Description

Process for the preparation of durable lecithin emulsions for therapeutic use Purposes The property of the lecithin of vegetable and animal origin, in water It is known to swell and thereby form permanent emulsions. On the other hand succeeds it not; to produce such durable emulsions when adding to the mixture of Lecithin and water are fatty oil and paraffin oil or one of these two substances.

As has now been found, such emulsions can be used in addition to lecithin of vegetable or animal origin water, fatty oil and, if necessary, paraffin contain, of extraordinarily great durability, if you use pine oil or Adds mixtures of pine oil and other terpene compounds.

Such durable and non-segregating lecithin, pine oil, fatty Aqueous emulsions containing oil and paraffin oil are for therapeutic purposes very suitable, especially for protecting the skin against sunburn while at the same time Achieving a healthy tan and for rubbing against rheumatic diseases.

The emulsion has a dissolving effect on the fat and dirt parts of the skin a. The terpene compounds create a stronger blood flow to the rubbed Areas of the skin while the lecithin is absorbed by the skin. The additions of Fatty oil and paraffin oil act as excellent lubricants when massaging.

When making the emulsion, however, one does not have to rely on start from the relatively expensive pure lecithin. Rather, it exists the possibility of a water- and oil-containing vegetable lecithin emulsion, as z. B. in very large quantities as a by-product in the extraction of soybean oil from soybeans is obtained to use fresh for this purpose.

When extracting the soybeans, for example with gasoline at the same time triggered considerable amounts of the lecithin present in the beans. The lecithin is initially colloidally dissolved in the oil, from which it separates prolonged standing and sits on the ground. But there- this self-elimination takes a very long time and in this way only a spoiled, If very inferior lecithin can be obtained, excretion becomes expedient by introducing relaxed steam into the 01 accelerated. The lecithin swells up with the steam condensed into water in the oil, and sits on the floor and is used here as a lecithin-oil-water mixture, which is usually called soy sludge designated, separated. Most of the oil can be removed by centrifugation, so that now an emulsion is obtained which, for. B. from 3 5 parts lecithin, 15 Parts of oil and 50 parts of water.

In order to avoid a decomposition of this emulsion by fermentation, was the water from the fresh soy mud since then immediately under vacuum evaporated, so that a durable mixture of z. B. 7o parts of lecithin and 3o parts Oil is obtained. This lecithin-oil mixture can be used to carry out the invention Find use. But it also has the great advantage that you can buy for the same Purpose can use the fresh water-containing soy mud by z. B. with a mixture of pine oil, turpentine oil, otherwise with the addition of Paraffin oil and additional amounts of water and fatty oil by stirring and shaking vigorously emulsified in a suitable device. So it succeeds in this way. the Convert otherwise easily perishable soy sludge immediately into a long-lasting emulsion.

For example, 8 parts of soy lecithin are used to carry out the invention with an oil content of 30 0, lo, which by -Trocknexi voli fresh soy mud ,. have been obtained with 15 parts pine oil, 12 parts turpentine oil, 10 parts paraffin oil and _S5 parts. Water emulsified by vigorous stirring. Furthermore, you can z. B. so process that 16 parts of fresh soy sludge with a content of 35% lecithin, 15% oil, 50% water with 15 parts pine oil, 12 parts turpentine oil, 10 parts refined Soybean oil and 47 parts of water are emulsified.
