Limonene
Description
Limonene (CAS 138-86-3), also sold as dipentene in its racemic form, is a naturally derived terpene solvent and fragrance ingredient sourced primarily from citrus peel oils.
It functions as a bio-based alternative to petroleum solvents in cleaning and degreasing applications, and as a flavoring and scent ingredient across food and personal care markets.
In industrial cleaning and printing, this compound cuts through inks, adhesives, and greases on press equipment and packaging lines, replacing harsher hydrocarbon solvents.
Food manufacturers use it as a flavoring agent to deliver citrus character in beverages, confectionery, and baked goods. Personal care formulators incorporate it into fragrance blends.
It is used in shampoos and skin cleansers where a fresh citrus scent profile is required. It also functions as a carrier solvent in fragrance concentrates, improving dispersion of active ingredients.
The product is supplied as a clear mobile liquid in drum and IBC quantities, with bulk tanker options for high-volume buyers. It is available in food-grade and technical-grade specifications.
The food-grade material meets FCC standards. Both the d-limonene and racemic dipentene forms are commercially stocked, with purity levels typically ranging from 95% to 99%+ depending on grade.
