Saccharin Sodium
1. Basic Information
Name: Saccharin Sodium
Alias: Sodium o-Sulfobenzimide, Soluble Saccharin
CAS No.: 128-44-9
Molecular Formula: C7H4NNaO3S
Molecular Weight: 205.17
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder or colorless crystal
- Odor: Odorless, intense sweet taste with slight metallic aftertaste at high concentration
- Solubility: Freely soluble in H2O, soluble in CH3OH; slightly soluble in C2H5OH; insoluble in ether, benzene and aliphatic hydrocarbons
- Melting Point: Decomposes above 200 °C without distinct melting point
- Hygroscopicity: Moderately hygroscopic under high humidity
- Aqueous Characteristic: Neutral to weakly alkaline aqueous solution, sweetness is about 300–500 times that of sucrose
Chemical Properties
- Molecular Structure: Sodium salt of o-sulfobenzimide, containing cyclic imide and sulfonyl groups
- Acid-base Reaction: Reacts with strong acid to precipitate insoluble saccharin free acid
- Thermal Stability: Stable under normal processing temperature; decomposes at high temperature over 150 °C to release sulfur-containing impurities
- Photostability: Stable under ordinary light, no obvious discoloration after long-term storage
- Hydrolysis Resistance: Resists hydrolysis in neutral and weak acidic environment; slow hydrolysis under prolonged strong acid heating
- Compatibility: Compatible with most food raw materials and cosmetic formula components; incompatible with concentrated strong mineral acids
3. Main Application Fields
