RhéologieIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : We present an innovative, natural and readily biodegradable suspension agent that opens new possibilities to homecare formulators. When added to detergent formulas, it brings a very powerful suspension capacity without any perceivable impact on viscosity. The agent is based on activated cellulose fibers obtained through the fermentation of starch using specific bacterial strains. We present rheology measurements that allow us to predict the suspension power of a detergent formula supplemented with the agent, based on its rheology at low shear rates. The yield stress value extracted from Bingham plots highly correlates with the density and size of the objects that can be suspended with the agent. We show the application of the agent in multiple home care formulations, in particular the suspension of decorative visual beads and concentrated fragrance in a typical liquid laundry formula. We describe how it is simple to add the suspension agent to a formula due to its pre-activated liquid format. A formula supplemented with the suspension agent is stable for several months at 45°C, with sustained suspension power and no demixion or change in aspect, highlighting the suitability of the suspension agent for commercial consumer products.

Vaisselle -- NettoyageIndex. décimale : 668.5 Parfums et cosmétiques Résumé : A good skimming ability as well as a good, long-lasting lather white simultaneously achieving a good cleaning efficiency, particularly on baked-on food residues, plus an acceptable price-performance ratio are the main properties consumers primarily look for in dishwashing agents. The developing foam has an important signal effect on the performance of the hand dishwashing detergent. The key to this is a combination of surfactants and polymers by which an intensive long-lasting foam and a high effectiveness to remove baked-on food residues will be obtained.

Stabilité chimiqueIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The personal and home care market is under continual development and raw material manufacturers need to develop new products to anticipate new consumer needs and regulation evolutions.
Hygiene and care products are an integral part of our daily lives, and unfortunately the same goes for plastics. It is present in large quantities in cosmetics and home care products, mostly in the form of synthetic polymers that are used for instance for exfoliation, opacification or rheology modification.
However, in recent years, the use of plastics and especially microplastics is at the heart of many controversies and debates due to their impact on the environment and health. It is required to find some alternatives.
In this context, Solvay has developed a naturally-derived biodegradable opacifying agent to replace the existing solution based on Styrene/Acrylates Copolymer.Note de contenu : - MATERIALS : Mackadet OPR-2 - Styrene/acrylates copolymer - Fomulations
