It is still working at \u003cstrong\u003e1 part in 200\u003c\/strong\u003e for light interior cleaning, and it can be used \u003cstrong\u003eneat\u003c\/strong\u003e for heavy industrial degreasing. Very few chemicals hold their performance across two orders of magnitude of dilution.\u003c\/p\u003e\u003ch2\u003eWhat's in it\u003c\/h2\u003e\u003cp\u003eBilt Hamber's SDS declares \u003cstrong\u003ealcohols C9-11 ethoxylated (3–10%)\u003c\/strong\u003e as the surfactant, \u003cstrong\u003edisodium metasilicate (1–3%)\u003c\/strong\u003e as the alkali builder, and \u003cstrong\u003etetrasodium etidronate — HEDP (1–3%)\u003c\/strong\u003e as the chelant. That last one is worth pausing on: HEDP is a phosphonate sequestrant. It locks up the calcium and magnesium ions in hard water so they can't precipitate out and rob your surfactant. It's why Surfex-HD keeps working in hard water where cheaper APCs go limp.\u003c\/p\u003e\u003cp\u003eThe silicate is doing the heavy lifting on pH. The SDS records \u003cstrong\u003epH 13.25\u003c\/strong\u003e — this is the most alkaline product in the Bilt Hamber range.\u003c\/p\u003e\u003ch2\u003eOn \"non-toxic\"\u003c\/h2\u003e\u003cp\u003eBilt Hamber describe Surfex-HD as \"zero VOC, biodegradable, non-toxic and pleasant to use.\" We'll pass on their claim about VOCs and biodegradability, but we're going to be straight with you about the last one: the product is CLP-classified \u003cstrong\u003eEye Dam. 1 (H318)\u003c\/strong\u003e and \u003cstrong\u003eSkin Irrit. 2 (H315)\u003c\/strong\u003e. \"Non-toxic\" there is colloquial, not toxicological.
