Application and Stability Evaluation of Polymer blends in Cosmetics

Abstract

Objective: The use of polymers in the field of cosmetics has been popularized due to its properties of film-forming, emulsifiers, thickeners, rheology modifiers, stimuli-responsive agents, etc. The present work deals with the synthesis of polymer nanocomposites that has been incorporated into a base face mask formulation at a loading of 1% and subsequently studied for sensory attributes, primary skin irritancy and physical stability tests. Methods: The polymer nanocomposites were synthesised by the solution casting method and were incorporated in the base face mask formulation. Sensory evaluation was done using a ten member expert panel and the results were tabulated. The physical stability test was carried out at different storage conditions and the colour, odour, pH, viscosity and appearance were analysed using standard techniques. Results: The polymer nanocomposites were found to be stable in the face mask formulations for a period of 12 weeks. The sensory evaluation tests showed higher or equivalent results on most of the sensory parameters. The formulation showed no skin irritancy. Conclusion: The sensory and physical stability of the face mask formulation with the prepared polymer blend nanocomposite shows comparable and an equivalent match with base face mask formulation and also no irritation was found on using the face masks.
