Products in Hydrophilic Treatments: Yellow

Gelest Yellow Iron Oxide SR (YIA-SRA) is a yellow powder treated with 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 Yellow Iron Oxide ML (YIA-MLA) is a yellow 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 Yellow Iron Oxide HS (YIA-HSA) is a yellow powder treated with disodium carboxyethyl siliconate. This pigment is used in various color cosmetic formulations. The hydrophilic treatment allows for superior dispersion in water for high loading. This pigment has a higher tinting strength and 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.

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.

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

Coloursphere® WL 10 Yellow HL is an hydrophilic spherical composite material, in which colorants have been encapsulated into a polymer structure. The wetting properties of Colourspheres® WL 10 Yellow HL are excellent due to their small specific surface area. It is typically used in foundations, powders, eyeshadows, and lip applications. Ideal for color changing technology as well.
