New pigments for cosmetic applications have been introduced by EMD Chemicals Inc., the North American Specialty Chemicals affiliate of Merck KGaA, Darmstadt, Germany.
Under the brand name Xirona, Merck KGaA has developed several color travel pigments based on mica and silica for innovative pearlescent pigments. Xirona Golden Sky is represented by a high luster and color travel that changes depending on the angle.
Bi-functional pigments starring Timiron BF-1001 combine the properties of pearl luster pigments with the microbiological stabilization of cosmetic formulations.
The development of the Timiron BF-1001 pigment improves the microbiological stability of cosmetic formulations and multi-purpose skin care activities and provides a safe toxicological profile and easy formulation.
Timiron BF-1001 provides microbiological stabilization. Tests show that cosmetic formulations with 2% Timiron BF-1001 showed very encouraging results. Because Timiron BF-1001 influences the overproduction of microorganisms of the normal skin microflora, it is ideal for skin care products.
Timiron BF-1001 has a particle size range of 5–25 µm. According to the company, it can be easily incorporated into water and oil based systems, and is pH and thermally stable. More info: www.emdchemicals.com.
