10 March 2003 00:00 [Source: ICB]Dow Chemical has launched a new business unit dedicated to developing novel emulsion and dispersion technologies for the personal care industry.
The business, named Dow Dispersion Sciences (DDS), aims to improve the process by which raw materials are incorporated into formulations, allowing its personal care customers to commercialise new products with improved functionality, at reduced costs and on faster timescales.
DDS' first commercialised technology is a proprietary mechanical dispersion technology. Combined with Dow's formulation, process and interfacial science know-how it enables production of emulsion concentrates (75-95% oil-in-water), with tightly controlled particle size of less than one micrometre and minimal surfactant.
DDS says the concentrates can be dispersed into customers' formulations with low shear and at ambient temperature, allowing for handling materials which are heat sensitive, shear sensitive or highly viscous.
The new business is initially focusing on a broad range of ingredients for the skincare and suncare markets. 'For example, with our technology we can dramatically enhance the efficacy of UV absorbers in formulated suncare and daily wear products,' says Sarah Eckersley, R&D leader for DDS.
DDS is offering its technology in three forms: raw material concentrates, custom preblends, and finished product formulations that are difficult to manufacture via traditional processes.
