[0027] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application. In the following description, at least part of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

In the description of the present application, it should be noted that, unless otherwise specified, the meaning of "multiple" is more than two. Moreover, the term "include", "comprise" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only include those elements, but also include other elements not clearly listed, or also include elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the sentence "include..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0029] The moisturizing facial cream provided in the embodiment of the present application comprises an aqueous phase component, an oil phase component and an additive, wherein the aqueous phase component comprises water, a moisturizer, a thickener, a preservative and a chelating agent, and the oil phase component comprises an emulsifier, an emulsion stabilizer, an antioxidant and a moisturizer; the thickener comprises ammonium polyacryloyldimethyltaurate, carbomer and acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer; the emulsion stabilizer comprises a fatty alcohol; and the moisturizer comprises bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer linoleyl dimer linoleate and avocado butter.

[0030] In the embodiment of the present application, ammonium polyacryloyldimethyltaurate, carbomer and acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer are used as thickeners in the aqueous phase component, and these three components work synergistically to form a spatial framework structure; in the oil phase component, fatty alcohol is used as an emulsifier stabilizer, bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer linoleyl dimer linoleate and avocado tree butter are used as emollients, and three solid lipids with different hardness and melting points are filled in the three-dimensional framework formed by the thickener, which can promote the formation of cheese texture and make the cream have a silky skin feel and an effect of being easy to spread.

[0031] Specifically, ammonium polyacryloyldimethyl taurate has extremely low ion resistance, is not shear resistant, has short rheology, and can form a large cavity space after swelling, which can suspend and stabilize a part of the oil; carbomer has low ion resistance, extremely short rheology, but good suspension ability; acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer has medium ion resistance, short rheology, efficient thickening, and strong suspension ability. By using these three polymers with different ion resistance and overall medium to weak ion resistance in combination, the skin feel will be better, the water will break quickly, and the skin feel of the oil will be felt faster and more obviously; all three components have chosen short rheology and good suspension and stability, which is more conducive to the stability of the system and the uniform distribution of oil in the oil phase component. The system is based on the ammonium polyacryloyldimethyl taurate component, and carbomer and acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer assist in improving the system's ion resistance and system viscosity, and together play the role of suspending the oil in the oil phase component, breaking water quickly when applied, and the oil spreading obviously.

[0032] Among the oil phase components, fatty alcohol is a solid wax with a melting point of about 48℃-53℃; bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer linoleyl dimer linoleate is a solid wax with a melting point of about 38℃-40℃; avocado butter is a solid oil with a melting point of about 30℃. The melting point of avocado butter is lower than the skin temperature, and it has the effect of melting when touching the skin; the melting point of bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer linoleyl dimer linoleate is slightly higher than the body temperature, and it has a sense of drawing, picking, and adhesion, and is easy to adhere to and spread on the skin surface; fatty alcohol has a high melting point, and it can be used with emulsifiers to stabilize the emulsified oil components. Compared with wax components such as beeswax, it is more refreshing and smooth, and can reduce the heavy and sticky skin feel. The oil framework built by these three components in the alcohol component, combined with other liquid oils, can bring a cheese-like texture, a silky feeling of spreading and an effect of melting when touching the skin.

[0033] The synergistic effect of the space framework formed by the thickener in the water phase component and the lipid skin-melting space in the oil phase component gives the moisturizing cream a silky cheese texture with good skin feel and moisturizing effects.

[0034] In some embodiments, the mass ratio of ammonium polyacryloyldimethyltaurate, carbomer, and acrylic acid (esters) / C10-30 alkyl acrylate cross-linked polymer may be (2-4):1:(0.5-1).

[0035] In some embodiments, the mass ratio of ammonium polyacryloyldimethyltaurate, carbomer, and acrylic acid (esters) / C10-30 alkyl acrylate cross-linked polymer may be 3.5:1:0.8.

[0036] The mass ratio of ammonium polyacryloyldimethyltaurate, carbomer and acrylic acid (esters) / C10-30 alkyl acrylate crosslinked polymer is within the above range, which can make the formed framework structure have better ion resistance and suitable system viscosity, which is conducive to better suspension of the oil components in the oil phase component and achieve better suspension effect.

[0037] In some embodiments, the mass content of the thickener may be 0.4% to 0.8% based on the total mass of the moisturizing cream. For example, the mass content of the thickener may be 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, or a range consisting of any of the above values ​​based on the total mass of the moisturizing cream.

[0038] In some embodiments, based on the total mass of the moisturizing cream, the mass content of the thickener may be 0.53%.

[0039] When the mass content of the thickener in the moisturizing cream is within the above range, the product can be at an appropriate viscosity to form a frosty appearance, thereby helping the oil to be more stably suspended in the three-dimensional framework structure formed by the swelling of the thickener's polymer chains under hydration. At the same time, due to the compound use of thickeners with different thickening effects and ion resistance, it brings a comfortable and light touch, and the layers are rich and silky.

[0040] In some embodiments, the mass ratio of fatty alcohol, bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer dimer linoleate and avocado butter may be (1-3):5:(3-5).

[0041] In some embodiments, the mass ratio of fatty alcohol, bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer dimer linoleate and shea butter may be 1.8:5:3.5.

[0042] Fatty alcohols, bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer dimer dimer linoleate and avocado butter are combined in the above proportions to form an oil framework, which can form a better cheese-like texture, making the moisturizing cream have a silkier application feel and a melt-in-the-skin effect.

[0043] In some embodiments, the mass content of the emulsion stabilizer can be 1% to 3% based on the total mass of the moisturizing cream. For example, the mass content of the emulsion stabilizer can be 1%, 1.5%, 2.0%, 2.5%, 3.0%, or a range consisting of any of the above values ​​based on the total mass of the moisturizing cream.

[0044] When the content of the emulsifier stabilizer in the moisturizing cream is within the above range, the oil and emulsifier can be better dissolved together to help form a cheese-like texture; at the same time, it can increase the viscosity and hardness of the cream and enhance the product's melt-on-the-skin effect; in addition, when the content of the emulsifier stabilizer is within the above range, it is beneficial to form a moisturizing protective film on the skin surface during use, making the application feel more silky.

[0045] In some embodiments, the fatty alcohol may include one or more of stearyl alcohol, cetyl alcohol, and stearyl cetyl alcohol.

[0046] In some embodiments, the emollient may further include one or more of Limnanthes Alba seed oil, hydrogenated polyisobutene, and dimethicone.

[0047] In some embodiments, based on the total mass of the moisturizing cream, the mass content of the emollient can be 10% to 18%. Exemplarily, based on the total mass of the moisturizing cream, the mass content of the emollient can be 10.0%, 10.5%, 11.0%, 11.5%, 12.0%, 12.5%, 13.0%, 13.5%, 14.0%, 14.5%, 15.0%, 15.5%, 16.0%, 16.5%, 17.0%, 17.5%, 18.0%, or a range consisting of any of the above values.

[0048] The content of emollients in moisturizing cream is within the above range, which can form a hydrophobic moisturizing film on the skin surface, prevent the loss of water in keratinocytes, reduce external stimulation to the skin, and make the skin soft, smooth and shiny.

[0049] In some embodiments, the humectant may include one or more of glycerin, butylene glycol, 1,2-pentanediol, 1,2-hexanediol.

[0050] In some embodiments, based on the total mass of the moisturizing cream, the mass content of the moisturizing agent can be 8% to 15%. Exemplarily, based on the total mass of the moisturizing cream, the mass content of the moisturizing agent can be 8.0%, 8.5%, 9.0%, 9.5%, 10.0%, 10.5%, 11.0%, 11.5%, 12.0%, 12.5%, 13.0%, 13.5%, 14.0%, 14.5%, 15.0%, or a range consisting of any of the above values.

[0051] In some embodiments, the emulsifier may include one or more of a polyglycerol emulsifier, a glucoside emulsifier, and a sucrose ester emulsifier.

[0052] Illustratively, the emulsifier may include one or more of glyceryl stearate, PEG-20 stearate, PEG-40 stearate, PEG-100 stearate, or the like.

[0053] In some embodiments, the mass content of the emulsifier can be 1.5% to 3% based on the total mass of the moisturizing cream. For example, the mass content of the emulsifier can be 1.5%, 2.0%, 2.5%, 3.0%, or a range consisting of any of the above values ​​based on the total mass of the moisturizing cream.

[0054] In some embodiments, the additives include one or more of pH adjusters, skin conditioning agents, and other emollients.

[0055] In some embodiments, the mass content of the additive can be 1% to 3% based on the total mass of the moisturizing cream. For example, the mass content of the additive can be 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, or a range consisting of any of the above values ​​based on the total mass of the moisturizing cream.
