Soap and Cleaning - Free recipes for homemade soaps

For the cleaning of all objects with which we come into contact in daily life, an enormous number of preparations are marketed, some of them under very fancy names, but all of which contain soap, alkalis or solvents. In most cases, soap in one form or another is the main ingredient, in a few cases it is the newly discovered salts, which have very serious properties. Solvents are rarely used for domestic purposes, almost exclusively as stain removers.

Liquid soap

One can start from a mixture of one third part coconut fat and two thirds soybean oil.
For example, one saponifies:
Soybean oil 10.75 dl
Coconut fat 5 dl
Caustic soda of 50° Bé 7.87 dl
The soap formed is dissolved in 77 dl of water, to which 0.5 dl of potash has been added.
Another soap can be made from:
Coconut fat 10.75 dl
Castor oil 5 dl
Caustic soda of 50° Bé 7.48 dl
The soap is dissolved in 76 dl of water to which 0.5 dl of potash has been added.
Coconut fat 8.5 dl
Oleic acid 5 dl
Caustic soda of 50° Bé 7.3 dl
After saponification, the soap is dissolved in 77 dl of water and 0.5 dl of potash.

With this type of saponification it can be seen that, after mixing the different components, the temperature rises only very slowly.

At the low temperature, saponification proceeds very slowly, so little heat is released. As the temperature rises, the saponification process goes faster and more heat is released. It can then be seen that when the temperature of about 65℃ is reached, the temperature rises very quickly to about 85℃. At this temperature, most of the fat is now saponified and the amount of heat that is released will decrease again from now on, as there is not so much unsaponified fat left. The temperature now rises slowly to 94 to 96℃, after which the boiler contents begin to cool down. At this point only traces of unsaponified fat may be present. If there is still too much free fat in the soap, it must be saponified by vigorous stirring.

In the beginning the mass in the cauldron is very thick, then becomes more thin and with further saponification the mass becomes thick again. At this point the agitator is stopped for several minutes and the soap is examined for free fat and free lye. The soap should have a sharp acrid taste at this point on the tongue. Of course, the research can be carried out precisely in the laboratory. A small amount of soap is dissolved in water.

The solution must be completely clear; a cloudy solution indicates unsaponified fat. If you have used too little lye, you will not find any more lye in this case and you will have to add the missing lye as 30° Bé lye. The saponification is then terminated by stirring. This can occur when the caustic potash has absorbed carbon dioxide from the air due to standing too long and therefore consists partly of potash, potassium carbonate.

Finally, the soap should contain a small excess of lye.

If the excess lye is too large, the excess must be neutralized. To this end, the calculated amount of coconut fat or, better still, oleic acid is added to the soap. After about 15 minutes of stirring, one takes another test and sees whether the soap is now good.

A soap cooked in this way contains about 65% fatty acid. By diluting with three times the amount of soft water, a liquid soap with about 16% fatty acid is obtained. With a well-cooked soil soap, this liquid soap is then practically neutral. Since even the smallest amount of unsaponified fat in a liquid soap is very unpleasant, one often saponifies with an excess of lye, dilutes the soap and now neutralizes the too strongly alkaline liquid soap with sour Turkish red oil. With this, the neutralization is instantaneous and complete.

A liquid soap with less fatty acid can be made by diluting the soap with sugar solution.

natural soap with lavender

For example, one saponifies:

Palm oil 80 dl
Sunflower oil 50 dl
Caustic soda of 50° Bé 52 dl
The soap is neutralized and mixed with a solution of:
Sugar 200 dl
Potash 10 dl
Potassium chloride 10 dl
Water 1000 dl

Liquid shampoos

Colophonium WW 1.2 dl
Coconut fat 2.5 dl
Glycerin 16.2 dl
Olive oil 13.0 dl
Caustic soda of 38° Bé 9.6 dl
Water 57.5 dl
Wright's Coal Tar Soap when it still contained real coal tar

Tar soap

A tar soap is obtained by adding a tar solution to the liquid soap. The solution consists of:
Wood tar 250 dl
Sodium bicarbonate 15 dl
Water 1000 dl
The mixture is allowed to stand in a warm place for several days and then filtered. The soap is colored brown with a water-soluble brown aniline dye.
The manufacture of these shampoos, for which many other fat combinations can of course be used, is best done in an enamelled kettle that is double-walled and can be heated with steam from several atmospheres. The fats are first melted and heated to 70-80℃ and then saponified with the caustic soda of 38gr Bé. After complete saponification, the free caustic content is adjusted to 0.05 to 0.15% Na2O.

After this, the soap is diluted with condensed water or distilled water, the glycerin is added and allowed to cool.

Finally, the perfume and possibly medicines are added and the soap is placed in high reservoirs in which the contaminants can settle. The clear soap solution is then drained off after some time. The soap should be clarified at the lowest possible temperature to prevent the soap from becoming cloudy later in cold weather. In general, diluting with ½ to 1 percent potash solution produces soaps which clear easily.

Whereas in the past people had to rely on dyes supplied by the plant and animal kingdoms for coloring soaps, emulsions and similar products, today artificial dyes are made too expensive and too expensive. These have the advantage of always being delivered completely evenly, so that you always know exactly how much to add to get a certain shade.

The coloring of soap has of course no influence at all on the quality. However, such items are much easier to sell when they have an eye-pleasing appearance. Soaps intended for industry are usually left uncoloured.

Today, chlorophyll is still used here and there for greenery, which is commercially available in three types, namely soluble in water, in spirit and in oil.
However, chlorophyll is very poor in lightfastness and the dye is much too expensive in relation to the aniline dyes that can replace it. Natural dyes are also used in some cases for red and yellow, for example: carmine, kermes, curcuma and alkannine.

For some types of soap, pigment is still used for coloring, i.e. insoluble dye. Of course, these must not discolour even under the influence of alkali. They are ultramarine blue, vermilion and iron oxide red.

The solid, almost anhydrous soaps can be colored with dyes that are soluble in water or in oil, the liquid soaps are always colored with water-soluble dyes. The amount needed is usually very small. It should not be forgotten that the dye in the soap is simply dissolved and is not chemically bonded as is the case with the dyeing of fabrics. Soap with too much dye will come off.

The following dyes are used: rhodanine, cyanine green, metanil yellow, alizarin blue, Bismarck metanil yellow, alizarin blue, Bismarck brown, fluorescein, violamine, acid violet, etc. Now the colors are slightly different depending on the factory that makes the dyes. In general, the dye is ordered stating the desired shade and exactly the purpose for which the dye is to be used. This alone makes it possible to always get the right kind. The dye manufacturers know exactly for what purposes a certain type of dye is suitable.

Liquid hand washing soap

Soaps are made for washing very dirty hands, to which solvents for grease are added. These types of soaps are very popular in garages and factories, for example. Those with pine oil are also disinfectant. Usually one starts with a pure coconut soap, sometimes mixed with another vegetable oil soap, and diluted with as much water as corresponds to the price. When liquid soap is strongly diluted with water, spirit, sugar or glycerin must be added to lower the freezing point, otherwise the soap cannot be transported in winter. Moreover, with these additions, the soap remains better in solution and the soap therefore remains clear.

Pine oil soap

Coconut fat 160 dl
Potassium hydroxide (89%) 46 dl
Pine Oil 40 dl
Water 754 dl
The coconut fat is heated to 80-85℃. The potassium hydroxide is dissolved in enough water to obtain a 20 percent potassium hydroxide solution. Half of the lye is now added to the heated fat while stirring. kept at 80 to 85℃ for up to 3 hours with good stirring.
The solution is finally well cooled and filtered cold. After this, the pine oil is slowly mixed with the soap solution while stirring.

Liquid household soap with pine oil

Oleic acid (acid number 194) 61.6 dl
Colophony (acid number 165) 61.6 dl
Sodium hydroxide 85% 18.7 dl
Pine Oil 133.0 dl
Trisodium phosphate 26.7 dl
Water 700.8 dl
The oleic acid and the rosin are melted together and heated to 80℃. The sodium hydroxide is dissolved in enough water to make a 20 percent sodium hydroxide solution and half of the lye is added to the fatty acid resin mixture. The rest of the water, in which the trisodium phosphate has been dissolved, is added to the soap emulsion, all while stirring well. The temperature is now lowered to 60℃ and the rest of the lye is added while stirring vigorously. Stirring is continued for 15 minutes. After everything is completely saponified, the pine oil is added and stirred well for a few more minutes.

This liquid soap is relatively dark in color, depending on the quality of the fatty acid and the resin, however, it is extremely suitable for cleaning linoleum, rubber floors, terrazzo and painted floors.

The soap removes greasy residues very easily, removes unpleasant odors and does not affect paint and other materials. The soap is very cheap to manufacture and is also cheap to use. About 100 to 150 g are mixed in a bucket of hot water.

Soap powder with pine oil

Oleic acid (acid number 195) 50 dl
Colophonium (s.get. 165) 50 dl
Sodium hydroxide (100 pc) 13.3 dl
Pine Oil 100 dl
Soda (58 pc) 737 dl
Water 4.7 dl
The oleic acid and rosin are melted together and heated to 80℃. The sodium hydroxide is dissolved in the water. At 60℃ the acid mixture is now saponified with the lye. After adding the entire amount of lye, stir gently until everything is saponified. After this, the soap is dissolved in the pine-oil by adding the pine-oil to the soap and then mixing the soda with the soap in a mixing device.

This soap powder is extremely suitable for cleaning dirty greasy floors, as is often the case in garages and factories. Concrete floors in particular become very clean with this. In addition, the smell of the pine oil, which lingers, is not unpleasant. Less pleasant smells are covered by the scent of the pine oil. Moreover, this soap powder does not make the floor slippery.

The powder can be sprinkled on the floor. After this, it is wetted with a watering can or a water hose and then scrubbed with a broom or the powder is dissolved in warm water.

Household soap

Manila Coconut Fat 50 dl
Stearic acid 450 dl
Sodium hydroxide solid 75 dl
The fats are melted and the solid caustic is dissolved in water to a solution with an s.g. of 1.116 is obtained. The lye is now slowly added to the melted fat and the whole mass is brought to a boil. As the lye is absorbed by the fat, the lye is gradually added until all the fat has been saponified. The soap is then salted out with solid table salt, boiled again and pressed into pieces. If the soap is too hard, use a little more coconut fat. After all, the soap contains about 30% water.

Cresol soap

A mixture of equal parts soft soap and tar oil cresol is heated on a water bath, stirring well, until the mass is completely homogeneous. For making large quantities it is more economical to make the soap and add a small amount of cresol during saponification. This keeps the soap liquid. Then the rest of the cresol is added. It is not even necessary to saponify the oil completely, as the saponification ends automatically when standing.

By replacing part of the cresol with chlorine compounds of the phenols, e.g. by parachlorophenol or bromo-o-cresol, disinfects the soap considerably better and in larger dilutions.

Formaldehyde soap

Coconut fat 30 dl
Caustic potash 8 dl
Water 20 dl

The fats are melted and heated to 65°C. Then the lye, which was previously heated to 35[deg.] C., is added. The resulting emulsion is now allowed to stand for about 2 hours, care being taken to keep the mass warm. The triaethanolamine is then added, a sample of the soap is dissolved in alcohol and phenolphthalein is added. The soap should be weakly alkaline. If it still contains too much lye, a little stearic acid is added. After this, the soap is neutralized with the cimol or made slightly acidic. Shortly before pouring the soap into molds, the lanolin and thiosulphate solution are added and stirred well. Finally, the soap is dried.
The soap is further improved by adding 3% of the following mixture:

Shaving soap can also be improved by adding 50 g of menthol to 100 kg of soap, which has been previously dissolved in 100 g of alcohol. has to add. The menthol gives a cooling sensation and removes the tingling of the soap.


Hard potash soap for the textile industry

Coconut oil fatty acid 30 dl
Groundnut oil fatty acid 20 dl
Tallow fatty acid 50 dl
Potassium solid approx. 20 dl
Water approx. 40 dl
The correct amount of lye must be calculated by determining the saponification number of the fatty acid mixture. One saponifies in a double-walled kettle, first filling the lye into the kettle and adding some ready soap and heating to boiling. Now the fatty acids, which must be heated to 80°C, are added in a thin jet. At the end of the saponification, the excess caustic is determined by titration with phenolphthalein and adjusted to 0.1%. Whether the mass is completely saponified is determined by taking a sample from the kettle and dissolving it in absolute alcohol; this solution must remain clear, even after adding some ammonia. It is ensured that the soap contains so much water that it contains 65% fatty acid. The soap can be further improved by adding a few percent solvent, for example:
Tetraline 2 dl
Methylhexaline 3 dl
Turkish red oil 1 dl
Hexaline 3 dl
Carbon tetrachloride 1 dl
