Пентиленгликоль

Внешний вид и аромат

Pentylene Glycol is supplied as a clear, colorless liquid. It is generally odorless or may have a faintly sweet odor. Buyers should confirm appearance, odor, and batch-specific quality requirements against the Certificate of Analysis before commercial use.

Срок годности

When stored in unopened and intact packaging under recommended conditions, Pentylene Glycol has a shelf life of 24 months. Storage conditions should be maintained throughout warehousing and transportation to help preserve product quality.

Content by HPLC

Pentylene Glycol has a purity of at least 99.0% by HPLC. A batch-specific Certificate of Analysis can be requested before shipment for quality review and supplier qualification.

Recommended Formulation Use

Pentylene Glycol can be evaluated for cosmetic, personal-care, pharmaceutical, and selected industrial applications.

• Skin Care Products: Typical starting evaluation levels are 1.0% to 5.0%, depending on formula type, moisture-retention requirements, product texture, and stability targets.
• Shampoos and Conditioners: Typical starting evaluation levels are 1.0% to 3.0%, depending on the surfactant system, product viscosity, and compatibility requirements.
• Body Lotions and Creams: Typical starting evaluation levels are 2.0% to 5.0%, depending on emulsion design, skin-feel targets, and preservation-system requirements.
• Pharmaceutical Formulations: Pentylene Glycol may be evaluated as a solvent or stabilizer in oral, semi-solid, and topical formulations where compatible with the active ingredient and dosage form.
• Preservation Systems: Pentylene Glycol can be assessed as part of a broader preservation strategy, subject to formulation testing and microbiological challenge testing.

Final use levels should be determined by qualified formulators after stability, compatibility, safety, and regulatory assessment.
