#aditiv

• Additive — A chemical substance added in small quantities to a product (such as fuels, lubricants, foods, cement, or polymers) to improve its properties, prolong its preservation, or impart new structural characteristics; as an adjective, it describes a process based on accumulation, summation, or progressive addition (e.g., additive manufacturing). This structural element is indispensable in modern industrial processes for material performance optimization.
• Additived — Having been enhanced or treated through the addition of one or more additives; it refers specifically to fuels (gasoline, diesel) or industrial oils whose physico-chemical properties have been structurally optimized during the refining or packaging stage to ensure cleaner combustion or superior lubrication.
• Additivity — The property of certain quantities, functions, or systems to have a global value equal to the arithmetic sum of their individual component values. In a structural and mathematical sense, this phenomenon defines linear operators and extensive physical quantities (such as mass, volume, or energy), where the total effect of an assembly is obtained by the simple direct summation of partial effects, without distracting secondary interactions.
• Alastrin — A rare chemical term, commercial neologism, or niche active substance historically or experimentally used in organic synthesis or in formulating protective industrial compounds; a specific name attributed to a structural chemical compound (often a derived dye, a polymer additive, or a stabilizing agent). This word has an extremely restricted circulation, documented in technical patent indexes and laboratory glossaries of the last century.
• Ameliorant — Bringing an improvement; a substance, fertilizer, plant crop, or chemical compound added to a medium to optimize its physical, chemical, or biological properties. In soil science, it represents an amendment applied to degraded soils, while in baking it describes an additive used to enhance dough and finished product quality.
• Anti-knock agent — A chemical substance or additive added to fuels to increase their resistance to premature auto-ignition and to prevent the phenomenon of detonation in internal combustion engines; a compound that regulates the burning rate of the fuel mixture. As an adjective, it describes a fuel, mixture, or structural effect capable of ensuring a smooth and efficient engine operation, eliminating parasitic metallic knocks.
• Anti-icing fluid — Preventing or impeding the formation of ice; a liquid chemical substance (usually glycol or alcohol-based) sprayed on mechanical elements or added to fuel to lower the freezing point. As a noun, it designates the protective fluid utilized in preventative airport winter treatments.
• Antiol — A designation attributed to certain synthetic chemical compounds or structural additives with an antioxidant or protective role, capable of inhibiting the oxidative degradation of thiol (or alcohol) groups within biological or industrial macromolecules. In certain older biochemical and medical contexts, the term also designated some oily preparations for topical use intended for cellular protection or the neutralization of free radicals.
• Antioxidant — A chemical substance or molecular compound utilized to prevent, block, or slow down degradation and structural spoilage processes caused directly by the chemical action of molecular oxygen; a term used in engineering and the food industry as a functional synonym for autoxidation inhibitors of fats, oils, or polymers.
• Antifoaming agent — Preventing, reducing, or eliminating foam formation in various liquids during industrial, chemical, or culinary processes; a surface-active chemical or natural agent that lowers surface tension to break air bubbles. As a noun, it denotes an additive widely used in detergent production, wastewater treatment, the oil industry, or as a food ingredient to stabilize liquid textures.
• Flavoring agent — A chemical substance (natural, nature-identical, or synthetic) added to foodstuffs, beverages, cosmetics, or pharmaceuticals to impart, modify, or enhance flavor or scent. As an adjective, it characterizes an ingredient possessing flavoring properties.
