BRB 423

Cetyl PEG/PPG-10/1 Dimethicone, also known as BRB 423, is a non-ionic silicone emulsifier developed by BRB International BV. It is commonly used in personal care and cosmetic formulations to stabilize oil-in-water (O/W) emulsions.

Description: BRB 423 is a block copolymer of cetyl alcohol (fatty alcohol) and polyethylene glycol (PEG) and polypropylene glycol (PPG) groups attached to a dimethicone backbone. This unique structure allows it to act as an effective emulsifier for combining oil and water phases in cosmetic and personal care products.

Function: As a non-ionic silicone emulsifier, BRB 423 facilitates the formation of stable emulsions by reducing the surface tension between oil and water phases. It helps to disperse oil droplets evenly throughout the water phase, preventing the separation of the two phases and creating a smooth, homogenous product.

Applications:

1. Moisturizers: BRB 423 is commonly used in water-based moisturizers to combine water and oil ingredients, creating a smooth, creamy texture.

2. Creams and Lotions: It is utilized in various creams and lotions to stabilize the emulsion and provide a pleasant, non-greasy feel on the skin.

3. Sunscreens: BRB 423 is added to sunscreens to enhance the emulsion stability and improve the spreadability of the product on the skin.

4. Foundations: The emulsifier is used in foundation formulations to achieve a smooth texture and even coverage.

5. Hair Conditioners: BRB 423 is incorporated into hair conditioners to stabilize the emulsion and provide easy spreadability through the hair.
