Abstract

An enhanced biocidal composition based on grapefruit seed extract is suitable for use on a variety of surfaces including skin. The composition includes a mixture of acids, e.g. glycolic acid which acts as a secondary biocide and lactic acid which acts as a pH buffer, which is part-neutralised by addition of an organic or inorganic base to bring the final pH to within the range of 4 to 5. Aminotrimethylene phosphonic acid enhances the biocidal properties. An aqueous carrier incorporating an organic solvent, an oil/water coupling agent, a surface wetting agent and a surfactant provide improved surface cleaning and a prolonged period of activity. A skin emollient is included for dermal use, and a preservative ensures long shelf life.

Claims

26. A biocidal composition according to Claim 1 which includes a buffering agent.
27. A biocidal composition according to Claim 26 in which the buffering agent is lactic acid.
28. A biocidal composition according to Claim 26 in which the proportion of buffering agent is between 0.5 % and 2.0 % of the composition by weight.
29. A biocidal composition according to Claim 1 which includes a skin emollient.
30. A biocidal composition according to Claim 29 in which the skin emollient is propylene glycol.
31. A biocidal composition according to Claim 29 in which the proportion of skin emollient is between 1.0 and 3.0 % of the composition by weight.
32. A biocidal composition according to Claim 1 which includes a preservative.
