We often get asked why Gold Cosmetica produces and offers 24K gold leaves but no 24K gold flakes?
The answer is simple:
During the production process, we first beat the cosmetic gold into very thin leaves, and then grind and sift it into flakes and powders of various particle sizes. Since pure 24 karat gold (999) does not contain any additional components, the thin leaves are very soft and almost “sticky”.
This is called a cohesion. The cohesive forces are from electrical origin and are also known as van der Waals forces named after the Dutch physicist Van der Waals.
These forces are the reason why pure 24K gold flakes for cosmetics generally clump together. The flakes stick together and are not recommended for use in cosmetic formulations.
But there is a solution
Since we do not want to offer any defective products to our customers in the cosmetics industry, we have developed a solution:
With the alloy Gold 985 we offer an optimized flake for cosmetics. It consists of 98.5% gold and a tiny amount of copper and silver, which makes the material slightly harder and thereby positively changes the cohesive forces. As a result, the cosmetic gold leaf does not stick together and the final gold flake has an excellent volume.
The result are high quality and visually flawless gold flakes for your cosmetic formulation.
Particle size recommendation
If you want to give your product an exclusive gold shimmer, we recommend our powder No 7. However, if you want the gold to be clearly visible in your cosmetic product, our flake No 5 is very likely the product you are looking for.
