Chelating agents - stability and clarity of cosmetic formulations

The category of chelating agents includes raw materials that bind metal ions (mainly Fe and Cu) present in water and raw materials. This reduces the risk of oxidation, discolouration and cloudiness, while promoting the effectiveness of preservatives in emulsions, gels, tonics and cleansers.

The range includes a plant-based phosphate chelator for nature-based formulations and a next-generation chelator based on an amino acid derivative. Both solutions are water-soluble and easily integrated into the aqueous phase at common dosages used in cosmetics.

Below you will find a brief overview with recommendations in which types of formulations these chelators have the most benefit.

Dermofeel PA-3 (Sodium Phytate)

A natural chelating agent based on sodium phytate. It improves colour and oxidation stability and enhances the preservation effect especially in aqueous and emulsion systems; also suitable for more "natural" positioning formulations. Natural chelator for clarity and stability with good biodegradability.For more information, please refer to Dermofeel PA-3.

Trilon M Max EcoBalanced (MGDA)

A new generation chelator based on MGDA (an amino acid derivative). Effectively binds hardness and metal ions, increasing clarity and stability in emulsions, gels and cleansers; also suitable for shampoo and shower products. A modern, effective chelator for a wide range of pH and formulation types.See Trilon M Max EcoBalanced for details.

FAQ - Frequently Asked Questions

Why include a chelator in the formulation?

A chelator binds metal ions from water and raw materials, reducing oxidation, discoloration and cloudiness while improving preservation efficiency. In practice, it contributes to longer stability and a more beautiful appearance of the product.

To which phase and in what order to add the chelator?

Most often to the aqueous phase at the beginning of the process. For emulsions, it acts on the ions already present during processing; for finished products, it can also be added in the cooling phase.

How to decide between Sodium Phytate and MGDA?

Sodium Phytate is suitable for natural focus and preservation support in aqueous systems; MGDA (Trilon M Max) is versatile, also effective in tenside products. Select according to formulation target and positioning.
