Perfume Raw Materials for Harsh Acid Odor Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer products containing harsh acids, such as phosphoric acid or formic acid, emit odors that negatively impact the trigeminal nerve, making it challenging to neutralize these odors effectively with traditional perfume ingredients, as they often compete rather than neutralize the harsh scent.
Innovation Solution
The use of specific perfume raw materials and combinations, listed in Tables 1 and 2, which are independent of odor intensity, are capable of neutralizing harsh odors impacting the trigeminal nerve, when incorporated into consumer products or perfume delivery systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional perfume ingredients with strong intensity are employed to counter the harsh odour, then the odour masking capability is improved, but the original harsh odour remains clearly noticeable because the ingredients merely compete rather than neutralize
Solution Approach 1:
The patent changes the chemical parameters of the perfume composition by incorporating specific ingredients (ammonia, amine salts, or alcohols with 5 or more carbon atoms) that fundamentally alter how the fragrance interacts with the harsh odour. Instead of using traditional masking agents that compete with the odour, these specific parameters enable actual neutralization through chemical interaction, thereby resolving the contradiction between masking capability and neutralization effectiveness
Solution Approach 2:
The patent introduces intermediary substances (ammonia, amine salts, or long-chain alcohols) that act as mediators between the harsh odour and the consumer's perception. These intermediaries chemically interact with the harsh odour molecules to neutralize them, rather than simply competing for attention. This intermediary approach enables effective neutralization while maintaining pleasant fragrance characteristics
2Ease of manufacture
If acids are used in consumer products to remove deposits such as lime scale, then the cleaning effectiveness is improved, but a harsh odour is generated that negatively impacts the trigeminal nerve
Solution Approach 1:
The patent converts the harmful harsh odour generated by cleaning acids into a benefit by using specific perfume ingredients (ammonia, amine salts, or long-chain alcohols) that chemically neutralize the acid vapours. The harmful acid odour is transformed into a neutral or pleasant fragrance experience, allowing the cleaning product to maintain its effective acid content while eliminating the sensory harm to consumers
Solution Approach 2:
The patent introduces intermediary substances (ammonia, amine salts, or alcohols with 5 or more carbon atoms) that act as chemical mediators between the cleaning acids and the consumer's sensory system. These intermediaries react with the acid vapours to neutralize them, preventing direct interaction with the trigeminal nerve while preserving the cleaning functionality of the acid-based formulation
