KR-20260064766-A - Method for producing solid cosmetic composition using hot melt extrusion method

Abstract

The present invention relates to a method for manufacturing a solid cosmetic composition using a hot melt extrusion method. More specifically, a solid cosmetic composition can be manufactured by hot melt extruding a mixture of two or more ingredients selected from the group consisting of antioxidants, thickeners, moisturizers, surfactants, pH adjusters, and preservatives, and then drying the obtained hot melt extruded product. The solid cosmetic composition of the present invention has enhanced resoluble properties so that it can be restored to the same form as a lotion, cream, gel, or liquid formulation cosmetic when water is added, and is easy to store and transport. Furthermore, it minimizes the use of plastic resulting from the use of existing liquid cosmetic compositions, and minimizes carbon emissions due to volume reduction during manufacturing and distribution processes.

Description

Method for producing solid cosmetic composition using hot melt extrusion method The present invention relates to a method for manufacturing a solid cosmetic composition using a hot melt extrusion method. Cosmetics used daily, such as hair care products like shampoos and conditioners, skin care products, and sunscreens in cream or liquid form, are manufactured and supplied to consumers in plastic containers or vinyl packs. However, as the number of consumers who place great value on eco-friendliness and sustainability increases, there is a growing demand for products that emphasize sustainability, ranging from ingredients and testing methods to containers and packaging. With the spread of the "Conscious Beauty" trend, a concept of ethical consumption enhanced by environmental awareness, an increasing number of customers are choosing to consume products produced using eco-friendly methods, extending beyond just the contents to the containers, packaging, and production processes. Furthermore, as the number of companies participating in zero-waste practices increases, efforts to reduce carbon emissions are continuing through processes such as using packaging materials that facilitate separation to decrease wastewater during the recycling washing process and saving energy by simplifying production processes. Solid cosmetics, which are being presented as an alternative amidst these trends and industry changes, fundamentally have the significant advantage of producing and consuming less plastic waste and severely limiting water usage within the product, thereby enabling a more active response to sustainability for protecting the global environment, such as reducing carbon emissions. However, currently used solid cosmetics are unable to replace liquid products. The primary reason for this is that, since products are made by simply mixing ingredients that maintain their solid or powder forms, they lack the diversity of raw materials compared to liquid cosmetics. For example, in the case of shampoo bars (solid shampoos), since the main ingredients are solid ingredients in powder form, conditioners cannot be used, and there are many limitations such as a stiff feeling compared to liquid shampoos. Therefore, in order to manufacture cosmetics that can replace existing liquid products while ensuring sustainability, it is urgently necessary to develop solid products that use liquid ingredients without modification, dissolve easily, and minimize volume. Meanwhile, hot-melt extrusion (HME) is widely used in various industries, including food, pharmaceuticals, and cosmetics. During the manufacturing process utilizing hot-melt extrusion, a mixture of active ingredients, thermoplastic polymers, and other additives is heated and softened within the extruder and discharged through a die in the form of granules or films. Additionally, it has the advantage of significantly reducing carbon emissions during production and delivery because the production process is simple, uses less water, and results in a small manufacturing volume. Therefore, the present invention provides a solid cosmetic composition that is easy to carry and has excellent usability, manufactured using an eco-friendly hot melt extrusion method. Regarding prior art related to solid cosmetic compositions, Korean Registered Patent No. 2639189 discloses a solid cleansing cosmetic composition with excellent skin application power, cleansing power, and skin improvement effects, and Korean Registered Patent No. 2114277 discloses a solid cosmetic composition and a method for manufacturing the same. However, there has not yet been any disclosure regarding the 'method for manufacturing a solid cosmetic composition using a hot-melt extrusion method' of the present invention.
