Transparent Bleaching Composition Segmentation for Hair Care
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent bleaching agents for keratin fibers face challenges in maintaining care properties without compromising transparency or bleaching performance, as care ingredients often impair transparency or weaken bleaching effectiveness.
Innovation Solution
A bleaching agent composition comprising two separately packaged preparations, where one contains persulfates and keratin hydrolyzate or silicone oil, and the other is a flowable mixture with natural polymers, allowing for enhanced care effects without affecting transparency and maintaining bleaching performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If care ingredients are added to transparent bleaching agents, then care properties are improved, but transparency is impaired
Solution Approach 1:
The bleaching agent is divided into two separately packaged preparations: (A) containing persulfate and care ingredients (keratin hydrolyzate and/or silicone oil), and (B) containing oxidizing agent and natural polymer. This segmentation allows care ingredients to be included without compromising the transparency of the oxidizing agent preparation (B), as care ingredients are concentrated in preparation (A) which is mixed immediately before use.
Solution Approach 2:
The patent specifies precise concentration ranges for care ingredients (0.1-6% by weight of keratin hydrolyzate and/or silicone oil in preparation A) and oxidizing agents (3-15% hydrogen peroxide, 1-5% persulfate in preparation B) to optimize both care properties and transparency. The natural polymer concentration (0.5-5%) is also controlled to maintain flowability and transparency while providing care effects.
2Reliability
If care ingredients are added to transparent bleaching agents, then care properties are improved, but bleaching performance is weakened
Solution Approach 1:
By separating care ingredients into preparation (A) and oxidizing agents into preparation (B), the patent ensures that care ingredients do not interfere with the bleaching action of hydrogen peroxide and persulfate. The mixed application mixture contains both care ingredients (0.1-6%) and oxidizing agents (3-15% H2O2, 1-5% persulfate) in optimized concentrations that maintain effective bleaching performance while providing care effects.
Solution Approach 2:
The patent creates a composite system combining oxidizing agents (hydrogen peroxide, persulfate), care ingredients (keratin hydrolyzate, silicone oil), and natural polymer (thickener) in specific concentration ranges. This composite formulation achieves synergistic effects where care ingredients protect the hair fiber while oxidizing agents provide lightening, and the natural polymer ensures proper consistency and transparency.
3Reliability
If multiple separately packaged preparations are used, then care properties are enhanced, but device complexity increases
Solution Approach 1:
The patent uses a two-preparation system (A and B) which is simple enough for consumer use but provides enhanced care properties through the inclusion of keratin hydrolyzate and silicone oil in preparation (A). The separate packaging allows each preparation to be optimized for its specific function while maintaining overall simplicity - preparation (A) is a powder and preparation (B) is a flowable liquid that mixes easily before application.
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 provides improved care properties for keratin fibers while maintaining transparency and enhancing bleaching performance, allowing for effective and controlled lightening of hair without damaging the fiber structure.
Implementation Method 1
The oxidizing agents contained in bleaching products are able to lighten the hair fiber through the oxidative destruction of the hair's own pigment melanin
Implementation Method 2
preparation (B) is flowable and contains at least one oxidizing agent, wherein preparation (B) and/or preparation (C) further contain/contains at least one natural polymer

AI summary
The present invention relates to compositions for lightening keratin fibres, comprising at least two preparations (A) and (B) separately packaged from one another, and optionally a further preparation (C) packaged separately from (A) and (B), which are mixed directly prior to application to give an application mixture, where preparation (A) comprises at least one persulfate, and preparation (B) is flowable and comprises at least one oxidising agent, and preparation (B) and/or preparation (C) further comprises/comprise at least one natural polymer, and preparation (A) comprises - based on its weight - a1) 0 to 3% by weight of keratin hydrolysate(s) and/or a2) 0 to 5% by weight of silicone oil(s), with the proviso that the preparation (A) comprises - based on its weight - 0.1 to 6 % by weight of compound(s) from the groups a1) and a2).
