Starch, hydrogen octenylbutanedioate (CAS 52906-93-1) — Citrus None Note Fragrance Ingredient
Starch, hydrogen octenylbutanedioate
CAS 52906-93-1
What Is Starch, hydrogen octenylbutanedioate?
Starch, hydrogen octenylbutanedioate is a modified starch used primarily as a stabilizer and emulsifier in cosmetics and food products. You’ll find it in lotions, creams, and some processed foods where texture modification is needed. This ingredient matters because it improves product consistency without adding fragrance, making it a workhorse ingredient in formulations where maintaining neutral sensory properties is crucial.
Safety Profile
GENERALLY SAFEWhat Does Starch, hydrogen octenylbutanedioate Smell Like?
This modified starch is odorless by design, serving as a neutral base in formulations rather than contributing aromatic properties. Its complete lack of scent makes it ideal for applications where other fragrance components need to shine without interference from the carrier system.
Chemistry, Properties & Perfumer Guide
The Chemistry
Starch, hydrogen octenylbutanedioate is a chemically modified carbohydrate created by esterifying starch with octenyl succinic anhydride. This modification introduces hydrophobic side chains to the normally hydrophilic starch molecule, giving it amphiphilic properties. The synthesis involves reacting starch under alkaline conditions with the anhydride, followed by purification to remove reaction byproducts. The degree of substitution is carefully controlled to achieve desired functional properties while maintaining food-grade safety.

Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. Consult current IFRA Standards Library before formulating.
IFRA Status
Not restricted by IFRA – classified as a non-fragrance ingredient.
RIFM Assessment
Not evaluated by RIFM as it is not considered a fragrance material.
Sustainability
This synthetic ingredient is derived from renewable starch sources, typically corn or potato. While the modification process requires chemical inputs, the base material is biodegradable. Production scale allows for efficient manufacturing with relatively low environmental impact compared to petrochemical-derived stabilizers.
