It is part of the well-known Formula 23 line, created by Mario Barth, founder of Intenze, and represents the darkest tone in the range of pre-mixed greywashes. It comes ready to use, in a generous 300 ml bottle, designed for artists who frequently work in black and grey and want a consistent tone without manual mixing.

How to use
- Shake the bottle well before each use so that the pigments are evenly distributed in the liquid.
- Pour only the necessary amount into disposable caps or cups; do not insert anything directly into the main bottle.
- Being pre-mixed, it is used as is, ready to use, without needing to dilute it with distilled water or mixing solution.
- For intermediate tones, you can combine it with the Light and Medium variants from the same range or with other Intenze inks.
- Work from a dedicated cap throughout the session to avoid contaminating the supply in the bottle.
- At the end, seal the bottle tightly and dispose of the remaining ink in the cap; do not pour it back into the bottle.
- Store the bottle closed, in a cool place and away from direct sunlight.
Tips from us
- Shake each time before use, because pre-mixed greywashes can settle if left unused for a long time.
- Keep the Light and Medium tones from the range handy; together they cover the entire spectrum of shadows and transitions, and Dark gives you depth.
- The great advantage of the pre-mix is consistency: you get the same tone from the first to the last drop, without the variations of manual mixing.
- Write the opening date on the bottle to rotate your stock and use the bottles opened earlier first.
- The 300 ml format offers, according to the description, the best price-to-quantity ratio in the Formula 23 range, suitable for those who work frequently in black and grey.
Warning: The product is marketed as drawing ink; according to the seller's statement, its purpose is drawing, not tattooing, and use for other purposes remains the buyer's responsibility. Being a liquid consumable, observe hygiene: pour into disposable caps, do not reintroduce needles or used ink into the bottle, seal it tightly after each use and store it in a cool place, away from light. Do not share or reuse ink left over from a session.
Frequently asked questions
What is Formula 23 and who created it?▾
Formula 23 is a series of inks created by Mario Barth, founder of Intenze Products and world-renowned tattoo artist. The series includes a pure black and three pre-mixed greywash tones — Light, Medium, and Dark — to cover the entire tonal spectrum, from subtle shadows to deep ones.
What is the difference between Greywash Dark and the other tones in the range?▾
The range includes three tones: Light is the lightest, for highlights and subtle tones; Medium is the intermediate tone, good for transitions; and Dark is the darkest in the greywash range, closest to pure black without being completely opaque, used where you want depth and dense shadows.
Why choose a pre-mixed greywash instead of diluting black manually?▾
For consistency. Every time you manually dilute a black with water or mixing solution, the ratio can vary and you get slightly different tones. A pre-mixed greywash gives you exactly the same tone from the first to the last bottle, which means predictable results and less hassle in each session.
Can I mix it with other Intenze inks?▾
Yes. It combines very well with the Light and Medium tones from the same range to create custom intermediate tones, and in general it can be mixed with other inks from the Intenze range. However, always check the label and product sheet of each product for the manufacturer's recommendations.
How do I store it correctly and how long can a 300 ml bottle last?▾
Shake it before use, work only from disposable caps and seal the bottle tightly after each use, keeping it in a cool place away from light. How long a 300 ml bottle lasts depends a lot on how often and what type of work you do — for someone who works frequently in black and grey it could mean a few months, for someone who alternates styles, longer.
Can I use it for tattoos?▾
On the product page, the seller explicitly states that this ink is intended for drawing, not tattooing, and that using it for any purpose other than the stated one remains the buyer's responsibility. If you want an ink intended for application on skin, choose a product whose datasheet expressly indicates this purpose and always check the label and compliance with current regulations.

Frequently Asked Questions What is Formula 23 and who created it? Formula 23 is an ink series created by Mario Barth, founder of Intenze Products and world-renowned tattoo artist. The number 23 refers to the unique proprietary formulation developed by Barth after years of research. The series includes pure black and three pre-mixed greywash tones (Light, Medium, and Dark) to cover the entire tonal spectrum. What is the difference between Greywash Dark and other tones in the range? The Formula 23 Greywash range includes three tones: Light (lightest, for highlights and subtle tones), Medium (intermediate tone for transitions), and Dark (darkest, for deep shadows). Dark is closest to pure black without being fully opaque, providing depth in realism and portrait work. Why use pre-mixed greywash instead of manually diluting black? Pre-mixed Formula 23 greywash eliminates the variables of manual mixing. Every time you dilute black with water or mixing solution, the ratio can vary, leading to tonal inconsistencies. Formula 23 guarantees the exact same tone from first drop to last, from bottle to bottle, ensuring predictable, professional results in every session. Can I mix Greywash Dark with other Intenze inks? Yes, Formula 23 Greywash Dark can be mixed with any other ink in the Intenze range. It is frequently combined with Medium and Light to create custom intermediate tones. It can also be mixed with colored inks to create desaturated color versions, a popular technique in color realism and colored portraits. How does Formula 23 Greywash Dark heal in the skin? Formula 23 Greywash Dark is renowned for its clean, even healing. The ink maintains its tonality after healing, without turning blue or grey-green as sometimes happens with lower quality inks. Pigments remain stable in the skin long-term, and the tone softens naturally and uniformly over time. How long does a 300ml bottle last? A 300ml bottle lasts depending on work frequency and type. An artist who predominantly works in black and grey may consume one bottle in 2-4 months. For artists who alternate between styles, it can last 4-6 months or more. The 300ml format offers the best price-to-quantity ratio in the Formula 23 range. Is Greywash Dark suitable for whip shading technique? Yes, Formula 23 Greywash Dark is excellent for the whip shading technique due to its balanced consistency. The ink flows uniformly from the needles and allows the artist to create fine gradients through quick, controlled machine movement. The result is smooth shading without visible lines, with fluid transitions between tones. Does the ink need additional dilution before use? No, Formula 23 Greywash Dark is ready to use straight from the bottle, which is its primary advantage. The tone is pre-calibrated by Mario Barth to deliver optimal results without additional dilution. However, artists who prefer a slightly lighter tone can add a small amount of mixing solution or blend it with Greywash Medium. Is Formula 23 Greywash Dark vegan? Yes, Formula 23 Greywash Dark, like all Intenze inks, is vegan-friendly and cruelty-free. The formula contains no animal-derived ingredients and is not tested on animals. Intenze is one of the first major tattoo ink brands to adopt a complete vegan policy across its entire product range. What is the difference between Formula 23 Greywash Dark and Dark Grey Sumi? Both are dark grey tones but with different formulations. Formula 23 Greywash Dark is a pre-mixed greywash based on diluted black, created for perfect consistency. Dark Grey Sumi has a formulation inspired by traditional Japanese ink, with a slightly different texture and behavior in the skin. The choice depends on the artist's personal preference.
