Cosmetics and Personal Care Sector
– Serves as a humectant, often paired with glycerin and hyaluronic acid.
– Aids in dissolving water-insoluble ingredients in formulations, such as certain actives (vitamins), plant extracts, or fragrances, enhancing product stability.
– Can synergize with other preservatives (e.g., phenoxyethanol) to reduce preservative dosage, making it suitable for sensitive skin products.
Common products: lotions, creams, serums, toners, masks, children’s skincare, etc.
Industrial Applications
– Serves as a solvent or film-forming aid in paints and inks, improving paint film flexibility and adhesion while regulating product viscosity.
– Added as a co-solvent in industrial cleaners for precision instruments or metal surface cleaning.
As a pharmaceutical excipient, it serves as a solubilizer and stabilizer in formulations such as oral liquids and ointments.
