Microfibrillated cellulose, branded as Valida, is manufactured by mechanically processing sustainably sourced cellulose wood fibres to their smallest components, while maintaining fibre length.
Suspension of this material in a water- or solvent-based solution will result in the formation of a highly interconnected 3-dimensional network capable of stabilizing all suspended particles or even oil-in-water droplets without the use of emulsifier. Due to the hydrophilic nature of cellulose, dermal
application will result in a hydrating skin feel, as opposed to a greasy, sticky or tacky skin feel when
using conventional thickeners or surfactants. Additionally, Valida shows thixotropic behavior, meaning that applying shear will significantly lower the viscosity, whereas removing shear will quickly restore viscosity. This allows for formulations to be sprayable and well-spreadable.
Microfibrillated cellulose is an excellent material to replace, or use in combination with, conventional
thickeners and surfactants in formulations, providing revolutionary possibilities in terms of formulation and end-user experience. Additionally, it is a bio-based, sustainably sourced and biodegradable material contributing to the innovating image of many companies.
