Natural Preservative for Hydrosols
Hi, I was wondering what natural preservatives you find to be effective to preserve hydrosols once you open the bottle? This is a Geranium Hydrosol with a pH of 4.26.
I used Germall in the past, but would like to give a natural preservative system a go.
I know most suppliers of preserved hydrosols use Leucidal Liquid, but I’ve read that it is really not very effective.
I’ve seen the suggestion of 0.05% citric acid + 0.15% postassium sorbate. Is this enough?
I was thinking of using 1% Leucidal PE9010 + 1% Geogard Ultra + 3% natural Pentylene Glycol. Is this overkill?
