Feature Spotlight, WACKER’s D5-Free Silicone Portfolio for Personal Care
Evolving Toward Compliance and Innovation
With the growing regulatory restrictions around Cyclomethicone (D5), including limitations in the EU and scrutiny in global markets, formulators are seeking high-performance, environmentally responsible alternatives. Recognizing this shift, WACKER has strategically developed a portfolio of D5-free silicone materials under its BELSIL® product line, offering exceptional sensorial and functional properties across a wide range of personal care formulations. These alternatives support product innovation while helping brands align with regulatory and sustainability goals.
BELSIL® Technologies and Product Portfolio
WACKER’s D5 alternatives are grouped into key categories, each designed to replace D5 in both performance and sensory feel, without formulation compromise.
1. Gum Blends: High-Performance Film Formers
- BELSIL® GB 3010 & GB 3031 JP
Volatile isododecane-based gum blends that leave behind a flexible silicone film after evaporation. Ideal for lightweight, fast-absorbing textures. - BELSIL® DM 3096 & GB 1020 (incl. eco variants)
Dimethicone-based gum blends that offer a longer play time, improved skin elasticity, and a rich feel. Suitable for creams, lotions, and hair treatments. - Eco Grades (e.g., eco DM 3096)
Certified under REDcert², these products are chemically identical to their conventional counterparts but use a bio-mass balance approach, making them a sustainable 1:1 replacement.
2. Elastomer Gels: Mattifying & Blurring Experts
- BELSIL® EG 7
A non-volatile dimethicone-based elastomer gel known for its soft-focus, mattifying, and blurring effects. It enhances spreadability, reduces tackiness, and improves the visual texture of skin—perfect for facial moisturizers, primers, and BB creams. - BELSIL® EG 3000
Designed with isohexadecane, this volatile and EWG-compliant elastomer gel offers quick drying and a silky after-feel. Its shear-thinning behavior also makes it easy to incorporate into cooling lotions, sunscreens, and foundations that require elegant glide and finish.
3. Silicone Emulsifiers: Versatile Stability Agents
- BELSIL® WO 5000
A silicone polyglycoside emulsifier that functions as a W/O co-emulsifier. It enhances pigment dispersion, prevents sedimentation, and allows formulation of light and low-viscosity emulsions. Particularly advantageous for color cosmetics and high-SPF sun care products.
Sensory and Functional Benefits
WACKER’s D5 alternatives are not only regulatory-compliant but also offer sensory profiles that match or surpass D5:
-
Enhanced slip and spreadability
-
Long-lasting hydration
-
Improved transfer resistance and film formation
-
Noticeable soft focus and mattifying finish
-
Suitable for clear gel textures, thanks to high compatibility with water and polar ingredients (e.g., REG 1103 B)
