nanocrystals of difficultly soluble organic substances or organic substances with a high melting point, such as boswellia acids (frankincense), phytosterines, flavonoids, and their glycosides (for instance, rutin, as well as ceramides).Solid nanoparticles, except for organic nanocrystals, mostly either non-degradable or rather persistent to degradation. Their degradability depends on the individual components that were processed. Furthermore, there is a distinction made between solid and liquid nanoparticles.

In skin care, there are two types of nanoparticles used in cosmetic formulations: non-biodegradable and biodegradable. Still, in the world of cosmetics (and other fields), nanoparticles also open a world of possibilities for the benefit of humankind. It is easy to see why nanoparticles have a bad reputation. These components are non-biodegradable nanoparticles: diesel dust (lungs), coal dust (lungs), asbestos particles (lungs), anti-cancer nanoparticles (injected medical iron particles – liver), and other insoluble powder-like technical nanoparticles (lungs). Some can have adverse effects on the human body.
smoke and soot from fires (campfire, chimney, and forest fires).Nanoparticles have been around for billions of years, and individuals are exposed without thinking about it. The use of nanotechnology has stretched across various streams of science, from electronics, optics, and magnetics to medicine, and has found applications in the field of cosmetics.

In my book, Make it Up, feel free to replace calcium carbonate with silica microspheres in any recipe for a better end result.Nanotechnology is the science of manipulating atoms and molecules in the nanoscale – 80,000 times smaller than the width of a human hair. Silica microspheres can also be stirred into hot or cold liquid cosmetics that won’t be ground. Stir or hand-mash into powdered cosmetics after you are done using your coffee grinder grinding silica microspheres compromises their teensy sphere-ness. Wear a dust mask! Silica microspheres are very lightweight and prone to floating around and being inhaled. Calcium carbonate also has none of the light dispersion/blurring properties of silica microspheres. Calcium carbonate has similar oil absorbing properties, but the pH is much higher so it isn’t a good choice for eye products. Sericite mica can be a decent alternative, but it is not nearly as oil absorbent so if the recipe relies on the silica microspheres for a dry-touch finish that likely won’t be present. Silica microspheres are hard to substitute well. They can be hard to find in some parts of the world, and may be too drying for some skin types. Silica microspheres only exist as a refined product.Įxtremely effective oil absorption, light diffusion, and improved slip. If you want to make colour cosmetics I highly recommend owning some silica microspheres.
I love silica microspheres in all kinds of cosmetics for oil absorption, light diffusion, and improved slip. Try blending a drop or two of oil with a tiny sprinkle of silica microspheres and rubbing that into your hand to see what I mean! I include silica microspheres in cream cosmetics and oil serums because they give the end product a beautiful dry-touch finish that is incredibly luxurious and feels very expensive. I use silica microspheres in a lot of eye makeup formulas because they improve the slip/glide of the product and help with oil control, which helps improve wear time.
Silica microspheres improve slip, reduce the oily feel of products, and help improve the appearance of the skin by diffusing light for a real-life airbrushing effect. Incredibly soft and smooth with a silky, dry finish.īecause they’re magic, basically. Silica is a naturally occurring mineral found in everything from granite to sand.ġ–15%, up to 100% (watch for the product being too drying) Silica microspheres is an “ an amorphous hydrated silica” in a microsphere (super tiny ball) format.
