Over recent years, solid beauty bars have become a rising trend, either as shampoo, body wash, or hair conditioner. Syndet bars have been around for some time – the most well-known in the retail market is the Dove Beauty Bar, which can be used as a conventional soap bar for both body wash and shampoo.Continue reading
EURECO™ PAP is chemically known as Phthalimido peroxy hexanoic acid. Contrary to popular belief, it is not a “bleach activator” but a true peroxy bleach. Find out more about EURECO™ PAP in this handy guide by Norman Lowe, Senior Technical Consultant at HARKE UK & Ireland.
EURECO™ PAP is available in multiple formats:
In its liquid forms, EURECO™ is a suspension of PAP in water at a pH of 3.5. At this pH, PAP is insoluble and stable, yet still active.
To activate it fully, the pH must be raised. PAP becomes soluble and functions as an effective bleach and bactericide. However, it also begins to degrade in solution, making pre-mixed formulations unstable. Therefore, liquid grades must be dispensed at the point of use, primarily in industrial settings. EURECO™ RP103, as a coated granule, is stable and suited for incorporation into retail and commercial formulations like laundry powders, stain removers and auto dishwash powders/tablets.

| Fabric Type | Main Wash (g/kg) | Main Wash (g/L) | Rinse (g/kg) | Rinse (g/L) |
| Low Stained | 4.0–7.0 | 1.0–1.8 | 2.0–5.0 | 0.6–1.3 |
| Normal Stained | 7.0–10 | 1.7–2.5 | 5.0–8.0 | 1.2–2.1 |
| Heavily Stained | 10–16 | 2.8–4.2 | 8.0–10 | 2.1–3.2 |
(EURECO™ RP103, 9L Wash Volume)
| Staining Level | PAP (ppm) | RP103 (g/wash) |
| Normal | 100 | 1.45 |
| Heavily Stained | 200 | 2.9 |

Heat transfer fluids have many applications. They prevent machines from overheating, systems from freezing, and enclosed systems from corroding. These fluids are used in all types of mechanical engines, pumping systems, refrigeration and air-conditioning/heating systems, domestic and industrial heating systems, fire protection sprinkler systems, solar heating systems, undersoil heating systems (e.g., on football pitches), and geothermal heating systems.
The most efficient heat transfer fluid would simply be water. However, water has major limitations:
To solve these problems, glycols are typically used in heat transfer fluids. When blended with water in specific ratios, glycols lower the freezing point and raise the boiling point. Additionally, these blends include a highly effective anti-corrosion package that protects a wide range of metals.
At HARKE UK & Ireland, we are the agents for Clariant’s range of Antifrogen™ and Protectogen™ heat transfer fluids.
Antifrogen™ products are considered premium in the market. They guarantee long life and optimal efficiency, which is crucial since the systems they are used in are often very expensive. The relative low cost of the fluids helps reduce the risk of system failure and increases the time between refills, cutting operating costs.
Antifrogen™ fluids have been developed over many years and are tested far beyond standard conditions. For example, the standard corrosion test ASTM D1384 is performed at 88°C for 336 hours. Antifrogen™ products are tested at this standard and also at extended conditions: 1000 and 3000 hours at 180°C! These tests demonstrate both thermal stability and corrosion inhibition.
Test results are available and confirm the high performance and long in-use lifespans of these fluids. Get in touch for more information.
These products are not used neat. They are usually diluted with deionised water or, in some cases, soft mains water. Dilution levels vary by application and product type, typically between 20% to 50%.
Not all systems require ultra-long lifespans or extreme performance. For these cases, Protectogen™ grades offer a more economical option. Based on similar technology as Antifrogen™ but not tested to the same extremes, these fluids are suited for less complex systems.
HARKE UK & Ireland can supply both neat fluids in various pack sizes or ready-to-use dilutions. Comprehensive technical backup data is available to help you select the optimum product and dilution for your specific application. Get in touch today for more information – we’d love to hear from you.
