LegalizeCommission Implementing Regulation (EU) 2026/1337 of 17 June 2026 granting a Union authorisation for the biocidal product family Ecolab Glut Family in accordance with Regulation (EU) No 528/2012 of the European Parliament and of the Council
This is the act as published. Later amendments are not folded into the text below: each one is a separate act in this repository and an entry in this law's history.
Wear chemical resistant gloves meeting the requirements of European Standard EN 374 or equivalent for connecting/disconnecting intermediate bulk containers (glove material to be specified by the authorisation holder within the product information).
If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the hydrotesting fluid. This concentration can be achieved either by slow release and/or long retention times resulting in sufficient degradation of glutaraldehyde and/or by dilution with unpolluted water, and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Hydrotesting water up to 750 mg/L glutaraldehyde can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.
If small volumes have to be disposed of or if it is not possible to reduce the concentration to 0,2 mg/l, the fluid can be released to seawater directly by reducing the blowdown rate to allow sufficient dilution in seawater. The required reduction is locational and depends strongly on e.g. flow velocity.
To avoid the development of resistance: in addition to the requirements in the general instructions for use, check the efficacy of the product on site.
If needed, causes of reduced efficacy must be investigated to ensure that there is no resistance or to identify potential resistance.

4.10.1. Use-specific instructions for use
For the control of bacteria responsible for spoilage, deterioration, gas evolution, odour, pH/viscosity changes, disintegration of formulations, slime, and corrosion. The product should be added directly to the water phase where adequate mixing will ensure quick dissolution. In hot process, allow the temperature to fall below 40 °C prior to addition.
The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, consult the manufacturer of the preservative product, to determine the dosage requirements for the specific matrix to be preserved or determine the dosage experimentally. The lowest effective dose should be used.
4.10.2. Use-specific risk mitigation measures

For all procedures where undiluted biocidal product is openly handled (such as mixing and loading, entering pumps into drums, repairing pumps or connecting lines) the following risk mitigation measures must be followed, unless they can be replaced by technical and/or organisational measures:
- — Use of respiratory protective equipment (RPE) providing a protection factor of at least 10 according to EN 14387 or equivalent is mandatory. At least a powered air purifying respirator with helmet/hood/mask (TH1/TM1), or a full mask with combination filter gas/P2 is required (filter Type A/ Type A-P2) to be specified by the authorisation holder within the product information). The user must be trained in the correct use of the prescribed RPE.
- — Wear protective chemical resistant gloves meeting the requirements of European Standard EN 374 or equivalent during product handling phase (glove material to be specified by the authorisation holder within the product information).
