Silicone blend for a dry, silky feel in skin and hair care

BRB 1840 is a clear solution of dimethiconol gum in cyclopentasiloxane (INCI: Cyclopentasiloxane (and) Dimethiconol). The product is 100 % silicone, contains 11 % dimethiconol and has a viscosity of approx. 1500 mm²/s. In cosmetic formulations BRB 1840 gives the skin a dry, silky feel and gives hair shine and a strong conditioning effect.

Key benefits

• Silky skin feel: a soft, dry and silky result.
• Better spreadability: formulations are easier to apply and spread well.
• Breathable film: forms a non-occlusive, water-repellent film on skin and hair.
• Substantivity: helps other ingredients adhere better to the skin surface.
• Shine and conditioning: gives hair shine and helps protect it from external damage.

Typical applications

• ✓ Skin care: creams, lotions and serums
• ✓ Hair care: conditioners, styling products and hair masks
• ✓ Make-up: foundations and primers

Processing

1. Add BRB 1840 to the oil phase of your formulation.
2. Emulsify into an oil-in-water emulsion at high speed.
3. Keep the temperature below 50 °C to prevent evaporation of cyclopentasiloxane.

Points of attention

• ✓ Cyclopentasiloxane (D5) falls under the European REACH restriction on D4, D5 and D6 in cosmetics (Annex XVII, entry 70). Check which limits and transition periods apply to your application.
• ✓ For future-proof formulations we recommend switching to linear silicones. One alternative is BRB 1740 Dimethicone and Dimethiconol. Expect small differences in the end result and start reformulating in good time.
• ✓ Store the container tightly closed in a dry, well-ventilated place and avoid heat.
