If you want a pure rose water you should use pure distilled water while preparing rose water and no preservatives to be added to that.
You must be careful when purchasing rose water to buy only the 100 percent pure form. Often what is available in pharmacies and even some natural food stores is synthetic rose oil and water with preservatives added. Pure rose water is the distilled water of roses. It is usually made by stream distillation, and it smells heavenly and tastes delicious.
But some people use preservatives to store the same for long period ,they do as follows,
After the 150 ml rosewater has cooled you can add 1 tablespoon of alcohol, such as vodka, to the water as a preservative - shake to mix. Your rosewater will keep for about 4 weeks - longer if you store it in a refrigerator.
If you prefer to not add the alcohol as a preservative, your rosewater will keep for about 7 - 10 days.
Mix the rosewater with glycerin in a 50/50 mix and put the rosewater in a pretty bottle for a gift.
