Products in Treated Pigments & Powders: Black

Gelest Black Iron Oxide SR (BIA-SRA) is a black iron oxide powder with the addition of polymethyl silsesquioxane and trimethylsiloxysilicate. The hydroxyl-terminated silsesquioxane network in the coating improves adhesion to skin and hair, making it ideal for use in color cosmetic formulations. This pigment is the best candidate for use in long-wearing and water-resistant makeup.

Gelest Black Iron Oxide ML (BIA-MLA) is a black iron oxide powder treated with dimethicone PEG-3 laurate. This treatment allows for high pigment loading, water repellency, and low viscosity dispersion to maximize color intensity. It is used in various color cosmetic formulations.

Gelest Black Iron Oxide SS (BIA-SSA) is a black iron oxide powder treated with stearyl triethoxysilane. This hydrophobic treatment imparts the excellent wetting properties of the shorter-chain silanes with a more emollient skin feel in powders and dispersed systems. It is a pigment that is used in various color cosmetic formulations.

Gelest BIB-HSA is a black iron oxide powder treated with disodium carboxyethyl siliconate. This pigment is specifically utilized in different color cosmetic formulations. Gelest BIB-HSA offers a higher tinting strength and demonstrates a reduced tendency for color flotation and plate-out.

Aquaspersabil series consists of surface treated pigments with improved dispersibility into the water phase. They can achieve high loads by evenly distributing particles in the medium.

Isopropyl Titanium Triisostearate is a synthetic compound derived from fatty acid. When Iron Oxides are surface treated with Isopropyl Titanium Triisostearate, they display strong color development properties with increased adhesion to the skin. TPT is very reactive to almost all pigments and forms a uniform coating of lipophilic isostearate groups. There are abundant fatty ester groups on the treated surface; therefore, the titanate treated pigments can be easily wetted by and dispersed in organic vehicles, like esters, mineral oils or petrolatum. Oil absorption is substantially reduced, allowing the loading of pigments in the formula to be increased. TPT treated pigments are suitable for liquid foundations, lipsticks, blushes, eye shadows, and sunscreens.

NAI (replacing the original AI, animal-derived treatment) is based on the chemical bonding of Disodium Stearoyl Glutamate to pigments and substrates. The NAI treatment was quickly embraced worldwide because of its unique benefits. The Compatibility of NAI treated pigments in silicone-based systems has been amply demonstrated by their usage in a number of commercially available W/S liquid foundations. NAI and NAID is longwearing and provides a moist, dewy feel while being much easier to disperse in oils and silicones.

ACT is a hybrid surface treatment consisting of vegetable derived amino acid, fatty acid metal soap and silane. Each component provides unique properties that synergistically make the ACT treatment one of the most effective treatments developed to date. (USP 6,482,441.) ACT treatment is applied to pigments and cosmetic substrates using Miyoshi America’s proprietary unique process, which allows for micronization and uniform surface treatment of individual particles

Primrose silica coated pigments are hydrophilic pigments that are ideal for O/W and water-rich systems. The silica coating, with a refractive index similar to human skin, provides a soft focus effect by increasing diffuse reflection. As the trends towards O/W systems continues, Primrose pigments help overcome some of the typical drawbacks of O/W systems such as gritty feel, weak color development, and wet/dry color stability. In turn, chemists will be able to formulate systems with the “fresh” watery feel of O/W systems with the added benefit of soft focus color pigments

MiyoAQUA is a hydrophilic surface treatment based on alginate. This anionic polysaccharide is found naturally in oceans around the world in the cell walls of brown algae and kelp. Inorganic pigments such as iron oxide and pigmentary titanium dioxide surface treated with sodium alginate are highly hydrophilic and provide excellent dispersibility and re-dispersibility into the water phase.

COLOURSPHERES® are spherical composite materials, in which colorants have been encapsulated into a polymer structure. Colourspheres® offer many advantages in comparison with conventional pigments as their structure is very different, and as their surface characteristics have been modified. The wetting properties of Colourspheres® are excellent due to their small specific surface area. They are hydrophilic in surface properties and very easy to disperse allowing time efficient color shading. Coloursphere WL 10 HB are hydrophilic and 10 microns in size.

Coloursphere® WL 40 Black HL is a new generation of cosmetic color composite which is ideal for mascaras. It not only deliver color but it also function as a volumizing agent, thickener and rheology modifier. Coloursphere® WL 40 HL modify the film forming properties of the formulation, improving the wear and performance.

Amerilure AG treatment - Black Iron Oxides is a plant based surface treatment that improves pigment spreadability, luster, gloss, and pigment expression. This hydrophobic treatment offers a luxurious feel with the added benefit of adding antioxidant properties to your formulation.
