On the occasion of in-cosmetics Global, which took place from April 8 to 10, 2025 in Amsterdam, The Netherlands, Roquette Beauté has introduced its latest ingredient, Beauté by Roquette ST 305 (INCI: Amylopectin).
Porous structure
With its patent-pending porous structure, this ingredient offers an alternative to mineral and synthetic powders, bringing unique sensory benefits and compaction properties across various cosmetic applications, including makeup, skin care, toiletries, hair care, and fragrances.
“What makes Beauté by Roquette ST 305 unique is its advanced patent-pending porous structure, obtained through enzymatic hydrolysis, that brings exceptional compaction properties compared to other natural powders on the market,” said Roquette Beauté.
Beauté by Roquette ST 305 is a readily biodegradable and non-ecotoxic powder, with a white color. It is talc-free and free from nanoparticles.
The sensory and compaction properties of Beauté by Roquette ST 305, as well as its affinity with various oils and water, provide cosmetic formulators with the flexibility to use it in a wide range of cosmetic applications, including makeup, skin care, toiletries, hair care, and fragrances whether in loose or compacted forms.
Maintaining color integrity
Beauté by Roquette ST 305 excels in maintaining color integrity. In tests [1], this ingredient demonstrated superior color retention, outperforming native corn starch and equaling the performance of talc and porous silica beads. These benefits eliminate the need for additional pigments, making it a cost-effective and attractive solution for color cosmetic products.
Additionally, Beauté by Roquette ST 305 is brighter than talc, silica, and porous silica, while being less yellow than other natural sensory powders derived from native corn starch.
Matte finish and shine control
In addition, Beauté by Roquette ST 305 offers superior mattifying power, making it ideal for matt-finish color cosmetics, like lipsticks. Tests [2] have shown that this sensory powder significantly reduces shine, delivering a flawless matte finish in makeup products. In foundation formulations, Beauté by Roquette ST 305 achieved a 96% reduction in shine compared to placebo. [3]
Its sebum absorption capabilities also outperformed native corn starch and silica beads and were comparable to polymethyl methacrylate (PMMA). These attributes make Beauté by Roquette ST 305 ideal for controlling sebum, ensuring a long-lasting matte appearance.
Furthermore, at a concentration of 65% in a loose powder formulation, Beauté by Roquette ST 305 proved to smooth crow’s feet, blur the eye contour, and improve skin texture, providing a flawless and youthful appearance.
“We are very proud of the addition of Beauté by Roquette ST 305 to our product range,” says Bénédicte Courel, General Manager of Roquette Beauté. “We believe, it is a real game-changer and responds to the growing need for cleaner label ingredients in the cosmetics market. The unique sensory and compaction properties of Beauté by Roquette ST 305, as well as its affinity with various oils and water, provide cosmetic formulators with the flexibility to create high-performance products across a variety of cosmetic applications.”
