Skin Care Composition Starch Sunscreen Creaminess
Solution Overview
Problem
Many skin care compositions fail to provide desirable sensory sensations, particularly creaminess, due to the presence of certain ingredients, which negatively impact the application experience for consumers.
Innovation Solution
A skin care composition comprising starch, a benzotriazole derivative sunscreen, and a whitening pigment, with specific weight percentages of less than 2.2% for starch and less than 0.22% for the sunscreen, combined with a cosmetically acceptable carrier, to enhance creaminess perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If certain ingredients are included in the skin care composition, then the composition provides skin care benefits, but the sensory sensation (creaminess) deteriorates
Solution Approach 1:
The patent applies parameter changes by precisely controlling the concentration of starch (less than 2.2% by weight) and benzotriazole derivative sunscreen (less than 0.22% by weight) to resolve the contradiction between maintaining skin care benefits and improving sensory sensation. This quantitative optimization allows the composition to provide both functional benefits and desirable creaminess.
2Reliability
If starch and benzotriazole derivative sunscreen are used in higher concentrations, then skin care functionality is improved, but creaminess perception deteriorates
Solution Approach 1:
The patent optimizes the concentration parameters of key ingredients (starch < 2.2%, benzotriazole derivative sunscreen < 0.22%) to achieve the desired balance between skin care functionality and creaminess perception, demonstrating that precise parameter control can resolve this technical contradiction.
3Ease of operation
If ingredient concentrations are optimized for creaminess, then sensory sensation is improved, but skin care benefits may be reduced
Solution Approach 1:
The patent establishes optimal concentration ranges for starch and benzotriazole derivative sunscreen that simultaneously satisfy both sensory sensation requirements and skin care functionality, proving that parameter optimization can achieve dual benefits rather than trade-offs.
