FAQ (Frequently Asked Questions)
1. What is Polysorbate 80?
Polysorbate 80 is a non-ionic surfactant and emulsifier derived from sorbitol (sugar alcohol) and oleic acid (usually from vegetable oils). It is used in personal care products to solubilize oils, disperse active ingredients, and stabilize emulsions, especially in formulations containing oil and water phases.
2. What is the INCI name and CAS number of Polysorbate 80?
CAS Number: 9005-65-6
INCI Name: Polysorbate 80
3. What are the main benefits of using Polysorbate 80 in cosmetics and personal care products?
Excellent solubilizer for essential oils, fragrances, and actives
Stabilizes oil-in-water emulsions
Acts as a dispersing agent for pigments and other particles
Non-irritating and suitable for a wide range of skin types
Improves product consistency and spreadability
4. In which types of products is Polysorbate 80 commonly used?
Polysorbate 80 is versatile and found in:
Serums and facial mists
Lotions and creams
Makeup removers and micellar waters
Hair conditioners and treatments
Bath oils and oil-based cleansers
Color cosmetics and sunscreens
5. Is Polysorbate 80 safe for sensitive skin and daily use?
Yes, Polysorbate 80 is widely recognized as safe and non-sensitizing when used within recommended concentrations. It is suitable for daily-use products and is often included in formulations for sensitive or allergy-prone skin.
6. What is the recommended usage level of Polysorbate 80?
Typical usage ranges from 0.1% to 5%, depending on its function in the formula (solubilizer, emulsifier, or dispersant).
7. Is Polysorbate 80 natural or synthetic?
Polysorbate 80 is semi-synthetic. While it is derived from natural sources (sorbitol and vegetable fatty acids), it undergoes chemical modification to enhance its emulsifying performance. It is accepted in many clean and sustainable beauty formulations, though not considered organic.
8. Is Polysorbate 80 biodegradable and environmentally friendly?
Polysorbate 80 is biodegradable and generally regarded as safe for the environment. However, formulators aiming for zero synthetic ingredients or organic certifications may opt for more naturally derived emulsifiers.
