ABSTRACT
In this chapter, non-fragrance ingredients of cosmetics, that have caused immediate-type reactions, either from their presence in cosmetics or in other products, are presented. Possible symptoms (single or in combination) of such reactions include localized erythema, itching or tingling, localized urticaria, angioedema, generalized urticaria, respiratory symptoms (wheezing, dyspnea, asthma, rhinitis, nasal discharge), cardiac problems (hypotension, bradycardia, ventricular fibrillation or cardiac arrest), gastrointestinal symptoms (abdominal pain, diarrhea, nausea, vomiting) or even anaphylactic shock, which may be life-threatening in some patients and proved fatal in exceptional cases.
