这个问题的简短回答是：你不能100％肯定！油墨和颜料制造商不需要透露内容。从干颜料中混合自己的墨水的专业人士最有可能知道墨水的成分。但是，这些信息是专有的（商业机密），因此您可能会或可能不会得到问题的答案。它们由悬浮在载体溶液中的颜料组成。与普遍看法相反，颜料通常不是植物染料。今天的颜料主要是金属盐。然而，一些颜料是塑料，也可能有一些植物染料。颜料提供纹身的颜色。载体的目的是对颜料悬浮液进行消毒，使其均匀混合，并且易于施用。本文主要关注颜料和载体分子的组成。然而，纹身有一些重要的健康风险，包括一些涉及的物质的固有毒性和不卫生的做法。要了解有关特定纹身墨水相关风险的更多信息，请查看材料安全数据表（MSDS）中的任何颜料或载体。 MSDS将无法识别与墨水或皮肤内的化学相互作用相关的所有化学反应或风险，但它将提供有关墨水各组分的一些基本信息。颜料和纹身油墨不受美国食品和药物管理局的监管。然而，美国食品和药物管理局正在研究纹身油墨，以确定油墨的化学成分，了解它们在体内的反应和分解，光和磁性如何与油墨反应，以及是否存在短期和长期健康与油墨配方或应用纹身的方法有关的危害。纹身中使用的最古老的颜料来自使用磨碎的矿物质和炭黑。今天的颜料包括原始矿物颜料，现代工业有机颜料，一些植物基颜料和一些塑料颜料。对于许多颜料，过敏反应，瘢痕形成，光毒性反应（即，暴露于光，特别是阳光下的反应）和其他不利影响是可能的。塑料基颜料的颜色非常浓，但很多人都报道了它们的反应。还有颜料在黑暗中发光或响应黑色（紫外线）光。这些颜料是众所周知的风险 – 有些可能是安全的，但其他颜色是放射性的或有毒的。
The short answer to the question is: You can’t be 100% certain! Manufacturers of inks and pigments are not required to reveal the contents. A professional who mixes his or her own inks from dry pigments will be most likely to know the composition of the inks. However, the information is proprietary (trade secrets), so you may or may not get answers to questions. They are composed of pigments that are suspended in a carrier solution. Contrary to popular belief, pigments usually are not vegetable dyes. Today’s pigments primarily are metal salts. However, some pigments are plastics and there are probably some vegetable dyes too. The pigment provides the color of the tattoo. The purpose of the carrier is to disinfect the pigment suspension, keep it evenly mixed, and provide for ease of application. This article is concerned primarily with the composition of the pigment and carrier molecules. However, there are important health risks associated with tattooing, both from the inherent toxicity of some of the substances involved and unhygienic practices. To learn more about the risks associated with a particular tattoo ink, check out the Material Safety Data Sheet (MSDS) for any pigment or carrier. The MSDS won’t be able to identify all chemical reactions or risks associated with chemical interactions within the ink or the skin, but it will give some basic information about each component of the ink. Pigments and tattoo inks are not regulated by the US Food and Drug Administration. However, the Food and Drug Administration is examining tattoo inks to determine the chemical composition of the inks, learn how they react and break down in the body, how light and magnetism react with inks, and whether there are short- and long-term health hazards associated with ink formulations or methods of applying the tattoos. The oldest pigments using in tattoos came from using ground up minerals and carbon black. Today’s pigments include the original mineral pigments, modern industrial organic pigments, a few vegetable-based pigments, and some plastic-based pigments. Allergic reactions, scarring, phototoxic reactions (i.e., reaction from exposure to light, especially sunlight), and other adverse effects are possible with many pigments. The plastic-based pigments are very intensely colored, but many people have reported reactions to them. There are also pigments that glow in the dark or in response to black (ultraviolet) light. These pigments are notoriously risky – some may be safe, but others are radioactive or otherwise toxic.
