Solution Overview

Problem

The value of exhausted Vetiver roots, which are typically discarded after steam distillation for essential oil production, is not utilized effectively in cosmetic compositions, limiting their potential application in skincare.

Innovation Solution

A cosmetic composition and method utilizing an aqueous extract of exhausted Vetiver roots, obtained through solvent extraction, which stimulates sebum secretion, improves skin lipid synthesis, and enhances skin hydration and barrier function, thereby adding value to previously discarded material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If steam distillation is used to extract essential oil from Vetiver roots, then essential oil is obtained, but the exhausted roots are discarded as waste

Engineering Contradiction:

Improveessential oil yieldVSAvoidexhausted roots waste

Core Design Contradiction:

Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent applies the principle of discarding and recovering by taking the exhausted Vetiver roots that would normally be discarded after steam distillation and recovering valuable components through solvent extraction. The process retrieves remaining aromatic compounds and other beneficial substances from the spent roots, transforming waste material into a useful cosmetic extract.

Inventive Principle:

Principle #34Discarding and recovering

Solution Approach 2:

The patent converts the harmful aspect of waste disposal into a beneficial resource. The exhausted roots, which represent loss and waste in traditional essential oil production, are transformed into a valuable cosmetic ingredient through extraction processes that recover remaining active compounds for use in skincare products.

Inventive Principle:

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

2Ease of manufacture

If exhausted Vetiver roots are discarded, then production cost is reduced, but potential cosmetic value is lost

Engineering Contradiction:

Improveproduction simplicityVSAvoidcosmetic active ingredient potential

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The patent applies universality by enabling the Vetiver roots to serve multiple functions. Instead of being limited to a single use in essential oil production where they become waste, the roots are now utilized for dual purposes: first for essential oil extraction via steam distillation, and then for cosmetic extract production through solvent extraction, maximizing the value of the raw material.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the extraction parameters from steam distillation conditions to solvent extraction conditions. By altering the extraction method and parameters, the patent accesses different components and properties of the Vetiver roots that are not obtainable through traditional distillation, thereby unlocking additional cosmetic value.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If Vetiver roots are used for essential oil production only, then oil quality is maintained, but cosmetic application potential is limited

Engineering Contradiction:

Improveessential oil qualityVSAvoidcosmetic composition versatility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies segmentation by separating the utilization of Vetiver roots into distinct stages and products. The first stage produces essential oil through steam distillation for traditional perfumery uses, while the second stage produces a separate cosmetic extract through solvent extraction. This segmentation allows each product to maintain its specific quality characteristics while expanding overall application versatility.

Inventive Principle:

Principle #1Segmentation
