Kem Diol Preservative — the underrated powerhouse.
Looking for a broad-spectrum preservative that performs without the common headaches?
Let’s compare 👇
✨ Kem Diol
✔ Broad spectrum protection (bacteria, yeast & mold)
✔ Effective in a wide pH range
✔ More heat stable than many blends
✔ Compatible with surfactant systems
✔ Less odor impact than Geogard Ultra
✔ More flexible than Optiphen Plus in emulsions
Now stack it up:
▫ Optiphen Plus – Great for low pH systems but can destabilize emulsions and has usage limitations.
▫ Geogard Ultra – Natural-leaning, but strong odor and pH dependent.
▫ Germall Plus – Extremely effective, but not accepted in “natural-positioned” formulations.
💡 Kem Diol gives formulators flexibility, stability, and performance — without the drama.
