Solid Soap Composition with Polysiloxane and Diamine for Makeup Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current face cleaners that aim to remove makeup and clean the skin in a single step often lack sufficient foaming properties and struggle to completely remove acid pigments like lipsticks, leaving a residue on the skin and not providing a clean feel.
Innovation Solution
A solid soap composition combining polyoxyalkylene-modified polysiloxane and tetrakis (2-hydroxyalkyl) ethylene diamine with a soap component, along with additional surfactants and polyhydric alcohols, to enhance foaming properties and effectively remove both cosmetic foundations and acid pigments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polyoxyalkylene-modified polysiloxane is used to remove makeup cosmetic materials, then makeup removal capability is improved, but foaming property becomes insufficient and clean feel cannot be obtained
Solution Approach 1:
The invention combines polyoxyalkylene-modified polysiloxane with soap components and specific surfactants to create a composite cleaning composition. This composite approach allows the polysiloxane to effectively remove makeup while the soap and surfactant components provide sufficient foaming and prevent residue, thus resolving the contradiction between makeup removal capability and foaming property.
Solution Approach 2:
The invention optimizes the concentration ratios of different components, specifically setting polyoxyalkylene-modified polysiloxane at 1-15 wt%, soap components at 20-80 wt%, and surfactants at 1-30 wt%. By adjusting these parameter ranges, the composition achieves both effective makeup removal and adequate foaming properties, eliminating the residue issue while maintaining high makeup removal capability.
2Ease of operation
If ordinary face cleaner is used for facial cleaning, then cleaning simplicity is improved, but acid pigments cannot be sufficiently removed
Solution Approach 1:
The invention creates a composite face cleaner containing polyoxyalkylene-modified polysiloxane, soap components, and specific surfactants. This composite formulation enables single-step cleaning to effectively remove acid pigments like lipsticks while maintaining ease of use, thus resolving the contradiction between cleaning simplicity and acid pigment removal capability.
Solution Approach 2:
The invention designs a multi-functional face cleaner that simultaneously performs makeup removal, acid pigment removal, and skin cleaning in a single step. The combination of polysiloxane for makeup removal, surfactants for acid pigment removal, and soap components for general cleaning creates a universal cleaner that handles multiple cleaning tasks, achieving both simplicity and effectiveness.
3Reliability
If cleanser containing large amount of oil is used for makeup removal, then makeup removal capability is improved, but oil remains on skin and clean feel cannot be obtained
Solution Approach 1:
The invention changes the composition parameters by using polyoxyalkylene-modified polysiloxane at controlled concentrations (1-15 wt%) combined with surfactants and soap components. This parameter optimization allows effective makeup removal through the polysiloxane while the surfactant and soap components ensure complete removal of oil residues, providing a clean feel after washing.
Solution Approach 2:
The invention introduces surfactants and soap components as intermediary substances that facilitate the complete removal of oil from the skin. These intermediaries work between the makeup removal action of polysiloxane and the final skin state, ensuring that no oil residue remains after cleaning while maintaining effective makeup removal capability.

AI summary
A solid soap composition which comprises as essential ingredients a soap ingredient (a), a specific polyoxyalkylene-modified polysiloxane Co), and a tetrakis(2-hydroxyalkyl)ethylenediamine(c). It is a detergent with which makeup removal and ordinary face washing can be simultaneously conducted at a time. It lathers well and gives a fresh use feeling after washing. It can sufficiently remove not only foundations but acid pigments.
