Description

1. Humectant: Glycerin has hygroscopic properties, meaning it attracts moisture from the air. In pigments, this can help keep the product moist, preventing it from drying out and becoming brittle. This is especially important in cosmetic products like lipsticks or cream-based paints where maintaining moisture is crucial for product performance and user experience.
2. Binder: Glycerin can act as a binder, helping to hold the pigment particles together and adhere them to the surface being painted or applied. This aids in the uniform distribution of pigment and enhances its longevity on the substrate.
3. Plasticizer: In some formulations, glycerin acts as a plasticizer, increasing the flexibility and durability of the pigment. This is particularly beneficial in applications where the pigment needs to withstand bending or stretching without cracking or flaking.
4. Solvent: Glycerin can function as a solvent, especially in water-based pigment formulations. It helps dissolve or disperse the pigment particles, facilitating their incorporation into the base medium and ensuring uniform color distribution.
5. Moisturizing Agent: In cosmetic pigments, glycerin can also provide moisturizing benefits to the skin. Its humectant properties help to retain moisture, keeping the skin hydrated and preventing dryness.
