	Biocide / Cidal Agent		Biocides and cidal agents are functional chemicals that kill microbes, vegetation, insects and animal pests.
	Binding Agent		Binders and binding agents are additives, such as waxes, polyethylene glycol, or microcellulose, used to bind powders, fibers, or particulates into agglomerates, consolidated pellets, or compacts. The binders make the material easier to handle.
	Catalyst		Catalysts or initiators start, promote, or enable chemical reactions. Catalysts are not co-reactants and do not become part of the end-product.
	Crosslinker / Vulcanizer		Crosslinkers, vulcanizers, and vulcanizing agents are additives that enhance crosslinking, vulcanization, or bonding between polymer chains.
	Curing Agent ( Hardener / Curative)		Curative, curing, setting or hardening agents consist of catalysts, reaction initiators, co-reactants, crosslinking agents. When added to a polymer resin or adhesive, curing agents cause polymerization, which hardens the resin into solid plastic or elastomer form.
	Cloud Point Modifier		Chemical agents are used to modify the cloud point, the temperature at which surfactants or other chemicals become insoluble in water, resulting in a cloudy solution. The cloudiness occurs when micelle or molecular agglomerates of the surfactant form. Nonionic surfactants, waxes and oils can become cloudy as the temperature is raised. The cloudiness is due to the formation of micelles or molecular agglomerates. Higher salinity levels tend to increase cloud point temperature in some formulations. Cloud point control is useful in cleaners and detergents used with hot water.
	Clarifier		Clarifiers are added to liquids, plastic, elastomers, coatings, adhesives and other polymeric materials to increase transparency.
	Conditioner / Texture Modifier		Conditioners and texture modifiers improve the smoothness, body or consistency of the formulation or the substance (hair or clothing) onto which the formulation is applied. Conditioners may also have a healing or repair capacity.
	Coupling Agent		Coupling agents, such as silanes or zirconates, enhance the chemical bond between reinforcements, such as glass fibers and the plastic resin matrix. Coupling agents have SiO groups to bond to the inorganic filler, as well as functional groups that react with the resin system. Coupling agents are applied to the surface of the reinforcement or blended into the resin formulation. A sizing agent used on fiberglass yarns can consist of a mixture of coupling agents, lubricants, and binders.
	Corrosion Inhibitor / VCI		Chemical additives that inhibit corrosion or rust. Oil, wax, or grease-based additives work by blocking the access of moisture to a surface. Other agents may use a mechanism that absorbs or deactivates corrosive ions. Vapor phase corrosion inhibitors (VCI) form a corrosion-inhibiting atmosphere or vapor that forms a protective film on metal surfaces.

	Dispersing Agent / Deflocculant		Dispersing agents and deflocculants are used to suspend or disperse fine particles in a liquid or solution. Deflocculants break up agglomerated particles or flocs so that they can be more easily suspended or dispersed. Deflocculants are useful in forming colloids or suspensions. Usually, these additives create a charged layer on the surface of the particles, causing the particles to repel each other.
	Emulsifier		Emulsifiers have the ability to disperse oil droplets in water or a water-based fluid. They are also available for dispersing water droplets in oil or an oil-based fluid.
	Encapsulation / Delivery System		Encapsulation and delivery systems are used to introduce a drug into a patient and/or deliver the drug to the point of action.  Some drug delivery agents or systems may also provide prolonged or time controlled release mechanism. Encapsulation agents may protect the drug from degradation before delivery to the patient or to the site of action within the patient.
	Extender (Bulking Agent / Diluent)		Extenders, fillers or bulking agents are used to provide an inert fill in a product to increase volume and reduce costs without detracting from quality or performance. Diluents are inert, nonreactive liquids that act as diluting agents, carriers or bulking additives. Petroleum base stocks are common diluents or bulking additive in paints and pesticides.
	Film Former / Drying Aid		Film formers, coalescing agents and drying aids are used to aid in the formation of a coherent and dense polymer or organic coating/film during curing or drying processes.
	Flame / Fire Retardant		Flame-proofing agents, intumescent additives, and fire retardants are added to improve fire resistance.

	Herbicide / Defoliant		Herbicides, defoliants, and herbicidal agents kill and prevent the growth of plants or vegetation.
	Inhibitor		Chemical inhibitors suppress, decrease, or prevent reactions such as corrosion or electrochemical reactions, combustion or flame reactions (fire retardants), oxidation reaction, or biochemical reactions.
	Insecticide / Pesticide		Pesticides and insecticides kill and prevent the growth of insects and pests (rodent animals).
	Initiator		Initiators trigger chain reactions or polymerization processes. They can be part of the chemical process and become part of the end product. As the reaction proceeds, additional initiating units are created. Hardeners are co-reactant resins that initiate and become part of the end-structure or polymer.
	Impact Modifier / Toughening Agent		Impact modifiers or toughening agents are additives that increase the toughness or impact strength of a product. Toughness can be improved by increasing ductility or flexibility while maintaining tensile strength levels. For example, given two materials with the same tensile strength, the material with higher ductility (percentage elongation) has a greater toughness.
	Hardness / Strengthening Agent		Additives are used to increase the strength or hardness of a plastic, coating, or other material.
	Leveling Agent		Allow a coating or adhesive applied to a surface to flatten from gravitational forces, which eliminates height disparity, ripples, tracks, etc.
	Lubricity / Slip Agent		Lubricity or slip agents are lubricant additives that have been added in order to reduce friction and provide lubrication. Slip agents help improve scratch resistance by reducing friction. Slip agents can also provide anti-graffiti properties.
	Metal Removal / Precipitation (Water Softener)		Additives are designed or suitable for the removal of metal ions, usually through a precipitation mechanism.
	Oxidation Inhibitor / Anti-oxidant		Anti-oxidants are additives used to inhibit oxidation, a process which degrades many natural and organic products.

They corrode metals and form good electrolytes in battery applications. Strong acids can sting and burn the skin on contact.
	pH Modifier - Base		Bases or alkali compounds absorb hydronium ions in aqueous solutions, raising the pH level or increasing alkalinity. Alkali bases donate hydroxide ions to raise the pH. Base compounds provide a pH greater than 7 when added to water.
	pH Modifier - Buffer / Buffering Agent		Buffers consist of a weak acid or weak base. Buffers and buffering agents stabilize the pH of a product within narrow limits by regulating the concentrations of the acid and conjugate base.
	Propellant		Propellants are formulation additives used to dispense or aerosolize a product from a spray can or container.
	Reaction Terminator / Retarder		Reaction, set, or polymerization reaction terminators or retarders slow down or stop the progress of a reaction.
	Reaction Accelerator		Reaction, set, or polymerization reaction accelerators speed up the progress of a reaction.
	Reagent		Reagents are chemicals, dyes, enzymes, indicators, titrants, extractants, and other reaction solutions that participate in chemical reactions. Reagents can be the constituents required to synthesize a compound. A reagent can also be an analytical reactant to detect or measure the quantity of another chemical.  Reagents are typical used in laboratory settings.
	Release Agent (Anti-blocking / Anti-stick)		Release agents are added to a molding compound or applied to the surface of a mold to prevent the sticking of components in a mold. Antiblocking agents are used between paper sheets or plastic films to prevent sticking and provide release. Antiblocking agents typically consist of fine mineral or wax powders. Anti-graffiti or anti-stick additives also fall into this category.
	Rheology Modifier (Flow Agent)		Additives are used to control viscosity, rheology or flow characteristics of a product.
	Scale Inhibitor		Additives or chemical agents prevent or remove mineral scale formation. Scale inhibitors dissolve the mineral scale and tie up metal ions through a sequestration or chelation process.
	Settling Agent / Flocculant		Settling agents, coagulant, and flocculants  remove fine particles that are dispersed or suspended in a liquid or solution. The settling agent or flocculant causes fine particle to clump or coagulate together into larger agglomerates or flocs. The agglomerated particulates drop out of the suspension and fall to the bottom.
	Stabilizer / Antidegradant		Stabilizers and antidegradants are chemical agents used to stabilize or maintain specific functions or properties of a product or additives, especially additives used to enhance or stabilize chemical resistance, or prevent chemical degradation. Antidegradants prevent the product's feature or additive function from degrading over time or under certain environmental conditions, such as thermal degradation of a chemical.
	Stabilizer - Color		Additives are used to stabilize color or coloring additives, such as pigments, dyes, or intrinsic colorants.
	Stabilizer - Dimensional		Additives are used in plastics or elastomers to impart dimensional stability.
