1. Potassium HydroxideMinor concernAlkali (lye). It is used up in the product: as a pH adjuster it neutralises an acid in the formula, and in soft or liquid 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.
