Cosmetic Peeling Capsules with Melting Wax Shell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic peeling preparations with salt slurries in oil face issues of sedimentation and uneven mixing, leading to inefficient use and skin irritation due to surfactants, while existing capsule forms suffer from smearing and poor distribution on the skin.
Innovation Solution
Development of cosmetic capsules with a dimensionally stable wax-based shell and an oil or lipid mixture filling, incorporating abrasive substances like salt, which dissolves or melts upon application, ensuring even distribution and moisturizing effects without skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If salt slurry is used in cosmetic peeling preparations, then peeling effect is achieved, but sedimentation and uneven mixing occur
Solution Approach 1:
The peeling preparation is segmented into discrete capsules, each containing a controlled amount of salt slurry in oil. This segmentation prevents sedimentation at the bottom of a container and ensures uniform distribution of abrasive particles throughout the oil phase, as each capsule is a self-contained unit that melts uniformly on application.
Solution Approach 2:
The invention changes the physical state parameters by formulating the capsule shell to melt at skin temperature or body temperature, transforming the salt slurry from a settled mixture into a uniformly distributed peeling preparation. The phase change from solid capsule to liquid/semi-liquid state ensures complete mixing of salt and oil without sedimentation.
2Ease of operation
If surfactants are added to remove plastic particles, then cleaning effect is improved, but skin lipids are removed causing tightness
Solution Approach 1:
The invention converts the potential harm of strong cleaning agents into a beneficial effect by using the melting capsule shell itself as the distribution medium. The shell material, when melted, naturally distributes the abrasive particles without requiring surfactants, thus achieving particle removal while preserving skin lipids and avoiding the tight, dry feeling associated with surfactant use.
3Productivity
If emulsion capsules are used, then single-use dosage is achieved, but capsule shell smears on skin
Solution Approach 1:
The invention modifies the thermal parameters of the capsule shell material, selecting waxes and lipids that melt at or near skin temperature. This parameter change ensures that the capsule shell transitions from a solid, smearing form to a liquid or semi-liquid state that distributes evenly across the skin surface, eliminating the smearing problem while maintaining single-use dosage convenience.
4Reliability
If salt particles are used for peeling, then abrasive effect is achieved, but uneven distribution and oil depletion occur
Solution Approach 1:
By encapsulating the salt particles within individual capsules, the invention ensures that each application contains a pre-measured, uniform distribution of abrasive particles suspended in oil. This segmentation prevents the salt particles from settling and separating, ensuring consistent peeling effect with every use while maintaining product uniformity throughout the container's shelf life.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The capsules provide a consistent peeling effect, improve mixing efficiency, and maintain skin hydration by dissolving the shell and filling, allowing for easy washing and reducing skin dryness.
Implementation Method 1
it melts and/or becomes completely or partially liquid due to shearing forces and/or it dissolves in the filling and/or the skin sebum lipids or through mixing of the inner phase and the shell material
Implementation Method 2
it melts and/or becomes completely or partially liquid due to shearing forces and/or it dissolves in the filling and/or the skin sebum lipids
