| Also known as floral waters, hydrosols are by- products of the steam distillation of plant materials. While essential oils are concentrated forms of plant essences, hydrosols are highly diluted, made up of variable ratios of plant materials to water. To protect consumers, standards are being developed to determine an acceptable ratio. Quality hydrosols are beneficial to skin and hair, but do not offer all the synergy of natural, unprocessed plant liquids (e.g., aloe vera and orange pith juice). |
