Formulation

How to specify these extracts

Scalp serums and tonics are mostly water or hydro-alcoholic leave-on systems, so water-phase botanical extracts are the natural fit and can be used at higher levels than in rinse-off products. Butylene glycol and Zemea® propanediol carriers keep clear tonics clear; glycerin suits scalp masks and creams. Usage level and clarity are confirmed by your lab against the Spec Sheet and a sample.
Every Part ID above is a single-plant, cosmetic-grade liquid extract made by Bio-Botanica's Bio-Chelated® cold process, supplied full-spectrum and non-standardized. Glycerin (GL), Zemea® propanediol (ZB) and butylene glycol (NBG, PBBG) are carriers, not extraction solvents.
