Water-Soluble Red Colorant Stable at High pH (7.00+)

Based on your requirement for a water-soluble red colorant that is stable at high pH (7.00 and above), we recommend:

• WaterMix™ Red (Iron Oxides Red)

This product is a water dispersion of Iron Oxides Red. Iron oxides are known for their excellent stability across a wide range of pH levels, making them suitable for formulations with a pH of 7.00 or higher.

Other water-soluble red dyes like D&C Red and FD&C Red series, as well as natural colorants such as Beta-Carotene or Sorghum Red, may have varying stability depending on the specific product and the exact pH level. Iron oxides generally offer superior pH stability compared to many organic dyes and natural colorants.
