Our take
Is Disteareth-75 IPDI a Good Ingredient?
Good: a reliable PEG-based emulsifier that consistently stabilizes oil-in-water systems and improves texture, with a generally low irritation profile at typical cosmetic levels. It offers formulation performance rather than skin benefits, which is why it rates Good rather than Great.
