Maltodextrin
A polysaccharide-based formulation excipient and encapsulation matrix used in spray and serum formulations. Primary function is as a textural stabiliser and encapsulation vehicle.
Benefits
- Stabilises active ingredient encapsulation
- Film-forming for spray applications
- Humectant at high concentrations
- Carrier matrix for powder formulations
- Contributes to texture and skin feel
Example uses
- Spray encapsulation vehicles
- Serum formulations
- Powder cosmetic binders
- Dry shampoo formulas
- Encapsulated active delivery systems
Mechanism of action
Functions as an amorphous matrix in encapsulation systems, trapping and stabilising volatile or sensitive actives until application. Film-forming on skin surface via hydrogen bonding. Mild humectant via polysaccharide water absorption. No pharmacological mechanism.
Clinical evidence · High
Well-characterised excipient with extensive use history. Safety confirmed by CIR.
Effective concentration range
1–5% (excipient); q.s.
Formulation notes
Water-soluble; functions across cosmetic pH range. Starch-derived; corn, potato, or tapioca sources available for allergen considerations.
Watchouts
No significant skin-active function — primarily a formulation excipient. May contribute to microbial growth in poorly preserved aqueous systems.
