Pharmaceutical
Pharma-grade excipients — solubilizers, binders and emulsifiers for formulations.
Why pharmaceutical formulations need excipients
Pharmaceutical formulations depend on excipients that do more than fill — solubilizers, emulsifiers, binders and carriers that make actives bioavailable, stable and manufacturable. The choice of excipient affects dissolution, shelf life and processability, so pharma buyers qualify raw materials rigorously.
The grades we supply for pharmaceutical work — PEG-4000 and Tween-80 — are well-known excipient chemistries used in oral, topical and liquid systems. Confirm your target market and pharmacopoeia requirements with our team; documentation is provided case by case.
- Polyethylene glycol 4000 for binders, ointment bases and solubility enhancement
- Polysorbate 80 for solubilization and emulsification
- Excipients evaluated against your pharmacopoeia and formulation
Pharma qualification is documentation-heavy: buyers need data sheets, certificates and regulatory support for each market. We provide documentation case by case and do not claim certifications we do not hold, so pharmaceutical customers can qualify us against their own requirements without surprises.

What we supply
Products from our catalogue used in pharmaceutical formulation work:
Tween-80 (Polysorbate 80)
Nonionic surfactant (polysorbate 80). Functions as an oil-in-water (O/W) emulsifier and solubilizer for cosmetic, pharmaceutical and food systems.
Tween-80
Application examples
- Ointment and cream bases — PEG-4000 contributes structure and water solubility to topical bases.
- Solubilization — Tween-80 (polysorbate 80) solubilizes poorly soluble actives and oils into aqueous systems.
- Tablet and capsule processing — PEG grades act as binders and lubricants in solid-dose manufacturing.
- Oral solutions — polysorbate emulsification supports uniform dispersion of actives in liquid dosage forms.
- Suppository and topical bases — PEG blends provide structure, melting behaviour and water compatibility in specialty bases.
- Film coating of tablets — PEG-based systems improve gloss, moisture protection and dissolution control in solid-dose production.
