Definitions

  • the present invention relates to household aerosol compositions using a compressed gas propellant that are free of hydrocarbon propellants, and particularly the use of such compositions with metal aerosol canister that are capable of corrosion.
  • Examples of household aerosol products are air fresheners, car products, household products, fabric care, waxes, polishes, insecticides, ironing aids, fabric refreshers, and carpet cleaners.
  • Tinplating protects the metal canisters against rapid corrosion, but tends itself to dissolve in aqueous based formulations.
  • aerosol formulations containing less than 50 ppm of water corrosion of tinplated canisters is not generally a serious problem.
  • water content of an aerosol product is more than 50 ppm (and particularly when greater than 150 ppm), problems due to corrosion are more likely to occur.
  • VOC volatile organic content
  • non-VOC propellant such as compressed gas (compressed gas referring to compressed air, compressed nitrogen or mixtures thereof) since this is of less impact to the environment, less expensive than VOC propellant and safer to handle from a manufacturing perspective as well as a consumer perspective due to the likely reduction in flammability.
  • the common 'wet' (i.e. water rather than solvent based) air freshener aerosol compositions using VOC propellants typically contain nitrite as a corrosion inhibitor and sorbitan monooleate as an emulsifier to ensure uniform emulsification of water soluble and oily components such as water insoluble fragrance.
  • the best recognised inhibitor system for tin-plated canisters is sodium nitrite and morpholine. Morpholine is a volatile base that helps to preserve the vapour phase in the aerosol containers and gives an alkaline pH to the formula. This system can involve the formation of nitrosamines that are very carcinogenic.
  • sodium nitrite and morpholine are not generally able to prevent the dissolution of the tin coating, but to reduce the rate of dissolution of the tin coating to an acceptable level in VOC propellant systems.
  • the amount of morpholine, sodium nitrite and thickness of tin plate are designed for around the required shelf life, for example two years.
  • the dissolution of the tin plate to form a tin hydroxyl-oxide complex has been shown to have a negative effect on cleaning performances.
  • the tin complex generally gives a pale yellow to an intense yellow colour when deposited, especially when sprayed onto a white surface.
  • White fabrics or carpets can remain coloured by the liquids of aged aerosol products.
  • Other considerations relate to certain stains like coffee, tea and wine that contain cationic metals. These metals can form brown coloured complex with tin hydroxyl-oxide complex, causing an evident negative effect of the cleaning formulation and its overall cleaning performance.
  • an aerosol composition with compressed gas propellant that is free of hydrocarbon propellants, wherein the composition comprises:
  • composition is an air freshening composition.
  • the composition further comprises 0.00wt% to 0.5wt% sodium molybdate, and even more preferably comprises 0.0wt% to 0.1wt% sodium molybdate.
  • the composition comprises:
  • composition consists essentially of:
  • composition consists essentially of:
  • the compressed gas propellant used with the composition is preferably compressed air or compressed nitrogen or a mixture thereof.
  • the borate salt for use in the compositions of the present invention is preferably sodium borate, although other commercially available borate salts may be used either alone or in combination with sodium borate.
  • the low MW alcohol for use in the compositions of the present invention is preferably ethanol, although other commercially available low MW alcohols may be used either alone or in combination with ethanol.
  • an aerosol dispenser wherein the dispenser is a steel aerosol canister, tin-plated steel canister or other metal canister capable of corrosion and wherein the composition is an air freshener propelled, in use, by compressed gas propellant that is free of hydrocarbon propellants, the air freshener composition comprising:
  • corrosion is understood in the context of the present invention to refer to the disintegration of an engineered material into its constituent atoms due to chemical reactions with its surroundings, in particular in the context of metal canisters corrosion means electrochemical oxidation of the metal canister in reaction with an oxidant such as oxygen.
  • the dispenser is a steel aerosol canister or a tin-plate steel aerosol canister.
  • the composition further comprises 0.00wt% to 0.5wt% sodium molybdate, and even more preferably comprises 0.0wt% to 0.1 wt% sodium molybdate.
  • an anti-corrosion air freshening composition for use with a compressed gas propellant in a steel aerosol canister, tin-plated steel canister or other metal canister capable of corrosion wherein the composition comprises:
  • the dispenser is a steel aerosol canister or a tin-plate steel aerosol canister.
  • the composition further comprises 0.00wt% to 0.5wt% sodium molybdate, and even more preferably comprises 0.0wt% to 0.1wt% sodium molybdate.
  • the surfactant(s) used in the composition(s) of the present invention are preferably a non- ionic surfactant. More preferably the non-ionic surfactant(s) are ethoxylates of fatty alcohols, most preferably saturated C 8- 2o alcohols and the like, and most preferably saturated iso-C 13 alcohols such as those available from BASF under their LUTENSOL® brand of surfactants.

  • a fourth aspect of the present invention there is provided a method of preventing corrosion of a metal aerosol canister capable of corrosion wherein the method involves the step of introducing a composition according to the first or third aspect of the present invention into said aerosol container along with a compressed gas propellant that is free of hydrocarbon propellants.
  • Example 1 Two example formulations were prepared as set out below.
  • Example 1 Two example formulations were prepared as set out below.
  • wt% of the composition adds up to exactly 100wt%.
  • Each sample was then loaded into a tin-plated steel aerosol canister having a 15 bar pressure rating and filled with compressed air until the internal pressure within the canister reached 9.0 bar @ 20°C.
  • Samples of examples 1 & 2 were then held in a secure storage container at respective constant temperatures of 20°C, 30°C and 40°C for a period of 10 weeks and then tested for spray performance and, once exhausted, corrosion. All samples of examples 1 & 2 at all temperatures showed no signs of impairment after the storage, they all sprayed within consumer acceptable spray performance parameters and no canisters showed any signs of corrosion therein.
