The silica used in MiyoHAZE SM typically has an index of refraction and is closer to that of human skin at 1.46. In personal care formulations, MiyoHAZE SM results in diffuse reflection/transmission of incident light and provides an acute, optical effect of reducing skin imperfections such as large pores and wrinkles.

A proper dispersion is essential for optimal performance of a sunscreen product. It provides better UV protection, improves stability, and reduced whitening improves cosmetic appeal. Titanium dioxide is an effective UV absorber, and its physical and chemical stability differentiates this filter from organic UV absorbers. To improve dispersion in formulas and performances, TiO2 is available treated with various inorganic and organic compounds. Many dispersions can be difficult to work with due to their lack of flow in cosmetic oils and their requirement to be dispersed using a surfactant or dispersant

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.

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.

MiyoHAZE BB-ALT is a newly developed synthetic microbead powder consisting of Aluminum Calcium Sodium Silicate surface treated with Triethoxycaprylylsilane. It provides a high soft focus effect to cover pores and wrinkles effectively even when wetted with oils. It provides good wet and dry haze, high total transmittance, and smooth and uniform spreadability onto the skin, allowing for natural coverage when used in cosmetic formulations. MiyoHAZE BB-ALT meets customer demand for natural look while covering skin imperfections.

Triethoxycaprylylsilane treated pigments offer benefits of both silicone and hydrocarbon treatments with the presence of hydrocarbon chain on silicone backbone. Alkyl Silane treated pigments have excellent dispersibility in various oils including; esters, mineral oils, plant oils and silicone fluids. The lipophilic caprylyl group offers excellent hydrophobicity and unique creamy/adhesive feel in powders and liquid formulations. It allows for good coverage onto the skin due to its affinity with sebum.

Mica is a natural mineral used as a cosmetic powder that aids in the spreading of cosmetics. Due to its reflective properties, mica enhances a softer and more youthful look when used in cosmetic formulations. In its native form, Mica resembles metal in thin rock sheets or flakes, with an iridescent, pearly luster. While Mica typically displays a gray to brown color characteristic, Miyoshi’s Mica CM-10 exhibits a white color when dry, and off-white when wet with mineral oil. Mica Miyoshi is able to offer Mica CM-10*, both untreated and surface treated, with a variety of our innovative surface treatments including our patented, silky-smooth Dimethicone (SA) treatment for a luxurious feel.

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.

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.

The MiyoSHADE line of inorganic Titanium Dioxide powder sunscreens provide some of the most effective and safest protection while providing long lasting and water resistant properties. These sunscreens are registered with the Food and Drug Administration (FDA) in the United States and also comply with the Annex VI of Cosmetic Regulation 1223/2009 opinion in the European Union.
