Definitions

• the invention relates to a synthetic soap comprising at least one binder.
• the object of the invention is to manufacture a syn­thetic soap by a simple production method starting from cheap raw materials, as a result of which the price of a piece of synthetic soap is comparable with that of an alkali soap; a second object is to manufacture a piece of synthetic soap whose properties equal or even exceed the traditional fatty acid alkali soaps in pro­perties. Important properties are, for example, the appearance, the smoothness of a piece of soap, and the foamformation.
• the binder consists of a mixture of one or more glycols, one or more alkali salts and one or more higher fatty acid derivatives containing from about 12 to about 22 carbon atoms, or in that the binder consists of a mixture of one or more glycols and one or more alkali soaps of one or more higher fatty acid derivatives containing from about 12 to about 22 carbon atoms.
• the use of the binder according to the invention for manufacturing a synthe­tic soap achieves the result that, by a simple method, a piece of synthetic soap can be manufactured whose cost price is low and which has remarkably good properties, such as a smooth appearance and ease of filling, while the binder according to the invention is miscible with the usual detergents and foamstabilizing agents and also with the usual fillers, dyestuffs and perfume composi­tions. After the constituents of the binder have been jointly melted, a product with a strongly film-forming action is produced.
• the synthetic soap according to the invention contains at least 10% by weight of one or more glycols such as monoethylene glycol, monopropylene glycol or butylene glycol or a polyglycol such as dipropylene glycol, di-, tri- or tetraethylene glycol or a mixture of two or more of the above-mentioned glycols, in the preferred compo­sition.
• glycols such as monoethylene glycol, monopropylene glycol or butylene glycol or a polyglycol such as dipropylene glycol, di-, tri- or tetraethylene glycol or a mixture of two or more of the above-mentioned glycols, in the preferred compo­sition.
• a quantity of water which exerts an action similar to hydrolysis on the binder according to the invention and has a stabilizing action may be added to a composition of the binder according to the invention.
• This property makes it possible to use the cheaper, aqueous detergents, such as, for example, Texapon N-40, which is a 28 per cent solution of sodium lauryl ether sulphate in water, and Texapon N-70, which is an approximately 70 per cent solution of said detergent.
• composition of a synthetic soap which falls within the scope of the invention is (in percen­tages by weight): ethylene glycol 35% sodium carbonate 10% stearic acid 17% water 27% sodium lauryl ether sulphate 11%.
• the condensation product of ethylene oxide and water in this composition has been chosen because of the low price of said glycol.
• the 27% water and the 11% sodium lauryl ether sulphate represent 38% of the composition, and the composition of said 38% corresponds to the com­position of the above-mentioned Texapon N-40.
• composition according to the invention which is particularly preferred owing to the production simplicity is as follows (in percentages by weight): propylene glycol 40% sodium stearate 19% Comperlan KD 3% Texapon N-40 38%
• Comperlan KD is coconut-alkyldiethanolamide and acts as a foam-stabilizing agent.
• Hardness-regulating substances for the binder can be added to the synthetic soap composition according to the invention, as shown in the following examples (in percentages by weight):
• Fillers such as potato flour, maize flour, chalk, precipitated calcium carbonate, bentonite etc. may be added to the synthetic soap according to the invention in the usual quantities.
• composition of a synthetic soap according to the invention which is perfumed and dyed is the follo­wing composition: ethylene glycol 400 parts sodium carbonate 150 parts stearic acid 150 parts alkane sulphonate 20 parts sodium lauryl sulphate 280 parts borax 5 parts titanium dioxide 5 parts perfume composition 15 parts
• composition of a synthetic soap according to the invention which when used produces copious and stable foam is as follows (in percentages by weight): butylene glycol (1,3-­butanediol) 35% sodium stearate 15% water 25% alkane sulphonate 93% 25%
• the method for preparing a synthetic soap according to the invention is as follows:
• the necessary quantity of glycol and sodium carbonate is heated to 80-100°C in a boiling kettle with a stir­ring mechanism.
• the necessary stearic acid is then added very gradually via a shaking sieve or a hopper and stir­red into the heated mixture.
• the supply of stearic acid should be adjusted to prevent excessive foam formation. Excessive foam formation may result in too much gas being left in the mixture.
• the other constituents, except the perfume compositions, are then stirred into the mixture. After the mixture has been cooled to approximately 60°C, the required perfume composition is added to the mixture. The mixture is then poured into the required moulds at a temperature of approximately 60°C or is further cooled and then extruded (rod-shaped pieces of soap).
• the consti­tuents of the mixture may be adjusted so that a mixture with the required properties is obtained at a particular temperature. Additional glycol produces a lower solidi­fication temperature. Additional water also brings about a reduction of the solidification temperature, while increasing the quantity of anhydrous detergents or sodium stearate increases the solidification temperature.
• the corresponding alkali soap sodium stearate
• soda sodium carbonate
• stearic acid soda (sodium carbonate) and stearic acid
• said sodium stearate is stirred into the heated glycol and melted down and then the other constituents, except the perfume composition, are added. Any perfume required is added only when the mixture has reached a temperature of 60°C, at which temperature the mixture can then be poured out into the required moulds.
• butylene glycol, di-, tri- and/or tetraethylene glycol are used as constituents of the mixture, it is advisable to have already mixed a proportion of the quantity of water to be added with the glycol beforehand before star­ting the mixing and melting down procedure.
