Solution Overview

Problem

Conventional cosmetic cleaning agents, such as shampoos, often damage hair and scalp due to the removal of lipids and proteins, and face challenges in maintaining foam properties and storage stability with the addition of care substances like oils and waxes, while also trying to minimize the use of surfactants and stabilizing agents for environmental efficiency.

Innovation Solution

A cosmetic cleaning agent formulation that includes anionic surfactants, cationic guar polymers, silicone emulsions with particles of a maximum 600 nm diameter, and waxes in a cosmetically acceptable carrier, optimizing the balance for gentle hair care and improved foam properties without excessive surfactant or stabilizer use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If care substances such as oils, fats and waxes are added to cleaning agents, then hair care properties are improved, but foam properties and storage stability deteriorate

Engineering Contradiction:

Improvehair care propertiesVSAvoidfoam properties and storage stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses specific cationic polymers (polyquaternium-10, polyquaternium-7) as intermediary substances that mediate between the anionic surfactants and care substances (oils, fats, waxes). These cationic polymers interact with both the anionic surfactants and the care substances, stabilizing the formulation and preventing deterioration of foam properties and storage stability while maintaining improved hair care properties.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite formulation system combining anionic surfactants, cationic polymers, and care substances (oils, fats, waxes) in specific proportions. This composite approach allows the different components to work synergistically, where the cationic polymers act as binding agents that hold the care substances within the surfactant system, maintaining both stability and care effectiveness.

Inventive Principle:

Principle #40Composite materials

2Stability of the object's composition

If larger amounts of surfactants and stabilizing agents are used, then foam properties and stability are improved, but resource efficiency deteriorates

Engineering Contradiction:

Improvefoam properties and stabilityVSAvoidresource efficiency

Core Design Contradiction:

Stability of the object's compositionVSLoss of substance

Solution Approach 1:

The patent optimizes the concentration parameters of all components in the formulation. Instead of using large amounts of surfactants and stabilizers, the patent uses specific optimized concentrations: 0.1-10% anionic surfactant, 0.01-1% cationic polymer, and 0.1-5% care substances. This parameter optimization achieves stable foam properties and storage stability while minimizing resource consumption and maximizing efficiency.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If conventional cleaning agents are used, then cleaning effectiveness is maintained, but hair and scalp are damaged due to removal of lipids and proteins

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidhair and scalp damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the potentially harmful effect of surfactants (which can strip lipids and proteins) into a beneficial effect by adding care substances (oils, fats, waxes) that replenish and protect these components. The cationic polymers facilitate this by binding the care substances to the hair, ensuring that the cleaning process simultaneously provides conditioning and protection, transforming the harmful lipid removal into a beneficial lipid replenishment effect.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
