Abstract
Overview
ISO 7836:2024 - Natural rubber - Identification of phytosterols, including β-sitosterol specifies a laboratory method to detect the presence (presence/absence) of phytosterols, notably , in natural rubber in raw, vulcanised and latex forms. The standard uses followed by with comparison to a β‑sitosterol standard. Results confirm whether natural rubber (which uniquely contains β‑sitosterol among cis‑1,4‑polyisoprene rubbers) is present.
