Industrial Applications of Dulcitol
| Industry | Application | Process |
|---|---|---|
| Food Industry | Used as a low-calorie sweetener or sugar substitute in diabetic foods and sugar-free confectionery | Fermentation or chemical synthesis |
| Pharmaceuticals | Used in the preparation of laxatives or osmotic diuretics for the treatment of constipation or elevated intracranial pressure | Chemical synthesis or biotransformation |
| Cosmetics | Used as a humectant or emollient in skin care formulations to enhance skin hydration | Purification or chemical modification |
| Laboratory Research | Used as a biochemical reagent for microbial culture or enzyme activity studies | High-purity crystallization or chromatographic separation |
| Feed Additives | Used as an energy supplement in animal feed to support digestion and nutrient absorption | Industrial-scale fermentation production |
Manufacturing Quality Control of Dulcitol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Galactitol Content) | HPLC with Refractive Index Detection | Separation on a carbohydrate-specific column followed by quantification based on refractive index response relative to a calibration curve. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and base in methanol to quantify water via stoichiometric reaction. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral galactitol molecules in solution at specified concentration and temperature. |
| pH (10% aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity using a calibrated glass electrode system in a 10% w/v aqueous solution. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead-specific hollow cathode lamp and air-acetylene flame. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid followed by high-temperature ashing; residue weight reflects inorganic impurities. |
| Chloride | Potentiometric Titration with Silver Nitrate | Titration using AgNO3 standard solution and silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate | Barium Sulfate Gravimetric Method | Precipitation as BaSO4 in acidic medium, followed by filtration, drying, and weighing of the insoluble precipitate. |
| Related Substances | HPLC with UV Detection | Separation on reversed-phase column and detection at 205 nm to identify and quantify structurally related impurities (e.g., sorbitol, galactose). |
| Microbial Limits | Membrane Filtration and Plate Count | Filtration of sample solution, transfer to appropriate agar media, incubation, and enumeration of colony-forming units. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volume-based particle size distribution in dry or dispersed state. |

Industrial Dulcitol Procurement FAQ
1. How do you ensure product quality consistency?
We rely on a mature China-based manufacturing system and implement strict batch control and quality inspection for every shipment. Our production process complies with ISO 9001 standards, and a COA is provided for each batch to ensure consistent and reliable quality.
2. Do you offer competitive pricing for bulk orders?
Yes, as a China-based manufacturer and bulk supplier, we provide tiered pricing based on order volume. We support FOB and CIF quotations, as well as L/C payment terms for large transactions to meet international trade requirements.
3. Can you support large-volume or long-term supply?
We have stable production capacity and a well-established supply chain, enabling continuous bulk supply. We support ton-level and container-level orders, as well as long-term cooperation projects.
4. What is your typical lead time?
For in-stock products, shipment can be arranged within 1–3 days. For bulk packaging or customized orders, lead time depends on the specific quantity and production schedule.
5. What documents do you provide?
We can provide complete documentation upon request, including COA, SDS, TDS, and other compliance certificates, meeting industrial procurement and export requirements.
6. Can you customize product specifications or packaging?
Yes, we support customization of parameters such as purity, impurities, residual solvents, and heavy metals. We also offer various bulk packaging options, including 25kg bags, drums, and IBC tanks, suitable for industrial applications and transportation.
7. What shipping options do you support?
We support both FCL (Full Container Load) and LCL (Less than Container Load) shipments, and can flexibly arrange logistics solutions based on order size to meet bulk chemical export needs.
8. Do you provide technical or application support?
Yes, we provide basic application guidance and technical support based on industry experience to help customers optimize product usage.
9. How do you handle compliance and export regulations?
