Solution Overview

Problem

Customizing cosmetic compositions for individual consumers is challenging due to the time required to create personalized products and the potential waste associated with producing bespoke formulas tailored to a single consumer's unique skin needs.

Innovation Solution

A cosmetic composition precursor is developed, comprising partially neutralized fatty acid and high HLB surfactant, which can be rapidly hydrated with water or a water-miscible solvent to create a customizable end-use composition, allowing for on-demand production and reduced waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cosmetic compositions are customized for individual consumers, then the product meets individual skin needs, but the production time and waste increase

Engineering Contradiction:
Improvecustomization for individual skin needsVSAvoidproduction time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The cosmetic composition is divided into two segments: a stable precursor formulation containing partially neutralized fatty acids and active ingredients, and a hydration step that converts it to final use form. This segmentation allows the precursor to be manufactured once and stored, then rapidly converted to multiple customized formulations by adding different amounts of water or water-miscible solvents, reducing both production time and waste.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The precursor formulation is prepared in advance with partially neutralized fatty acids (30-70% neutralization) and high HLB surfactants, creating a stable base that can be rapidly hydrated later. This preliminary action separates the complex formulation work from the final customization step, allowing quick adaptation to individual consumer needs without repeating the entire formulation process.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If cosmetic compositions are customized for individual consumers, then the product meets individual skin needs, but the material waste increases

Engineering Contradiction:
Improvecustomization for individual skin needsVSAvoidmaterial waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The precursor formulation allows customization through parameter changes - specifically, varying the amount of water or water-miscible solvent added to the fixed precursor base. This enables multiple customized formulations from a single precursor composition, reducing material waste by eliminating the need to manufacture separate batches for different consumer needs.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The precursor formulation serves multiple functions: it acts as a stable base formulation, a storage form, and a versatile platform for creating multiple customized end products. By making the precursor multi-functional, the invention reduces waste as the same precursor can be used to create various customized compositions for different skin types and needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If traditional cosmetic formulations are used, then the product is stable, but the customization and on-demand production capability is limited

Engineering Contradiction:
Improveformulation stabilityVSAvoidcustomization capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The invention creates a dynamic system where the precursor formulation can be statically stored with partial neutralization (30-70%), then dynamically converted to the final hydrated form on-demand. The partially neutralized state provides stability during storage, while the addition of water or water-miscible solvents triggers rapid hydration and activation of the active ingredients, enabling customization without compromising stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The precursor-to-final-product conversion utilizes a phase transition approach: the precursor exists in a stable, low-water state suitable for storage and shipping, then undergoes a hydration phase transition when water or water-miscible solvent is added. This phase change activates the formulation and enables customization while maintaining stability during the transition and in the final product.

Inventive Principle:
Principle #36Phase transitions
