Abstract
A sanitizing composition comprises a solids mixture, usually pulverulent, of an iodine source such as an iodine-pvp complex, an acid source such as malic, sulphamic or other organic acid and an iodophor-forming surfactant. The composition can be used as such or can be dissolved in an aqueous solvent to provide high levels of biocidal activity.
Description
SPECIFICATION Improvements in and relating to santizing compositions
This invention relates to new sanitizing compositions which can be distributed and optionally applied in the dry (usually powdered) state but which can afford a highly biocidal iodophor on dissolution in water.
Iodine has for many years been used for skin disinfection and disinfection in vitrio. It has the disadvantages of poor solubility in water and it causes staining of skin and materials. It has largely been replaced by iodophors, being combinations of iodine with surfactants which act as carriers and solubiliziers for the iodine without loss of biocidal activity. They have the advantages over iodine of being almost odourless, non-irritant and non-staining.
lodophors exhibit maximum activity in acid solution, at pH4 or lower, and are marketed as liquids acidified with phosphoric acid, sometimes mixed with other mineral acids, the acid content amounting to about 27% phosphoric acid, and the iodine content to about 3%. However, the storage, transit and use of these acid concentrates present obvious problems.
It is an object of the invention to provide a dry, generally powdered composition which can be used to replace acidified liquid iodophors whilst generally avoiding their disadvantages.
The invention consists in a sanitizing composition comprising, in the dry state, an iodine source, a non-reducing acid source and a surfactant able to combine with the iodine from said source to form an iodophor.
The expression "iodine source" will be understood to mean a material which, on dissolution in water will provide iodine, directly or by chemical action. Suitable iodine sources include providone and iodine-pvp complexes.
The expression "acid source" will be understood to mean a material which, on dissolution in water, will provide an acid, directly or by chemical reaction.
Suitable acid sources include sulphamic acid, malic acid and succinic acid, with or without buffers, and acid phosphates such as dihydrogen sodium phosphate.
The surfactant can be anionic, non-ionic or cationic; in the latter case it may be itself contribute to the biocidal activity of the iodophor.
The iodine content of the composition may suitably range from 0.25% to 20% by weight. In the optimum composition at any given iodine concentration the acid strength will diminish as the iodine content increases.
The following examples illustrate how the invention may be carried into effect. The parts referred to are by weight, and the components are mixed in the dry, powdered state.
EXAMPLE 1 lodine-pvp complex 90.0%
Malic acid 4.7%
Sodium dodecyl benzene sulphonate 0.3%
EXAMPLE 2 lodine-pvp complex 2.4%
Suphamic acid 92.6%
Cetyl trimethyl ammonium bromide 5.0%
EXAMPLE 3 lodine-pvp complex 33.4%
Malic acid 30.8%
Sulphamic acid 30.8% Polyethanoxyalkyl ether 5.0%
The exemplified compositions have substantially improved biocidal properties compared with neutral iodine powders and are marginally more effective than acidified liquid iodophors.
1. A sanitizing composition comprising a solids mixture of an iodine source (as hereinbefore defined), an iodophor-forming surfactant and a non-reducing acid source (as hereinbefore defined).
2. A composition as claimed in Claim 1 wherein the iodine source is providone or an iodine-polyviny
Ipyrrolidone complex.
3. A composition as claimed in Claim 1 or Claim 2 wherein the surfactant is a cationic surfactant.
4. A composition as claimed in any one of Claims 1 to 3 wherein the acid source is sulphamic acid, malic acid, succinic acid or dihydrogen sodium phosphate.
5. A sanitizing composition substantially as hereinbefore described in any one of the foregoing specific examples.
6. A method of producing an acidified liquid iodophor for use as a sanitizing composition which process comprises bringing together an aqueous solvent and a composition as claimed in any preceding claim.
7. An acidified liquor iodophor whenever produced by a method as claimed in Claim 6.
