Concentrated Cosmetic Serum with High Contact Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic compositions face challenges in delivering high levels of moisturization and anti-aging benefits while avoiding tackiness and skin irritation, as high concentrations of humectants like glycerin result in undesirable aesthetics and potential skin issues.
Innovation Solution
A concentrated aqueous cosmetic composition with at least 20% water and high levels of humectants (4.5% by weight) and skin benefit actives such as peptides, tyrosinase inhibitors, vitamin B3, and pigments, which maintains tackiness for targeted application to provide prolonged benefits without migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of humectants like glycerin are used to provide moisturisation benefits, then moisturisation effectiveness is improved, but the composition develops poor aesthetics with sticky and tacky feel
Solution Approach 1:
The patent changes the concentration parameter of humectants to a moderate level (4.5% glycerin) rather than high concentration, and combines it with high concentrations of skin benefit actives (8% peptides, 5% vitamin B3, 3% tyrosinase inhibitor). This parameter adjustment resolves the contradiction by achieving moisturisation effectiveness without the excessive stickiness and tackiness that occurs at higher humectant levels.
2Reliability
If high concentrations of skin benefit actives are incorporated to deliver anti-ageing benefits, then anti-ageing effectiveness is improved, but the composition has limited space for additional actives and may cause skin irritation
Solution Approach 1:
The patent applies local quality by concentrating specific skin benefit actives at high levels in targeted areas of the formulation - peptides at 8%, vitamin B3 at 5%, and tyrosinase inhibitor at 3%. This allows high anti-ageing effectiveness in specific functional areas while maintaining overall formulation balance and flexibility for additional ingredients.
3Reliability
If high levels of humectant are used to ensure moisturisation, then skin hydration is improved, but the composition leaves skin feeling greasy and tacky
Solution Approach 1:
The patent creates a composite formulation combining moderate levels of humectants (4.5% glycerin) with high levels of skin benefit actives (peptides, vitamin B3, tyrosinase inhibitor) and supporting ingredients. This composite approach achieves skin hydration benefits while the diverse ingredient composition prevents the greasy and tacky feel associated with high humectant formulations alone.
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 delivers anti-aging benefits by maintaining a high contact angle on the skin, reducing migration, and providing prolonged action in targeted areas, while the tackiness is intentionally maintained for direct application benefits and lost when added to other products.
Implementation Method 1
comprising a) at least 4.5% by weight of the composition of humectant
Implementation Method 2
maintaining a high contact angle on the skin, reducing migration, and providing prolonged action in targeted areas
