Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chlorine bleach products do not offer excellent performance across a wide range of criteria such as formulation flexibility, odor, stability, and moisture sensitivity, making them unsuitable for various applications.
Innovation Solution
Development of intercalated bleach compositions with a specific formula M x (OCl) y (O) m (OH) n, where M is an alkaline earth metal like magnesium or calcium, and a molar ratio of alkaline earth metal to hypochlorite of at least 3:1, which exhibit improved stability, reduced odor, and pH buffering characteristics, allowing for controlled hypochlorite release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional chlorine bleach products are used, then cleaning and bleaching effectiveness is achieved, but formulation flexibility and odor characteristics deteriorate
Solution Approach 1:
The patent changes the chemical parameters of the bleach composition by using magnesium or calcium hypochlorite with specific molar ratios (Mg:OCl ≥ 3:1 or Ca:OCl ≥ 3:1) and controlling pH within 7-11. This parameter optimization enables better formulation flexibility while maintaining cleaning effectiveness, resolving the contradiction between reliability and adaptability.
2Illumination intensity
If sodium hypochlorite phosphate adduct is used, then solution clarity is improved, but compatibility with certain applications deteriorates due to phosphate content
Solution Approach 1:
The patent extracts and eliminates phosphates from the bleach formulation by using magnesium or calcium hypochlorite instead of sodium hypochlorite phosphate adduct. This removal of harmful phosphates maintains solution clarity while improving application compatibility, especially for laundry detergents and other phosphate-sensitive applications.
3Quantity of substance
If existing bleach products are used, then chlorine availability is achieved, but stability and moisture sensitivity deteriorate
Solution Approach 1:
The patent optimizes the chemical parameters by using magnesium or calcium hypochlorite with controlled molar ratios and pH levels (7-11), which significantly improves stability and reduces moisture sensitivity while maintaining chlorine availability. The specific parameter control prevents degradation and enhances shelf life.
4Power
If high concentrations of hypochlorite are used, then cleaning power is increased, but pH buffering capacity and stability deteriorate
Solution Approach 1:
The patent changes the pH parameter to within the range of 7-11, which provides adequate pH buffering capacity while maintaining high cleaning power. This parameter optimization allows the bleach to effectively clean without excessive pH levels that would cause instability and degradation.

AI summary
The invention relates to compositions, methods of use, and methods of manufacture for an intercalated bleach compound and compositions thereof. The intercalated bleach compound has the formula Mx(OCl)y(O)m(OH)n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3: 1. In other words, x is ≥ 3y. The compounds exhibit excellent stability, little or no chlorine bleach odor, exhibit excellent pH buffering characteristics, and less reactivity with organic materials as compared to alternative chlorine bleach products.
