Our HLD4 formula is Article 95 compliant and has been developed in line with the Biocidal Products Regulations (BPR), REACH, CLP (Classification of Labelling and Packaging) and CDG (Carriage of Dangerous Goods) regulations, to ensure that users are future-proofed against requiring changes to their product portfolios. Even under the strictest health and safety, occupational health, and environmental risk assessments, the HLD4 formula requires minimal consideration.

The synergistic blend of active and inert ingredients enables CHEMGENE HLD4L to work quicker than many other comparable disinfectant products.
