Blue Ultramarine

Blue Ultramarine – Intense Blue Pigment for Soap & Cosmetics

A Classic Blue Pigment with a Rich History

Originally derived from lapis lazuli, Blue Ultramarine is now safely and consistently produced using kaolin clay, sodium carbonate, and sulphur, fired in a kiln to achieve its traditional deep blue hue. This versatile, cosmetic-grade pigment is ideal for soaps, cosmetics, and other beauty applications.

Key Benefits

• Deep, Vibrant Blue – A rich pigment perfect for soaps and cosmetics.
• Cold Process Soap Safe – May release a temporary sulphur scent that disappears during curing.
• Smooth Application – Best mixed with oil, glycerine, or pre-traced soap for even dispersion.
• Cosmetic Use – Suitable for makeup formulations (check local regulations for eye safety).

Usage Recommendations

• Cold Process Soap – Blend with oil or pre-traced soap for best results.
• Melt & Pour Soap – Mix well before adding to the base.
• Not Recommended for Bath Bombs – May react with high-pH environments.
• Best Used in Products with pH Below 7 – Ensures optimal color stability.
