FACTORY TECHNOLOGIES AT HOME - SIMPLE RECIPES
Face powder. Simple recipes and tips Directory / Factory technology at home - simple recipes toilet powder is mainly a mixture of organic and mineral substances, which are turned into the finest powder and processed accordingly. Powder aims, on the one hand, to protect the skin from external influences and to absorb the moisture released by the skin; on the other hand, it aims to give the skin a more delicate and lighter shade than it actually is. Therefore, in order for the powder to fulfill these purposes, it is necessary that it adhere well to the skin, since only in this case can it fulfill its purpose. In addition, it should cover the skin well, i.e. its individual particles must adhere so tightly to each other that a layer of a known thickness is obtained and the skin under the powder would not be visible. For these reasons, starchy substances are especially suitable for powder, which have the ability to adhere to the skin and cover it with an even layer. Since, in the manufacture of powder, attention should be paid to ensuring that it does not become a paste consistency, which is especially possible in a hot climate where the human body sweats profusely, rice flour (rice starch) was used for this purpose. As you know, of all organic powders, rice flour is the least susceptible to sticking, in addition, it has all the qualities desired for a good powder. Along with rice starch, magnesia carbonate, talc, calcium carbonate, barium sulfate, bismuth and zinc oxide are also used to make powder. Magnesia carbonate, unusually light, is sometimes used separately for powder, just like rice flour, without any other admixture; but it does not lay down in such a dense even layer as rice flour. Of the mineral substances, talc has the greatest use, and only the highest grades of Austrian talc are suitable for the manufacture of powders - completely white and the smallest; gray varieties should not be used for this purpose. In addition, purified matte-white calcium carbonate and barium sulfate are used to prepare the powder. If it is required to make fatty powders, for example for the stage, then fat is added to the powder in the form of a powder. Thanks to this impurity, this powder adheres to the skin much better than ordinary powder. To mix fat into the powder, there are special devices that spray the fat and evenly distribute it in the powder. But if instead of lanolin we take the best grade of vaseline oil, then such expensive devices will not be required at all. You can add vaseline oil in small portions to the already mixed powder and then sift all the powder through the drum again. The action will be the same. If the powder is not produced in very large quantities, then drums with sieves are used for sifting it. After the prepared mass is sifted, proceed to its aromatization. For this purpose, all liquid and crystalline, natural and artificial odorous substances are used. They are used in liquid form, with crystalline odorants being dissolved in liquid odorants or in alcohol. Then this mixture of perfumes is added, with constant stirring, to the prepared powder, and then the perfumed mass is again sifted through a sieve. If the powder needs to be dyed, then this is done before adding the perfume, already for the reason that if the wrong shade were obtained, then the smell of the perfume would not disappear in vain during repeated sieving. For the same reason, spirits are added after the first sifting, so as not to strangle large particles left on the sieve in vain. Ready powder is usually stored in a box upholstered in tin. And to store the powder in more hygienic conditions, it is recommended to keep the finished powder in cylindrical tins, which have a sloping bottom, and an opening with a sliding door at the bottom in front. When you move the door away, the required amount of powder is poured into the substituted boxes. Powder bases I. For expensive varieties
II. For cheap varieties
Powder Colors I. Pink color is achieved by staining with a solution of eosin in vodka. II. The flesh color is obtained by coloring with a solution of Ponceau aniline dye in vodka. III. The color "raschel" is achieved by coloring with a solution of burnt sugar in vodka. IV. Violet color is achieved by coloring with aniline dye methyl violet in vodka. Note: Violet is currently very fashionable and very effective in electric lighting. Purple powder is used with great success by film actors and before taking photographs. Perfumes for powder A wide variety of substances are used to perfume powder: essential oils, concentrated perfumes, and especially such newest artificial odorants as ionone, geraniol; ambretole, coumarin, vanillin, etc. Oily powder Take 2 parts of anhydrous lonolin and dissolve it in 8 parts of ethyl ether, then add 20 parts of wheat starch and grind it in a porcelain mortar. At the same time, 1 part of boric acid (in powder), 20 parts of talc and 2 parts of bismuth chloride are mixed, a mixture of starch and lanolin, previously dried until the ether has completely evaporated, is mixed in and essential oils or perfumes are added for smell. Or take 7 parts of talc and wash it with water. While still wet, mix it with 4 parts of powdered spermaceti, then dry and add perfume as desired. Liquid powder Dissolve 5 parts of boric acid, 20 parts of borax in 75 parts of cologne. If desired, the liquid can be tinted in a pale pink color (eosin), flesh color (Ponceau), raschel color (burnt sugar), purple (methyl violet). Liquid powder is used as follows: using a cotton swab, moisten the face with liquid. After a few minutes, the cologne evaporates, and a delicate coating of borax and boric acid remains on the skin.
