Description

Cleansing cosmetic composition comprising sodium polyacrylate The present invention relates to a cleansing cosmetic composition comprising sodium polyacrylate, and specifically, to a cleansing cosmetic composition that forms a specific formulation through a combination of sodium polyacrylate and a specific surfactant. Conventional cleansing cosmetic compositions contain various surfactants and auxiliary ingredients to ensure cleansing efficacy, but there were several limitations in terms of formulation properties. For example, problems arose where the contents flowed or separated easily, which reduced stability during long-term storage. In addition, if the extensibility of the formulation was insufficient, it could not be applied uniformly to the skin surface during cleansing, resulting in reduced cleansing efficacy. Conversely, when viscosity or hardness was excessively high, there were disadvantages such as difficulty in dispensing from tube containers or user discomfort. Therefore, conventional cleansing compositions found it difficult to simultaneously satisfy cleansing efficacy, formulation stability, and ease of use, and also faced limitations in ensuring packaging suitability. Accordingly, the inventors of the present invention closely analyzed the physical properties of the formulation and conducted repeated research on ingredient combinations and blending conditions that can simultaneously improve extensibility and viscoelasticity, and completed a cleansing cosmetic composition capable of achieving a firm and high-density texture while having excellent formulation stability. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by a skilled expert in the art to which the present invention pertains. In general, the nomenclature used herein is well known and commonly used in the art. Furthermore, in describing embodiments of the present invention, detailed descriptions of related known configurations or functions are omitted if it is determined that such detailed descriptions would hinder understanding of the embodiments of the present invention. Additionally, while embodiments of the present invention will be described below, the technical concept of the present invention is not limited or restricted thereto and can be modified and implemented in various ways by those skilled in the art. In this specification, when a part is described as including a certain component, it means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. In this specification, the term "and/or" includes a combination of a plurality of related items or any one of a plurality of related items. According to an embodiment of the present invention, a cleansing cosmetic composition comprising sodium polyacrylate, cellulose, citric acid, and a surfactant is provided. The cosmetic composition of the present invention is characterized by achieving a unique formulation while having excellent cleansing efficacy and formulation stability through the combination of the above ingredients. In the present invention, “sodium polyacrylate” is a polymer electrolyte component obtained by polymerizing the sodium salt of acrylic acid, exists in powder form at room temperature, and can have the characteristic of absorbing moisture to form a gel. In the present invention, sodium polyacrylate can play a role in retaining moisture and controlling viscosity, and can contribute to realizing the specific formulation of the present invention by improving the viscoelasticity of the formulation and imparting extensibility. The sodium polyacrylate may be included in an amount of 0.05 to 1 weight% based on the total weight of the cosmetic composition according to the present invention, specifically 0.05 to 0.9 weight%, and more specifically 0.3 to 0.5 weight%, but is not limited thereto. When the sodium polyacrylate is included in the above amount, a unique formulation with excellent extensibility and viscoelasticity, including an elongating appearance, high density, and high viscoelasticity, can be realized, and excellent cleansing efficacy and formulation stability can be realized. On the other hand, if the sodium polyacrylate is included in a small amount less than the above amount, a problem may arise in which the extensibility and viscoelasticity of the formulation are reduced, and if the sodium polyacrylate is included in an excessive amount more than the above amount, a precipitation phenomenon may occur, resulting in poor formulation stability. In the present invention, “cellulose” is a natural polysaccharide that constitutes plant cell walls and can generally be used as a thickening agent or stabilizer in cosmetic compositions. In the present invention, it is included in powder form to strengthen the structure of the formulation and form a viscoelastic network to help the contents maintain extensibility without flowing e
