Guerlain has introduced an eco-focused pulse alcohol made by Intact Regenerative, featuring 'Pulse,' a low-carbon ethanol produced from legumes and their residues. The partnership produced a perfume-grade ultra-neutral alcohol designed to replace conventional neutral alcohols in fragrances.
Intact’s process transformed starch-rich by-products from peas and broad beans into ethanol via waterless extraction, fermentation, distillation and rectification, with cellulose fibers burned as the distillation fuel. The brand said production ran on renewable energy and delivered over 80% lower greenhouse gas emissions versus typical sugar-beet or wheat alcohols.
After two years of collaboration, Guerlain incorporated Pulse into 'L’Homme Idéal Cologne Forte' to lower the fragrance’s footprint while maintaining perfumery standards of homogeneity and stability. This debut highlights how ingredient-level switches can advance circular sourcing and soil-regeneration goals in beauty.

Why This Trend Is Growing
- Low-carbon Bioethanol
- New ethanol produced from legumes and residues reduces lifecycle emissions by over 80%, enabling substitutes for conventional neutral alcohols in perfumery.
- Waterless Extraction Processes
- The use of waterless extraction, fermentation and rectification creates concentrated feedstocks while cutting water use and enabling integrated energy recovery from cellulose fibers.
- Ingredient-level Carbon Reduction
- Swapping a single formulation ingredient for a regenerative-sourced alternative visibly lowers product footprints while preserving stability and sensory performance.
Industries Being Reshaped
- Fragrance and Perfumery
- Premium fragrance brands are positioned to market lower-carbon colognes that maintain olfactory integrity through adoption of ultra-neutral bioethanols.
- Cosmetic Ingredient Manufacturing
- Producers of neutral alcohols and solvent systems face demand for scalable, perfume-grade bioethanols produced with renewable energy and closed-loop processes.
- Agricultural Byproduct Valorization
- Processors of peas, broad beans and other starch-rich residues can unlock higher-value biochemical supply chains by converting waste into feedstock ethanol and energy.
