Sorbitol Powder 25kg Bag Wholesale Price, Food Grade, Cosmetic Grade & USP/BP/EP Pharma Grade E420 Bulk Sweetener Supplier for Confectionery, Chewing Gum and Cosmetic Factories, CAS 50-70-4

Product Overview

Sorbitol Powder (D-Glucitol) is the crystalline polyol — a sugar alcohol — produced by hydrogenating glucose obtained from hydrolysed, refined starch, and then crystallising, drying and sieving the purified liquor. It is the substance listed in China's national food-additive standard GB 1886.187, in the EU food-additive specification E 420 (i), and in the FCC; its additive numbers are INS 420 / E 420 (i) and its CAS number is 50-70-4.

This listing is built around the three supply grades we hold for the same crystal: Food Grade, Cosmetic / Daily-Chemical Grade, and Pharmaceutical Grade. A confectionery plant, a toothpaste producer and an excipient buyer can therefore read one page — each finds the entry that matches its own compliance framework, particle cut and document pack.

All three grades come off the same crystallisation and sieving line and are released against one release specification; what changes between the grades is the market framework the material is documented against, the particle cut chosen for the process, and the documents that travel with the shipment. That is the practical difference a purchasing team is looking for: one supplier, one quality panel, three documented grades.

Sorbitol is about 50–70% as sweet as sucrose (the product specification states roughly 60%), carries roughly one third fewer calories, is very soluble in water, and is not a reducing sugar, so it does not take part in Maillard browning and holds its colour and flavour through heat and acid. In formulation it works as bulk sweetener, humectant, texturizing agent (anti-staling) and chelating agent at the same time, and it is non-cariogenic.

Supply Grades & Grade Matrix

What the three grades are

Note on the pharmaceutical grade: the grade is produced and released to our pharmacopoeia-orientated specification, and the batch is documented with its own Certificate of Analysis. The specific monograph your market requires (USP, BP or EP) should be stated at enquiry stage so that the grade, the test panel and the document pack can be confirmed against it in writing before order.

Grade matrix — one crystal, three compliance frameworks

Which grade do you need?

• You make something that is eaten or drunk→Food Grade. It is the entry documented against the food-additive frameworks (GB 1886.187 / FCC / E 420 (i)) and is the grade used for confectionery, bakery, beverages and frozen desserts.
• You make something applied to the mouth or the skin Cosmetic / Daily-Chemical Grade. Oral care and personal care formulators typically want the finer cuts, where the powder wets quickly and disperses uniformly into a paste or a cream.
• You make a finished medicine or a nutraceutical and your QA file cites a pharmacopoeia Pharmaceutical Grad. State the monograph your market requires and we will confirm the panel and the document pack against it.
• You are not sure→ send us the application, the cut you need and the market you ship to. We will map it to a grade and confirm in writing before you commit to a quantity.

Technical Specification

Product identity

Sorbitol is obtained by catalytic hydrogenation of dextrose / glucose syrups sourced from starch. Depending on the glucose grade used, the fraction that is not D-sorbitol consists of related glycitols such as mannitol and iditol.

Release specification (applies to all three grades)

Two lines in this panel do the most work for a technical buyer, and both are worth pointing out because they are hard to fake downstream of the crystalliser:

• Specific rotation + 4.0° to + 7.0° together with TLC identification A, B, C is what confirms the material is genuine D-glucitol rather than a re-blended polyol mixture.
• Ethylene glycol and diethylene glycol both specified as "absence", alongside melting range ≥ 95 °C, addresses the two incoming-goods complaints that surface most often on powdered polyols.

Market frameworks — the three standards the grades are documented against

How to read this table against section 3.2: our release limits are set tighter than the mandatory national minimum — assay ≥ 98.0% against a ≥ 91.0% requirement, reducing sugar ≤ 0.20% against ≤ 0.3%, total sugar ≤ 1.0% against ≤ 4.4% — and released lots also satisfy the FCC and EU E 420 (i) profiles. In practice one specification and one document set will serve most destination markets.

Particle size — cuts and mesh-to-micron conversion

Reference opening of the sieves we use:

Cuts held in the product specification: 20–60 mesh, 50 mesh, 60–80 mesh, 60–120 mesh. Additional cuts — including 20–40 mesh, 40–60 mesh, 80–120 mesh, 40–100 mesh and 10–20 mesh — are produced to order.

Particle-size release limits, expressed as passing percentage:

Reference sieve profile measured on the 20–60 mesh cut, expressed as cumulative oversize (percentage retained):

How to choose a cut by grade:

Pharmaceutical Grade → 20–60 mesh.

• The coarsest everyday cut: free-flowing, low-dust, and it meters consistently on a filling or blending line.

Food Grade → 20–60 / 60–80 mesh.

• Take the coarse cut where the powder is dry-blended or dosed; take the finer cut where faster wetting shortens the batch.

Cosmetic / Daily-Chemical Grade → 60–80 / 60–120 mesh.

• The fine cuts carry more surface area per gram, so they wet fastest and blend most uniformly into a paste, cream or gel.

Bulk density

Measured on sorbitol powder fractions (static = poured, dynamic = tapped):

Practical working range: about 0.60 – 0.64 g/mL poured and 0.73 – 0.77 g/mL tapped. Use these figures for bag volumes, silo and mixer fill factors, and container payload planning.

Do not confuse bulk density with the solid specific gravity (about 1.47 – 1.49, MSDS 1.489) quoted in section 3.1 — the two are different properties and are used for different calculations.

Typical Certificate of Analysis (three reference batches)

Rather than one batch, we publish three reference batches spanning different cuts and different production runs, so you can see how stable the released quality is from lot to lot. A batch-specific COA is issued for every shipment; the COA in your shipping pack is the governing document.

Reference batch 1 — 20–60 mesh cut, 19 MT

Reference batch 2 — 20–40 mesh cut, 17.5 MT

Reference batch 3 — 20–60 mesh cut, 19.5 MT

What the three batches say together: assay landed in the 99.10 – 99.50% band against a ≥ 98.0% limit; residual moisture stayed between 0.32% and 0.5% against ≤ 1.0%; and the metal figures on reference batch 3 — nickel 0.01 ppm, lead 0.001 ppm — came in two orders of magnitude inside their limits. Read the table as evidence of margin and consistency, not as a promise that every future lot will reproduce these exact numbers; the shipped COA is what governs.

Applications — organised by grade

The crystal is the same in all three grades; what a formulator is really choosing between is the document framework and the particle cut. That is why we ask for the target application and the destination market at enquiry stage — it usually decides the grade and the cut in one step.

Quality Control

Production route. The plant converts corn starch through to finished sorbitol on one continuous line: corn starch slurry → liquefaction → cooling and pH adjustment → protein pre-treatment → saccharification → ion exchange → slurry allotment → decolourising → concentration → separation → decolourising → drying → cooling and crystallisation → sieving / separation → packed product. Because the sugar liquor is purified by ion exchange and decolourising before crystallisation, colour and residual sugar are controlled upstream of the sieve rather than corrected afterwards — which is also why the same release panel can serve the food, cosmetic and pharmaceutical grades.

Release testing on every batch.

• Assay and identity— the sorbitol content is determined by HPLC with refractive-index detection: water as mobile phase, a calcium-form strong-acid cation-exchange column dedicated to sugars and sugar alcohols (300 mm × 7.8 mm reference), column temperature 70–90 °C held within 1 °C, flow 0.5–1.0 mL/min, 20 µL injection, standard and sample both filtered through a 0.45 µm membrane; the external-standard calculation is the referee method. Identity is additionally confirmed by TLC and by specific rotation.
• Water / loss on drying by the Karl Fischer method or the prescribed oven method.
• Reducing sugars, total sugars, residue on ignition, chlorides and sulphates by the prescribed titrimetric and gravimetric methods.
• Metals— nickel, lead, arsenic and heavy metals as Pb.
• Ash insoluble in acid and melting range as physical purity checks.
• Purity-of-origin markers— ethylene glycol and diethylene glycol confirmed absent.
• Microbiology— total plate count, moulds and yeasts, coliforms,E. coli,Salmonella and dead mites.
• Particle size— the released cut is verified on the sieved product.

Microbiological certificate held on file.

Documents and certificates available. A shipment can be supported with the batch Certificate of Analysis, the product specification sheet and the MSDS, together with certificates covering ISO 9001, ISO 22000, HALAL and KOSHER and the manufacturing licence. Tell us at the ordering stage which grade you are buying and which documents your customs broker or QA department needs, and we will put them in the shipping pack.

Packaging & Shipping

All three grades are packed on the same line and to the same format, so a mixed programme — food grade for one market, cosmetic grade for another — travels under one packing standard.

Storage, Handling & Transport Safety

Storage.

• Store in a cool, dry, ventilated area, away from heat, ignition sources, strong oxidising agents, strong odours and direct sunlight. Keep containers tightly closed.
• Sorbitol powder is hygroscopic: re-seal partially used bags promptly and keep them out of humid areas or away from liquid lines and open water.
• Powdered crystalline sorbitol may set firm after prolonged storage; this does not affect its performance — break it up and use it as normal.
• Operate first in, first out; keep bags on pallets, clear of the floor and walls, so air can circulate.

Handling. Normal dust-control practice applies at filling and weighing points. For bulk handling, use splash goggles, gloves, a lab coat and an approved dust respirator.

Safety profile (per the MSDS).

First aid at a glance.

Transport status. This product is not a dangerous good for transport: it is not a DOT-controlled material (U.S.), is not regulated under the IMDG Code, and is not controlled under WHMIS (Canada). Standard containerised sea freight applies, which keeps the shipping documentation straightforward. The MSDS supplied with the shipment governs all transport and handling decisions.

Buyer FAQ

Q1. How do I know which of the three grades to buy? A. Choose by where the product goes: Food Grade for anything eaten or drunk; Cosmetic / Daily-Chemical Grade for oral care and personal care; Pharmaceutical Grade where your file cites a pharmacopoeia and you need the matching document pack. Send the application, the cut and the destination market and we will confirm the grade in writing.

Q2. Is the quality actually different between the grades, or only the paperwork? A. All three grades come off the same line against one release specification (section 3.2), so the purity panel is identical. What differs is the framework the material is documented against, the particle cut we recommend and the documents that ship with it. Where a market requires tighter grade-specific limits — for example a microbial limit — tell us the monograph or the specification and we will confirm against it.

Q3. Can you supply to a pharmacopoeia monograph (USP / BP / EP)? A. The Pharmaceutical Grade is produced and released to our pharmacopoeia-orientated specification. State the monograph your market requires at enquiry stage; we will confirm the matching grade, the test panel and the document pack in writing before order.

Q4. What is the purity? A. The release limit is assay ≥ 98.0%; our three published reference batches tested at 99.50%, 99.50% and 99.10%. Identity is confirmed by identification A, B, C, TLC and specific rotation.

Q5. How much moisture does it carry? A. Loss on drying is limited to ≤ 1.0%; the reference batches measured 0.32% and 0.5%.

Q6. How low are the sugars? A. Reducing sugars are limited to ≤ 0.20% and total sugars to ≤ 1.0% on release; reference batches measured 0.05%, 0.09% and 0.10% reducing sugar and 0.15%, 0.20% and 0.2% total sugar.

Q7. How do I know the material is genuine D-glucitol and not a blend? A. Two specification lines answer this directly: specific rotation + 4.0° to + 7.0° with TLC identification A, B, C, plus ethylene glycol and diethylene glycol both specified as absolute absence and melting range ≥ 95 °C. All were confirmed on the reference batches.

Q8. Which particle size should I order? A. In practice: 20–60 mesh for dry blending, dosing and pharmaceutical handling; 60–80 / 60–120 mesh where fast wetting and uniform dispersion into a paste or cream matter. Other cuts — including 20–40, 40–60, 80–120, 40–100 and 10–20 mesh — are produced to order.

Q9. Will it brown when I heat or bake it? A. No. Sorbitol is not a reducing sugar, so it does not take part in Maillard browning, and it tolerates a wide temperature range.

Q10. Does it cake or dust? A. Sorbitol is hygroscopic, so keep the bag sealed; a coarse cut is less prone to compaction than a fine powder, and a fine cut carries a smaller airborne-dust load than a flour-grade material. The powder may set firm in storage, which does not affect performance.

Q11. Is it suitable for sugar-free and oral-care products? A. It is a sugar alcohol used as a bulk sweetener in sugar-free and reduced-calorie formulations, and it is non-cariogenic, which is why oral-care formulators use it. Whether a finished product may carry a "sugar-free" claim depends on your local labelling rules — we supply the data, you make the claim.

Q12. How is it packed? A. Standard packing is 25 kg net per bag, white PP woven outer bag with a food-grade PE inner liner (unprinted). Alternative bag types, bag weights, palletising and private-label printing can be arranged to order.

Q13. What documents come with the goods? A. Standard: the batch Certificate of Analysis and the product specification sheet, with the MSDS on request. Plant-level documents available include ISO 9001, ISO 22000, HALAL, KOSHER and the manufacturing licence. For the Pharmaceutical Grade, tell us the monograph your market cites so the document pack matches it.

Q14. Is it a dangerous good for shipping? A. No. It is not DOT-controlled, not regulated under the IMDG Code and not WHMIS-controlled; standard containerised sea freight applies.

Q15. What are the MOQ, lead time, price and payment terms? A. Send the grade, the cut, the required quantity, the destination port and the packing preference, and we will confirm MOQ, lead time, price and payment terms for that specific shipment.
