Probiotic Deodorant Composition Stabilized in Alcohol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deodorants often rely on non-living bacteria and may not effectively maintain a long-term viable population of odor-reducing bacteria on the skin, leading to temporary relief and potential increased odour issues upon discontinuation, and some ingredients may pose health risks.
Innovation Solution
A composition containing a stabilized, vital probiotic culture, encapsulated in oil and combined with alcohol, which maintains viability for months to years, promoting the growth of odor-reducing bacteria and inhibiting odor-producing bacteria, available as a spray deodorant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional deodorants are used to reduce bacteria in the armpit, then the number of bacteria is reduced and odour is eliminated temporarily, but upon discontinuation the bacteria population rebounds and odour returns worse than before
Solution Approach 1:
The probiotic deodorant enables the skin's microbiome to self-regulate by introducing beneficial bacteria that naturally compete with and suppress odour-producing bacteria. The live probiotic cultures (Lactobacillus and Bifidobacterium species) colonize the skin and continuously maintain balance without requiring external intervention, allowing the system to serve itself by establishing a self-sustaining beneficial bacterial population that prevents odour recurrence.
Solution Approach 2:
Probiotic bacteria act as intermediary organisms that mediate the interaction between the deodorant product and the skin's bacterial ecosystem. These live cultures serve as a bridge, introducing beneficial microbial species that compete with pathogenic bacteria for resources and space, thereby indirectly suppressing odour-producing bacteria without directly killing them. This intermediary approach creates a balanced microbiome that maintains long-term odour control.
2Object-generated harmful factors
If deodorants are applied continuously to maintain bacterial reduction, then odour control is maintained, but the complexity of use increases and health risks from continuous chemical exposure arise
Solution Approach 1:
The invention fundamentally changes the key parameter of the deodorant composition by incorporating live probiotic cultures instead of traditional antimicrobial chemicals. This parameter change transforms the mechanism of action from bacterial killing to bacterial competition and colonization. The probiotic formulation includes specific strains of Lactobacillus and Bifidobacterium along with prebiotics and postbiotics, creating a biologically active composition that establishes beneficial bacterial populations rather than merely suppressing bacteria temporarily.
Solution Approach 2:
The probiotic deodorant utilizes short-living probiotic cultures that are continuously replenished with each application. Rather than relying on persistent chemical agents, the formulation employs live bacteria with limited lifespan that naturally colonize the skin and are continuously replaced through regular application, creating a sustainable cycle of beneficial bacterial presence without long-term chemical accumulation.
3Ease of manufacture
If non-living bacteria are used in deodorants, then the composition is simple to manufacture, but the bacteria do not maintain viability and provide only temporary relief
Solution Approach 1:
The deodorant formulation employs a composite material structure combining multiple functional components: live probiotic cultures (Lactobacillus and Bifidobacterium species), prebiotics (oligosaccharides and inulin), postbiotics (bacterial metabolites), and conventional deodorant ingredients. This composite formulation creates a synergistic system where each component supports the viability and effectiveness of the probiotic cultures, enabling them to maintain activity throughout the product shelf life and upon skin application.
Solution Approach 2:
The formulation incorporates protective elements beforehand to cushion and protect the live probiotic cultures from environmental stressors during storage and application. Prebiotics are included to provide immediate nutritional support upon application, while postbiotics offer protective metabolites that enhance bacterial survival. This beforehand cushioning ensures the probiotics remain viable despite exposure to varying temperatures, humidity, and skin conditions.
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 composition effectively maintains a stable population of odor-reducing bacteria, providing long-term reduction in body odor and improving skin health without the need for continuous application and minimizing health risks associated with other deodorant ingredients.
Implementation Method 1
Bacteria that do not produce an odour, such as Staphylococcus epidermidis and Propionibacterium acnes, compete under normal circumstances with odour-producing bacteria, reduce them in number and thereby reduce the odour
Implementation Method 2
Probiotics applied locally to the skin may have a positive action due to competition with harmful microorganisms, may secrete useful metabolites, reduce the pH of the skin, or reinforce the barrier function of the skin against harmful external factors
Implementation Method 3
Probiotics applied locally to the skin may have a positive action due to competition with harmful microorganisms, may secrete useful metabolites, reduce the pH of the skin
