The Materials Notebook
Iris Kemp
Materials specialist. Writes about what is in a sex toy, what is in a lubricant, what is in a piece of latex clothing, and what to do with it once you own it.
Iris writes the Materials & Care desk: the silicone-vs-glass comparisons, the latex care notes, the leather conditioning pieces, the "what is body-safe and what is not" explainers that sit at the technical heart of the site.
The editorial perspective here is consumer-rights led: there is no FDA-equivalent regulator for adult toys in the UK, so the buyer has to know what platinum-cure silicone actually is, why TPE eventually weeps plasticisers, and which condom materials tolerate which lubricants. Iris's pieces explain these one rule at a time.
Sources Iris draws on: the WHO/UNFPA Male Latex Condom Specification, the Public Health England guidance on body-safe materials, manufacturer technical data sheets, the academic literature on silicone-on-silicone bonding behaviour.
