Limewater is a saturated calcium hydroxide solution, Ca(OH)2, produced by mixing air lime with water. Air lime dissolves in water (not entirely) and the filtrate obtained becomes the limewater as it is known. Family hardware business use to prepare liniments and hygiene products with it. Limewater is also a basic product in biology and chemistry laboratories, used to show the presence of carbon dioxide. Among its other most famous uses, we can find it in aquariums (bringing limestone to corals) or used for lime filler’s frescoes.

To apply your mixture, use disposable or reusable cotton. Only prepare small quantities in order, for the oil, to not oxidise (rancid odour) and, for the emulsion, to be better stored.
