What Is Polyethylene Glycol 1000?
Polyethylene Glycol 1000 is a synthetic polyether produced by polymerization of ethylene oxide to an average molecular weight of approximately 1000 g/mol. It is a white to off-white, soft waxy solid at room temperature with a melting point of approximately 37 to 40°C. This melting point is close to body temperature, giving PEG 1000 a unique combination of room-temperature structural integrity and body-temperature softening that is directly relevant to its pharmaceutical applications.

PEG 1000 as a Pharmaceutical Excipient: Key Applications
1. Suppository Base
Suppository formulation is one of the most established and critical pharmaceutical applications of PEG 1000. Suppository bases must meet demanding performance requirements: they must be solid and handleable at room temperature, melt or dissolve in rectal or vaginal fluids at body temperature (37°C), and release the active pharmaceutical ingredient (API) reliably for absorption.
Why PEG 1000 is used in suppository bases:
PEG 1000 is typically blended with higher molecular weight PEG grades such as PEG 4000 or PEG 6000 to achieve a suppository base with the correct melting range and consistency. Because PEG-based suppositories dissolve in rectal fluids rather than melting at body temperature (unlike fatty acid bases such as cocoa butter), they release the API by dissolution. This dissolution-based release mechanism is more predictable and temperature-stable during storage and distribution.
|
PEG Suppository Base Blend |
Characteristics |
|
PEG 1000 (high proportion) + PEG 4000 |
Softer base; faster dissolution; suitable for APIs requiring rapid release |
|
PEG 1000 (low proportion) + PEG 4000 |
Firmer base; slower dissolution; suitable for sustained effect |
|
PEG 1000 + PEG 6000 blend |
Harder base; suitable for tropical climate storage |
PEG-based suppository bases are preferred in tropical and warm climates because their dissolution-based release mechanism is unaffected by storage temperatures that would cause fatty acid bases to soften unacceptably.
2. Tablet Lubricant
As a water-soluble lubricant in tablet manufacturing, PEG 1000 (in solid or melt form) reduces friction between tablet granules and the die wall during compression, preventing tablet sticking and ejection problems.
Advantages of PEG 1000 as a tablet lubricant:
- Water-soluble: Unlike magnesium stearate, PEG 1000 does not create a hydrophobic film on granule surfaces. Water-soluble lubricants do not retard tablet disintegration or dissolution, which is critical for immediate-release tablet formulations.
- Melt lubrication: PEG 1000 can be applied as a melt lubricant by heating it above its melting point and spraying or blending it onto granules before compression.
- Compatible with most APIs and excipients: PEG 1000 does not react with most pharmaceutical ingredients, making it broadly compatible across tablet formulation platforms
- Acceptable for regulated markets: Listed in the FDA Inactive Ingredient Database and pharmacopoeia monographs for tablet lubricant use
Typical usage level in tablet formulation: 1% to 5%
3. Ointment Base
In topical pharmaceutical preparations, PEG 1000 is used in combination with other PEG grades to formulate official PEG ointment bases. The classic PEG ointment base formula blends a liquid PEG grade (PEG 400) with a solid grade (PEG 1000 or PEG 3350) to achieve the desired consistency.
Advantages of PEG ointment bases in pharmaceutical topical products:
- Water-washable: PEG ointment bases can be removed from skin with water, unlike petrolatum or lanolin bases
- Non-staining: Do not stain clothing or wound dressings
- Compatible with aqueous wound exudate: Suitable for wound care and burns topical products
- Good API release: Water miscibility facilitates API release from the base
- Stable: Longer shelf life than fatty acid-based ointments in some climates
PEG 1000 ointment base formulations are used in dermatological antibiotics, antifungal topical preparations, wound care products, and hemorrhoid preparations.
4. Semi-Solid Capsule Fill (Hard Capsule Melt Fill)
In hard gelatin capsule melt-fill technology, PEG 1000 serves as a semi-solid carrier for APIs. The API is dissolved or dispersed in molten PEG 1000 at temperatures above 40°C, filled into hard capsule shells at the melt stage, and allowed to solidify at room temperature.
Why PEG 1000 is used in melt-fill capsules:
- Melts cleanly above 37 to 40°C, allowing liquid fill at low process temperatures
- Dissolves or disperses many poorly water-soluble APIs effectively
- Forms a stable, homogeneous solid dispersion on cooling
- The melt-fill process can improve the apparent solubility and bioavailability of poorly soluble APIs by maintaining them in an amorphous or finely dispersed state in the PEG matrix.
5. Film Coating Plasticizer
For aqueous coatings of films for pellets and tablets, PEG 1000 is used as a plasticizer in polymer solutions (typically HPMC, hydroxypropylmethylcellulose HPMC or polyvinyl alcohol (PVA).
The plasticizer decreases the temperature of the glass transition (Tg) for the coating polymer. This makes the film more flexible and less susceptible to breaking during Tumbling and coating of the pan or tablet handling, as well as downstream processing procedures. PEG 1000's form is solid. It permits precise weighing and disintegrates completely inside the aqueous coating process.
Pharmaceutical Grade Requirements for PEG 1000
When sourcing PEG 1000 for pharmaceutical manufacturing, the grade and purity must conform to the applicable pharmacopoeia monograph; the USP-NF, BP, and EP each maintain specific monographs for PEG 1000 that define acceptable limits for:
