AAM AAM Pigment Chemistry & Ingredient Knowledge 1 — Questions and Answers
Question 1: Which pigment base is most commonly used in professional micropigmentation inks approved for use in the US?
- Iron oxide (Correct answer)
- Azo dye
- Cadmium sulfide
- Titanium nitride
Correct answer: Iron oxide
Iron oxide pigments are the most widely used and accepted base in professional micropigmentation inks due to their stability and biocompatibility.
Question 2: What role does titanium dioxide play in micropigmentation pigments?
- It acts as a carrier fluid
- It lightens and opacifies the pigment (Correct answer)
- It prevents oxidation of iron oxides
- It accelerates pigment retention
Correct answer: It lightens and opacifies the pigment
Titanium dioxide is added to micropigmentation pigments as a white opacifier to lighten shades and increase opacity.
Question 3: Which of the following is a concern associated with organic pigments used in micropigmentation?
- They are too thick to implant
- They may cause allergic reactions or color migration (Correct answer)
- They oxidize immediately on contact with skin
- They cannot be sterilized
Correct answer: They may cause allergic reactions or color migration
Organic pigments have smaller molecules that can migrate and are associated with a higher rate of allergic reactions compared to inorganic pigments.
Question 4: What does 'pigment migration' refer to in micropigmentation?
- Color fading due to sun exposure
- Spreading of pigment beyond the original implantation site (Correct answer)
- Pigment rejection by the immune system
- Changes in pigment hue over time
Correct answer: Spreading of pigment beyond the original implantation site
Pigment migration describes the physical movement of pigment particles away from the intended implantation zone, causing blurring of lines.
Question 5: Which carrier solution component in micropigmentation ink is primarily responsible for maintaining pigment suspension?
- Glycerin (Correct answer)
- Distilled water
- Witch hazel
- Isopropyl alcohol
Correct answer: Glycerin
Glycerin acts as a humectant and viscosity agent in the carrier, keeping pigment particles uniformly suspended throughout the ink.
Question 6: Why should micropigmentation artists avoid pigments containing heavy metals like cadmium or lead?
- They cause rapid fading
- They are prohibited by the FDA and pose serious health risks (Correct answer)
- They increase needle wear
- They are too expensive for professional use
Correct answer: They are prohibited by the FDA and pose serious health risks
Heavy metal-containing pigments are regulated or banned under FDA guidelines because they can cause toxic reactions, systemic absorption, and long-term health complications.
