Definitions

  • the object of this invention is the protective gel for the hands, which forms a thin, elastic layer when drying and impermeable to organic substances. This layer protects the skin against the effects of oils, greases, tars and similar substances that come from crude oil, dust and other contaminants.
  • Hydrophilic creams, pastes and protective ointments which form an impermeable layer for the water-insoluble organic and fatty substances, are normally made on the basis of starch and glycerin with the addition of gel and neutral coating substances. Similar to the creams that are produced on the basis of casein, pectin or arabic gum, they form a continuous layer on the surface of the skin that can be easily washed off with soap and warm water.
  • these protective layers have a low mechanical strength and durability, so that they quickly lose their consistency and elasticity. This process can only be partially counteracted by adding stabilizers such as dextrin and alizarin oil.
  • Creams and protective gels are also known under the name invisible gloves, which are made on the basis of polyvinyl alcohol plasticized with glycerin. They form protective substances with very good mechanical properties that are physiologically neutral. Nevertheless, their application irritates the existing changes in the skin, such as skin aging, skin abrasion, skin eczema and skin scratch wounds. This creates an uncomfortable feeling of burning that discourages users from using this type of protection.
  • Another important defect of the known protective agents is their pH factor, which is equal to 7 or even higher than 7, which is very different from the pH factor of the skin, which is 5.5-6.0.
  • the purpose of this invention was such a gel for the hands which, while retaining all the known advantages of creams and hydrophilic ointments, has a soothing effect on the skin, but thanks to its great tightness and ability to reduce the surface tension on the skin, a thin, mechanically strong layer would not interfere with normal hand and finger movements at work, and would have a pH factor of 5.5-6.0.
  • this goal can be achieved by using a gel as the main component of a product from the reaction of casein with glycidol, with 100-100 parts by weight of glycidol per 100 parts by weight of casein.
  • the dry mass of the finished gel consists of 4-5.0-99.9% from the above product, to which an addition of 0.1-5.0 parts by weight per 100 parts by weight of the product in the reaction of the casein comes with glycidol, a Means that the surface tension of the
  • the protective gels for the hands show very good usage and protective properties. Thanks to the excellent consistency (tightness) and the reduction in surface tension, it can be applied very thinly and evenly. After drying out, an invisible and imperceptible forms Layer that shows no tendency to break, peel or roll.
  • the gel has the same pH factor as the skin.
  • the layer formed on the surface of the hands forms a very efficient protection for the skin of the hands from direct contact with the harmful, sometimes very toxic substances.
  • the application of such a thin protective layer on the hands reduces the drying time of this layer on the one hand and on the other hand it allows to wash off this layer quickly and easily after the work with the help of clear water and soap.
  • an additional advantage of the protective gel for the hands is its great stability during storage.
  • Example I In a reactor with a volume of 1 liter, which is equipped with a stirrer, reflux condenser and thermometer, 350 g of water, 200 g of casein and 15 g of 25% ammonia water are added. The whole thing is stirred constantly and at the same time the temperature is raised to 70 ° C in a water bath. Then 40 g of glycidol are added dropwise. After the dropwise addition of the glycidol, the temperature of the reaction mass is raised to 90 ° C. and allowed to remain constant for one hour. At the end of this time, the contents of the reactor are cooled to 50 ° C and diluted with 350 ml of the ethyl alcohol.
  • the pH factor of the reaction mass is set to 5.5-6.0 with the aid of a 30% water solution of acetic acid, for this purpose 2 g of a 40% water solution of the sodium salt of the ester of sulfonic succinic acid and the monoethanoluamide of the undezilenen are added acid added, which is manufactured under the name SBU 40% in the United Business Enterprises "INCO".
  • the resulting gel is applied in quantities of 3-5 g to clean, dry hands, distributed evenly and then left to dry for 3-4 minutes.
  • the applied protective gel does not let the hands dry out, does not interfere with the process of sweating hands, but is easy to spread on the skin. It nourishes and soothes the skin. Its color and smell are pleasant.
  • the gel In order for the gel to be fully effective, it should be applied 2-3 times during working hours, which coincides with the actual work breaks. After the work is done, the gel can be easily washed off with warm water and soap.
  • Example II Using the same procedure as in Example I, 200 g of gel are prepared, which are then 5 g of glycerin and 5 g of dextrin in the form of a 40% water solution and some color, e.g. Rodamin B or Congo can be added in red. The whole thing should be mixed up exactly.
  • the gel obtained can be applied in the form of a very thin layer, the layer formed after drying out is elastic and firm.
