Solution Overview

Problem

Aqueous hydrogen peroxide compositions used in bleaching, dyeing, and permanent waving processes suffer from decomposition during storage, especially in warm climates or less than ideal conditions, leading to reduced performance over time.

Innovation Solution

An aqueous oxidizing composition with a pH of 1 to 6, containing hydrogen peroxide and orthodiphenols or imidazolidin-2,4-dione derivatives, along with optional additives like tiron and hydantoin, stabilizes hydrogen peroxide, maintaining performance over time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If hydrogen peroxide compositions are stored for extended periods, then shelf life increases, but decomposition increases and performance decreases

Engineering Contradiction:

Improveshelf lifeVSAvoidperformance consistency

Core Design Contradiction:

Duration of action of stationary objectVSReliability

Solution Approach 1:

The patent applies preliminary action by adding stabilizers (orthodiphenols or imidazolidin-2,4-dione derivatives) to the hydrogen peroxide composition before storage. These stabilizers preemptively prevent decomposition reactions from occurring during storage, allowing the composition to maintain its performance characteristics throughout the intended shelf life period.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The stabilizers act as intermediary substances that intervene between the hydrogen peroxide and the decomposition process. These compounds specifically inhibit the breakdown of hydrogen peroxide into water and oxygen, serving as mediators that protect the active ingredient from degrading while maintaining composition stability during storage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If storage temperature increases, then reaction rate increases, but decomposition rate increases and stability decreases

Engineering Contradiction:

Improvereaction rateVSAvoidcomposition stability

Core Design Contradiction:

SpeedVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary anti-action by incorporating stabilizers that specifically counteract the increased decomposition tendency at higher temperatures. These stabilizers are selected to maintain hydrogen peroxide stability across a temperature range (pH 1-6), preventing the temperature-accelerated decomposition that would otherwise occur during storage in warm climates or conditions.

Inventive Principle:

Principle #9Preliminary anti-action

3Stability of the object's composition

If pH is increased to improve stability, then decomposition resistance improves, but usability in cosmetic processes may be affected

Engineering Contradiction:

Improvedecomposition resistanceVSAvoidprocess compatibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by optimizing the pH range to 1-6, which represents a specific parameter window that balances two competing requirements: sufficient acidity to suppress hydrogen peroxide decomposition and maintain stability, while remaining compatible with subsequent cosmetic processing steps like bleaching, dyeing, and permanent waving that require different pH conditions. The stabilizers enable this pH optimization.

Inventive Principle:

Principle #35Parameter changes
