This field of work is one in which our team of scientists specialise having gained an international reputation over a long period of time. We continue to develop and improve the technology in order to further enhance performance whilst bringing down costs. The range of active ingredients and applications studied at R&B Research is very extensive but our work would include:
- Development of multi-active (carbamate + pyrethroid + nicotinoid) insecticide microemulsion for the control of resistant bed bugs where we were able to significantly improve the speed of knock-down , reduce the LC50 values and improve residuality in a highly stable formulation.
- Development of a highly concentrated organophosphate formulation where the use of a novel and innovative carrier/ surfactant system allowed us to achieve loadings much above expectations. When compared to conventional formulations the efficacy in the field was circa 2-3 times better.
- Development of a natural plant extract formulation where we were able to increase the efficacy levels to the point where it was equivalent to conventional synthetic triazole fungicides with far superior dilution stability and rain-fastness.
- Development of techniques to examine the effectiveness of microemulsions to control the movement and positioning of active ingredients on to soil when applied through surface treatment.
- Development and testing of a very wide range of products for application in the agrochemical, professional pest control, timber treatment and home & garden sectors where a variety of approaches are needed to meet the diverse challenges of the various sectors.
In developing microemulsion formulations we would use an array of different techniques some of which we have developed and adapted in our own laboratories but these would include:
- Measurement of interfacial tension as part of the surfactant selection process
- The use of detailed phase mapping to elucidate the structural changes following water enrichment
- The use of detailed conductivity profiling to predict stability of microemulsions
- Particle size analysis and turbidity to study the stability of dilutions or of o/w RTU systems
- The use of drop shape analysis to determine dynamic contact angle and to study the wetting and spreading properties of dilutions and the effect of selective additives
- Analytical techniques linked to centrifugation to determine phase stability of microemulsions
- In house phytotoxicity studies to aid in selection of safer surfactant systems
