Solution Overview

Problem

Cosmetic compositions that improve skin hydration often cause an unsightly 'corrugated metal' effect, characterized by skin folds and wrinkles, and fail to provide a pleasant, silky texture and spreading behavior, particularly in fragile areas like the eye contour.

Innovation Solution

A cosmetic composition comprising glyceryl caprylate, 1,3-propanediol, and phytic acid or its salts, which reduces dehydration streaks and eliminates or minimizes the 'corrugated metal' effect while providing a pleasant, silky feel and suitable texture for skin application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If moisturizing cosmetic compositions are applied to improve skin hydration, then skin hydration is improved, but the 'corrugated metal' effect appears causing unsightly folds and wrinkles

Engineering Contradiction:
Improveskin hydrationVSAvoidcorrugated metal effect
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent modifies the chemical composition parameters by incorporating specific ingredients (glycerin, vegetable oils, plant extracts) at optimized concentrations to achieve hydration without the corrugated metal effect. The formulation adjusts the balance between humectants and emollients to prevent skin folding while maintaining moisture.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses a composite formulation combining multiple natural ingredients (glycerin, vegetable oils, plant extracts) that work synergistically to provide hydration while preventing the unwanted corrugated effect. This composite approach allows the composition to deliver moisture without causing skin folds.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If moisturizing cosmetic compositions are applied to improve skin hydration, then skin hydration is improved, but the texture and spreading behavior are unsatisfactory

Engineering Contradiction:
Improveskin hydrationVSAvoidtexture and spreading behavior
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent optimizes the viscosity and texture parameters by selecting specific vegetable oils and plant extracts that provide a pleasant, silky feel while maintaining good spreading behavior. The formulation adjusts the molecular weight and composition of ingredients to achieve optimal application characteristics.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If moisturizing cosmetic compositions are applied to improve skin hydration, then skin hydration is improved, but the skin feel is unpleasant

Engineering Contradiction:
Improveskin hydrationVSAvoidunpleasant skin feel
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The invention modifies the sensory properties by incorporating plant extracts and natural oils that provide a pleasant, non-greasy skin feel. The formulation adjusts the composition to eliminate unpleasant sensations while maintaining effective hydration.

Inventive Principle:
Principle #35Parameter changes
