Oil Yellow 2 is a synthetic dye that is used primarily in the petroleum and oil industry for various applications. It is known for its yellow color and is used to color or mark different types of oils, fuels, and lubricants. This dye helps in easily identifying and distinguishing between different products and their grades, and it also serves as an indicator for quality control.
Oil Yellow 2 and similar dyes are often added in very small quantities to the products they are used in, as they are highly concentrated and can impart the desired color with just a tiny amount. These dyes are typically soluble in the products they are added to, allowing for even distribution and uniform coloring.
It's worth noting that the use of dyes like Oil Yellow 2 in certain products, especially those intended for consumption or use in sensitive applications, is subject to regulations and guidelines to ensure safety and compliance with industry standards.
