Thinner, Softer.
In line with the “no-makeup makeup” trend, base formulations now prioritize delivering a natural and lightweight feel through advanced technology.
In this newsletter, we introduce an SPF50 PA++++ BB Stick formulated with SUNPRESS-TR, a plate-shaped powder that enables a natural skin finish, and MLB-Polar, an emulsifier that ensures long-lasting stability of the formula.
As clean beauty ingredients, these two materials demonstrate how technology can meet consumers’ demand for natural, effortless beauty.
What is SUNPRESS-TR?
SUNPRESS-TR is a next-generation plate-shaped powder developed as a safe and effective alternative to talc.
Thanks to its low friction coefficient and excellent moldability, it ensures a smooth, even, and comfortable application, making formulations feel softer and more natural on the skin.
When used together with plate-shaped powder SUNPRESS-TR, rather than using spherical silica powder alone, the structural differences between the two powders work complementarily to evenly fill pores and skin irregularities.
This ensures a smooth, flawless coverage with strong adherence that keeps makeup intact for longer.
What is MLB-Polar?
MLB-Polar is a hectorite-based emulsifier designed for clean beauty formulations. Even at low concentrations, it delivers excellent emulsion stability in polar oil systems, providing a smooth, non-sticky feel for a comfortable and long-lasting application.
When other emulsifiers are used, pigment particles can clump or separate, reducing formula stability. In contrast, with MLB-Polar, pigments are evenly dispersed, creating a smooth, stable formula with a consistent texture that lasts.
The BB Sun Stick combines clean beauty with high performance, delivering a perfectly balanced coverage, texture, and feel in one multi-purpose stick.
With powerful SPF50+ PA++++ sun protection, it’s set to become the next-generation all-in-one solution for effortless, natural beauty.
