A wide range of hollow glass microsphere is manufactured for use in the cosmetic industry. Because of their size and shape, cosmetic hollow glass microspheres offer enhanced sensory properties for a broad range of applications.
Cosmetic hollow glass microspheres are perfectly spherical, completely solid, between 10 and 1000microns in diameter, and can be loaded with up to 40% by weight of pigments and additives. In addition they can be manufactured with a positive or negative surface charge.
Anti-Aging Effect
Microspheres are able to scatter light to diminish the look of fine lines on the skin, creating an effect known as soft focus or optical blurring.
Excellent sphericity and tight particle size of hollow glass microspheres will minimize the appearance of fine lines and wrinkles by both filling them and scattering light, creating a soft focus effect.
Ball-bearing Effect
Sphericity and particle size uniformity are responsible for the ball-bearing effect in creams and lotions, which imparts the finished product with a silky elegant texture, luxury feel, enhanced slip, glide and omnidirectional spreadability providing a “cream to powder” texture. Outstanding roundness also provides lubrication during application. The exceptional smoothness of hollow glass microspheres dramatically enhances the tactile experience of a cosmetic product. This ball-bearing effect promotes better blending on the skin and results in a more natural finish.
Hiding Power
An opaque hollow glass microsphere does not allow any light to pass through which means every single particle has maximum hiding power. Our hollow glass microspheres provide superior coverage with one invisible and feather-light layer – revolutionizing make-up products.
What is opacity and how is opacity measured: When light strikes an interface between two substances, in general some may be reflected, some absorbed, some scattered, and the rest transmitted. An opaque substance transmits very little light, and therefore reflects, scatters, or absorbs most of it. High level of opacity becomes more difficult to achieve for microscopic particles.
Exfoliating Agents
Superior roundness and smoothness of hollow glass microspheres makes them very gentle and effective exfoliating agents to unclog pores and exfoliate dead cells. Round particles has been shown in clinical studies to be less irritating to the skin than irregularly shaped conventional exfoliants with sharp edges, such as apricot kernels and walnut shells.
