Introduction of Poly(propylene glycol) (PPG) is a synthetic polymer made from propylene oxide monomers, forming chains with a repeating -(CH₂CH(CH₃)O)- structure. Unlike polyethylene glycol (PEG), its hydrophobic methyl groups reduce water solubility, making it oil-soluble. Available in liquid (low molecular weight, e.g., PPG 400) or waxy solid (high MW, e.g., PPG 4000) forms, it’s used in lubricants, hydraulic fluids, antifoaming agents, and polyurethane production. PPG also acts as an emulsifier in cosmetics and excipient in pharmaceuticals. Generally low in toxicity, it may irritate skin in high concentrations. Avoid overheating, as degradation releases harmful fumes. Ideal for non-aqueous, industrial applications.

PPG also acts as an emulsifier in cosmetics and excipient in pharmaceuticals. Generally low in toxicity, it may irritate skin in high concentrations. Avoid overheating, as degradation releases harmful fumes. Ideal for non-aqueous, industrial applications.
Application of Poly(propylene glycol) (PPG) is a synthetic polymer derived from propylene oxide monomers, forming a chain of repeating -(CH₂CH(CH₃)O)- units. It is a member of the polyether family, closely related to polyethylene glycol (PEG) but with a hydrophobic methyl group that reduces water solubility.
Molecular Weight: Ranges from low (liquid, e.g., PPG 400) to high (waxy solid, e.g., PPG 4000).
Properties:
Hydrophobic: Soluble in organic solvents, oils, and fats.
Low Toxicity: Generally biocompatible and non-irritating.
Thermal Stability: Stable across a wide temperature range.
1. Industrial: Lubricants, hydraulic fluids, antifoaming agents, and polyurethane production (as a polyol).
2. Cosmetics: Moisturizers, emulsifiers, or viscosity modifiers.
3. Pharmaceuticals: Solvent or excipient in topical formulations.
4. Household Products: Detergents, paints, and adhesives.
Considered safe for regulated use, though low-MW forms may cause mild irritation. Avoid high-temperature degradation, which can release toxic fumes.
PPG is distinguished from PEG by its hydrophobic nature and methyl side chains, making it ideal for non-aqueous applications.
