Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cosmetic compositions based on stem cell conditioned media have limited shelf-life and stability, particularly when stored at room temperature, and there is a need for products that are effective in skin rejuvenation and appearance improvement while maintaining long-term stability.

Innovation Solution

The cosmetic compositions are formulated as two separate components: a dried protein fraction from adipose-derived stem cell conditioned medium and a reconstitution medium, which are kept separate during storage and mixed just before use, using Tangential Flow Filtration to purify and formulate the protein fraction with cosmetic excipients, ensuring stability and potency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cosmetic compositions are formulated with stem cell conditioned media, then skin rejuvenation effectiveness is improved, but shelf-life and stability deteriorate

Engineering Contradiction:

Improveskin rejuvenation effectivenessVSAvoidshelf-life

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The cosmetic composition is divided into two separate components: a dried protein fraction component and a reconstitution medium component. These components are kept separate during storage to maintain stability, then combined before use to achieve the desired skin rejuvenation effect. This segmentation resolves the contradiction by allowing each component to be optimized independently for either stability or effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protein fraction is transformed from a liquid state (in conditioned media) to a dried solid state. This parameter change (from liquid to solid) dramatically improves storage stability and shelf-life while preserving the bioactive properties needed for skin rejuvenation when reconstituted with the appropriate medium.

2Ease of operation

If cosmetic compositions are stored at room temperature, then ease of storage is improved, but stability deteriorates

Engineering Contradiction:

Improveease of storageVSAvoidcomposition stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The protein fraction is dried to remove water, fundamentally changing its physical state and chemical stability. This allows the product to be stored at room temperature without degradation, eliminating the need for refrigeration while maintaining composition stability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The dried protein fraction is formulated as a stable, shelf-ready product that does not require complex storage conditions. The separate reconstitution medium is added only when needed, allowing the main active ingredient to remain in a stable, dried form during storage and transport.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Duration of action of stationary object

If protein fraction is purified and dried, then shelf-life is improved, but product complexity increases

Engineering Contradiction:

Improveshelf-lifeVSAvoidproduct formulation complexity

Core Design Contradiction:

Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The complex formulation is segmented into two separate components: the dried protein fraction and the reconstitution medium. This segmentation simplifies the formulation of each individual component while extending shelf-life, as the protein fraction can be purified and dried without concern for instability from other formulation ingredients.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protein fraction is pre-purified and pre-dried during manufacturing, completing the complex formulation work before storage. This preliminary action allows the product to be stored in a simple, stable dried state, with the full formulation complexity only realized when the consumer adds the reconstitution medium at home.

AI summary

Anti-aging cosmetic compositions prepared from conditioned medium of adipose-derived stem cells are provided. The cosmetic compositions are preferably ready-to-mix compositions, comprising two separate components: a protein component in a dried form that serves as the cosmetically active ingredient of the product, comprising a protein fraction purified from an adipose-derived stem cell conditioned medium; and a reconstitution component, for reconstituting the lyophilized protein component just before application to the skin.
