Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal care vapor compositions for infants under 2 years of age face challenges in providing a high perception of vapor intensity while being safe for infant skin, avoiding greasy residue, and ensuring a mess-free application, due to limitations in fragrance levels and oil-based formulations.
Innovation Solution
A personal care vapor composition comprising a polyol component, emollient, olfactory component, and olfactory component fixative, with specific ratios and phases, allowing for a high perception of vapor intensity without irritation or greasy residue, and enabling mess-free application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the level of fragrance or essential oil is increased to deliver a high perception of vapor intensity, then the sensory experience and smell strength is improved, but the composition becomes irritating to infant skin causing pain and/or skin reddening
Solution Approach 1:
The patent changes the chemical parameters of the base composition by using a water-soluble polymer base instead of traditional oil-based or petrolatum-based bases. This allows for higher levels of olfactory components (fragrances and essential oils) to be incorporated without causing skin irritation, as the water-soluble base reduces the irritating effects while maintaining vapor intensity perception.
Solution Approach 2:
The patent creates a composite formulation combining water-soluble polymer base with specific olfactory components at elevated levels. This composite approach allows the beneficial vapor intensity of high fragrance levels to be achieved while the water-soluble base provides a non-irritating carrier system, resolving the contradiction between strength and safety.
2Stability of the object's composition
If oil or petrolatum-based chassis is used to disperse oils, then the olfactory composition is stable and solubilized, but the composition leaves greasy residue on skin, clothes and fabrics
Solution Approach 1:
The patent fundamentally changes the physical-chemical parameters of the base material from hydrophobic (oil/petrolatum-based) to hydrophilic (water-soluble polymer-based). This parameter change eliminates the greasy residue problem while maintaining the ability to solubilize and stabilize olfactory components through the polymer's solubilizing properties.
Solution Approach 2:
The patent substitutes the traditional oil-based dispersion mechanism with a water-soluble polymer solubilization mechanism. Instead of relying on oil-chassis to mechanically disperse essential oils, the water-soluble polymer base chemically solubilizes the olfactory components, providing stability without greasy residue.
3Object-generated harmful factors
If increasing water levels in compositions is done to improve aesthetics and reduce greasiness, then the composition becomes non-staining, but the perception of vapor intensity decreases
Solution Approach 1:
The patent uses a composite water-soluble polymer base that combines the benefits of water-based formulations (non-greasy, non-staining) with enhanced vapor delivery capabilities. The specific polymer structure and composition maintain olfactory component volatility and vapor intensity perception while providing the desired non-greasy aesthetics.
Solution Approach 2:
The patent optimizes the molecular weight and structural parameters of the water-soluble polymer to balance vapor intensity perception with non-greasy properties. By carefully selecting polymer parameters, the formulation achieves both high vapor perception and non-staining characteristics simultaneously.

AI summary
A personal care vapor composition, particularly useful for application to the skin of infants, is an emulsion of an oil phase and an aqueous phase. The aqueous phase includes one or more C3-C6 polyols. The oil phase includes an emollient selected from one or more triglycerides of C6-C18 fatty acids and isopropyl isostearate, an olfactory component comprising one or more essential oils, and an olfactory component fixative selected from the group consisting of amphiphilic terpene-based polyethers, Commiphora myrhha extract, methyl hydrogenated rosinate and mixtures thereof. The composition may be easily washed out of clothing that it contacts during use, and has a high perception of vapor intensity.
