Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing powders made of natural ingredients are messy due to their loose nature, causing them to fall over a wide area and contaminating surfaces and clothing.

Innovation Solution

Compositions that dry to a powder form, comprising starch, alcohol, water, and natural deodorant agents, with specific weight percentages of water exceeding starch and alcohol, and free of certain synthetic compounds, ensuring a clean application and adherence to the intended surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If loose powder is used for application, then the powdery feel is achieved, but the powder spreads over a wide area and contaminates surfaces and clothing

Engineering Contradiction:

Improvepowdery feelVSAvoidpowder spreading and contamination

Core Design Contradiction:

ShapeVSObject-generated harmful factors

Solution Approach 1:

The patent changes the physical state parameter of the composition by formulating it as a liquid or gel that dries to a powder. This allows the product to be applied in a controlled liquid form and then transforms into a dry powder finish, achieving the desired powdery feel without the mess of loose powder application

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The composition undergoes a phase transition from liquid/gel state during application to solid powder state after drying. This phase change enables controlled application in a non-powdery form while delivering the desired powdery sensory experience, eliminating the scattering problem of loose powders

Inventive Principle:

Principle #36Phase transitions

2Reliability

If natural ingredients are used in the composition, then the product safety and natural appeal are improved, but the formulation complexity increases

Engineering Contradiction:

Improveproduct safetyVSAvoidformulation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a composite formulation combining multiple natural ingredients including starches (arrowroot, tapioca), natural deodorant agents (methylheptylglycerin, Saccharomyces ferment filtrate), and natural preservatives. This composite approach achieves both safety through natural ingredients and functional performance by carefully selecting compatible components that work together

Inventive Principle:

Principle #40Composite materials

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The compositions provide a clean, powdery feel without spreading beyond the intended area, maintaining a powdered surface while using natural ingredients.

AI summary

Precision deodorant compositions are disclosed herein that are applied topically as a cream, a gel-crème, a gel, a lotion, or a serum and quickly dry to a powder. The compositions include a starch, an alcohol as a solvent, water, an emollient, and deodorant agent. The percent wt/wt of water is greater than the percent wt/wt of starch and is greater than the percent wt/wt of alcohol, and the emollient and deodorant agent are natural ingredients. The composition is substantially free of silicones, coconut oil, fractionated coconut oil, and phenoxyethanol.
