Purox® S Scopeblue® is an ultra-high purity sodium benzoate (≥99.9%) from LANXESS, with validated sustainability benefits. It is produced from renewable feedstocks — specifically used cooking oil — making it partially upcycled. A mass balance approach is used throughout production. This makes it the first sodium benzoate on the market with a measurably reduced carbon footprint, supported by a validated Product Carbon Footprint (PCF) evaluation aligned with scope 3 reduction targets.
Life Cycle Assessment (LCA) data underpins these claims. Compared to conventional sodium benzoate, resource use drops by a factor of 6.5. Ecotoxicity impacts — linked to processing chemicals used in conventional production — are also significantly reduced, as is acidification.
Purox® S Scopeblue® meets USP/NF, FCC, Ph.Eur, BP, and JP pharmacopeial standards and is registered as EU food additive E211. It brings pharmaceutical-grade rigour to cosmetic preservation without compromising on green credentials. The ingredient is Kosher (including for Passover) and Halal certified, and manufactured under FSSC 22000 and FAMI-QS quality management systems. It is a premium, compliance-ready choice for brands with high sustainability and quality benchmarks.
Key Benefits
- Exceptional purity — minimum 99.9% sodium benzoate. Sets an industry benchmark for this material class. Supports use in sensitive personal care and multi-sector applications
- Renewable and upcycled feedstock — produced from used cooking oil via a mass balance approach. Delivers a measurably lower carbon footprint compared to conventional sodium benzoate. Validated by LCA and PCF evaluation
- Dramatic reduction in environmental impact — LCA data shows resource use falls by a factor of 6.5. Ecotoxicity and acidification impacts are also significantly reduced versus conventional grades
- Broad-spectrum antimicrobial activity — effective against bacteria, yeasts, and moulds. Can be used as a standalone preservative or in synergistic combinations with other antimicrobials and multifunctionals
- Wide regulatory acceptance — certified to USP/NF, FCC, Ph.Eur, BP, and JP. Listed as E211 under EU food additives legislation. Suitable for cosmetic use under Annex V of the EU Cosmetics Regulation
- Multi-sector compliance — Kosher, Halal, FSSC 22000, and FAMI-QS certified. Simplifies supply chain qualification for cross-sector formulators
- Supports sustainable brand positioning — renewable origin, upcycled feedstock, and validated carbon footprint data support eco-conscious formulation claims
