Abstract
Abstract Low molecular weight monoperoxyaliphatic acids such as peracetic acid are useful as broad spectrum biocides. An even broader spectrum of activity is achieved by selecting monoperoxyaliphatic acids having a carbon chain length of 6 to 9 atoms, which act as sporicides and in a wider pH range. A preferred biocide is peroxyheptanoic acid. The process can be carried out on solid surfaces such as in place equipment, or containers or in liquid media such as process or recirculating waters.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
55 words
A process for disinfecting solid surfaces or liquid media by bringing such an infected surface or medium into contact with an effective amount of a peroxyacid characterised in that the peroxyacid has the formula R-C0 3 H in which R represents an aliphatic hydrocarbon group having a carbon chain length of 5 to 8 atoms.
Claim 2
Dependent Claim
55 words
A process for disinfecting solid surfaces or liquid media by bringing such an infected surface or medium into contact with an effective amount of a peroxyacid characterised in that the peroxyacid has the formula R-C0 3 H in which R represents an aliphatic hydrocarbon group having a carbon chain length of 5 to 8 atoms.
Claim 3
Dependent Claim
19 words
A process according to claim 1 characterised in that the peroxyacid is a linear C 6 -C 10 monoperoxyacid.
Claim 4
Dependent Claim
