Abstract

This invention relates to bacteriostatic, fungistatic and algicidal compositions.

Said compositions comprise a metal derivative of N-hydroxypyridinethione of the formula: ##STR1## in which R represents a hydrogen atom, a lower alkyl radical, a lower alkoxy radical or a halogenated lower alkyl radical, together with a compound selected from the haloborates and the halosilicates.

Claims

1. A composition having bacteriostatic, fungistatic and algicidal properties comprising a zinc salt of a N-hydroxypyridinethione having the formula ##STR3## in which R is selected from the group consisting of hydrogen, lower alkyl, lower alkoxy and halogenated lower alkyl, and a fluorinated compound selected from the group consisting of potassium fluoborate and sodium fluosilicate, wherein the zinc salt and the fluorinated compound are present in a weight ratio of 1:

2 to 1;

10.

2. The composition as claimed in claim 1 comprising zinc N-hydroxypyridinethione and potassium fluoborate in a weight ratio of 1:

2 to 1;

10.

3. The composition as claimed in claim 1 comprising zinc N-hydroxypyridinethione and sodium fluosilicate in a weight ratio of 1:

2 to 1;
