   How sure we are

   High confidence. The label names this substance exactly.

2. Sodium HydroxideMinor concernAlkali (lye). It is used up in the product: as a pH adjuster it neutralises an acid in the formula, and in soap it turns the oils into soap. The EU caps the alkalinity it may leave (pH 11 for pH-adjuster use); the higher limits, with warnings, are only for hair straighteners, cuticle removers and depilatories.

3. Titanium DioxideMinor concernPermitted white pigment and UV filter. Inhaled titanium dioxide powder is a suspected carcinogen, so the EU restricts it in loose face powders and hair sprays and bars it from any product that could be breathed in; in creams, toothpaste and other non-sprayed products those limits do not come into play.
