Silicone incorporation into an esterquat based fabric softener in presence of guar polymers

Résumé

Fabric softeners are widely used to make clothes soft and impart nice smell. Household conditioners are water-based formulations consisting of quaternary ammonium surfactants assembled in vesicles. On the other hand, formulations used for textiles finishing are typically silicone oil emulsions. Here, these technologies are combined in a novel industrial formulation which contains both surfactant vesicles and silicone oil. In particular, we insert an amino-modified silicone oil into a recently developed softener comprising vesicles of an esterquat and guar polymers. Two strategies based on the use of esterquat or guar gum as stabilizers for the silicone incorporation in the fabric softener are proposed. Dynamic light scattering (DLS), cryogenic transmission electron microscopy (cryo-TEM), optical and fluorescent microscopy are applied to study the stability and the insertion of the silicone oil into the softener. It is shown that silicone oil is stabilized by the surfactant and the guar gum in nano-or micro-metric droplets. The vesicles structure and properties are not affected by the silicone oil while the formulation's stability is preserved. These findings suggest that the proposed route for adding silicone oil into a topical conditioner is a promising route for multipurpose fabric softener development.
