Pearlescent Radiance, Luminous Smiles: Coloray Empowers a New Aesthetic in Oral Care

From the shimmer of a lipstick to the shifting sheen inside a tube of toothpaste, pearlescent pigments are quietly reshaping how personal care products look and feel. Drawing on titanium-free technology and a multi-layer coating process, Coloray has brought high-purity, high-brilliance pearlescent effects into oral care, giving toothpaste formulas a new kind of visual richness without compromising on safety.

A Product Range Built for Different Design Needs

Coloray's portfolio spans several hundred variants across four core lines: the Chameleon series, the Optical Color-Shift series, the Star Diamond series, and a line of specialty formulations developed specifically for personal care applications.

• The Star Diamond series uses calcium aluminum borosilicate as its base material, delivering exceptional sparkle and gloss.
• The Crystal Chameleon series offers a marked improvement in color vividness and the clarity of its color-shifting transitions.
• The Optical Color-Shift series produces rich, angle-dependent color effects that change as the light hits them.

Particle size, color, and functional blends can all be customized to a brand's specifications, giving premium oral care brands room to build a distinct, differentiated identity.

Engineering Aesthetics Into Everyday Formulas

Behind the color sits a mature, cosmetic-grade research and development system that has turned Coloray's pearlescent pigments into a benchmark solution for toothpaste manufacturers. The pigments hold up well under high temperatures, resist weathering, and disperse evenly, allowing them to stay suspended in a toothpaste base without settling or clumping.

Even at very low dosages, the pigments produce a bright, uniform pearlescent finish, and they do so without interfering with the paste's core cleaning performance. The result is a formula where visual appeal and functional effectiveness reinforce each other rather than competing.

Meeting Regional Regulatory Standards

Regulatory expectations for oral care ingredients vary widely from one market to the next. To address this, Coloray offers separate product lines formulated to meet EU standards and Chinese national standards, giving brands a way to satisfy both safety requirements and performance expectations wherever they operate.

A Technology-Led Approach to Color

From raw material development through to final application, Coloray has kept its focus on research and innovation, working with cosmetics and oral care brands to deliver customized color solutions. With pearlescent pigment technology at the center of its work, the company continues to push the category toward a closer balance of function and aesthetics.
