Amylopectin, acid-hydrolyzed, 1-octenylbutanedioate (CAS 113894-85-2) — Citrus Fixative Note Fragrance Ingredient
Amylopectin, acid-hydrolyzed, 1-octenylbutanedioate
CAS 113894-85-2
What Is Amylopectin, acid-hydrolyzed, 1-octenylbutanedioate?
Amylopectin, acid-hydrolyzed, 1-octenylbutanedioate is a modified starch derivative used in fragrance encapsulation and controlled release systems. It helps stabilize volatile compounds in perfumes and functional fragrances. This ingredient matters because it enables longer-lasting scents in products like air fresheners and fabric conditioners, where gradual fragrance release is desired.
Safety Profile
GENERALLY SAFEWhat Does Amylopectin, acid-hydrolyzed, 1-octenylbutanedioate Smell Like?
This modified starch has no inherent odor but serves as a molecular scaffold for fragrance delivery. Its structure creates a porous network that traps aroma molecules, releasing them gradually like a time-released capsule. Performance varies based on the parent starch’s molecular weight and degree of substitution.
Chemistry, Properties & Perfumer Guide
The Chemistry
Amylopectin derivatives are created through acid hydrolysis followed by esterification with octenyl succinic anhydride. The process reduces molecular weight while introducing hydrophobic side chains. These modifications transform water-soluble starch into an amphiphilic material capable of encapsulating both polar and non-polar fragrance compounds through a combination of hydrogen bonding and hydrophobic interactions.
