Prolonged contact with certain chromium compounds may produce allergic reactions and dermatitis in some individuals (114). The initial response is usually caused by exposure to Cr(VI) compounds, but once the allergy is estabUshed, it is extended to the trivalent compounds (111,115). There is also limited evidence of possible chromium associated occupational asthma, but there is insufficient data to estimate a dose for assumed chromium-induced asthma. Reference 116 provides a summary and discussion of chromium hypersensitivity.

The phenothiazine drugs listed in Table 7 are all capable of cross-reacting with the phenothiazine antihistamines, and all of these compounds are potential photosensitizers (Lewis and Sawicky 1955). Often a photoallergic reaction occurs in combination with the allergic eczematous contact dermatitis. The systemic administration of the phenothiazine drugs shown in Table 7 may produce an eczematous contact dermatitis medicamentosa in individuals sensitized by such topical exposure. Cross-reactions readily take place between these phenothiazines and the related antihistamines (Mitchell and Ongley 1972). 

Most terpenes show low acute oral toxicity and low dermal toxicity. Contact dermatitis is the most common symptom described as a result of exposure to terpenes. Other allergic reactions occur more rarely e.g. allergic rhinitis or allergic bronchial asthma. The most common products with an allergic potential (contact dermatitis) are oils of turpentine. Older turpentine products show higher allergic potential than freshly distilled products. Turpentines have now been replaced by other less toxic petrochemical products.

A 2001 report by the Cosmetic Ingredient Review Expert Panel has described the acute dermal, oral, and inhalational toxicity of the persulfates [346]. The report notes that persulfates can cause both immediate and delayed reactions and that ammonium persulfate is the most frequent alleigen among hair stylists. The persulfates can cause urticaria and both allergic and contact dermatitis, as well as rhinitis, bronchospasm, and syncope [346].

Eye and Skin Contact. Some nickel salts and aqueous solutions of these salts, eg, the sulfate and chloride, may cause a primary irritant reaction of the eye and skin. The most common effect of dermal exposure to nickel is allergic contact dermatitis. Nickel dermatitis may occur in sensitized individuals following close and prolonged contact with nickel-containing solutions or metallic objects such as jewelry, particularly pierced earrings. It is estimated that 8—15% of the female human population and 0.2—2% of the male human population is nickel-sensitized (125). 

Allergic contact dermatitis Skin condition that occurs in response to exposure to sensitizing material. It is characterized by redness, swelling and cracking and, sometimes more severe reactions involving the entire immune system.

Allergic contact dermatitis is a delayed hypersensitivity reaction.30 Upon initial exposure, a substance penetrates the skin, binds to a protein and develops into sensitizing antigens. Subsequent exposures to that substance will then elicit an allergic reaction.25,29,30 Symptoms of allergic contact dermatitis are similar to those of the irritant type, but may take several hours to several days to develop following re-exposure.25,26...
