temperature changing pigment

KTP-31-PBF is a rose red thermochromic pigment powder that transitions to colorless at 31°C — a body-temperature-proximate activation point well-suited for skin-contact and food-contact applications. Certified BPA Free, this heat reactive pigment is formulated for cosmetics, nail systems, and food-contact printing where safety compliance is non-negotiable. It performs equally well in textile printing and craft applications where a clean, reversible color-fade effect is the design intent.

KTP-17-MG is a thermochromic powder that transitions from malachite green to fully colorless at 17°C — a low activation threshold that makes it effective for skin-contact, ambient-response, and cool-environment applications. As a heat reactive pigment, it integrates cleanly into printing, coating, and cosmetic systems where a sharp, reversible color reveal is the intended effect. Typical end-uses include nail formulations, textile printing, and craft coatings.

Thermochromic pigments respond to temperature shifts by altering their visual appearance — either transitioning to colorless or shifting between distinct color states. In cosmetic formulations, this creates interactive products that react to skin temperature, ambient heat, or touch. For formulators working with lip products, nail lacquers, eyeshadows, or novelty cosmetics, these pigments offer a functional alternative to static color.
