Formic acid is characterized by its colorless liquid state and distinctive pungent odor. It is highly soluble in water and miscible with alcohol and ether. As the simplest member of the carboxylic acid family, formic acid consists of a hydrogen atom, a carbon atom, and two oxygen atoms, forming a carboxyl group (-COOH) attached to a hydrogen atom. This simplicity belies its reactivity and utility in multiple chemical reactions, including esterification, oxidation, and hydrogenation.

One of the appealing aspects of E325 is its safety for consumption. Sodium lactate is naturally present in various foods, including fermented products. Its production through fermentation processes aligns with consumers' increasing preference for natural ingredients in their diets. However, as with any food additive, moderation is key. Overconsumption of additives can lead to undesirable health effects, although sodium lactate is generally accepted as safe in typical dietary amounts.

Beyond the food industry, carrageenan has found applications in various other fields, including cosmetics, pharmaceuticals, and even biotechnology. In cosmetics, it is used as a thickener and emulsifier in creams and lotions, helping to improve product stability and texture. In pharmaceuticals, carrageenan acts as a binder and stabilizer in various formulations, enhancing the delivery and effectiveness of active ingredients.

In confectionery, E901 serves as a glazing agent, imparting a glossy finish to candies, chocolate, and baked goods. The wax enhances the aesthetic appeal of these products, making them more attractive to consumers while also providing a degree of protection against moisture and oxygen. Additionally, E901 is utilized in various dietary supplements and pills, where it serves as a coating agent to facilitate swallowing and protect the active ingredients within the capsule.

E472 is a food additive that encompasses several types of esters derived from fatty acids and glycerol. These esters are formed through the reaction of glycerol with fatty acids, primarily obtained from vegetable oils. The E472 category includes different subtypes, such as E472a (Glycerol esters of fatty acids), E472b (Glycerol mono- and di-esters of fatty acids), E472c (Glycerol acylate), and so on. These emulsifiers are recognized for their ability to improve the texture, stability, and shelf life of food products.

One noteworthy aspect of sodium benzoate is its environmental profile. As a biodegradable compound, it presents fewer environmental hazards compared to many synthetic preservatives. This characteristic aligns with the growing consumer demand for more natural and eco-friendly ingredients in food and cosmetic products.
