由 "Mic" post 係 CMC 處 copy 過來的... Mr. Color的物料安全資料表(Material Safety Data Sheet)
模型油吸得多對身體冇益，呢樣野眾所周知。但到底有幾冇益呢？模型油裡頭又有d咩有毒物質呢？
早陣子我分別向幾個模型油品牌索取佢地既MSDS，結果除左被田宮以「油漆成份屬商業秘密」為由婉拒外，其他廠商都好合作咁俾左資料我。作為一個化學白痴既我，當然唔識睇啦，不過就裡頭一d主要成份，我都上網查過佢地既毒性，即管同大家分享一下，希望大家有個參考。
首先係最多人用既Mr. Color，以下係佢比較主要既成份同我就呢d物質抄返黎既一d資訊：
二氧化鈦 Titanium Dioxide (17.28%)
Titanium dioxide has recently been classified by the International Agency for Research on Cancer (IARC) as an IARC Group 2B carcinogen ''possibly carcinogen to humans''. Titanium dioxide accounts for 70% of the total production volume of pigments worldwide. It is widely used to provide whiteness and opacity to products such as paints, plastics, papers, inks, foods, and toothpastes. It is also used in cosmetic and skin care products, and it is present in almost every sunblock, where it helps protect the skin from ultraviolet light.
甲基異丁酮Methyl iso-butyl ketone (19.44%)
Acute (short-term) exposure to methyl isobutyl ketone may irritate the eyes and mucous membranes, and cause weakness, headache, nausea, lightheadedness, vomiting, dizziness, incoordination, narcosis in humans. Chronic (long-term) occupational exposure to methyl isobutyl ketone has been observed to cause nausea, headache, burning in the eyes, weakness, insomnia, intestinal pain, and slight enlargement of the liver in humans. Lethargy and kidney and liver effects have been observed in rats and mice chronically exposed by gavage (experimentally placing the chemical in the stomach), ingestion, and inhalation. EPA has classified methyl isobutyl ketone as a Group D, not classifiable as to human carcinogenicity.
異丁醇iso-butanol (12.5%)
Inhalation may cause irritation to the respiratory tract and may cause anemia and liver damage. Causes irritation to eyes, skin, gastrointestinal tract and mucous membranes. Conditions aggravated/target organs: Persons with pre-existing eye, skin and respiratory conditions may be more susceptible.
當然以一個業餘模型人吸入既劑量，未必真係會引致上面既問題，不過為安全計，請大家都係做足安全措施好。
