Acylproline Cosmetic Composition Odor Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Acylamino acid salts, such as acylproline salts, produce a peculiar odor when used in higher quantities or over time, which is not effectively masked by synthetic flavors, posing safety concerns for sensitive skin and affecting cosmetic appearance.
Innovation Solution
Combining acylproline or its salt with a zinc salt of pyrrolidone carboxylate and hydroxycarboxylic acid to reduce odor and prevent insoluble precipitate formation, resulting in a stable, transparent composition suitable for cosmetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blending amount of acylproline salt is increased to achieve moisturizing effect, then moisture retention property is improved, but peculiar odor becomes more pronounced
Solution Approach 1:
Zinc PCA is introduced as an intermediary substance that interacts with acylproline salt to suppress its peculiar odor. The zinc ion in Zinc PCA acts as a mediator that binds to the odor-causing components of acylproline salt, reducing the unpleasant smell while maintaining the moisturizing benefits of the acylproline salt.
Solution Approach 2:
The invention changes the chemical environment by introducing Zinc PCA, which alters the physical and chemical parameters of the composition. This parameter change suppresses the odor expression of acylproline salt without reducing its moisturizing functionality, allowing higher blending amounts to be used.
2Object-generated harmful factors
If synthetic flavor is added to mask the peculiar odor, then odor masking is achieved, but safety concerns arise for sensitive skin
Solution Approach 1:
Instead of masking the odor with potentially harmful synthetic flavors, the invention converts the harmful odor issue into a benefit by using Zinc PCA to actively suppress and reduce the peculiar odor at its source. This approach eliminates the need for synthetic flavor masking while maintaining safety for sensitive skin.
3Object-generated harmful factors
If Zinc PCA is combined with acylproline salt to reduce odor, then peculiar odor is suppressed, but insoluble precipitate is formed
Solution Approach 1:
The invention optimizes the concentration parameters of both Zinc PCA and acylproline salt to maintain solubility while achieving odor suppression. By carefully controlling the ratio and amounts of these components, the composition remains stable and transparent without forming precipitates.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively minimizes the peculiar odor of acylproline, maintains transparency, and provides a moisturizing effect, allowing for the production of cosmetics with superior appearance and skin hydration.
Implementation Method 1
Even though Zinc PCA is water-soluble, an insoluble precipitate is formed when combined with acyl proline or a salt thereof
