Polyglycerol-3 Usage
- PEG-Free & Clean Beauty Formulations: Serving as a 100% natural-origin humectant and structural building block, it is ideal for green, eco-friendly, and PEG-free cosmetic formulations.
- Superior & Long-lasting Moisturization: Due to its larger molecular structure compared to standard glycerin, it provides enhanced water retention and deep hydration without leaving a heavy or sticky residue.
- Dry-Touch & Non-Tacky Skin Feel: Imparts a silky, smooth, and fresh skin feel. This makes it particularly effective for skincare and suncare products designed for hot and humid climates.
- Excellent Compatibility & Co-Emulsification: Demonstrates outstanding compatibility with various non-ionic, anionic, and cationic surfactants, while also acting as an excellent intermediate for creating polyglyceryl esters.
- Skincare Applications: Widely utilized in high-end face creams, hydrating serums, daily lotions, and broad-spectrum sunscreens to improve texture and moisture retention.
- Mild Cleansing Formulations: Ideal for daily micellar water, facial rinses, and mild amino-acid facial cleansers to reduce skin irritation caused by surfactants.
- Hair Care Products: Effectively incorporated into hair styling gels, deep conditioners, and scalp treatments to lock in moisture and improve hair manageability.
