1,3-Propanediol in Non-Aqueous Perfume Mixtures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The perfume industry faces challenges in enhancing pleasant olfactory aspects and reducing unpleasant odors in floral fragrances, with existing solutions often requiring large quantities of specific perfume oils that can be costly and impractical, and lacking in using naturally sourced, non-toxic, and stable ingredients.
Innovation Solution
A non-aqueous perfume mixture comprising >10% by weight of 1,3-propanediol combined with odorant alcohols, particularly those with green or floral notes, to emphasize pleasant notes and mask unpleasant notes like musty, greasy, or metallic odors, while being accessible, stable, and non-toxic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If specially developed perfume oils are used to mask unpleasant odors, then unpleasant odor impressions are reduced, but the perfume oil has its own very specific scent type which limits application versatility
Solution Approach 1:
1,3-propanediol serves as an intermediary substance that modifies the sensory properties of floral fragrances without imposing its own specific scent type. It acts as a mediator between the fragrance components and the human olfactory system, enhancing pleasant aspects and suppressing unpleasant ones while maintaining compatibility with various fragrance types.
Solution Approach 2:
The invention changes the sensory parameters of the fragrance by adding 1,3-propanediol, which modifies the olfactory profile by emphasizing fresh and floral notes while reducing musty, greasy, and metallic notes. This parameter change approach allows the same substance to work across different fragrance compositions without limiting versatility.
2Object-affected harmful factors
If large quantities of specific perfume oils are used to reduce unpleasant odors, then odor reduction effectiveness is improved, but cost and application practicality worsen
Solution Approach 1:
1,3-propanediol is a cost-effective alternative to specially developed perfume oils. It is a readily available, inexpensive substance that can be used in moderate quantities to achieve odor reduction, replacing expensive specialized perfume oils with a more economical solution.
Solution Approach 2:
1,3-propanediol serves multiple functions: it acts as a solvent, a sensory modifier, and an odor reduction agent. This multi-functionality allows it to replace multiple specialized substances, reducing the total quantity of substances needed while maintaining effectiveness.
3Object-affected harmful factors
If substances with appreciable odorous perfumery intensity are used for odor intensification, then pleasant odor intensity is enhanced, but the substance itself becomes perceptibly odorous which may interfere with the original fragrance profile
Solution Approach 1:
1,3-propanediol acts as a subtle intermediary that enhances the perception of pleasant odor notes without dominating the fragrance profile. Its low intrinsic odor intensity allows it to modify the sensory properties of floral fragrances without interfering with the original fragrance character.
Solution Approach 2:
The substance modifies the sensory parameters of the fragrance by enhancing the perception of fresh and floral notes rather than adding its own strong odor. This parameter modification approach intensifies pleasant odors without the interference that would result from using highly odorous substances.
