Sorbitol

Sorbitol is a naturally derived polyol widely used in food, cosmetics, pharmaceuticals, and industrial applications, serving as a versatile basic raw material. With a sweet taste approximately 60% that of sucrose, it offers lower calories and non-cariogenic properties, making it an ideal sweetener and humectant for sugar-free foods, functional candies, and solid beverages.

In the cosmetics and personal care industry, sorbitol’s excellent moisturizing properties make it a key ingredient in toothpaste, skin care products, and cosmetics, effectively preventing product cracking while improving texture and stability. In the pharmaceutical field, it acts as a pharmaceutical excipient, commonly used as a tablet filler, oral liquid sweetener, and osmotic laxative, meeting pharmacopoeia standards with high safety.

Industrially, sorbitol is utilized in the synthesis of resins, surfactants, and antifreeze agents, playing a crucial role in chemical manufacturing. Our company provides various specifications including crystalline sorbitol and liquid sorbitol (70% content), featuring high purity, stable quality, complete compliance documents, and reliable supply chain guarantees, to meet the customized demands of food, cosmetics, pharmaceutical, and other industries.

Product Description

Sorbitol, a naturally occurring polyol derived from glucose, is a highly versatile raw material widely used across food, cosmetics, pharmaceuticals, and industrial sectors.

 With a sweet taste approximately 60% that of sucrose, it delivers only 2.6 kcal per gram—less than half the calories of sugar—while being non-cariogenic, making it a preferred choice for sugar-free and low-calorie formulations.

Applications

• Food Industry: As a sugar substitute and humectant, sorbitol is extensively used in sugar-free candies, chewing gum, baked goods, and beverages.

 It prevents crystallization, retains moisture to extend shelf life, and enhances texture without raising blood glucose levels, making it suitable for diabetic-friendly products.

• Cosmetics & Personal Care: Its exceptional moisturizing properties make it a key ingredient in toothpaste, skin creams, lotions, and hair care products.

 It helps maintain skin hydration, prevents product drying, and improves the smoothness and stability of formulations.

• Pharmaceuticals: Sorbitol serves as an excipient in tablets, capsules, and oral liquids, acting as a binder, filler, and sweetener.

 It also functions as an osmotic laxative in oral solutions, providing gentle relief from constipation while meeting strict pharmacopoeial standards.

• Industrial Applications: It is used in the production of polyethers, surfactants, and alkyd resins, as well as a humectant in tobacco and a stabilizer in concrete admixtures.

Usage Guidelines

• Food & Beverages: Typically added at 2–15% depending on the product. For chewing gum and hard candies, higher concentrations (10–30%) are used to achieve sweetness and texture.

• Cosmetics: Incorporated at 1–10% in formulations to provide moisturization, with higher levels (5–15%) in toothpaste and leave-on skincare products.

• Pharmaceuticals: As a laxative, oral solutions are usually administered at 15–30 mL per dose for adults, following medical guidance. As an excipient, it is used at 5–50% in solid dosage forms.

Our company offers both crystalline sorbitol (99% purity) and liquid sorbitol (70% aqueous solution), with stable supply chains and full compliance documentation to meet the rigorous demands of global industries.

Zheng Y, Jiang Y, Yang X, Fu Z, Zhao Z, Li X, et al. Automatic periodical negative air ions reduce postharvest decay and maintain texture and flavor quality of ‘Fuji’ apple during long-term cold storage. Food Chemistry: X. 2024;24:101972. doi:10.1016/j.fochx.2024.101972
The aim of this study was to explore the effect of periodical negative air ions (NAI) on the quality of ‘Fuji’ apple fruit after treatment at 0, 30, 60, and 90 min every 4 weeks. NAI for 60 min decreased weight loss, mitigated decay, and maintained hardness of the apple fruit during the 40 weeks of storage. Treatment of fruits with NAI for 60 min enhanced the apple defense ability against pathogens by maintaining the cell wall integrity and improving the related-enzyme activities as well as accumulation of total phenols and flavonoids. Reverse-phase HPLC and solid-phase microextraction GC–MS analysis showed that NAI treatment for 60 min increased the levels of fructose, sucrose, sorbitol, malic acid and volatiles, such as 2-hexenal, 2-methylbutyl acetate, hexyl acetate, and ethyl butanoate. Taken together, NAI is promising for improving the quality ‘Fuji’ apples during the cold storage.

Surfactants, such as glycolipids, are specialty compounds that can be encountered daily in cleaning agents, pharmaceuticals or even in food. Due to their wide range of applications and, more notably, their presence in hygiene products, the demand is continuously increasing worldwide. The established chemical synthesis of glycolipids presents several disadvantages, such as lack of specificity and selectivity. Moreover, the solubility of polyols, such as sugars or sugar alcohols, in organic solvents is rather low. The enzymatic synthesis of these compounds is, however, possible in nearly water-free media using inexpensive and renewable building blocks. Using lipases, ester formation can be achieved under mild conditions. We propose, herein, a “2-in-1” system that overcomes solubility problems, as a Deep Eutectic System (DES) made of sorbitol and choline chloride replaces either a purely organic or aqueous medium. For the first time, 16 commercially available lipase formulations were compared, and the factors affecting the conversion were investigated to optimize this process, owing to a newly developed High-Performance Liquid Chromatography-Evaporative Light Scattering Detector (HPLC-ELSD) method for quantification. Thus, using 50 g/L of lipase formulation Novozym 435® at 50 °C, the optimized synthesis of sorbitol laurate (SL) allowed to achieve 28% molar conversion of 0.5 M of vinyl laurate to its sugar alcohol monoester when the DES contained 5 wt.% water. After 48h, the de novo synthesized glycolipid was separated from the media by liquid–liquid extraction, purified by flash-chromatography and characterized thoroughly by one- and two-dimensional Nuclear Magnetic Resonance (NMR) experiments combined to Mass Spectrometry (MS). In completion, we provide initial proof of scalability for this process. Using a 2.5 L stirred tank reactor (STR) allowed a batch production reaching 25 g/L in a highly viscous two-phase system.

Why Acetonitrile vs Methanol?
PropertyAcetonitrile (ACN)Methanol (MeOH)
Viscosity (20°C)0.37 cP0.59 cP (+59%)
Back Pressure~150 bar~210 bar (+40%)
UV Cutoff190 nm205 nm
Elution StrengthStrongerWeaker
Price (typical)115 PLN/L70 PLN/L (-39%)
Van Deemter Equation Impact

H = A + B/u + Cu

Higher viscosity (MeOH) → lower optimal flow rate → longer runtime.

Buffer Selection: Why NH₄HCO₃?
  • Volatile: MS-compatible (evaporates without residue)
  • pH range: 6.5–8.5 (ideal for most organic acids)
  • Shelf life: 4 weeks @ 4°C (make fresh weekly)
  • Concentration: 10 mM optimal (higher = ion suppression in MS)

Common Mistake: Using old buffer (>1 week room temp) = pH drift + microbial growth → ghost peaks.

Our Gradient Strategy

  • Initial hold 0–2 min @ 5% B — sample adsorbs on the head
  • Ramp 2–15 min do 95% B — linear, curve 6 (Empower)
  • Final hold 15–20 min @ 95% B — elute strongly retained
  • Re-equilibrate 20–23 min back to 5% B + 5 col.volumes

Column Choice Dilemma

48 godzin stracone na niewidoczne piki

Day 1 — I prepared the sample, injected it, baseline flat. Day 2 — I repeated it 6× with different samples. Nothing. Wave check? Professor: "Take a look at the DAD scan". λ_max = 214 nm, and I had 254 nm set.
Lesson learned (Anna K., studentka 2. rok, PW, 2024-11-15):
ALWAYS run a UV scan of an unknown compound BEFORE the method. 254 nm = aromatics only. 210 nm = universal. Time saved: 2 days of work.

Prep Mistakes That Ruined The Run

What is „system suitability" and do I have to do it?

The teacher said „run an SST". You have no idea what that is. The USP method has a checklist — 4 parameters. Which are critical?

Sample Prep Protocol

  1. Dissolve 10 mg of sample in 10 mL of mobile phase (initial composition)
  2. Sonikuj 5 min → vortex 30 s
  3. Filtruj 0.22 μm PTFE (nie PVDF — adsorbuje!)
  4. Transfer 1 mL do HPLC vial z septum PTFE/silikon
  5. Przechowuj 4°C max 48h

Why Filter 0.22 μm?

Particles >0.22 μm clog the column inlet frit. Pressure rises +50 bar per 100 injections. Column lifetime drops from 2000 to 500 injections. Filter cost: 2 PLN. Column cost: 1800 PLN.
