How to specify these extracts
Sunscreen bases are emulsions with a high actives load, so water-phase botanical extracts are added at low levels in the cool-down phase. Glycerin and Zemea® propanediol carriers suit mineral and hybrid systems; butylene glycol suits lightweight fluids and sprays. Compatibility with the UV filter system, pH and preservative is 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.
