Solution for Liquid Soap/Shampoo Separation

The issue of your liquid soap or shampoo separating into layers after adding SugarThick is because SugarThick (PEG-120 Methyl Glucose Dioleate) acts primarily as a thickener, increasing the viscosity of the formula. However, it does not provide the necessary stability to prevent different components from separating over time, especially if there are other ingredients or variations in density.

To solve this problem and create a stable, uniform liquid soap or shampoo that does not separate, you need to incorporate a stabilizing agent. A common and effective stabilizer for liquid detergent systems is Xanthan Gum.

How Xanthan Gum Helps

Xanthan Gum creates a gel-like network throughout the liquid. This network helps to suspend other ingredients evenly within the formula, preventing them from settling or separating into layers. It provides yield stress, meaning the formula maintains its structure when at rest but flows easily when shaken or poured.

How to Incorporate Xanthan Gum

Typically, Xanthan Gum is used at a low concentration (often 0.1-1%). It needs to be properly dispersed to hydrate and form the gel network. A common method is to:

1. Disperse the Xanthan Gum powder in a small amount of glycerin or a non-polar oil first (if your formula contains these). This helps prevent clumping.
2. Slowly add this dispersion to the water phase of your formula while stirring vigorously or using a high-speed mixer until a uniform gel forms.
3. Alternatively, you can slowly sprinkle the Xanthan Gum powder directly into the water phase while mixing continuously at high speed until fully hydrated and thickened.

By adding a suitable grade of Xanthan Gum, you can achieve a stable, non-separating liquid soap or shampoo with a consistent texture.
