Propellant for aerosol packaging
(57) Abstract:Application: aerosol compositions in the household. The inventive propellant for aerosol packaging contains, by weight. % : Halocarbon 12 - 44,5; an organic solvent (propane - butane mixture) 11 and tetramethylsilane was - 44,5 that provides improved consumer properties. table 2. The invention relates to aerosol compositions, in particular to the propellants for aerosol packages used in the household.As propellants use individual compound having a vapor pressure at 21about4.2 ATM, for example, chloroformate or atany (halons), propane - butane mixture, the vinyl chloride etc.For household aerosol products in different countries as a propellant, the most widespread such compositions: grade a mixture of Halocarbon 11 and halon 12 - 1 : 1, the propellant UV-1A, in which halon 11 - to 44.5 wt. % halon 12 - to 44.5 wt. % , propane - butane 11 wt. % .The disadvantages of these compositions is the presence of components of halon 11 (C easiness to undergo hydrolysis in the presence of water to form hydrochloric acid). In certain conditions, anhydrous ethyl alcohol can vysmxoy harmful to the ozone layer of the atmosphere. Halocarbon 11 sufficiently toxic to warm-blooded and causes skin irritation.Known composition for aerosol packages containing DICHLORODIFLUOROMETHANE (freon 12), an organic solvent and silicone connection dimethylpolysiloxane 1 - 10 wt. % and other organic components.The disadvantage of these compositions is that dimethylpolysiloxane is not a propellant that creates pressure in aerosol packaging. In addition, polymethylsiloxane containing terminal hydroxyl groups, are inclined in the aquatic environment to polymerization zagustevanii overall composition.To improve consumer properties and expanding the resource base propellant for aerosol packaging contains, by weight. % : Halocarbon 12 - 44,5; an organic solvent 11 and tetramethylsilane 44,5.Tetramethylsilane was is a colorless, odorless inert liquid having a boiling point of 26 - 27aboutWith density - 0.65 g/cm3with high stability to hydrolysis and resistance to heat - endure many days of heating at 500aboutC.It is known the use of tetramethylsilane as internal standard in NMR spectroscopy. Use tetramethylsilane compounds, used as a propellant, it has no destructive effect on the ozone layer of the atmosphere, has a very low toxicity to warm-blooded animals, does not cause irritated skin.Description evakuiruyut mixture are given in table. 1.The proposed propellant can be used in detergents, polishes, cosmetics. Testing of products in aerosol cans, including those containing water components is carried out to determine the excess pressure vapor and aerosol, percent output the contents of the aerosol packaging per unit of time for example 1 : (propellant TMS) as an analogue of the most used in the production of propellant UV-1A(TU 6-15-625-83) composition, wt. % : Halocarbon 11 : propellant Ohr : Halocarbon 12, equal to 44.5 : 11,0 : 44,5, in comparison with standard formulations (table. 2).In the trial established that excessive vapor pressure drugs, containing propellant TMS does not exceed 8 kg/cm2 at the maximum allowable for aluminum cylinders 12 kgf/cm2. Thus, the actual pressure in this case is 1.5 times less than the ultimate strength of the packaging.P R I m e R 1. The propellant composition (propellant TMS), wt is telego mixing the components in a conventional capacitive device, maintaining the temperature in the apparatus (-10) - (15)aboutWith further experience in aerosol packaging composition:
Cleaner "Second" TU 6-15-404-87
Air freshener "Aromatic" THE 6-40-5703417-12-83
Hairspray, "the Beauty Suite" THE 6-15-12-76-80
Antistatic agent "antique" THE 6-40-0204318-5-91
The results are presented in table. 2 in comparison with the results of industrial propellant brand UV-1A (TU 6-15-626-83).The flow rate of the aerosol package with new propellants does not differ from the corresponding values of known compounds.New propellant provides output the contents of the aerosol packaging not less than 98.4% of when the requirement of the standard is not less than 95 - 97% .Under natural and accelerated conditions at 40aboutWith over 1 wt corrosion on the inner surface of the cylinders is missing.The use of the invention allows to expand the raw material base, to reduce the use of environmentally hazardous products, to reduce the cost of perfumery-cosmetic products.
