersed in the oil phase, thereby reducing the possibility of the material forming a pigment band; at the same time, the product texture will be light and can be lightly applied to the skin surface, thereby improving the fineness of the product.

[0028] In the present invention, the isononyl isononanoate is a highly branched, low molecular weight, dry, filamentous ester, a low viscosity oily ester with a light, refreshing, silky feel, good color powder dispersibility, and a series of unique properties, including low freezing point, low viscosity, good penetration, excellent solubility, and good compatibility with other ingredients such as esters, volatile silicone oils, mineral oils, and vegetable oils.

[0029] In the present invention, the 1,2-hexanediol, 1,2-pentanediol and ethylhexylglycerol are preservatives with antibacterial effects, which not only have antibacterial effects but also have certain moisturizing effects.

[0030] In the present invention, the 1,3-propylene glycol is a moisturizer and solvent, and is an alcohol that is non-sticky, easily absorbable, has good spreadability, a soft skin feel, and a moisturizing effect after use.

[0031] In the present invention, panthenol is a gold standard moisturizer in the field of skin care, which can increase the hydration of keratin by inducing lasting skin moisturizing, and can also strengthen the skin barrier by reducing transepidermal water loss (TEWL). Secondly, it has a certain effect of soothing inflammation and improves the symptoms of sensitive skin to a certain extent.

[0032] In the present invention, the sorbitan sesquioleate is a nonionic surfactant and can be used as an auxiliary emulsifier and dispersant.

[0033] In the present invention, the behenyl alcohol is a straight-chain higher alcohol and is used as an emulsion stabilizer.

[0034] In the present invention, the sodium stearoyl glutamate is a highly efficient anionic emulsifier with excellent emulsifying properties and a very low usage amount, which enables formulators to adjust the skin feel of the product by improving the usage amount of oils, waxes and polymers, and can promote the formation of a lamellar liquid crystal phase with strong moisturizing ability; most powders such as titanium dioxide and iron oxide are negatively charged, and it is easier to prepare a stable emulsion using anionic surfactants.

[0035] In the present invention, the ammonium acryloyldimethyltaurate / VP copolymer has strong stability, thickening and emulsifying properties, and can be used in an emulsifying system without an emulsifier to reduce the irritation of the product, while making the product have a certain light feeling of use; when the hydrophobically modified copolymer is added to the O / W system, the structure of water will drive the hydrophobic part of the polymer into the O / W interface, and the hydrophilic part will remain in the water phase. The hydrophobic end group is firmly adsorbed on the interface like an "anchor". Because the hydrophobically modified polyelectrolyte can become an electrostatic steric stabilizer of the emulsion, the stability of the product is greatly improved.

[0036] In the present invention, the sodium acrylate / sodium acryloyldimethyl taurate copolymer, water, polyisobutylene, sorbitan oleate, and octyl / decyl glucoside have a refreshing feel and good fluidity, and can leave a refreshing but non-greasy feeling on the skin surface; at the same time, it can be operated at room temperature, without the need for neutralization, pre-dispersion or swelling, and the process flow is reduced.

[0037] In the present invention, the hydroxypropyl methylcellulose stearyloxy ether is a nonionic amphiphilic polymer, the structure of which is less affected by electrolytes, and can exhibit good salt resistance, and has good tolerance to acids, bases, salts, and other fillers in the oil phase. It is particularly suitable for products with a high salt content, can accommodate a higher proportion of the oil phase, and can have good stability even without adding a small molecule surfactant as an emulsifier.

[0038] In the present invention, the polyacrylate cross-linked polymer-6 is an electrolyte-resistant polymer with strong electrolyte resistance and stable suspension effect. It also has a moisturizing and velvety feel on the skin and can stabilize any type of oil phase at a low dosage.

[0039] In the present invention, the PEG-240 / HDI copolymer bis-decyltetradecyl alcohol polyether-20 ether & butylene glycol & water & potassium laurate & tocopherol is a thickener with strong salt resistance, shape memory and jelly elasticity, which can give the product a moisturizing skin feel and improve the product's fit.

[0040] The present invention provides a method for preparing the jelly air cushion described in the above technical solution, comprising the following steps:
