If you have used highlighters on your skin, you will be concerned about the ingredients of highlighters. Let’s dig into this article to determine whether highlighters are water-based or not.
What Is a Highlighter?
Almost everyone is familiar with highlighters during their academic years. A highlighter is one kind of pen that is used to overlay on top of texts to highlight them. Usually, highlighters come in neon green, neon pink, or neon orange so that they can easily highlight any text in the book.
Highlighting any text will draw attention to a particular line, so our eyes can easily catch it during revisions. Highlighters come in various forms including gel highlighters, dry highlighters, and liquid highlighters.
The consistency of highlighters also depends on what kind of highlighter you use. Most people prefer using liquid highlighters because they are easy to find and easy to use.
Are Highlighters Water Based?
Some highlighters are water-based, but not all. Water-based highlighters are best for classrooms, conference rooms, posters, canvases, etc. People mainly use three types of highlighters. Liquid highlighter is one of them, which is water-based. From students to office employees, everyone prefers using liquid highlighters because of their water-based solution.
Water-based highlighters quickly dry out and do not bleed through paper. The best part is a hack where you can remove liquid highlighter with lemon juice. Simply dip a q-tip into the lemon juice and rub it on the highlighter. Because liquid highlighters are water-based, the lemon juice quickly and easily removes the ink from the text without ruining it.
Liquid highlighters are water-based because they stand out in text and help to draw attention. Other types of highlighters do not have bright neon colors like water-based highlighters. Water-based highlighters contain a substance called fluorescent dye, which makes them brighter and gives them a neon color.
Most manufacturers are now producing water-based highlighters instead of alcohol-based to prevent ink from bleeding through paper. Alcohol-based highlighters fade easily and seep through papers. Moreover, water-based highlighters are non-toxic, give sheer coverage, have bright colors, and dry quickly.

What Is Highlighter Made Of?
Water-based highlighter ink is made with water and a glycol solvent. As you already know, water-based highlighters contain fluorescent dye. The primary pigment, 5% fluorescent dye, is in the highlighter ink to give them a bright neon color.
Other chemicals were later added to give the highlighter different colors. The chemical structure and the dye make the highlighter absorb light in the ultraviolet portion.
Some water-based highlighters also contain a biocide to prevent getting attacked by fungi and bacteria. The bright and different colors of highlighters have distinct chemicals to make them different.
For neon yellow highlighters, the manufacturer uses xanthene and mixes it with coumarine. To achieve the bright neon green color, they combine pyrene-based dyes with Triphenylmethane dyes.
Moreover, blue highlighters also contain triphenylmethane dyes with fluorescent dye. The manufacturer uses rhodamine dyes with triphenylmethane dyes to make pink highlighters. Most highlighters have these chemicals to achieve bright neon colors.

Are Highlighters Water Soluble?
Highlighters are water-soluble because of their chemical name, “fluorescent”. Fluorescent is a water-soluble compound that easily dissolves in water. Note that some highlighters are water-soluble, but not all.
Gel-based highlighters are not water soluble because they do not contain fluorescent. Being water-soluble helps highlighters dissolve in water quickly and you can easily remove their stains from clothes.
However, you cannot wash out highlighter stains totally from the clothing. The stain will fade away because it’s water-soluble but will not go away completely.
