PEG excipients for tailored dosage forms across a variety of applications
Polyethylene glycols (PEGs) are ethoxylated polymer-solubilizers that are readily soluble in water. CARBOWAX™ SENTRY™ Polyethylene Glycol (PEG) is a pharmaceutical-grade excipient. It is available in a broad range of molecular weights and physical forms (liquid, flake, powder, and granular) allowing formulators to precisely tailor viscosity, melting point, solubility, and release characteristics to meet specific application needs.
From early stage development through commercialization, our PEG excipients help address common formulation challenges such as poor API solubility, inconsistent dissolution, and ingredient compatibility — supporting enhanced API bioavailability while maintaining regulatory compliance.
PEG Active Pharmaceutical Ingredients (APIs) for osmotic laxative and colonic lavage formulations
Our CARBOWAX™ SENTRY™ Polyethylene Glycols (PEGs) 3350 and 4000 (Uninhibited) are active pharmaceutical ingredients (APIs) that are highly water soluble and used in multiple dosage forms.
- Ideal for osmotic laxative formulations for mild and effective treatment to relieve constipation for digestive health.
- Widely used in intestinal lavage formulations to facilitate bowel cleansing prior to medical procedures such as colonoscopies, radiological exams, or gastrointestinal surgery.

A chelating agent and excipient for consumer health applications
Edetate Disodium (EDTA) is a versatile chelating agent that binds trace metal ions that can catalyze oxidation or degradation.
VERSENE™ NA Edetate Disodium (EDTA) is a pharmaceutical grade chelating agent used to enhance the stability and shelf life of drug formulations. It helps protect color, flavor, clarity, and active ingredient performance in liquid, semi solid, and topical formulations. Manufactured to meet U.S. Pharmacopeia (USP) and Food Chemicals Codex (FCC) requirements, VERSENE™ NA EDTA is well suited for pharmaceutical and consumer health applications requiring consistent quality and regulatory compliance.
An excipient for low viscosity formulations
Propylene Glycol (PG) a synthetic, colorless, viscous, and nearly odorless liquid used widely as a solvent, humectant, and preservative. PURAGUARD™ Propylene Glycol (PG) is a high purity, pharmaceutical grade excipient designed for use in formulations requiring exceptional solvency, consistency, and regulatory compliance.
Manufactured to meet USP/EP and Food Chemicals Codex (FCC) standards, it functions as an effective solvent, co solvent, and humectant in liquid and semi solid formulations.
