CALENDULA HYDROGLYCOLIC EXTRACT

Calendula hydroglycolic extract: what it is, how it's made and cosmetic uses

Calendula hydroglycolic extract is a cosmetic ingredient obtained by extracting the calendula plant (Calendula officinalis) using a mixture of glycerine and water as the solvent. This extraction method, very common in natural cosmetics, produces a plant extract without relying on alcoholic or organic solvents. This guide explains what a hydroglycolic extract is, how the calendula version is obtained, the type of cosmetic formulations where this kind of plant extract is used, and what to check before incorporating it into a product, without attributing properties not documented on its technical data sheet.

What is a hydroglycolic extract?

A hydroglycolic extract is a plant extract obtained by macerating or extracting a plant in a mixture of water and vegetable glycerine, instead of using alcohol or other organic solvents. Glycerine acts both as a solvent and as a partial natural preservative, thanks to its ability to lower the water activity of the medium.

This type of extraction is widely used in natural and organic cosmetics because it produces plant-derived ingredients compatible with formulations that aim to minimise synthetic solvents, keeping a water-based profile that is easy to incorporate into emulsions, gels and toners.

Calendula as a botanical raw material

Calendula (Calendula officinalis) is a plant of the Asteraceae family, traditionally cultivated in Europe and widely used as a raw material in cosmetics and herbal infusions. Its flowers are the part of the plant typically used to obtain extracts.

At Royal Bio, the technical data sheet for each batch of calendula hydroglycolic extract includes the specific analytical and organoleptic parameters of the product; we recommend consulting it before setting the usage percentage in a formulation.

Common uses of hydroglycolic extracts in cosmetics

Toners and enriched floral waters. Thanks to their water base, hydroglycolic extracts are easily incorporated into facial toners and cosmetic waters.

Emulsions and gels. They are added to the water phase of creams, lotions and gels, bringing the profile of the corresponding plant extract to the final formulation.

Certified natural and organic cosmetics. Their solvent-free extraction profile makes them compatible with the requirements of many natural and organic cosmetic certification labels.

How to choose a calendula hydroglycolic extract

Before incorporating any plant extract into a formulation, it is advisable to request the full technical data sheet from the supplier (botanical origin, extract ratio, preservation, organoleptic parameters) and the corresponding safety data sheet.

It is also recommended to run compatibility and stability tests in the final formula before moving to production, as with any new plant ingredient in a cosmetic development.
