Application Fields

Food Manufacturing Industry	Alcoholic Beverages: Glycerin is used as a flavor modifier, sweetener, and bitterness-masking agent in alcoholic beverages. Appropriate addition can enhance aroma, sweetness, and body. Meat Products: Used as a humectant in dried meat, sausages, and cured meat products to maintain softness and improve tenderness.
Beverage Industry	Juices and Soft Drinks: Applied in fruit juices and fruit vinegar beverages to effectively reduce bitterness and astringency, enhance body and aroma, improve appearance, and deliver a balanced sweet-and-sour taste.
Baking Industry	Pastries and Cakes: Used in bread and cakes as a moisture-retaining agent. Its strong hygroscopicity helps maintain softness and extend shelf life.
Pharmaceutical Industry	Glycerin is used in various pharmaceutical formulations, including oral, ophthalmic, parenteral, and topical preparations.
Personal Care Industry	Moisturizing Agent: Glycerin absorbs moisture from the air to hydrate the skin and locks in skin moisture to prevent water loss. Skin Repair: Helps support skin recovery, reduces the occurrence of irritant dermatitis, and assists in restoring the skin’s natural barrier function.

Packaging

IBC tanks, drums, and tank trucks.

Storage Conditions

Glycerin is hygroscopic and should be stored in tightly sealed containers such as glass, plastic, or stainless steel containers, and kept in a cool, dry place.

Glycerin Compliance

Our glycerin products comply with Chinese National Standards, Light Industry Standards, Industrial Standards, as well as international standards such as USP and EP.

Toxicity:

The medicinal actions of glycerol are due to osmotic action; orally, 75 ml of glycerol is equivalent to 996 mosmol. Large intravenous doses of glycerol can cause hemolysis, hemoglobinuria, and subsequent renal failure. The osmotic effect of glycerol can lead to tissue dehydration and decreased cerebrospinal fluid pressure. Certain medical conditions such as cardiac, renal, or liver disease and/or diabetes mellitus may be exacerbated by shifts in body water as a result of oral, intravenous, or rectal (suppositories) administration of glycerol. No systemic effects have been reported following the application of large amounts of glycerol to the skin.

Henrys Law Constant:

4.7×106mol/(m3Pa) at 25℃, Burkholder et al. (2019)

Air and Water Reactions:

Hygroscopic. Water soluble.

Reactivity Profile:

GLYCERINE is incompatible with strong oxidizers. Glycerol is also incompatible with hydrogen peroxide, potassium permanganate, nitric acid + sulfuric acid, perchloric acid + lead oxide, acetic anhydride, aniline + nitrobenzene, Ca(OCl)2, CrO3, F2 + PbO, KMnO4, K2O2, AgClO4 and NaH. A mixture with chlorine explodes if heated to 158-176° F. Glycerol reacts with acetic acid, potassium peroxide, sodium peroxide, hydrochloric acid, (HClO4 + PbO) and Na2O2. Contact with potassium chlorate may be explosive. Glycerol also reacts with ethylene oxide, perchloric acid, nitric acid + hydrofluoric acid and phosphorus triiodide.

Autoignition Temperature:

698 °F

Critical Temperature & Pressure:

Store at +5°C to +30°C.

Handling and Storage

Precautions for safe handling

NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

Separated from strong oxidants.Glycerol should preferably be stored at 40 - 60 deg C under nitrogen blanketing. It is not corrosive and presents little risk of ignition because of its high flash point. Highly concentrated glycerol does not corrode steel, but storage tanks of carbon steel must be protected by surface coating to prevent rusting by residual moisture. Glycerol is therefore usually stored in tanks of stainless steel or aluminum.
