Sodium BorateBuffer
Classified as a Substance of Very High Concern (SVHC) under EU REACH for reproductive toxicity (Category 1B — may damage fertility and the unborn child). EFSA's tolerable upper intake from total boron exposure is 10 mg/day for adults; sodium borate dosing must stay well below this. Acute oral toxicity is moderate (lethal dose ~5–20 g in adults), but the chronic-exposure reproductive endpoint is the binding constraint. Largely phased out of modern supplements and personal care in favor of safer buffers (citrate, phosphate). If a current product lists sodium borate, the inclusion warrants scrutiny — there are safer alternatives for every excipient function it provides.
