Cleansing Composition Using Stearic Esters and Branched Hydrocarbons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current facial cleansers often compromise on cleansing efficiency or cause irritation while trying to remove makeup, especially around sensitive areas like the eyes, and struggle to provide a pleasant, non-greasy feel.
Innovation Solution
A cleansing composition incorporating a blend of stearic esters and a branched hydrocarbon, optionally with nonionic sucrose or glucose fatty acid esters and a Carbomer Interpolymer thickener, embedded in a substrate like a nonwoven wipe, designed to effectively remove cosmetics like mascara, foundation, and eyeliner with reduced irritation and residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional facial cleansers use strong cleansing agents to remove makeup, then cleansing efficiency is improved, but skin and eye irritation increases
Solution Approach 1:
The patent changes the chemical parameters of the cleansing system by using stearic esters (isostearyl isostearate and decyl isostearate) instead of conventional strong surfactants. These esters have different chemical properties that provide effective makeup removal while being gentler on skin and eyes, directly resolving the contradiction between cleansing power and irritation.
Solution Approach 2:
The invention creates a composite cleansing system combining multiple stearic esters with branched hydrocarbons and nonionic sucrose or glucose fatty acid esters. This composite formulation achieves synergistic effects where the combination provides superior cleansing efficiency while maintaining low irritation, overcoming the limitations of single-agent systems.
2Object-affected harmful factors
If conventional cleansers use occlusive agents to reduce irritation, then skin comfort is improved, but greasiness and residue increase
Solution Approach 1:
The patent changes the physical parameters of the formulation by selecting stearic esters with specific molecular structures that have appropriate viscosity and spreading characteristics. These esters provide protection and comfort without the heavy occlusive feel, and the Carbomer thickener further modifies the rheology to eliminate greasiness while maintaining comfort.
Solution Approach 2:
The invention applies different functional components in specific proportions: stearic esters for gentle cleansing, branched hydrocarbons for moisturization without greasiness, and Carbomer for texture control. Each component is optimized for its specific function, creating a balanced formulation that reduces irritation without leaving residue.
3Productivity
If conventional formulations use high concentrations of active ingredients to improve cleansing, then makeup removal is improved, but pleasant feel and moisturization are reduced
Solution Approach 1:
The patent formulates a composite system where stearic esters provide the primary cleansing action for effective makeup removal, while branched hydrocarbons and nonionic sucrose or glucose fatty acid esters provide moisturization and pleasant feel. The Carbomer thickener ensures proper product texture and spreadability. This multi-component approach achieves both high cleansing performance and sensory comfort.
Solution Approach 2:
The invention optimizes the concentration parameters of each component: stearic esters at effective levels for makeup removal, branched hydrocarbons at levels sufficient for moisturization, and Carbomer at concentrations that provide ideal rheology. This parameter optimization ensures both cleansing efficacy and pleasant user experience.
