Goal: Stability & Preservation

Ingredients designed for stability, safety, and formulation longevity

Stability and preservation systems ensure formulations remain safe, effective, and consistent throughout their intended shelf life.

This collection includes preservatives, chelating agents, and stabilisers selected to support product integrity across both rinse-off and leave-on systems.

From water-based systems to emulsions and long-term stable formulations.

Serums & water systems

Preservation systems designed for high-water, low-viscosity formulations.

Phenoxyethanol & Caprylyl Glycol Preservative, Disodium EDTA

Creams & emulsions

Preservation and stability support for oil and water systems.

Phenoxyethanol & Caprylyl Glycol Preservative, Disodium EDTA, Glyceryl Stearate Citrate

Cleansers & rinse-off

Systems requiring preservation across surfactant-based formulations.

Phenoxyethanol & Caprylyl Glycol Preservative, Disodium EDTA

Multi-phase systems

Systems requiring preservation across surfactant-based formulations.

Phenoxyethanol & Caprylyl Glycol Preservative, Disodium EDTA

A practical approach to building safe, stable and well-preserved formulations.

Start with a formulation appropriate for the intended system and use.

Select a preservative system suited to the formulation type.

Frequently asked questions

Practical answers to common questions about this formulation goal.

What is the role of preservatives in formulations?

Preservatives protect formulations from microbial growth, helping maintain product safety during use and storage.

Why is preservation important in water-based products?

Water creates an environment where microorganisms can grow, making preservation essential for safety and stability.

What does a chelating agent do?

Chelating agents bind metal ions that can destabilise formulations or reduce preservative effectiveness.

How does pH affectstability?

pH influences ingredient compatibility, preservative performance and overall formulation stability.

Can I formulatewithout a preservative?

Water-based formulations require preservation. Anhydrous systems may not require preservatives but still need stability considerations.

Are these ingredients suitable for beginners?

Yes, but preservation should be approached carefully. Following recommended usage levels and understanding system requirements is essential.
