With the EU REACH Regulation (EU) 2024/1328 banning D5 (Cyclopentasiloxane) at ≥0.1% from June 2026, the cosmetics industry urgently needs a reliable alternative. SQ-SIL 1.5 is a low viscosity Dimethicone (1.5cSt) volatile silicone oil that serves as the perfect D5 replacement. With <0.1% cyclic residues, full EU compliance, and a lightweight, non-greasy feel, this cyclopentasiloxane alternative offers superior spreadability and moderate evaporation without compromising sensory performance. Ideal for skincare, hair care, sun care, and color cosmetics.

SQ-SE 785 is an anionic, low-viscosity Silicone Emulsion for Shampoo engineered for 2-in-1 systems. This premium Hair Conditioning Silicone delivers exceptional wet and dry combing, imparts luminous silkiness, and preserves foam volume even at 2.0–5.0% usage. With particle size ≤2μm and solid content ≥50%, it outperforms conventional emulsions in stability and cost. Also ideal as Silicone Emulsion for Hair Mask and rinse-off treatments. The definitive Dimethicone Emulsion for Hair Care.

SQ-SE 8100 (Polyurethane-35) is a waterborne film former engineered for sunscreens. It tackles anti-migration, whitening prevention, abrasion resistance, and SPF boosting. Just 2% active content doubles SPF, eliminates white cast from physical filters, withstands rubbing, and locks UV filters uniformly on skin. Its flexible, breathable film delivers dry-touch comfort. Cold-process compatible, it reduces costs and UV filter usage – the ultimate sunscreen accelerator.

Most film formers force you to compromise—acrylates crack, waxes melt, PVP smudges. SQ‑SE 8100 (Polyurethane‑35) is different. It delivers flexible, water‑resistant, oil‑proof films that stay intact through sweat, sebum, and movement. In mascara, it stops flaking. In eyeliner, it prevents melting into dark circles. In foundation, it eliminates white sweat streaks and patchy melting. No trade‑offs.

Tired of peel-off masks that hurt, leave residue, and damage your skin barrier? SQ-SE 8100 (Polyurethane-35) is a game-changing film former that creates soft, flexible, intact films that peel off gently — no pain, no residue, no barrier damage. Perfect for peel-off masks, mascara, eyeliner, and peel-off nail polish. Cold-process compatible.Discover the gentle revolution in film-forming technology.

In complex shampoo formulations containing cationic guar and polyquaterniums, conventional anionic opacifiers often cause precipitation and discoloration due to charge conflict. SQ-OP 31N, a non-ionic opacifier based on Styrene/Acrylamide Copolymer, carries no charge—eliminating reactivity with cationic ingredients and delivering superior formulation stability. As a premium cosmetic ingredient, it offers exceptional anti-precipitation performance and system compatibility, making it the ideal opacifier for conditioning shampoos and complex formulations, ensuring a consistently milky white appearance.
