Gelest, Inc. has launched Ultramarine Pink and Ultramarine Violet (INCIs: Varies) surface-treated pigments, broadening its ultramarine line and enhancing its personal care offerings.
Along with Gelest’s Ultramarine Blue, the surface-treated ultramarine pigments create bright shades to soft pastels in eye makeup and powders. The surface treatments reportedly increase durability, lower oil absorption, improve skin adhesion, enhance water repellency and facilitate dispersion processing in formulations.
According to the company, Gelest selected three hydrophobic surface treatments that deliver multifunctional benefits in eye makeup, where ultramarine pigments see the most use. The ultramarines are available with trimethylsiloxysilicate (SR), stearyl triethoxysilane (SS) and triethoxycaprylylsilane (TC) surface treatments.
The SS treatment is recommended for improved powder feel, longer wear and increased hydrophobicity, and the TC treatment for its economic and hydrophobic attributes.
Ultramarine pigments can also be used for color-correcting off-white skin care, up to 0.10% in a formulation. Additionally, these colorants meet the requirements for vegan, dye-free and lake-free formulations. It is also noted that Ultramarine Pink is UV and heat-stable “red” pigment permitted around eyes.
“We are launching the ultramarines as part of our continuing commitment to the cosmetic pigments market and to enhance our product offering to customers,” said Daria Long, Gelest vice president and general manager of personal care. “We’ve seen a resurgence in pink and violet eyeshadows, so we added these ultramarines to help cosmetic formulators respond to the increased demand.”
Long added, “We recommend the SR treatment for mascaras, eyeliners and especially for powders to prevent sebum breakthrough and decrease creasing on eyelids. The SR treatment contains a film-former that increases water resistance and improves skin adhesion—leading to better wear over time.”
