Cyclohexane-hexol and N-acyl amino acid composition for trypsin inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic solutions fail to effectively inhibit trypsin activity, leading to uneven skin tone and age spots due to unregulated melanin production and distribution, which are common issues in aging skin.
Innovation Solution
A topical cosmetic composition combining cyclohexane-1,2,3,4,5,6-hexol, N-acyl amino acids such as N-acyl Phenylalanine or N-acyl Tyrosine, and optionally vitamin B3 and 2-hexyldecan-1-ol, which inhibit trypsin activity when applied to the skin, thereby reducing melanin overproduction and improving skin tone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual cosmetic components are used, then the formulation is simple, but the trypsin inhibition effectiveness is insufficient
Solution Approach 1:
The patent combines multiple active ingredients (cyclohexane-1,2,3,4,5,6-hexol, N-acyl amino acid compounds, and optionally vitamin B3 and 2-hexyldecan-1-ol) into a single cosmetic composition. This combination creates a synergistic effect that enhances trypsin inhibition effectiveness compared to individual components, while the formulation remains practical for topical application.
Solution Approach 2:
The invention uses a composite cosmetic formulation incorporating multiple functional ingredients that work together to inhibit trypsin activity. The composite nature of the composition allows for enhanced biological activity and improved skin tone regulation while maintaining safety and tolerability through careful selection of complementary ingredients.
2Reliability
If trypsin activity is not inhibited, then the skin maintains natural functions, but melanin overproduction occurs leading to age spots and uneven skin tone
Solution Approach 1:
The patent targets the harmful effect of trypsin-induced melanin overproduction by using N-acyl amino acid compounds that inhibit trypsin activity. This conversion of a harmful biological process (excessive melanin production leading to age spots) into a beneficial outcome (regulated melanin distribution and uniform skin tone) is achieved through the selective inhibition of trypsin, which is known to activate PAR-2 receptors that promote melanosome transfer.
3Reliability
If strong trypsin inhibitors are used, then age spots are reduced effectively, but skin irritation may increase
Solution Approach 1:
The patent optimizes the concentration and formulation parameters of the active ingredients to achieve effective trypsin inhibition while minimizing skin irritation. By carefully controlling the amount of N-acyl amino acid compounds and cyclohexane-1,2,3,4,5,6-hexol in the composition, the formulation achieves therapeutic effectiveness without causing excessive skin irritation or adverse reactions.
Solution Approach 2:
The inclusion of vitamin B3 and 2-hexyldecan-1-ol as optional components may serve as intermediary substances that modulate the activity of the primary trypsin inhibitors. These additional ingredients can enhance the overall formulation's ability to inhibit trypsin while providing skin-conditioning benefits and reducing potential irritation, thereby serving as protective intermediaries between the active ingredients and the skin.
