MAR'VINA®
Base makeup powder product to which NSG glass and silica technology is utilized : MAR'VINA®
Product summary
The major characteristics of SILKYFLAKE® are its transparency and gloss. Because it is borosilicate glass-based, it is durable and has excellent protection against dulling. Natutect™ is an infrared reflective additive that reflects near-infrared rays reducing the risk of damaging subcutaneous tissue, giving the skin a natural skin pigmentation or white color appearance while protecting it. i-NAFLECS® (titanium dioxide encapsulated type), can be used as an alternative material to microplastics, as the silica particles provide a blurring effect that naturally covers pores and blemishes. GLACIA DROPS® is a non-porous glass bead with a soft texture.
MAR'VINA® is the base makeup powder product that utilizes all four of these product groups.
Natural and skin-friendly cosmetic powder
MAR'VINA® is a powder designed for easy use in base makeup cosmetics. Made from carefully selected natural ingredients, these products are gentle and kind to the skin and the environment and have a high natural origin index (ISO 16128).
MAR'VINA® is chemically stable and almost completely free of heavy metals.
1）SILKYFLAKE®
Glass flake with an environmentally friendly, low alkali, low heavy metal, boron-free TA glass, which is made from carefully selected glass materials (TA glass composition: NSG original). As a glass manufacturer, NSG, has developed its own glass flake forming technology to control flake thickness and particle size. This enables to offer a wide range of products.
2）Natutect™
High degree of near-infrared reflection is achieved by controlling thickness of the titanium dioxide coated on glass flake at nano meter level. With such a fine flake thickness and particle size, the coated flake is expected to provide natural toning effect on skin.
3）i-NAFLECS®
Highly dispersed pigments are encapsulated in silica structure. This achieves both a light scattering effect and prevent elution of the pigment.
4）GLACIA DROPS™
True spherical, non-porous glass beads made from NSG's original composition glass. They conform to the skin and provide a natural finish. It is soft to the touch and can be used as a micro-plastic bead substitute.

SILKYFLAKE®
Glass flake with an environmentally friendly, low alkali, low heavy metal, boron-free TA glass, which is made from carefully selected glass materials (TA glass composition: NSG original). As a glass manufacturer, NSG, has developed its own glass flake forming technology to control flake thickness and particle size. This enables to offer a wide range of products. In particular, the 8µm type is extremely thin glass with a sharp particle size distribution. This enables it to have an even finish.

Effects on the skin
SILKYFLAKE® has a platelet structure that adheres well to the skin with longer makeup effect. The base flake is transparent glass, so it does not look dull in contact with oil and sweat.
Discoloration when it attaches to sebum (Assessment method: Blend artificial sebum and sample powder, and apply to a black base Dulling does not occur)
Surface treatment
SILKYFLAKE® has a wide lineup of surface treatments. Having surface treatment with hydrogens dimethicone, lauroyl lysine, sodium myristoyl glutamate, and silica eliminates the "creakiness" of the glass. This creates a tactile texture that makes it ideal for use in base makeup.

Natutect™
High degree of near-infrared reflection is achieved by controlling thickness of the titanium dioxide coated on glass flake at nano meter level. With such a fine flake thickness and particle size, the coated flake is expected to provide natural toning effect on skin.
We also have a lineup of white and skin tone products that can be easily used for base makeup and skin care products.

Effects on the skin
Natutect™ has an expected effect to restrain damage to the skin and reduce rasing skin temperature by reflecting near-infrared.

i-NAFLECS®
Highly dispersed pigments are encapsulated in silica structure. This achieves both a light scattering effect and prevent elution of the pigment. When titanium dioxide is encapsulated, it naturally covers pores and blemishes with its light diffusion effect (so-called soft focus effect).

Effects on the skin
i-NAFLECS® has greater texture than titanium dioxide itself as same smoothness as talc. Due to its soft focus effect resulting from light scattering, the titanium dioxide encapsulated type naturally covers pores and does not show white casting.

GLACIA DROPS®
This is a glass bead with NSG's original TA glass composition that is gentle to the skin and the environment. It is an inorganic spherical powder, yet soft to the touch and can be used as a micro-plastic beads substitute.

Haze value and transparency
GLACIA DROPS® is characterized by its high haze value(soft focus effect) and high transparency. GLACIA DROPS® can be used for both formulations that require soft focus and high transparency.

Eco-friendly product
Upcycled materials have been attracting attention in the cosmetics industry for several years. We challenged to create a value-added material using fraction of glass flake, which had been discarded by sieving in the original process (METASHINE® process). Using glass flake as a raw material also has the advantage of reducing energy use in the process.
