Wetting agent for H2O2 solution I need to increase the wetting of an $\ce{H2O2}$ solution on ceramic surfaces. Does anyone know of a common chemical I can use for this?

The properties it would ideally have are:


Increases wetting of $\ce{H2O2}$ - water mixture on ceramics (particularly glazed tiles and tile grout).
Does not react or reacts very slowly with $\ce{H2O2}$ (and water).
Non-toxic / low toxicity. Food safe would be ideal.
Reaction products are non-toxic / low toxicity.
Reaction products are all either soluble in water or evaporate under atmospheric conditions.
Commonly available and reasonably cheap.
Non-foaming or anti-foaming.


Thank you so much to anyone who has a suggestion.
You might consider chlorhexidine gluconate. It is a cationic surfactant used as a skin cleanser and disinfectant prior to surgery, and is an ingredient in certain mouthwash products, so it must have low toxicity. Drug stores sell scented and unscented solutions for hand washing -- choose the unscented.
