Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current perfume production processes struggle to meet increasing demand for high scent laundry detergents without significant capital investment, resulting in perfume particles with poor powder characteristics and flowability, especially in hot climates.
Innovation Solution
A process involving contacting a perfume ingredient with a molten material to form a pre-mix, then with solid materials to create a hardened-solid intermediate, followed by further processing to produce a perfume composition with a high perfume ingredient ratio, enhancing storage stability and flowability without requiring extensive equipment modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If perfume activity in perfume particles is increased to meet consumer demand for high scent laundry detergents, then perfume performance is improved, but powder characteristics and flowability deteriorate, especially in hot climates
Solution Approach 1:
The patent applies parameter changes by controlling the water content of the perfume particles within a specific range (0.5-5% w/w) and adjusting processing temperatures. By optimizing these parameters, the invention achieves high perfume activity while maintaining good powder characteristics and flowability, even in hot climates where temperatures exceed 30°C.
Solution Approach 2:
The invention uses composite materials by combining perfume ingredients with carrier materials to create perfume particles with optimized properties. The composite structure allows high perfume loading while maintaining desirable powder characteristics including flowability and stability in various environmental conditions.
2Productivity
If production capacity is increased to meet rising consumer demand, then productivity is improved, but capital cost and equipment complexity increase significantly
Solution Approach 1:
The patent applies universality by designing a multi-functional processing system that can handle multiple perfume formulations and production volumes using the same equipment. The process can be applied to existing perfume manufacturing equipment, allowing increased production capacity without requiring entirely new specialized equipment for each function.
Solution Approach 2:
The invention increases production capacity through parameter changes in the processing conditions, such as temperature, residence time, and material ratios, rather than through equipment expansion. This allows existing equipment to operate at higher capacities while maintaining product quality.
3Quantity of substance
If perfume particles are produced with high perfume ingredient content, then perfume performance is improved, but storage stability deteriorates and refrigerated transport becomes necessary
Solution Approach 1:
The patent achieves storage stability with high perfume ingredient content (greater than 10% w/w, preferably greater than 20% w/w) by controlling the water content parameter within 0.5-5% w/w and optimizing the perfume-to-carrier ratio. These parameter changes prevent degradation while maintaining high perfume activity without requiring refrigerated storage or transport.
Solution Approach 2:
The invention uses stable carrier materials that provide a protective matrix for the perfume ingredients, allowing high perfume content to be maintained in a stable form that does not require expensive refrigerated storage infrastructure.
