Cyclopentasiloxane Dimethiconol BC 2231 1 kg

A weightless silicone blend built for hair serums and conditioning formulas

Cyclopentasiloxane Dimethiconol BC 2231 is a volatile silicone complex that pairs the light, quick-spreading feel of cyclopentasiloxane with the film-forming, conditioning behavior of dimethiconol. This combination is used mainly in the personal care industry, especially in leave-in hair treatments, anti-frizz serums, hand and body creams, and makeup primers. The material belongs to the Silicones and Conditioning Surfactants for Hair category, gathering raw ingredients used to build slip and lightweight coverage on hair fibers without any greasy residue.

The primary use case is in styling and conditioning products: leave-in fluids, smoothing serums, post-wash lotions, and treatments for split ends. Cyclopentasiloxane evaporates off the hair shaft, leaving behind a thin dimethiconol film that reduces static, eases combing, and adds a soft, natural-looking sheen without weighing the strands down. In skin care and color cosmetics, formulators rely on the same silicone blend inside primers and moisturizing emulsions to achieve smooth glide and pore-blurring optical effects. A smaller share of demand comes from industrial polishing compounds and textile finishing, where the blend provides slip without tackiness, though the cosmetic sector remains the dominant market globally.

In terms of compatibility, this silicone blend pairs well with other silicone fluids and emulsions, as well as cationic conditioning agents. In multi-step hair formulas it is frequently combined with Hairless silicone fluid to intensify smoothing on porous or curly hair, and with Polyquaternium 22 for extra charge neutralization and moisture retention. For a lighter, less silicone-heavy feel in lotions and emulsions, formulators often blend it with Coco Caprylate, which softens the film sensation and improves spreadability on skin.

A typical usage rate ranges from 1 to 6 grams per 100 grams of finished formula, depending on the desired texture and product type: lighter sprays call for the lower end, while richer leave-in serums and creams use the higher end. The ingredient should be added during the cooling phase, at temperatures no higher than 40-45 degrees Celsius, after the main emulsion has formed, with gentle mixing until uniform - no additional heating is required. The 1 kg packaging suits small-batch and studio-scale production, giving labs and independent brands enough volume for consistent, repeatable leave-in product runs without frequent reordering. Store the raw material in a tightly sealed container, in a cool, dry place away from direct sunlight and heat sources to preserve its flow and conditioning performance for the full shelf life.
