Cosmetic Sunscreen Spray Reduces Textile Staining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sunscreens containing 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine suffer from poor solubility and a strong yellowish inherent color, leading to difficult removal from clothing and textiles, causing unsightly yellow discoloration.
Innovation Solution
A cosmetic emulsion formulation incorporating 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine in combination with propane/butane as a propellant, along with additional UV filters and emulsifiers, is developed to enhance solubility and reduce textile staining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine is used as a UV filter, then UV protection is improved, but solubility deteriorates and yellow staining increases
Solution Approach 1:
The patent changes the physical-chemical parameters of the formulation by incorporating specific emulsifiers and co-solvents that modify the solubility characteristics of the triazine filter. The formulation adjusts concentration parameters and phase composition to achieve better dissolution while maintaining UV protection efficacy.
2Reliability
If 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine is used as a UV filter, then UV protection is improved, but ease of operation deteriorates due to difficult removal from textiles
Solution Approach 1:
The patent introduces emulsifiers and surfactants as intermediary substances that facilitate the interaction between the hydrophobic triazine filter and the aqueous environment. These intermediaries reduce the affinity of the filter for textile fibers, enabling easier removal while preserving UV protection properties.
3Reliability
If 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine is used as a UV filter, then UV protection is improved, but object-generated harmful factors increase due to yellow staining
Solution Approach 1:
The patent employs color correction strategies by incorporating ingredients that counteract the yellow tint produced by the triazine filter. The formulation modifies the overall color profile to reduce visible yellow staining on light-colored textiles while maintaining the filter's UV absorption capabilities.
4Ease of operation
If aerosol spray formulation is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent utilizes aerosol technology by incorporating propane/butane propellants in compressed gas form. The pneumatic pressure system enables fine mist delivery of the sunscreen formulation, improving application convenience and uniform distribution while the self-contained can design manages the complexity of the delivery system.
