Frequently Asked Questions

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

What do gelling agents and thickeners do in a cosmetic formula?

They help change the texture and flow of a product. They can make a formula thicker, turn a liquid into a gel, or improve stability and spreadability.

What is the difference between a gelling agent and a thickener?

A gelling agent is usually used to create a gel texture, while a thickener mainly increases viscosity. Some ingredients can do both, depending on the formula and how they are used.

Can I use a gelling agent or thickener on its own?

Some can be dispersed directly into water, while others need neutralising, heating, or premixing to work properly. Always follow the usage method for the specific ingredient you are using.

Why is my gel lumpy or uneven?

This usually happens when the powder is added too quickly, not dispersed properly, or added to the wrong phase. Slow addition and correct mixing method make a big difference.

Do thickeners and gelling agents preserve the product?

No. They change texture, but they do not protect a water-containing formula from bacteria, mould, or yeast. A suitable preservative is still usually needed.

Gelling agents are ingredients used in cosmetic formulation to thicken liquids and create stable gel textures. They help transform water-based formulations into smooth gels, serums and thicker cosmetic products.

Different gelling agents produce different textures, from light fluid gels to thicker, more structured formulations. They are commonly used to stabilise water-based systems and improve product consistency.

Gelling agents are widely used in products such as:

  • facial gels and serums
  • hair gels and styling products
  • thickened toners and cosmetic gels
  • water-based skincare formulations

This collection includes gelling agents suitable for both DIY makers and professional formulators looking to control texture, viscosity and stability in cosmetic products. Learn more in our guide: Fun With Plant Based Gels.
