Carrier Oil Viscosity

Meaning

The measure of a carrier oil’s resistance to flow, a physical property critical for compounding topical hormonal preparations, determining how easily a hormone solution can be applied and absorbed across the skin barrier. High viscosity oils are thick and slow to spread, potentially prolonging contact time, whereas low viscosity oils are thin and readily penetrate the skin. This property directly influences the rate of percutaneous hormone delivery and the final tactile feel of the compounded product, impacting patient adherence.
