... The process of formulating water-based body wash cosmetics with a high content of hydrophobic substances creates both technological and physicochemical difficulties. The most common problems are related to system instability, the need to use surfactants at high concentrations, very high viscosity of formulations, and relatively long time of reconstitution in water [24]. Solid cosmetics (in cube, powder and tablet forms) provide the possibility of using relatively large quantities of hydrophobic substances in their formulation. ...
The aim of the study was to evaluate the effects of hydrophilic microcrystalline cellulose, hydrophobic talc and mixtures of cellulose and talc when used as fillers in powdered bath cosmetics. A number of model formulations were developed that contained fillers in different compositions. Prototypical formulations were prepared and evaluated for their functional properties and skin-drying effect. An increase in the concentration of talc was found to reduce the ability of the formulations to emulsify fatty soils and, consequently, decrease the skin-drying effect after washing. Another result of the study is that a high content of talc does not significantly impair the foaming ability, and the presence of talc improves the stability of generated foam.
This study sought to evaluate the possibility of using grape pomace, a waste material from wine production, for the preparation of cosmetic components. Following the existing clear research trend related to improving the safety of cleansing cosmetics, an attempt was made to determine the possibility of preparing model shower gels based on grape pomace extract. A new method for producing cosmetic components named loan chemical extraction (LCE) was developed and is described for the first time in this paper. In the LCE method, an extraction medium consisting only of the components from the final product was used. Thus, there were no additional substances in the cosmetics developed, and the formulation was significantly enriched with compounds isolated from grape pomace. Samples of the model shower gels produced were evaluated in terms of their basic parameters related to functionality (e.g., foaming properties, rheological characteristics, color) and their effect on the skin. The results obtained showed that the extracts based on waste grape pomace contained a number of valuable cosmetic compounds (e.g., organic acids, phenolic compounds, amino acids and sugars), and the model products basis on them provided colorful and safe natural cosmetics.
The aim of this article is to define the role of environmental management in the processes of research and development conducted by the partners in the supply chain. The publication describes the emerging trends related to the requirements of international companies (especially Original Equipment Manufacturers - OEMs) on reducing suppliers’ negative impact of new products on the environment. Increasingly, these requirements are taken into account during the initial assessment and periodic suppliers. The expectations that international companies have of suppliers include an ever wider range of implementations of the concept of environmental management contained in the ISO 14000 series of International Standards. These expectations include: the implementation of an environmental management system (in accordance with the guidelines of ISO 14001), the implementation of LCA (ISO series 14040), and the use of environmental labels and environmental statements (as required by series 14040). OEM companies are not limited to placing stringent requirements on suppliers. Many multinationals offer their suppliers special programs to support the implementation of environmental management.
