Stratum Corneum Penetration Depth & Bio-Spicule Transdermal Delivery
Under passive topical application, molecules diffuse tortuously through intercellular lipids. Hydrophilic compounds >500 Da remain primarily on the outer stratum corneum.
pH Stability Window (0–14), Thermal Limit & HLB Colloidal Phase Behavior
Outside pH 3–10, risk of hydrolysis, viscosity loss, or ionic dissociation increases.
Thermally stable up to 85°C during standard emulsification.
