Foam is a key indicator of efficacy and performance for a range of consumer pharmaceutical and food products. A company seeks cost-effective physical and mechanical technologies for enhanced foam generation and stability. Devices that are able to generate a high volume of foam from low-concentration, surfactant-based formulations are especially of interest. Possible solutions include packaging technologies that alter the ingress of fluid dynamics in a surfactant-containing cage, or that impact the entrapment of air in a squeezable bottle or aerosol. Nozzles and pharmaceutical/dermatological foam-generation devices are also suitable options.
