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.

Sympholight “O” Series has high oil dispersibility and provides a film that is highly uniform in color, resulting in a beautiful finish. Since these pigments do not require a high shear process, manufacturing time and resources may be reduced.

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.

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.

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

SA/SAT is the Ultimate Patented Silicone treatment for application to cosmetic pigments and substrates and is composed of Bonded Dimethicone. Bonded Dimethicone treated products have many advantages compared to materials that are either treated with conventional Methyl Hydrogen Polysiloxane (MHPS), or simply mixed with Dimethylpolysiloxane fluid (DMPS). While many other types of treatments may dull pearlescent pigments, SA/SAT Treatment brings out their natural luster and shine.
