RESIFA™ SOLESPHERE™ Fine Silica Microspheres for Sunscreen, Skin Care and Cosmetics


RESIFA™ SOLESPHERE™  silica microspheres are natural, environmentally safe additives enhancing the performance of cosmetics, beauty, and skin care products.

SOLESPHERE Characteristics
  • Appearance: dry, fine, white, spherical powder
  • Amorphous
  • Microspherical silica size range (3–20 μm)
  • Porous and nonporous grades
  • Natural material
  • Non-nanoparticle, nonplastic
  • INCI: Silica
  • ECOcert and COSMOS certified
  • Halal and Kosher certified
  • Manufactured in Japan, available worldwide
  • Enhances the feel and texture of formulations
  • Improves spreadability
  • Reduces greasiness and stickiness
  • Provides SPF boost to both organic and inorganic UV actives
  • Absorbs oil and perspiration
  • Provides excellent soft focus or mattifying effect
  • Minimizes pores
  • Suitable in oil-in-water, water-in-oil, and anhydrous formulations
  • Encapsulates oils to form powders and gels
SOLESPHERE Applications
  • Oil and sweat absorption
  • Matte finish
  • Soft focus effect
  • Exfoliation
  • Oil encapsulation
  • Improved feel and texture
  • SPF boosting

Five key SOLESPHERE grades–H-51, H-53, H-121, H-33 and NP-30–can impart the desired mix of performance qualities into a formulation including:

    • UV boost
    • Reduced greasiness, stickiness
    • Oil and perspiration absorption
    • Mattifying/blurring/light-scattering effect
    • Pore minimizing
    • Silky smooth texture (spreadability, glide)
    • Scrub/exfoliant effect (abrasiveness)
    • Leaves skin looking/feeling hydrated and glowing
  • Particle sizes: 3–20 μm
  • Pore diameters up to 11 nm
  • Moisture and oil absorption capacity: 30–400 ml/100 g
  • Excellent heat resistance

  • Sunscreen
  • Tinted moisturizer
  • Skin care
  • Makeup foundation
  • Facial cleanser
  • Exfoliating body scrub
  • Lipstick
  • Mascara

Texture feeling test

Test method: Applied 0.5mg/cm test powder to artificial leather Supplare (made by Idemitsu Techno Fine),
and evaluated texture by KES-SE friction tester (made by Kato tech and sensor: artifical leather Supplare, load 25g).

Soft Focus Effect

Test method: Applied SOLESPHERE samples to the surface of Supplare, and then monitored with a digital microscope (x 25).

SOLESPHERE prevents oily skin and covers up wrinkles.
Optical diffusion (one characteristic of SOLESPHERE) gives these effects.
These effects are proportional to particle size and pore volume.
