Topical Cream Barrier Formation and Skin Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diaper rash creams fail to effectively absorb into the skin, spread instead of staying in place, leave a greasy residue, and are not effective against fungal and bacterial causes, while also being expensive and inaccessible in many regions, with current solutions not addressing the flora in excrement and causing skin irritation.
Innovation Solution
A natural, organic, antifungal, and antibacterial topical cream formulation using a combination of essential oils and aliphatic esters that forms a waterproof barrier on the skin, absorbing into the epidermis without residue, inhibiting bacterial and fungal growth, and providing superior moisturizing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petroleum based products such as petrolatum are used to create an impermeable barrier on the skin, then water repellency is improved, but absorption into the skin is limited and a greasy residue is left
Solution Approach 1:
The patent changes the chemical composition parameters by replacing petroleum-based products with natural oils and butters (coconut oil, shea butter, cocoa butter) that have different absorption properties. These natural fats are incorporated at specific concentrations (1-60% for oils, 1-30% for butters) to achieve both barrier formation and skin absorption without greasy residue.
Solution Approach 2:
The invention uses composite material formulation combining multiple natural ingredients: essential oils (tea tree, lavender, peppermint), natural oils, butters, and astringents (zinc oxide, titanium dioxide). This composite approach creates a synergistic effect where each component contributes different properties - some provide barrier function while others enhance absorption and reduce residue.
2Object-affected harmful factors
If amphoteric oxides such as zinc oxide or titanium oxide are used to absorb acidic components, then neutralization of acid is improved, but the product leaves a chalky white film and inhalation issues may occur
Solution Approach 1:
The patent modifies the concentration parameters of amphoteric oxides, using them at lower concentrations (1-30% for zinc oxide, 1-10% for titanium dioxide) compared to traditional high concentrations (10-40%). This parameter change reduces the chalky film formation while maintaining sufficient acid neutralization capability. The lower concentrations also minimize inhalation risks from powdered particles.
Solution Approach 2:
The invention introduces essential oils and natural butters as intermediary substances that carrier the amphoteric oxides and facilitate their uniform distribution and absorption. These intermediaries prevent direct contact between the oxide particles and the skin surface, reducing chalky film formation and inhalation risks while maintaining the acid-absorbing function.
3Quantity of substance
If high concentrations of amphoteric oxides are used to absorb all acid generated, then acid absorption capacity is improved, but the product becomes powdery and leaves residue
Solution Approach 1:
The patent creates a composite formulation where amphoteric oxides are combined with natural oils, butters, and essential oils. This composite structure transforms the powdery oxide into a non-powdery topical composition that forms a smooth barrier. The natural fats and oils act as binding agents that prevent the oxide particles from remaining powdery on the skin surface.
Solution Approach 2:
The invention changes the physical state parameters by incorporating amphoteric oxides into a lipid-based matrix (oils and butters). This transformation changes the oxide from a free-flowing powder to an integrated component of a semi-solid cream formulation, eliminating the powdery texture and residue while maintaining the acid absorption function at the specified concentrations.
4Reliability
If prescription antifungal medications such as Nystatin or miconazole nitrate are used to treat severe diaper rash, then antifungal effectiveness is improved, but cost increases significantly
Solution Approach 1:
The patent uses inexpensive natural essential oils (tea tree oil, lavender oil, peppermint oil) as the active antifungal and antibacterial agents. These natural oils are significantly cheaper than prescription antifungal medications like Nystatin or miconazole nitrate. The formulation uses these cheap natural ingredients at effective concentrations (1-10% for essential oils) to provide comparable therapeutic effect at a fraction of the cost.
Solution Approach 2:
The invention employs natural essential oils that possess inherent antifungal and antibacterial properties through their chemical composition (terpenes, phenols, and other bioactive compounds). These natural agents work autonomously without requiring prescription status or complex pharmaceutical manufacturing, making the product self-sufficient and accessible as an over-the-counter alternative to expensive prescriptions.
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 cream effectively prevents and treats moderate to severe diaper rash by forming a waterproof barrier that absorbs into the skin, eliminating fungal and bacterial causes without leaving a residue, thus reducing the need for artificial preservatives and expensive prescriptions, and is accessible as an over-the-counter option.
Implementation Method 1
having superior moisturizing and water repellency performance for the prevention and elimination of common and sever diaper rash
Implementation Method 2
absorbing into the epidermis without residue
Implementation Method 3
employ amphoteric oxides that are insoluble in water but soluble in most acids thereby absorbing the acidic components and pulling them away from the skin
