How to create a shimmer effect in liquid soap?

Beautiful, iridescent liquid soap is more than just a hygiene product; it's a true cosmetic accessory that will enhance your bathroom and make your daily routine more enjoyable. One of the most stunning ways to achieve shimmer is by using a preserving agent.

In this article, we'll explain how to easily and safely create shimmering soap with a rich pearlescent sheen.

1. Why preserving agent?

Preserving agent are special ingredients that impart a soft, pearlescent shine to aqueous surfactant-based foaming soaps without creating large sparkles. Their advantages:

- Delicate, refined shine – reminiscent of natural pearls
- Uniform distribution – does not settle to the bottom of the bottle
- Safety – based on ingredients approved for use in cosmetics
- Versatility – compatible with various bases

2. Step-by-step instructions for adding preserving agent:

Step 1.

Prepare the surfactant solution and stir until smooth.
Step 2.
Add the preserving agent in the required dosage. Stir by hand or with a magnetic stirrer.
Step 3.
Add the required amount of dye and fragrance and stir.
Step 4.
Add sodium chloride. Stir by hand or with a magnetic stirrer until the salt is completely dissolved and the mixture thickens to form a gel of the desired viscosity.

3. How to enhance the effect?

• Colored shimmer: add liquid dye (blue + pearl = aqua effect)
• Increase the dosage of preserving agent to enhance the shimmer intensity
