DE541235C - Process for the production of a liquid, non-gelatinizing soap - Google Patents

Description

By the patent 500,627 is a process for the production of liquid, non-gelatinizing Soaps have been protected by placing liquid soaps ammonium thiosulfate in a dryer In the form or in solution. However, the liquid soaps produced in this way have the disadvantage that they darken over time and sometimes tend to be reddish up assume reddish brown color.

It has now been shown that the prevention of gelatinization of liquid potassium soaps from sebum and palm oil or: sebum and palm oil-containing fats or their mixtures while avoiding the specified Reach deficiencies by adding potassium salts of acetic acid and lactic acid can. These salts can be the said soaps either in solid form or in solution can be added. But you can also z. B.

ao proceed in such a way that the soap contains an excess of alkaline potassium compounds and then add the required amount of acetic acid or lactic acid. The soaps produced in this way do not darken,

»5 but rather keep their water-clear color all the time Coloring.

The liquid soaps produced by this process are readily liquid without any further addition of glycerol, alcohol, sugar or potash up to -8 ⁰ C. They are clear in appearance and have excellent foaming power; They are also storage-stable, do not thicken over time and can be diluted to any desired fatty acid content without gelatinizing. Below a temperature of -3 ⁰ they become a little cloudy, but are still so fluid that they can easily pass through the openings of the soap dispensers. At +3 ⁰ C they become completely clear again, in contrast to other liquid soaps on the market, in which this clearing does not occur again ^{until around 13 0 C.} The liquid soaps produced by the process do not stick and have the advantage of being cheap over the liquid soaps that have been commercially available up to now.

For special purposes, the addition of potassium salts of acetic acid and Lactic acid produced soaps, of course, with other additives of various, against said salts of indifferent substances, such. B. glycerine, glycol, disinfectants, Manufacture perfumes, solvents and the like.

Examples

1. 8 kg of coconut oil, 2 kg of tallow and 1.3 kg of olein are ^{saponified warm with 7.2 kg of caustic alkali (40 0} Be) with the addition of 15 1 of water. Shortly after the saponification of the soap, 3.2 kg of a 5o ° / ₀ aqueous solution of potassium acetate was added. It is then allowed to cool and any impurities are nitrided.

2. 400 kg of coconut oil fatty acid, 100 kg of tallow fatty acid and 65 kg of olein are saponified while warm with 400 kg of potassium hydroxide solution (40 ⁰ Be) with the addition of 16001 of water. The soap thus produced is then reacted 157 kg of 5o ° / ₀ aqueous potassium

acetate solution and 155 kg to a 5o ° / ₀ solution of potassium lactate.

3. 60 kg of tallow fatty acid, castor fatty acid 10 kg, 10 kg and 15 kg olein hochsulfoniertes be turkey (45 ^»s%) saponified semi warm with 51 kg potassium hydroxide solution, 5.5 kg of a 5o ° / ₀ solution of potassium acetate, and as much water is added so that a 30 ° / _O occurs strength liquid soap.
