On the dazzling shelves of cosmetics, those crystal-clear gel waters and clear facial cleansers always catch consumers' eyes first. However, to perfectly blend oily components (such as silicone oil) with water and maintain long-term transparency and stability is no easy task. Behind this, there is a key ingredient - PEG/PPG-15/10 Polydimethylsiloxane.
This is a magical "dual-polarity" molecule. In its molecular structure, it retains the hydrophobic backbone of organic silicon oxygenane while grafting hydrophilic ethoxy groups. This unique structure gives it excellent water solubility, allowing it to easily dissolve in water, propylene glycol, and glycerin. More importantly, it has extremely low surface tension, which can act as a "mediator" to tightly bind the originally immiscible oil and water together, forming a stable emulsified system.
For formulators, it is the secret weapon for creating transparent products. Whether it is transparent toner or clear cream, it can ensure the stability of the formula while giving the product excellent spreadability. It can not only emulsify silicone oil but also increase the overall stability of the formula, preventing stratification or turbidity. In simple terms, it is because of PEG/PPG-15/10 Polydimethylsiloxane that our skin care products can have a refreshing texture while also having stable effects.
