The composition of the propellant
(57) Abstract:The invention relates to the production of propellants and compositions on their basis. The composition of the propellant comprises a mixture of tordiglione (halon 21) and diperchlorate (Halocarbon 22) in the ratio 80-70:20-30 wt.% respectively. The technical result - the composition of the propellant that meets the requirements for dilution capacity, steam pressure, inert to the active ingredients. table 4. The invention relates to the production of propellants and compositions on their basis. Propellants (Propellants) - substances that can be used to actuate (or transfer) of the other active substances (ADV). In aerosol containers are used, normally gaseous propellant in a compressed form. As active substances can be cosmetic, pharmaceutical preparations or compositions used for household or sanitary purposes, varnishes, paints, etc., For aerosol application in food products are typically used such propellants as nitrous oxide or carbon dioxide, aerosols, non-food products, such as cosmetics, insecticides, etc., until recently, was often used of different sources are called freons, or refrigerate, or halocarbons.Because there is a hypothesis about their destructive effect on the ozone layer of the atmosphere, these substances were banned by the Montreal Protocol.It was also established that the hydrogen-containing peroperty and chlorophenolate not destroy, or practically do not destroy stratospheric ozone. However, in the selection of substances for use as propellants takes into account a number of essential requirements.They should be non-toxic, non-flammable, have a definite boiling point, to have the necessary solubility of the active ingredients, chemically inert to the active current matter, to have a certain vapor pressure, providing a constant concentration of active ingredients. Freon should not affect the packing material (container) gasket or spray device.In addition to the qualities mentioned above, these substances must be commercially available.Dissolving ability of propellants is their ability to form a homogeneous liquid phase with the other components of the aerosol compositions, i.e., to be their solvents.
Freon 21 (CHCl2F) - 102;
Freon 11 (CCl3F) - 60;
Freon 113 (CCl2F-CClF2) - 31;
Freon 22 (CHClF2) - 25;
Freon 142b (CH3-CClF2) - 20;
Freon 12 (CCl2F2) - 18;
Freon 114 (CClF2-CClF2) - 12;
Freon 152a (CH3CHF2) - 11;
Freon, which is a stronger solvent - mainly those with an equal number of atoms of carbon and hydrogen have more chlorine atoms.

SUBSTANCE: method involves applying a composition comprising liposomes having gene structures encoding growth factors. The composition is administered for making injections into wound and impregnating materials for covering or closing wounds with the materials. Advanced bandage has coverage material and liposomes. Introducing liposome gene structures directly into wounds contributes to better healing results.
EFFECT: wide range of functional applications; enhanced treatment effectiveness and safety.

SUBSTANCE: invention proposes a cosmetic agent for prophylaxis of skin infectious diseases that comprises an active substance and a conducting agent - multilamellar liposomes additionally. As an active substance dioxydin is used in the amount 0.00001-0.02 wt.-% to the external agent mass. Method for prophylaxis of skin infectious diseases involves using a cosmetic agent in the form of spoon or shampoo, or gel, or cream in the dose depending on selection of the composition and properties of cosmetic agent. Applying the agent results to reducing injurious effect on skin normal microflora, reducing danger from penetration of preparation in blood and providing high protection of skin against all species of infection. Invention can be used for prophylaxis of skin diseases in humans.
EFFECT: valuable medicinal properties of agent.
