Technical Details & Test Data

Additional Information

Since Personal Care Solutions preservatives are based on dehydroacetic acid with a pKa of 5.27, there is more activity across a wider pH range compared to other acids like sorbic acid at 4.76.

Preservatives	pK Value	pH Range
		3	3.5	4	4.5	5	5.5	6	6.5	7
Dehydroacetic Acid	5.27	100%	98	95	86	65	37	15.9	5.6	1.9
Sorbic Acid	4.76	98	95	85	65	37	15	5.5	1.8	0.6
Formic Acid	3.75	85	64	36	15	5	1.8	0.6	0.2	0.06

The efficacy of Personal Care Solutions Preservative is pH dependent, offering greater efficacy at lower pH.

Minimum Inhibitory Concentrations (MIC) for Personal Care Solutions Preservative Compared to ParabensStudies were run using different concentrations of Personal Care Solutions Preservative in an anionic shampoo to see efficacy against various bacteria, yeast and fungi. All samples were inoculated at the beginning of the study, sampled at 24 hours, 3, 7, 14 and 28 days.
