Within the personal care sector, products such as creams, pastes, lotions and ointments can often be applied via squeezing from a tube or bottle. The viscosity of such products defines how they flow from the container and also how they are applied to the body.
How the product is dispensed from a container will depend on its viscosity response to the shear rate applied. Squeezing from a tube is a moderate to lower shear rate deformation. The KELTROL® CG xanthan gum family has pseudoplastic rheological properties that makes it easy to pump. CEKOL® cellulose gum can be selected to give good pumpability and have a more constant viscosity across various shear rates. CEKOL cellulose gum can also provide a continuous, non-lumpy pourability, and a smooth honey-like rheology.
Gelling polymers such as GENUVISCO® CG-131 carrageenan and KELCOGEL® CG-LA gellan gum, can modify the flow pattern, giving shorter, non-stringy flow and a cleaner break.
