Transformative Cosmetic Texture via Shear Thinning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic compositions with high levels of glycerin often result in a tacky and sticky feel upon application, which is undesirable for consumers, and existing solutions fail to provide a smooth, silky finish that is appealing for skin hydration and makeup compatibility.
Innovation Solution
A cosmetic composition comprising a non-ionic surfactant, a transformative agent with a specific butter to oil ratio of 2:5 to 9:10, a thickener, and a solvent, which imparts a transformative texture that thins from a thick application to a smooth satin or velvet finish, enhancing skin hydration and makeup compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high levels of glycerin are incorporated in cosmetic compositions, then skin hydration is improved, but the composition develops a tacky and sticky feel upon application
Solution Approach 1:
The patent changes the chemical composition parameters by replacing glycerin with a specific combination of humectants (sorbitol, propylene glycol, butylene glycol) and transforming the texture through the addition of silica particles and polymeric thickening agents. This parameter change maintains hydration efficacy while eliminating the tacky feel associated with high glycerin formulations.
Solution Approach 2:
The patent creates a composite material system combining multiple humectants (sorbitol, propylene glycol, butylene glycol) with silica particles and polymeric thickeners (carboxymethyl cellulose, hydroxyethyl cellulose). This composite approach achieves the hydration function of glycerin while the silica and polymer components provide a non-tacky, smooth application feel.
2Ease of operation
If light emollients or powders are used to reduce tackiness, then application feel is improved, but sufficient consumer appeal and residual tackiness reduction is not achieved
Solution Approach 1:
The patent achieves superior consumer appeal by optimizing the concentration parameters of multiple ingredients: sorbitol (5-20%), propylene glycol (5-20%), butylene glycol (5-20%), silica (0.1-5%), and polymeric thickeners (0.1-5%). This multi-parameter optimization creates a synergistic effect that delivers both excellent application feel and high consumer appeal, overcoming the limitations of single-ingredient approaches.
3Ease of operation
If a transformative texture is achieved through rubbing, then a silky/satin finish is provided, but the composition complexity increases
Solution Approach 1:
The patent exploits phase transition and rheological transformation: the composition maintains a stable, non-tacky state during application that transforms into a silky/satin finish upon rubbing and contact with skin. This transformation is achieved through the interaction of silica particles with the humectant-polymer matrix, which reorganizes under mechanical stress to create the desired finish.
Solution Approach 2:
The composition performs self-transformation upon application: the silica particles and polymeric thickeners automatically reorganize under the mechanical action of rubbing to create the silky finish, without requiring additional processing steps or complex delivery systems. The formulation itself provides the transformative effect through its inherent rheological properties.
Applied Scientific Principles
