Preventing Color Bleeding in Multi-Colored Soap

To prevent colors from bleeding into each other when making soap with multiple colors, it is recommended to use pigments instead of dyes.

• Dyes are water-soluble colorants. In a soap base, which contains water, dyes can dissolve and migrate over time, causing colors to bleed and mix.
• Pigments, on the other hand, are insoluble particles that are dispersed throughout the soap base. Because they do not dissolve, they are much less likely to migrate and cause bleeding, helping the distinct color layers or sections remain sharp over time.

Look for pigments specifically designed for soap making. Examples include:

• Fluorescent Pigments
• Mica powders
• Iron Oxides

Using insoluble pigments will help maintain the separation and vibrancy of multiple colors in your soap bars.
