You’ve probably heard the term `hydrosol’ mentioned more and more lately in the essential oil and aromatherapy world. Hydrosols have definitely become much more popular within the last 5 years, so it’s about time we learn a little more about them.
The definition of a hydrosol is a colloidal suspension in water. In simpler terms, a hydrosol is an aromatic water with therapeutic properties.
Some other names for a hydrosol are flower water, floral water, distillate, and hydrolat. Common hydrosols are a byproduct of steam distilled flowers, leaves, and fruits; they are technically just the water that is left over from the steam or hydro-distillation of an essential oil.
Don’t let the name “floral water” fool you! Hydrosols are more than just essential oils mixed in water. Did you know that it is common for some companies to market essential oils in water as hydrosols? Because of this, it is very important to purchase from a trusted source that can provide details about the product.
Some of the most recognized hydrosols in the industry would be Rose Hydrosol, Lavender Hydrosol, Chamomile Hydrosol, Peppermint Hydrosol, and Witch Hazel Hydrosol.
There are many different ways to extract the essence or essential oil from a plant. The most common and effective extraction that produces hydrosols is steam distillation.
During steam distillation, water vapor heats the parts of the plants, such as the roots, leaves, stems, flowers, or bark, to create their own steam. That steam then condenses into a liquid, and the essences of the plants are separated from the water. The most concentrated part of that separation is what we call ‘essential oils’. What is left over after the separation is the aromatic water or hydrosol.
Hydrosols are mostly water, containing only 1-2% of the same chemical constituents found in the volatile essential oil. However, hydrosols also contain the nonvolatile organic components that come from the plant that was distilled.
As part of the distillation process, it is also important to learn and support farms that properly use all parts of each precious plant. Many companies choose to cut corners by discarding what is thought to be unusable. While this may seem logical, such practices can decrease sustainability and waste control, which can ultimately weaken our planet’s ecosystem.
Because hydrosols are not a sterile product, they are notorious for growing bacteria or becoming contaminated. They can also degrade over time, so you should always refrigerate hydrosols to maintain their freshness, just like milk or juice.
Did you know that because hydrosols are so chemically different from essential oils, they aren’t actually a part of routine essential oil studies?
You can use hydrosols for many things, including DIY cleaning products, natural skin care, and aromatherapy practices.
They are most commonly combined with essential oils and used as a base or to replace water in linen sprays, facial toners, and natural body or room sprays. You can also use hydrosols as a base for fragrances or even facial cleansers.
Hydrosols are definitely an up-and-coming product that everyone should keep their eye on. When made properly with pure ingredients and sustainable practices, hydrosols can be an excellent and desirable tool to add to your cleaning, skin care, and aromatherapy purposes.
And hey! Who wouldn’t want to wake up and smell the Rose Water!
