With LAB supply tight and DDBSA prices rising, Kemsurf SBE30 (LAS) is under pressure. Kemsurf OS38 (AOS) is built on a different alpha-olefin feedstock — sidestepping the bottleneck while matching or beating SBE30 across most sectors: higher, more stable foam, superior hard-water tolerance, better mildness, stronger cold-wash performance and ready biodegradability. From laundry and dishwash to personal care and firefighting foams, OS38 isn't a fallback — it's an upgrade.
