Peptide Hair Composition for Cortex Penetration and Strengthening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hair treatment methods using harmful chemicals like sodium hydroxide, potassium hydroxide, and formaldehyde damage the hair fiber and scalp, while less damaging treatments are expensive or ineffective, and peptides struggle to penetrate and effectively interact with the hair cortex to improve mechanical properties.
Innovation Solution
A peptide composition with 11-12 amino acids, including 2-3 cysteines, is designed to penetrate the hair cortex, forming disulfide bonds and enhancing hair strength and hydrophobicity, using excipients suitable for dermatology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If harmful chemicals like sodium hydroxide, potassium hydroxide, and formaldehyde are used for hair treatment, then hair modeling effectiveness is improved, but hair fiber damage and scalp damage increase
Solution Approach 1:
The invention changes the chemical parameters by using peptides with specific amino acid sequences (11-12 amino acids, 2-3 cysteines) instead of traditional harsh chemicals. This parameter change allows effective hair treatment through disulfide bond formation without the damaging effects of strong alkalis and formaldehyde
Solution Approach 2:
The peptide composition acts as an intermediary substance that facilitates hair treatment by forming disulfide bonds with hair proteins. This intermediary approach replaces direct damage from harsh chemicals with a gentler molecular mediation process that achieves similar structural modification without the harmful side effects
2Object-affected harmful factors
If less damaging treatments are used to avoid harm to hair and scalp, then hair fiber damage is reduced, but treatment effectiveness decreases and cost increases
Solution Approach 1:
The invention optimizes the molecular parameters of the treatment agent by designing peptides with specific characteristics (11-12 amino acid length, 2-3 cysteine residues) that enable effective hair cortex penetration and disulfide bond formation, achieving high treatment effectiveness without the damage associated with traditional methods
3Strength
If peptides are used to treat hair, then hair strength is improved, but peptide penetration into hair cortex is difficult
Solution Approach 1:
The invention optimizes the physical parameters of the peptide molecules by controlling their size (11-12 amino acids) and chemical composition (2-3 cysteines), which enables effective penetration into the hair cortex while maintaining the ability to form strengthening disulfide bonds
Solution Approach 2:
The peptide composition is designed with pre-optimized molecular characteristics that facilitate cortex penetration before the actual treatment action occurs. The specific amino acid sequence and molecular size are predetermined to enable easy penetration, allowing the strengthening effect to occur without penetration resistance
