Water resistance is a desirable property across a wide range of product categories; from leave-on hair products and decorative cosmetics to sunscreens and skincare. Water resistance can be achieved many formulation approaches: a high concentration of non-polar emollients, specific combinations of waxes and resins, latex-based water-dispersible polymers, specific combinations of emulsifiers, and oil and water-soluble film-forming polymers.

See how texture analysis is playing a part in this methodology.

In connection to this article, while emulsifier systems and film-forming polymers may provide water resistance in emulsions, they’re also known to change the rheology profiles of semisolid systems; just how much is what Beverley Madlin and co-researchers at the London College of Fashion sought to determine. In this interview, recorded during the 2019 IFSCC Congress in Milan, Madlin explained what the researchers observed – including a “lesson learned” for what not to do.
