Solution Overview

Problem

There is a need for a cosmetic composition that can improve skin appearance and health without requiring additional skincare steps, addressing factors like age, hormonal changes, acne, and sunlight exposure, while being part of a daily cleansing routine.

Innovation Solution

A soap bar composition containing 20 to 80 wt% total fatty matter, 0.1 to 5 wt% electrolyte, 0.001 to 5 wt% PPAR activator (10-hydroxystearic or 12-hydroxystearic acid), and 1 to 45 wt% complex carbohydrate comprising starch, which provides skin benefits like glow, even tone, and clarity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cleansing products are used, then basic cleaning function is achieved, but skin health and appearance improvement is insufficient

Engineering Contradiction:
Improveskin health improvementVSAvoidadditional skincare steps
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The soap bar composition integrates multiple skin benefits into a single cleansing product. It combines PPAR activators for skin metabolism regulation, complex carbohydrates for barrier protection, and antioxidant agents for anti-aging, allowing one product to perform cleansing, moisturizing, protecting, and anti-aging functions simultaneously, eliminating the need for multiple separate skincare steps

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges traditionally separate skincare functions into one unified soap bar formulation. By combining PPAR activators (10-hydroxystearic acid, 12-hydroxystearic acid), complex carbohydrates (starch), and antioxidant agents in a single composition, it consolidates multiple skincare benefits that would otherwise require separate products into one daily cleansing routine

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If PPAR activators are added to soap composition, then skin metabolism normalization and anti-inflammatory benefits are achieved, but formulation complexity increases

Engineering Contradiction:
Improveskin metabolism regulationVSAvoidcomposition formulation
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention specifies precise concentration ranges for PPAR activators (0.01-5 wt%) and complex carbohydrates (1-45 wt%) to optimize skin benefits while maintaining formulation simplicity. By defining these parameter ranges, the patent provides clear formulation guidelines that balance efficacy with manufacturing feasibility, avoiding excessive complexity in the composition

Inventive Principle:
Principle #35Parameter changes

3Reliability

If complex carbohydrates comprising starch are added to soap composition, then skin barrier protection and moisturization are enhanced, but solubility and formulation stability may be affected

Engineering Contradiction:
Improveskin barrier protectionVSAvoidformulation stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent specifies optimal concentration ranges for complex carbohydrates (1-45 wt%) to maximize skin barrier benefits while minimizing formulation stability issues. By controlling the amount of starch and other complex carbohydrates within this range, the formulation achieves adequate solubility and stability while still providing effective skin protection and moisturization

Inventive Principle:
Principle #35Parameter changes

4Reliability

If multiple skin benefit agents are combined in soap composition, then synergistic skin benefits are achieved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvesynergistic skin benefitsVSAvoidingredient mixing accuracy
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent provides specific weight percentage ranges for each ingredient (PPAR activators: 0.01-5 wt%, complex carbohydrates: 1-45 wt%, antioxidant agents: 0.1-5 wt%) to facilitate accurate formulation and manufacturing. These parameter specifications enable consistent replication of the synergistic effects while maintaining practical manufacturing precision standards

Inventive Principle:
Principle #35Parameter changes

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 achieves synergistic skin benefits such as glow, even tone, and clarity by combining PPAR activators with complex carbohydrates, enhancing skin health through daily use without extra skincare steps.

Implementation Method 1

Peroxisome proliferator-activated receptors (abbreviated herein to PPAR) are transcription factors that control lipid metabolism. A range of specific fatty acids activates these factors, resulting in anti-inflammatory action
