Description
About
Titanium Dioxide Powder is a natural ingredient used to turn clear soap white.
Due to its brightness and very high refractive index, relatively low levels of it are required to achieve a white, fully opaque result. One of the major advantages for titanium dioxide is its resistance to discoloration under ultraviolet (UV) light in exposed applications, meaning your white soap stays white longer.
Info
Remember, too much will soften your soap and it may cause the excess to settle to the bottom as soap is cooling.
Titanium Dioxide is a natural mineral that can settle in your soap if care is not used. The best advice is this, after adding it to your soap, do not pour your soap immediately into your molds. Allow your soap to cool a bit and mix again right before pouring into molds. This allows the titanium dioxide to suspend better and the cooler soap helps it from settling too much.

LC50 > 10,000 mg/L — essentially nontoxic
IARC classifies titanium dioxide as Group 2B ("possibly carcinogenic to humans"), based on chronic inhalation studies in rats; IARC itself notes inadequate evidence of carcinogenicity in humans. OSHA and NTP do not identify titanium dioxide as a carcinogen at reportable thresholds. Not skin-sensitizing or eye-irritating per OECD-guideline animal testing. Not a PBT or vPvB substance.
WARNING: This product contains a chemical known to the State of California to cause cancer. Airborne, unbound particles of titanium dioxide of respirable size are known to the State of California to cause cancer. This listing does not cover titanium dioxide once it is bound within a finished product matrix (e.g., soap, lotion, or other cured formulation).
Disclaimer: The technical specifications above reflect standard production values and may vary slightly between batches. Always conduct your own small-batch testing and stability studies before scaling up to production.
