Dissolvable Deodorant Patch for Portable Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deodorant dispensing methods are not portable, economical, or convenient for single-use application, lacking an effective solution for immediate and efficient delivery of deodorant for underarm hygiene.
Innovation Solution
A deodorant patch with a thickness of 15 micrometers to 150 micrometers, suitable for underarm placement, dissolving within 3 to 5 seconds at body temperature, and constructed with a top and bottom carrier sheet for adhesive attachment, containing aluminum zirconium tetrachlorohydrex GLY and other active ingredients for odor control and antiperspirant properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional deodorant dispensing methods (roll-on, aerosol, stick, gel, cream) are used, then deodorant material can be applied effectively, but the product is not portable and requires multiple uses from a single container lasting several days or weeks
Solution Approach 1:
The patent applies the disposable principle by creating a single-use deodorant patch that is discarded after one application. The patch is made from a soluble polymer matrix containing deodorant active ingredients, designed to be applied once and then disposed of, eliminating the need for reusable containers and mechanisms.
Solution Approach 2:
The patent changes the physical state and delivery parameters of deodorant by transitioning from conventional semi-solid or liquid forms in containers to a solid dissolving patch form. The patch dissolves in body temperature water to release active ingredients, fundamentally changing how deodorant is delivered and applied.
2Productivity
If a single-use deodorant patch is designed to dissolve quickly (3-5 seconds at body temperature), then immediate odor control is achieved, but the patch must be made from specially soluble materials requiring precise temperature control
Solution Approach 1:
The patent changes the solubility parameters of the polymer matrix by selecting specific polymer types and adding plasticizers that enable dissolution at body temperature (37°C). The formulation is designed to dissolve completely within 3-5 seconds upon contact with body temperature water, achieving rapid odor control.
Solution Approach 2:
The patent uses composite materials combining a soluble polymer matrix (such as polyvinyl alcohol, carboxymethyl cellulose, or starch) with deodorant active ingredients and plasticizers. This composite formulation enables controlled dissolution at body temperature while maintaining structural integrity during application.
3Ease of operation
If the deodorant patch is made thin (15-150 micrometers) for comfortable underarm placement, then comfort and flexibility are improved, but the patch may lack sufficient adhesive strength and structural integrity
Solution Approach 1:
The patent applies thin film technology by forming the deodorant patch from a soluble polymer matrix with controlled thickness (15-150 micrometers). The thin film structure provides comfort against the skin while the adhesive layer integrated into the formulation ensures sufficient bonding strength to remain in place during application.
Solution Approach 2:
The patent uses composite materials combining the soluble polymer matrix with adhesive agents and plasticizers to achieve the right balance between thinness for comfort and sufficient adhesive strength. The composite formulation allows the patch to be thin enough for comfort while maintaining adequate bonding properties.
4Ease of operation
If the deodorant patch is designed for single-use application, then portability and convenience are maximized, but the economic value per use is reduced compared to reusable containers
Solution Approach 1:
The patent accepts the economic trade-off of disposable single-use patches, which eliminate the need for reusable containers, mechanisms, and cleaning. While each patch contains a limited amount of deodorant, the convenience and portability benefits outweigh the reduced material efficiency, especially for travel and on-the-go use.
Solution Approach 2:
The patent segments the deodorant supply into individual single-use patches rather than a single reusable container. Each patch is a discrete unit containing a specific amount of deodorant active ingredients, designed for one-time application and then discarded, simplifying the user experience and improving portability.
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
Provides immediate and efficient odor control, antiperspirant functionality, and convenience as a portable, single-use product that dissolves quickly upon skin contact, maintaining personal freshness and being flexible and adaptable for various shapes and sizes.
Implementation Method 1
The patch may be constructed where the deodorant dissolves following skin contact with a user. The deodorant may dissolve in under or less than ten minutes or desirably 3 to 5 seconds at a temperature between about 33.3 degrees C. and about 37.8 degrees C.

AI summary
This invention relates generally to an underarm hygiene product having the form of a deodorant patch between a top carrier sheet and a bottom carrier sheet. Deodorant patches dissolve upon contact with the underarm skin and provide a discreet, portable method of remaining fresh in any time or place. Convenient one time dispensing by a flat patch eliminates the need for bulky containers and provides an elegant solution to limitations on quantities of personal care products during airline flights while away from home. This invention also relates to a method of producing the underarm hygiene product.
