Definitions

• Shaped soap product containing talc, one or more fatty acids in the form of their Alkaline soaps and one or more non-ionic surfactants in the absence of Alkyl (oligo) glycosides.
• the present invention relates to cosmetic cleaning agents in the form of shaped soap products. Such means are known per se. It is essentially about surface-active substances or mixtures of substances that the consumer in different Preparations are offered.
• the invention particularly relates to bar soaps with improved Smoothness and increased lime soap dispersing capacity due to the content of talc and one or more nonionic surfactants in the absence of alkyl (oligo) glycosides.
• Surfactants best known are the alkali salts of higher fatty acids, i.e. the classic "soaps" - are amphiphilic substances, the organic non-polar substances in water can emulsify.
• a simple water bath without the addition of surfactants is the first step swelling of the horny layer of the skin, the degree of this swelling being, for example, from depends on the duration of the bath and its temperature. At the same time, they become water-soluble Fabrics, e.g. water-soluble dirt components, but also the skin's own substances that Water binding capacity of the horny layer are responsible, washed off or washed out.
• water-soluble Fabrics e.g. water-soluble dirt components
• the syndet soap, so-called “Syndetbars” which are free of fatty acid salts except for impurities and contain only synthetic surfactants.
• the main components are the alkali salts of the fatty acids of natural oils and the like. Fat, preferably of chain lengths C 12 -C 18 . Since lauric acid soaps foam particularly well, the lauric acid-rich coconut and palm kernel oils are preferred raw materials for fine soap production.
• the sodium salts of the fatty acid mixtures are solid, the potassium salts are soft-pasty. For saponification, the dilute sodium or potassium hydroxide solution is added to the fat raw materials in a stoichiometric ratio in such a way that the finished soap contains a maximum of 0.05% alkali. In many cases, soaps are no longer made directly from fats, but rather from the fatty acids obtained by fat splitting.
• Common soap additives are fatty acids, fatty alcohols, lanolin, lecithin, vegetable oils, partial glycerides and other fat-like substances for regreasing the cleansed skin, antioxidants such as ascorbyl palmitate or tocopherol to prevent the autoxidation of the Soap (rancidity), complexing agents such as nitrilotriacetate to bind traces of heavy metals, which could catalyze autoxidative spoilage, perfume oils to achieve the desired fragrance notes, dyes for coloring the soap bars and if desired special additives.
• Surfactants are amphiphilic substances that can dissolve organic, non-polar substances in water. Due to their specific molecular structure, they provide at least one hydrophilic and a hydrophobic part of the molecule, for a reduction of the surface tension of water, wetting the skin, facilitating dirt removal and solution, easy rinsing and - if desired - for foam regulation.
• Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution they form negatively charged organic ions in an acidic or neutral environment. Cationic surfactants are characterized almost exclusively by the presence of a quaternary ammonium group. In aqueous solution they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and accordingly behave like anionic or cationic surfactants in aqueous solution depending on the pH. They have a positive charge in a strongly acidic environment and a negative charge in an alkaline environment.
