Frequently Asked Questions

Answers to common questions about choosing and using Essentially Natural ingredients.

What does a chelating agent do in a cosmetic formula?

A chelating agent helps bind trace metal ions that may be present in water or raw materials. This can help improve formula stability and reduce the risk of unwanted changes in colour, scent, or performance.

Is a chelating agent the same as a preservative?

No, they are not the same. A chelating agent does not replace a preservative, but it may support the preservative system by helping create a more stable formula environment.

Do I need a chelating agent if I am using distilled water?

Sometimes yes. Even if your water is purified, trace metals can still come from other raw materials, equipment, or packaging, so a chelating agent may still be helpful in some formulations.

Will a chelating agent change the texture or feel of my formula?

Usually it is used at low levels, so it does not have a major effect on texture. The exact result depends on the formula and the specific chelating agent being used.

Can chelating agents help with hard water in rinse-off products?

Yes, they are often used in shampoos, cleansers, and body washes to help reduce the effect of minerals in hard water. This can support better product performance and a cleaner rinse.

Chelating agents are ingredients used in cosmetic formulation to bind metal ions that may be present in water or raw materials. By binding these trace metals, chelating agents help improve formulation stability and support the effectiveness of preservative systems.

Metal ions can contribute to oxidation, colour changes and reduced preservative performance in cosmetic products. Chelating agents help minimise these effects, improving the overall stability and shelf life of formulations.
