Emulsion is a cream-like liquid skin care product that is rich in moisturizing ingredients, making it an ideal choice for people with dry skin during the spring and autumn seasons. It is also suitable for those with normal skin in all seasons. To extend its shelf life, emulsions generally contain solid oils that help to shield the skin from the harsh effects of the dry climate outside, preventing excessive moisture loss, and avoiding chapped skin. Therefore, during dry seasons, it becomes essential to include emulsion as a key player in your skin care routine before stepping out.
Preparation technology for emulsions presents greater difficulty compared to solid creams due to the requirement of balancing fluidity and stability to prevent separation during storage. To enhance stability, manufacturers meticulously select oil and water phase materials with similar densities, along with appropriate emulsifiers. A more effective approach involves utilizing multiple emulsifiers with synergistic effects instead of relying on a single emulsifier. Moreover, in addition to incorporating a suitable emulsifier into the internal ingredients, merchants also prioritize the use of outer packaging bottles that provide superior isolation. Whether opting for easily transportable plastic bottles or preservation-friendly glass bottles, all these emulsion containers can be recycled as waste.
