What Role Does Silica Play in Cosmetic Formulations?
Silica is an essential ingredient in cosmetic formulations, performing a wide range of functions depending on its particle size, specific surface area, porosity, surface treatment, coating materials, and oil absorption capacity. It can provide a silky and smooth texture, achieve a soft-focus effect, absorb oil, or even serve as a carrier for active ingredients.
Over the next four weeks, Sunjin Beauty Science will introduce its own unique silica solutions that offer a variety of roles and possibilities.
We begin with the SUNSIL-OLEO Series, a lipophilic silica that tackles the dual challenge of controlling sebum while maintaining skin hydration.
By treating natural silica with Cetyl Alcohol both inside and out, SUNSIL-OLEO effectively absorbs excess oil while also delivering moisturizing benefits. Let’s take a closer look at the unique role of SUNSIL-OLEO starting today.
SUNSIL-OLEO Series: Lipophilic Silica that selectively absorbs Oil
The SUNSIL-OLEO series, created with naturally derived silica treated both internally and externally with Cetyl Alcohol, offers the benefit of selectively absorbing sebum while protecting the skin’s moisture.
With these unique benefits, it offers a safe and sustainable alternative to porous PMMA—completely free from microplastic concerns.
In addition, the lipophilic SUNSIL-OLEO series offers outstanding advantages such as rapid absorption, excellent compatibility with thickeners, smooth application, and a non-clumping texture, making it highly suitable for skincare products.
Sunjin Beauty Science recreates the unique texture of microplastic beads using mineral-derived silica, offering products like the elastic SUNSIL-SILK as a substitute for silicone powder and SUNSIL-SOFT2, which blends SUNSIL-SILK with macadamia seed oil for a soft texture to replace nylon-12.
Silica, the most abundant compound on Earth, constituting 59% of the planet’s crust, is a key component of rocks and sand. Harnessing this natural resource, Sunjin Beauty Science is committed to embarking on a journey toward sustainable beauty with you.
If you’re seeking innovative solutions to overcome formulation challenges with sustainable silica, visit Sunjin’s booth at in-cosmetics Asia in Bangkok. We look forward to bringing your ideas to life and discussing the future of sustainable beauty together.
With powerful SPF50+ PA++++ sun protection, it’s set to become the next-generation all-in-one solution for effortless, natural beauty.
