Silk fiber is an abundant natural source of a protein known as fibroin and has been used nutritionally for hundreds of years as a functional ingredient in pharmaceutical applications. More recently, silk fiber has been gaining popularity in cosmetic and personal care applications due to its fibroin content and valuable contribution towards nourishing the skin and hair. It is also admired for its ability to lend a smooth, silky feel to cosmetic formulations.

Superfine Silk Powder is 100% natural silk protein powder that is useful in any type of cosmetic powder formulations where oil absorption, smooth application and slip are desired. Superfine Silk Powder has a particle size of < 5 microns.

Our Superfine Silk Powder is a pure, silk protein powder that preserves the natural composition and physical structure of cocoon silk. The powder is extremely fine in texture and possesses a very smooth, silky feel. Our Superfine Silk Powder is meticulously processed to preserve the natural amino acid and trace mineral composition and physical structure of cocoon silk. To produce the powder, milled, raw silk fiber undergoes alkaline hydrolysis, dealkylation and is then dried and carefully packaged.


Superfine Silk Powder is valued as a filler in mineral makeup formulations to help soften the appearance of fine lines, provide moisture balance, absorb excess oil and provide a silky slip.
