Remediant Chemistry for Peroxide Control in Perfumery and Food Raw Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Formulated perfumes, body care products, homecare products, essential oils, food raw materials, and natural extracts undergo oxidation, leading to the formation of harmful chemical species that alter organoleptic properties or cause skin irritation and rancidity, exceeding regulatory limits and failing quality control testing.
Innovation Solution
The addition of remediants such as α-oxocarboxylic acids, inorganic salts, thiols, and sulfur-containing peptides to these formulations to reduce and inhibit oxidation, thereby stabilizing the products and preventing skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perfumery raw materials, formulated perfumes, body care products, home care products, essential oils, food raw materials, and natural extracts are stored or used under normal conditions, then they undergo oxidation resulting in the formation of harmful chemical species including peroxides, organic hydroperoxides, and transesterification products, but this oxidation alters organoleptic properties, causes skin irritation, and leads to failure of quality control testing
Solution Approach 1:
The patent employs antioxidants as intermediary substances that intervene in the oxidation process. These antioxidants (such as vitamin E, vitamin C, BHT, and other compounds listed in the specification) act as mediators between oxygen and the susceptible raw materials, donating electrons to free radicals and preventing chain oxidation reactions. This intermediary action protects the perfumery and food raw materials from oxidation damage while maintaining product quality and safety
Solution Approach 2:
The patent employs various strategies to create an inert or low-oxygen environment for susceptible raw materials. This includes using nitrogen or argon atmospheres during storage and processing, vacuum packaging, and incorporating oxygen-scavenging antioxidants that actively remove dissolved oxygen from the product matrix. By reducing oxygen availability, these methods prevent oxidation reactions while maintaining product integrity
2Object-affected harmful factors
If the peroxide value (POV) is reduced to meet regulatory limits and prevent skin sensitization issues such as contact dermatitis, then product safety improves, but additional processing steps and remediant additions are required
Solution Approach 1:
The patent implements preliminary antioxidant protection measures during the formulation and manufacturing stages. Antioxidants are incorporated into raw materials and finished products before oxidation can occur, preventing peroxide formation rather than treating it afterward. This proactive approach includes selecting raw materials with inherent antioxidant properties and adding protective agents during manufacturing, thereby reducing POV and skin sensitization risk without requiring complex post-processing steps
Solution Approach 2:
The patent utilizes natural antioxidants that are already present in many perfumery and food raw materials, such as phenolic compounds in essential oils, vitamin E in plant extracts, and other endogenous protective agents. By harnessing these self-service antioxidant systems inherent to the materials themselves, the patent reduces reliance on external additives and complex processing while still achieving effective POV control and skin safety
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 method effectively reduces peroxide value (POV), enhancing stability and shelf life while preventing skin irritation and rancidity, meeting regulatory standards.
Implementation Method 1
The peroxides and hydroperoxides may be reacted with a remediant such as, for example, an α-oxocarboxylic acid, an organic ammonium salt of the α-oxocarboxylic acid, an inorganic salt of the α-oxocarboxylic acid, a thiol, sulphur-containing peptides, sulphur-containing proteins, phosphorylated ascorbic acid analogues, ascorbate esters, ascorbic acid salts, oxalic acid monoesters, oxalic acid monoester salts, silane hydride compounds, diesters of oxaloacetic acid, salts of diesters of oxaloacetic acid, glyoxylic acid, and salts of glyoxylic acid
Implementation Method 2
Many formulated perfumes, body care products, home care products, perfumery raw materials (such as, for example, essential oils, natural extracts, and synthetic ingredients), and food raw materials (such as, for example, fats and oils derived from animal or plant sources, and derivatives thereof) can undergo oxidation, resulting in the formation of chemical species including peroxides, organic hydroperoxides
