PEG-40 Castor Oil should be considered in the context of its complete formula. The updated cosmetic assessment requires a non-irritating preparation; it does not establish relief of seb derm or tolerance of every product.

Its processed oil and ester components raise a theoretical Malassezia screening question. Research on selected substrates cannot show feeding from this exact mixture or a flare on human skin. PEG-40 Hydrogenated Castor Oil is also a different named ingredient. Consider the finished product and how your skin responds, and ask for advice if irritation persists.
