Description
Toilet Cleaner and Descaler (TCD) is a unique product for cleaning and maintaining toilet and black water systems on trains and in stations. The product combines an excellent moderately acidic, bio-based cleaning chemistry with scale prevention and scale removal technology.
In addition, TCD contains a widely approved antimicrobial agent to offer an additional level of biosecurity to passengers and crew. The active antimicrobial ingredient is supported under the EU Biocidal Product Regulations for product type 2 (incl. toilet cleaners), registered by the US EPA and is approved for the Design for the Environment (DfE). It is also registered as a preservative for detergents at the Bra Miljöval in Sweden and has a generally Regarded as Safe (GRAS) status.
The active ingredient has a dual-action antibacterial mechanism and passes EN1276. It is also active against many common viruses and passes EN14476 at the in use concentrations.
The above performance requires the use of specific surfactants at a pH of between 3-4. The product pH is between these levels and in use the descaling action causes the pH to rise to a level downstream of the toilet where its biocidal action ceases. When black water enters the sewage treatment system it will not affect performance. The formulation is readily biodegradable.
