Mild Cleansing Composition with Saturated Active Ingredients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin cleaning and care products often fail to provide thorough cleaning without damaging the skin's natural barrier, and they struggle to effectively deliver active ingredients for skin enhancement.
Innovation Solution
A mild cleansing composition nearly saturated, saturated, or supersaturated with an active ingredient, incorporating a combination of mild surfactants such as long-chain betaine, sodium lauroyl sarcosinate, and potassium cocoyl glycinate, along with extracts from plants like Angelica dahurica and Wolfiporia extensa, which enhances skin absorption and care.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cleaning preparation removes dirt by dissolution, then cleaning effectiveness is improved, but skin barrier damage and dryness occur
Solution Approach 1:
The patent combines dissolution and emulsification mechanisms into a single cleaning preparation. The composition contains both surfactants for emulsification and solvents for dissolution, allowing simultaneous operation of both mechanisms to achieve thorough cleaning while maintaining skin barrier integrity through the balanced formulation.
Solution Approach 2:
The cleaning preparation uses a composite formulation containing multiple components including surfactants, solvents, and active ingredients at specific concentrations. This composite structure enables the preparation to exhibit both emulsification and dissolution properties, resolving the contradiction between cleaning effectiveness and skin safety.
2Object-affected harmful factors
If a cleaning preparation removes dirt by emulsification, then skin gentleness is improved, but cleaning completeness deteriorates due to residual emulsified particles
Solution Approach 1:
The patent merges emulsification and dissolution mechanisms in one preparation. The dissolution component ensures complete removal of dirt and prevents accumulation of emulsified particles, while the emulsification component maintains skin gentleness. This combination resolves the contradiction between cleaning completeness and skin gentleness.
3Productivity
If active ingredient concentration is increased for better skin care effects, then skin care effectiveness is improved, but physical and chemical stability deteriorates
Solution Approach 1:
The patent optimizes the concentration parameters of active ingredients within specific ranges (0.1-10% for plant extracts, 0.01-1% for other active ingredients) to achieve the balance between skin care effectiveness and formulation stability. This parameter optimization allows high enough concentration for effectiveness while maintaining physical and chemical stability.
Solution Approach 2:
The use of composite material system with multiple stabilizing components and synergistic ingredients allows the formulation to maintain stability even at higher active ingredient concentrations. The composite structure provides mutual support among components, preventing degradation and maintaining formulation integrity.
4Productivity
If active ingredient concentration is increased to overcome skin barriers, then absorption effectiveness is improved, but formulation stability and safety deteriorate
Solution Approach 1:
The patent carefully adjusts active ingredient concentrations within optimized ranges that are high enough to overcome skin barriers effectively but low enough to maintain formulation safety and stability. This parameter control ensures adequate absorption without compromising safety.
Solution Approach 2:
The patent uses surfactants and other formulation components as intermediaries that facilitate the penetration of active ingredients through skin barriers. These intermediary substances enhance absorption effectiveness without requiring excessively high concentrations of active ingredients, thereby maintaining formulation safety.
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 composition effectively cleans the skin without excessive stripping, enhances skin absorption of active ingredients, and provides skin care benefits such as whitening, collagen synthesis promotion, inflammation reduction, and hydration.
Implementation Method 1
The composition includes at least one surfactant and is nearly saturated, saturated, or supersaturated with at least one active ingredient
Implementation Method 2
The transdermal delivery system (TDDS) for a drug or cosmetic product generally has the following two paths: 1. penetrating the stratum corneum directly or through the lipid bilayers in the gaps between keratinocytes

AI summary
A mild cleansing composition nearly saturated, saturated, or supersaturated with at least one active ingredient includes one or more surfactants and one or more active ingredients. The mild cleansing composition can be used to clean the skin and improve skin texture (e.g., the degree of radiance and wrinkles) at the same time.
