DDAC Biocide: Why GK Pro is the Superior Choice for External Cleaning

When it comes to maintaining pristine outdoor surfaces, the choice of active ingredient in your cleaning solution makes a significant difference.

At GK Products, we often encounter questions about the compounds we use, particularly regarding DDAC (Didecyldimethylammonium chloride) versus BAC (Benzylammonium chloride). While both are derived from soya beans and serve as biocides, their purity and performance in real-world applications set them worlds apart, much like comparing a single malt whisky to a blend, or extra virgin olive oil to standard olive oil.

DDAC vs BAC

We choose to formulate GK Pro exclusively with DDAC, which can be thought of as the "first press" of the soya bean - a purer, food-grade product. In contrast, BAC is typically an industrial-grade derivative, often extracted using additional alcohols, sulphates, and sodium salts to maximise yield from the soya bean stock. These impurities in BAC formulations can affect performance and are why BAC products are generally not permitted for use in food production or healthcare environments.

This purity translates directly to GK Pro's predictable and superior performance in the external cleaning sector. While some BAC products may struggle in hard water areas or exhibit erratic results, GK Pro, with its DDAC base, works consistently and reliably across all weather conditions and on a wide range of surfaces. This unwavering performance is why we confidently supply GK Pro, ensuring professional cleaners achieve excellent results every time.

Why Choose GK Pro?

Beyond its immediate cleaning power, GK Pro offers long-term residual cleaning benefits. Its DDAC nature means it continues to actively kill newly arriving spores for at least two years after treatment, depending on environmental conditions. As these spores are slow-growing, you can expect to see no new significant growth for at least two years post-treatment.

This extended protective action provides incredible value. For instance, GK Pro's impressive dilution rate allows it to go further: one 5-litre tub, when diluted at 50:1 (1 litre of product to 50 litres of water), can treat over 1,000 square metres of rendered walls at an application rate of 0.25L per square metre.

This remarkable coverage combined with its lasting effect makes GK Pro a truly cost-effective and high-performing choice for maintaining outdoor surfaces at a professional level.

Summary

When it comes to professional outdoor cleaning, GK Pro is the obvious choice. This DDAC biocide works consistently and reliably across all weather conditions, and can be utilised for cleaning across a wide range of surfaces. It will continue to kill any newly arriving spores for a minimum of two years after treatment to keep outdoor areas pristine for longer.
