Chemical additives play vital roles in countless products we use daily, enhancing performance, safety, and shelf life. These substances undergo rigorous testing to ensure they meet strict quality and safety standards while providing tangible benefits to consumers.

Food Additives

Preservation and Safety

• Antimicrobial agents (e.g., sodium benzoate): Prevent spoilage in beverages and processed foods
• Antioxidants (e.g., ascorbic acid): Maintain freshness in oils and packaged snacks
• pH regulators (e.g., citric acid): Control acidity in jams and canned goods

Quality Enhancement

Emulsifiers (e.g., lecithin): Improve texture in chocolate and baked goods

Thickeners (e.g., xanthan gum): Create desired consistency in sauces and dressings

Anti-caking agents (e.g., silicon dioxide): Keep powders free-flowing

Household Product Additives

Cleaning Efficiency

• Surfactants: Enable detergents to lift grease and dirt
• Enzymes (e.g., proteases): Break down protein-based stains in laundry
• Bleach activators: Enhance stain removal at lower temperatures

Product Performance

• Corrosion inhibitors: Protect metal surfaces in appliances
• Fragrance compounds: Provide pleasant scents to cleaning products
• UV stabilizers: Prevent color fading in plastics

Personal Care Additives

Product Functionality

• Emollients (e.g., glycerin): Moisturize skin in lotions
• Preservatives (e.g., phenoxyethanol): Extend shelf life of cosmetics
• Thickening agents (e.g., carbomer): Create desired textures in shampoos

Safety and Comfort

• pH adjusters: Maintain skin-friendly acidity
• Chelating agents: Improve formula stability
• Sun protection factors: Shield against UV radiation
