A process of sterilization or decontamination of apparatus, characterized in that an aqueous solution containing at least 0.01% of a compound of the formula ##STR1## in which R represents a C.sub.5 -C.sub.14 n-alkyl radical in the form of the base or a salt thereof, is applied to the apparatus at a temperature in the range of 30.degree. to 120.degree. C. at atmospheric pressure. The process is suitable in particular for the sterilization of milk processing circulation equipment.

Sterilization process using a heat effect additive

The invention relates to new chemical compounds and to processes for their preparation. The compounds according to the invention correspond to the formula

Hydroxylated amines with bacteriostatic activity

Pharmaceutical compositions the essential active ingredient of which is a biphenyl derivative, at least one of the phenyl nuclei of which has two adjacent hydroxyl groups, the two phenyl nuclei being separated by a carbon chain having one or two carbon atoms and in general, a double bend between two chain carbon atoms or between a chain carbon atom and a substituent thereof. The compositions are useful for the treatment of disorders of the blood micro-circulation.
