Description

Cosmetic composition for body cream with excellent moisturizing and exfoliating effects and method for making the same The present invention relates to a cosmetic composition for body cream comprising wild pear extract and brewer's yeast extract, and a method for manufacturing the same. By including various types of natural extracts, the invention provides a cosmetic composition for body cream that improves moisturizing power and spreadability of the body cream product and simultaneously provides an exfoliating effect, as well as a method for manufacturing the same. The skin of modern people is easily damaged or dried out by external factors such as environmental pollution, UV exposure, and dry air; consequently, skin moisturization and exfoliation have emerged as critical challenges in cosmetic development. Moisturizing power is a key element for maintaining skin health, essential for retaining moisture on the skin surface and strengthening the skin barrier to protect the skin from external stimuli. At the same time, exfoliation plays a vital role in smoothing skin texture and enhancing the absorption of cosmetics by removing unnecessary dead skin cells. Currently, various cosmetics aimed at moisturizing and exfoliating are being released on the market, but many products rely on chemical ingredients. While these chemicals are used to enhance moisturizing effects, they can impair spreadability and user experience, and there is a possibility that they may cause skin problems with long-term use. Consequently, consumers with sensitive skin are increasingly preferring mild cosmetics based on natural extracts rather than chemical ingredients, leading to a growing demand for products that can meet these needs. In particular, since products like body cream are applied broadly across the entire body unlike facial skin, they are required to provide not only moisturizing benefits but also functional effects such as exfoliation. For instance, many consumers experience discomfort due to dead skin cells forming on various parts of their skin caused by dry summer weather or air conditioning. Under these circumstances, there is a continuously increasing demand for functional body creams that maintain skin hydration for a long time while gently removing dead skin cells. FIG. 1 is a schematic diagram of a method for manufacturing a cosmetic composition for body cream according to the present invention. Terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Therefore, the configuration of the embodiments described in this specification is merely one of the most preferred embodiments of the present invention and does not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application. In this specification, singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, when a part is described as "comprising" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Thus, for example, a composition comprising compound A may include compounds other than A. However, the term "comprising" also encompasses, in a more restrictive sense as a specific embodiment thereof, "essentially/essentially composed of" and "composed of," so that, for example, a "composition comprising compound A" may also be (essentially/essentially) composed of compound A. In this specification, when any member is described as being located "on" another arbitrary member, this includes not only cases where such member is in contact with another member, but also cases where another member or material exists between the two members. Where in this specification a quantity, concentration, or other value or parameter is given as an enumeration of a range, a preferred range, a preferred upper limit, and a preferred lower limit, it should be understood that any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether the range is disclosed separately, specifically discloses any range that may be formed. Where a range of numerical values is mentioned in this specification, unless otherwise stated, for example, without limiting terms such as greater than or less than, the range is intended to include its endpoint value and all integers and fractions within that range. The scope of the invention is not intended to be limited to the specific value mentioned when defining the range. Among the physical properties mentio
