The natural-origin coating enhances skin affinity and sensory performance, giving products a softer, silkier feel with improved comfort during wear—especially important in foundations and daily-use complexion products.
Because the treatment stabilizes pigments within emulsions, MiyoNAT VAA increases formulation stability, reducing settling and separation while improving long-term consistency.

MiyoNAT VAA also provides enhanced wear resistance and water resistance, enabling longer-lasting makeup performance with reduced fading or transfer.
MiyoNAT VAA's COSMOS approval and natural-derived chemistry support clean-beauty, vegan, and sensitive-skin formulations, allowing brands to meet strict regulatory and marketing requirements without compromising technical performance.
Collectively, these benefits make MiyoNAT VAA an advanced, sustainable pigment-treatment technology ideal for premium, high-performance, and natural-oriented cosmetics.

Synthesis of MiyoNAT VAA:
MiyoNAT VAA is obtained through a multi-step process that combines the synthesis of an amino-acid–derived surfactant with a controlled pigment surface-treatment operation.
First, a fatty-acid derivative (for example, a C14 myristic acid derivative) is reacted with an amino acid such as glutamic acid, followed by neutralization (e.g. with sodium hydroxide) to form a mild, anionic surfactant such as sodium myristoyl glutamate.

MiyoNAT VAA is then formulated into an aqueous or hydroalcoholic treatment medium in which the selected inorganic pigments (e.g. titanium dioxide, iron oxides, or mixed oxides) are dispersed under high-shear mixing.
During this treatment step, the amino-acid–based surfactant adsorbs onto the pigment surface via hydrophilic and hydrophobic interactions, forming a thin, uniform organic layer that modifies the pigment’s surface energy, improves wetting behavior, and enhances compatibility with cosmetic binders and the skin.

After sufficient contact time, the treated pigment slurry is subjected to solid–liquid separation, washing (if required), and controlled drying, followed by milling or micronization to achieve the desired particle size distribution.
The result is a free-flowing powder consisting of pigments uniformly coated with the MiyoNAT VAA amino-acid treatment, ready to be incorporated into cosmetic formulations as a high-performance, natural-origin, surface-treated pigment.

History of MiyoNAT VAA:
The history of MiyoNAT VAA is closely tied to the evolution of clean-label and skin-compatible pigment technologies developed by Miyoshi, a global leader in cosmetic surface treatments since the 1970s.
As consumer preferences shifted toward natural-origin cosmetics in the early 2000s—and regulatory frameworks such as COSMOS, Ecocert, and various vegan certifications gained importance—traditional silicone or synthetic-surfactant pigment treatments no longer aligned with market expectations for safety, sustainability, and skin affinity.
In response, Miyoshi began developing next-generation surface treatments derived from renewable, biologically compatible raw materials, focusing particularly on amino-acid chemistry due to its resemblance to natural skin components.

This research culminated in the creation of the MiyoNAT series, with MiyoNAT VAA representing one of the most advanced treatments in the portfolio.
By utilizing amino-acid–based surfactants such as sodium myristoyl glutamate, Miyoshi succeeded in producing a surface treatment that combines high technical performance—excellent dispersibility, long wear, smoother texture—with natural-origin and eco-certified credentials.

Over time, MiyoNAT VAA gained widespread adoption in premium, natural, and sensitive-skin cosmetic lines, especially in complexion products where sensory feel and pigment stability are critical.
Today, MiyoNAT VAA stands as an important milestone in the transition from synthetic to natural, sustainably sourced pigment surface treatments, reflecting both scientific innovation and changing consumer expectations within the global cosmetics industry.
