- Function
Triethyl citrate is a functional solvent for preservation blends. It is combined with caprylyl glycol, a multifunctional wetting agent, and the well-known preservative benzoic acid to create GreenGard™ TBO. GreenGard™ TBO is suitable for fragrance-free formulas and allows you to work without Phenoxyethanol without compromising the biological stability of the products.

Technical Details & Test Data
- GreenGard™ TBO Microbiology Challenge
GreenGard™ TBO had its preservation properties tested in an O/W emulsion (1.3% usage rate, formulation pH of 5.13). A 28-day European Pharmacopoeia test was performed, in which the formula was challenge tested against Gram (+) & Gram (-) bacteria, yeast and mold inoculations.
Microbial species used for the challenge testing listed below:
Gram (+): S. aureus
Gram (-): P. aeruginosa, E. coli
Yeast: C. albicans
Mold: A. brasiliensisResults:
The formula showed a 99.99% reduction in cfu/g within 2 days of inoculation for the Gram (+) & (-) bacterial species, and after 7 days for the yeast and mold species. Reduction was maintained for the remainder of the trial.GreenGard™ TBO (1.3% in O/W emulsion, pH 5.13) European Pharmacopoeia Test
Figure 1 - GreenGard™ TBO reduction of cfu/g against bacteria, yeast and mold in an emulsion system. Total kill was observed for bacteria species after 2 days, and for yeast and mold species after 7 days. Reductions maintained forremainder of trial. Conclusion:
GreenGard™ TBO, when used at 1.30% in an O/W emulsion between pH 5.0 - 5.50, is a broad- spectrum, germicidal preservative. It is highly effective against Gram (+) & (-) bacteria, and effective against yeast and mold.
