Instantly Emulsified Cosmetics Apparatus with Segmented Fluid Channels

The patent applies preliminary action by pre-storing the internal fluid (containing functional raw materials) and external fluid (continuous phase) separately in containers within the cosmetic application device. These pre-prepared fluids are kept ready but not yet mixed, allowing the system to maintain productivity through pre-positioning materials while preserving freshness by delaying emulsion formation until the moment of use when the user applies the cosmetic

The patent segments the cosmetic emulsion into separate internal fluid and external fluid components that are stored independently. The internal fluid containing functional raw materials is separated from the external continuous phase fluid. This segmentation allows each component to be optimized and stored separately, then combined instantly during application, resolving the contradiction between advance manufacturing and freshness

The patent extracts and removes traditional emulsion-stabilizing additives like surfactants and thickeners from the formulation. Instead of relying on these additional substances, the system uses the inherent properties of the internal and external fluids combined with the controlled mixing process to achieve stability. This extraction of unnecessary additives reduces the quantity of additional substances while maintaining product stability through the novel delivery mechanism

The system enables self-service stability where the emulsion stabilizes itself through the controlled interaction between internal and external fluids in the mixing chamber, without requiring external stabilizing agents. The fluids self-organize into a stable emulsion structure upon mixing, eliminating the need for surfactants and thickeners that would otherwise be required to maintain stability

The patent applies preliminary action by pre-adjusting the pH of the internal fluid to the optimal range for functional raw material stability (e.g., pH 3-4 for vitamin derivatives) before mixing. The functional raw materials are incorporated into the internal fluid under these optimized conditions, maintaining their stability during storage. When mixed with the external fluid during application, the emulsion provides the functional materials in their stable, effective form without requiring prolonged exposure to extreme pH conditions that would cause irritation

The patent utilizes parameter changes by controlling the pH parameter of the internal fluid to match the optimal stability range for specific functional raw materials. For example, the internal fluid pH is adjusted to 3-4 for vitamin derivatives to maintain their stable state. This parameter optimization allows the functional materials to remain stable during storage while minimizing harmful effects during use, as the stable emulsion form reduces irritation compared to concentrated unstable formulations

The patent applies preliminary action by pre-dissolving vitamin C in polyol under controlled conditions to form a stable solution before incorporation into the internal fluid. This pre-preparation ensures vitamin C stability without requiring the formation of P/S emulsion particles through heating. The resulting cosmetic maintains vitamin C stability while avoiding the sticky feeling associated with conventional P/S emulsion methods

The patent utilizes parameter changes by optimizing the temperature and concentration parameters during the dissolution of vitamin C in polyol. Instead of high-temperature heating that creates sticky P/S emulsion particles, the system uses controlled lower-temperature dissolution parameters. This parameter optimization maintains vitamin C stability while producing a non-sticky cosmetic texture that improves customer satisfaction
