Solid Cosmetic Composition with Dual Solidifying Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid cosmetics, such as lipsticks, cannot incorporate moisturizers with occlusion effects due to the limitations of solidifying agents used, as they either fail to solidify with oil contents or separate when mixed with water-soluble solids.
Innovation Solution
A cosmetic composition is developed using a single-phase composition with an oily liquid medium, an aqueous liquid medium, and solidifying agents that form a homogeneous phase, allowing for the integration of moisturizers with occlusion effects by using specific phenyl-containing substances, PABA derivatives, salicylic acid derivatives, and other compounds, which are soluble in either the oily or aqueous phase, and gelling/solidifying agents like polyethylene glycol and 12-hydroxystearic acid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If solid oils or oily gelling agents are used to solidify cosmetics, then the cosmetic achieves solid form, but it cannot dissolve moisturizers effectively
Solution Approach 1:
The invention uses a composite solidifying system combining both water-soluble solidifying agents (polyethylene glycol, polypropylene glycol) and oil-soluble solidifying agents (12-hydroxystearic acid). This composite approach allows the formulation to simultaneously achieve solid form while dissolving both water-soluble and oil-soluble moisturizers, resolving the contradiction between solidification and moisturizer compatibility
Solution Approach 2:
The invention changes the chemical parameters of the solidifying agents by selecting specific compounds with different solubility characteristics. By using polyethylene glycol (water-soluble) and 12-hydroxystearic acid (oil-soluble) together, the system can dissolve diverse moisturizers while maintaining solid form, overcoming the limitation of conventional single-type solidifying agents
2Stability of the object's composition
If water-soluble solids are used, then moisturizers can be blended easily, but oil contents with occlusion effect cannot be solidified
Solution Approach 1:
The invention employs a composite solidifying system that includes both water-soluble agents (for moisturizer blending) and oil-soluble agents (12-hydroxystearic acid for oil solidification). This dual-component approach enables simultaneous achievement of easy moisturizer blending and effective oil content solidification
Solution Approach 2:
The solidifying agent system performs multiple functions: polyethylene glycol handles water-soluble moisturizers, while 12-hydroxystearic acid handles oil-soluble components. This multi-functional approach allows a single cosmetic formulation to achieve both moisturizer blending and oil solidification that conventional single-type agents cannot accomplish
3Shape
If conventional solidifying agents are used, then solid cosmetics can be produced, but they separate when mixed with water
Solution Approach 1:
The invention changes the hydrophilic-lipophilic balance parameter of the solidifying system by selecting polyethylene glycol and polypropylene glycol with appropriate molecular weights and hydrophilic characteristics. These agents form homogeneous phases with both water and oil components, preventing separation while maintaining solid cosmetic structure
Solution Approach 2:
The polyethylene glycol and polypropylene glycol act as intermediary substances that are compatible with both aqueous and oily phases. They mediate between water and oil components, forming a homogeneous single phase that prevents separation, thus resolving the contradiction between solid form and phase stability
