what are the causes of oil paint dermatitis and what are the causes of oil paint dermatitis

The main cause of oil paint dermatitis is caused by the use of oil paint makeup

First, the cause of the disease

Oil paint consists of pigment, base oil, filler and essence. Any of these ingredients can cause this disease due to quality factors. Neutral Solar Red, Silver Zhu R and Sun Resistant Yellow G are all more sensitizing dyes than prednylazo dyes, and the latter two are nitroazo organic pigments with both light sensing and sensitizing effects. Is the main pathogenic factor causing this disease; Impurities in pigments and lead, essence and base oil in some inorganic pigments (such as iron oxide red) are also pathogenic substances.

In addition to the oil paint itself, priming oil, eyebrow pencil, lipstick, makeup fixing powder, cleansing oil, beard glue (including rosin and dilute ammonia solution), nose putty (for modeling), soap for cleansing, paper quality and cleansing method, outdoor performance, atmospheric humidity and other stimuli have certain influence on skin reaction. New light sources such as halogen tungsten lamp, xenon lamp and dysprosium lamp are used for stage lighting, in which ultraviolet rays are not filtered out, and some pigments and essences in oil paints are mostly organic compounds with light sensitivity, which can often lead to light sensitivity dermatitis or pigmentation under the action of strong lights, especially long wave ultraviolet rays (UVA). Allergic constitution is also an important factor in the onset of disease.

Second, the pathogenesis

Some cases are caused by the primary irritation of pigments or impurities in them, and some cases are caused by the sensitization of organic pigments, or both.
