Food Grade Propylene Glycol Supplier - Glycols

Food Grade Propylene Glycol is a synthetic, odorless, and colorless liquid used as a food additive and preservative. It is a type of glycol approved by regulatory agencies for safe consumption in various food and beverage products. Commonly employed as a humectant, solvent, or stabilizer, it helps maintain moisture and texture in processed foods.

Size: Typically available in bulk quantities (drums, totes, tankers) or smaller retail containers (1L, 5L, 20L).

Grade: USP (United States Pharmacopeia), FCC (Food Chemicals Codex), or EP (European Pharmacopoeia) compliant for food-grade applications.

Viscosity: ~56 cP at 25°C (77°F), varies slightly with temperature and concentration.

Buoyancy: Slightly denser than water (specific gravity ~1.036 at 25°C), not buoyant in aqueous solutions.

Material: Synthetic organic compound (1,2-propanediol), derived from propylene oxide hydrolysis.

Appearance: Colorless, odorless, slightly viscous liquid.

Freezing Point: -59°C (-74°F), lowers further in water mixtures.

Boiling Point: ~188°C (370°F) at atmospheric pressure.

Solubility: Fully miscible with water, alcohols, and many organic solvents.

pH: Neutral (~6-8 in aqueous solutions).

Flash Point: ~99°C (210°F) (closed cup), non-flammable under normal conditions.
