Maltodextrin (CAS 9050-36-6) — Citrus N/A Note Fragrance Ingredient
Maltodextrin
CAS 9050-36-6
What Is Maltodextrin?
Maltodextrin is a common food additive and fragrance carrier derived from starch. You’ll find it in everything from processed foods to powdered drinks as a thickener or filler. In perfumery, it serves as a stabilizer and delivery system for volatile fragrance compounds. While odorless itself, maltodextrin helps control the release of scents in products like solid perfumes and scented powders.
Safety Profile
GENERALLY SAFEWhat Does Maltodextrin Smell Like?
Maltodextrin is completely odorless, functioning as a neutral carrier rather than an aromatic ingredient. Its molecular structure binds with fragrance oils without contributing any scent of its own. When used in powder formulations, it creates a smooth, non-gritty texture that evenly distributes fragrance molecules for consistent scent delivery upon application.
Chemistry, Properties & Perfumer Guide
The Chemistry
Maltodextrin is a polysaccharide produced by partial hydrolysis of starch, typically from corn, rice, potato or wheat. The manufacturing process breaks down starch molecules into shorter chains of glucose units, creating a water-soluble powder. The degree of hydrolysis determines the dextrose equivalent (DE) value, which affects properties like sweetness and viscosity. In perfumery, maltodextrin acts as a physical carrier rather than participating in chemical interactions with fragrance compounds.

Classic Accords
Tip: Use finer particle sizes for smoother texture in powder applications.
Alternatives & Comparisons
Offers superior molecular encapsulation for controlled release applications but is more expensive than maltodextrin.
Provides better oil absorption for liquid fragrances but creates a drier, more powdery feel.
Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. Consult current IFRA Standards Library before formulating.
IFRA Status
No IFRA restrictions apply to maltodextrin.
RIFM Assessment
RIFM considers maltodextrin safe for all cosmetic applications.
Sustainability
Maltodextrin is typically derived from renewable plant sources like corn or potatoes. The production process is energy-intensive but yields a biodegradable material. Synthetic alternatives exist but often lack the same environmental profile. Sourcing from non-GMO or organic crops can improve sustainability credentials for natural product formulations.
