Answer
Understanding the Oily Texture of the Serum
The oily texture of this serum is primarily due to the high concentration of oils and emollients in the formulation.
Key ingredients contributing to this feel include:
- Mineral oil (Paraffinum Liquidum): A common emollient and base oil that provides a smooth, soft feel to the skin.
- Cetearyl Isononanoate: Another emollient that adds to the product's texture and feel.
- Hydrogenated Styrene/Isoprene Copolymer: This ingredient functions as a gelling agent specifically designed to thicken and stabilize the oil phase of the product, helping to create a consistent, gel-like texture for the oils.
The combination of these and other oily components in the formula, used at high levels, results in the characteristic oily texture you observed.
