A method of obtaining a solid soap

 

(57) Abstract:

The invention relates to the soap industry. The essence of the invention: production method of solid soap, including saponification of a mixture of fatty acids with caustic alkalis, wysilku, grind, sludge, removing padmaloka liquor and glue, introduction perezharivaya substances, drying the obtained soap base, the introduction of prescription supplements and mechanical processing, the saponification in the mixture of fatty acids enter of 0.05-5% glycerol by weight fatty acids, and as perejivaemogo substance use fatty acids, and the ratio of fatty acids and free caustic alkali containing soap base is 30:1-0,5:1. 1 C.p. f-crystals, 1 table.

A method of obtaining solid soap, which consists in saponification with caustic soda mixture of prescription fat raw materials taken in the form of neutral fat, Vyselki, grinding, sedimentation, drying the obtained soap base, the introduction of prescription supplements and mechanical processing. [1]

The disadvantages of this method is the complexity of the technological process and equipment design, consisting of the extraction of glycerol from padmaloka liquor. In addition, in this method the COI closest to the technical essence and the achieved effect is a method of obtaining a solid soap, including saponification of fatty materials in the form of fatty acids with caustic alkalis, wysilku, grind, sludge, removing padmaloka liquor and glue, introduction perezharivaya substances, drying the obtained soap base, the introduction of prescription supplements and machining [2]

But get this way the soap is of low quality, its physical-mechanical, physico-chemical, sensory and consumer properties are much smaller than soap derived from neutral fat.

Object of the invention is the obtaining of fatty acids solid soap of superior quality, quality indicators was not inferior to the quality Soaps derived from neutral fat, as well as the ability to create simultaneously washed as free and commercial purposes.

This task is solved in that in the method of obtaining a solid soap, involving saponification of a mixture of fatty acids with caustic alkalis, wysilku, grind, sludge, removing padmaloka liquor, introduction perezharivaya substances, drying the obtained soap base, the introduction of prescription supplements and mechanical processing, the saponification in the mixture of fatty acids enter of 0.05-5% glycerol by weight of fatty acids.

: Free caustic alkali, contained in the soap base is 30:1-0,5:1. This allows you to bind the excess alkali in the production process of soap, and when it is used. The resulting soap has a high cosmetic characteristics, does not dry hair, has a lower pH solutions, does not irritate the skin, has a beneficial effect on its water balance, does not damage synthetic fabrics in the wash.

With the introduction of the glycerol in the mixture of fatty acids, when the saponification improves the physical structure of the soap through the formation of a more durable and flexible micelles. The resulting soap has a high plasticity, improved uniformity, less swelling and cracking when it is used, has a higher frost resistance, the piece gets a shiny glossy surface.

The method is as follows.

Prescription a mixture of fatty acids added is 0.05-5% glycerol, mix, amyraut caustic alkalis, vymalivayut, grind, defend, remove podminky liquor and glue, ready-made soap base injected fatty acids with a ratio of fatty acids and free caustic alkali contained in the soap base is 30:1-0,5:1, dried under vacuum, introducing prescription supplements and subjected to mechanical the prototype.

As can be seen from the table, soap, obtained by the proposed method has a higher quality compared to the prototype, with an equal value of high-quality number and the same content of unsaponifiable substances and nomalanga fat, there is no free alkali, the hardness of the piece above and is 480-520 (prototype 458), this soap has a higher ductility equal to 45 (prototype 32), soap less swelling and cracking when using the value of this index is 3.6-4.2V (prototype 6), it has a higher organoleptic indicators of the distribution of the dye and the surface glossiness equal 7-9 points (prototype 5).

And the best is the introduction of glycerol in the amount of 0.05-5% by weight of fatty acids. When entering glycerol less than 0.05% goal not achieved due to the fact that the amount of glycerin is not enough for sustainable micellization. Enter glycerin in an amount of over 5% is impractical, as it does not lead to further improvement of quality indicators of soap.

When used as perezharivaya substances fatty acids is optimal ratio of fatty acids is more than 30:1 is the disruption of normal process conditions (stratification begins soap, worse drying processes and machining).

Introduction fatty acids of less than 0.5:1 is also impractical because of the free alkali is neutralized incomplete and the goal is not reached.

In the boiler acid load of 10 tons of a mixture of fatty acids of the following composition: 3 t fatty acids dietary fat, 2 t synthetic fatty acid fraction C10-C16, 2 t fatty acid salamaca, 3 tons of palm oil, heated to 85oWith and load 35 kg of glycerin, mix and amyraut 40% solution of caustic alkali, and then into the pot add 2 t of dry salt, mix and put on crap. After 2.5 h, poured podminky liquor. Mass boil with live steam under pressure of 1.5 ATM and add 0.5 t of hot water, after 6 hour of sludge from the boiler is pumped podminky glue and conduct chemical process control. In the finished soap base with stirring compressed air add 0.5 tonnes of fatty acids of sunflower oil. Received the soap base is dried in the vacuum drying tower under normal modes and add in the received chips with the 1% odorants, 0.3% of Anta, 0.3% Aluplast, 0.2% of titanium dioxide and 0.01% of the dye rhodamine and polyroot in the screw press.

The resulting soap with following assava proportion of unsaponifiable substances and nomalanga fat, 2,0

Hardness, g/cm 520

The degree of penetratie 44

Rastreskivalos and unmixing, score 4.1

The uniform distribution of the dye and the glossiness of the surface, the score

In addition, medical and clinical research, conducted by experts of the NGO "Cosmetology", soap samples, obtained by the proposed method showed high cosmetic properties, the absence of morphological violations of the structures of the skin, does not irritate her and does not cause allergic reactions.

Thus, this method allows you to get the soap of high quality free and commercial purposes. In fact, in both the soap improves its structure and neutralized free caustic alkali, which together can significantly improve the level of consumer properties of soap. Increases its cosmetic value (there is no harmful effect of free alkali on the skin, hair, synthetic fabric), increases the hardness of the piece, the manufacturability of its production, consumption decreases soap when used, extends shelf life and use, improving the appearance and color of the soap.

1. A method of obtaining a solid soap, including the saponification mixture iAUDIO substances, drying the obtained soap base, the introduction of prescription supplements and machining, characterized in that when the saponification in the mixture of fatty acids enter 0.05 to 5% glycerine by weight of fatty acids.

2. The method according to p. 1, characterized in that as perejivaemogo substance use fatty acids, and the ratio of beer acids and free caustic alkali contained in the soap base is 30 to 1 0.5 to 1.
