thermal color changing pigment

KTP-32-BY is a thermochromic powder that transitions from vivid yellow to colorless at 32°C — a body-temperature-adjacent activation point that makes it well-suited for skin-contact applications like cosmetics and nail products. This heat sensitive pigment powder disperses cleanly in most coating and printing systems, and is also available in a BPA Free food grade version for product contact use cases such as cups and utensils. Formulators working in textiles printing, craft art, or specialty inks will find the 1–10μm particle range compatible with a broad range of application methods.

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.
