About Emulsifier Ingredients
Emulsifiers allow oil and water to mix stably in a formulation, creating creams and lotions. They work by surrounding oil droplets with molecules that are compatible with both water and oil. Most emulsifiers have low sensitisation rates, but some — particularly PEG-derived emulsifiers — can be problematic for barrier-compromised skin.
Relevance for Sorbitan Stearate: Emulsifiers can disrupt the skin's own lipid barrier through a process called emulsification of skin lipids. For very sensitive or eczema-prone skin, emulsifier-free moisturisers (ointments, oils) are sometimes better tolerated than emulsion-based creams.
