Polyglyceryl-4 Isostearate
Ingredient Info
Polyglyceryl-4 Isostearate is an emulsifier that helps blend oil and water-based ingredients together in skincare formulas. It's particularly useful in sunscreen and moisturizer products to create stable, smooth textures.
Benefits
- Stabilizes emulsions for longer shelf life
- Helps control how quickly active ingredients like sunscreens are absorbed into skin
- Creates smooth, even product texture
Science: Research shows this emulsifier can modulate skin permeation of sunscreen actives, potentially reducing unwanted absorption when used in formulations—a desirable safety feature. It has an established safety profile in cosmetic use.
