Sustainable thermoresponsive whey protein- and chitosan-based oil-in-water emulsions for cosmetic applications.

An emulsion composed of 15 wt. % WP, 10 wt. % jojoba oil and 0.5 wt. % chitosan solution was found to have the greatest structural response to temperature. This study of an O/W emulsion containing whey protein concentrate and chitosan demonstrated that different oils and conditions can be used to tune thermoresponsive and rheological behaviour.
