Sucrose benzoate refers broadly to the benzoyl esters of sucrose.
The sugar molecule (sucrose) contains multiple hydroxyl groups (–OH), which can be esterified with benzoic acid derivatives to yield mono-, di-, and poly‑benzoyl esters up to the octa‑ester (octabenzoate).
Industrial materials sold under the name "sucrose benzoate" usually consist of highly benzoylated sucrose (often predominantly hepta- or octa‑benzoates) and are used as specialty plasticizers and tackifiers due to their high glass transition modifying effect, glossy films and good compatibility with many polymer systems.
This article treats the substance both as a defined molecular entity and as a commercial product family, describing the common commercial compositions, representative molecular species, and how composition affects performance.
Nomenclature, synonyms and identifiers
Common names and synonyms encountered in the literature and commercial catalogs include:

Key identifiers commonly cited for commercial sucrose benzoate material:
CAS number (commercial product commonly sold as "sucrose benzoate"): 12738-64-6
EINECS / EC Number: 235-795-5 (as listed in commercial spec sheets)
Molecular structure and variants
Sucrose (α‑D‑glucopyranosyl‑(1→2)‑β‑D‑fructofuranoside) contains eight free hydroxyl groups (five on the glucose unit and three on the fructose unit depending on counting), allowing formation of esters in multiple substitution patterns.
The benzoylation of sucrose yields a series of esters:
Monobenzoyl sucrose (one benzoate per sucrose)
Polybenzoyl sucroses (di‑, tri‑, etc.)
Hepta‑ and octa‑benzoyl sucrose (highly benzoylated species)
Commercial "sucrose benzoate" materials are typically dominated by high‑ester content species (hepta‑/octa‑benzoyl sucrose), which gives them the physical properties desirable for use as plasticizers and gloss agents.
Physical and chemical properties
Commercial technical sheets report the following representative properties (note: exact values vary by grade and manufacturer):
Appearance: white to off‑white crystalline powder
Melting / softening point: approximately ~93–101 °C (varies with grade)
Solubility: nearly insoluble in water (very low aqueous solubility; reported values on the order of milligrams per liter), soluble in aromatics, ketones, esters, chlorinated solvents and many organic solvents used in coatings and plastics
Density: typical values reported near ~1.20–1.35 g·cm⁻³ depending on grade and measurement temperature
Refractive index: reported in supplier data
LogP / partitioning: hydrophobic due to multiple benzoyl groups; miscibility in non‑polar organic phases is high
Odor: negligible or faint benzoyl odor in technical grades
Because the material is a saccharide ester, its chemical stability is influenced by hydrolysis (especially under acidic or basic conditions at elevated temperature) which can cleave benzoate esters to release benzoic acid and regenerate free sucrose hydroxyls.
