The mandated pesticide label contains a number of specified items, including the concentration and/or percentage of both the active (A.I.) and inert ingredients proper mixing of the formulation with water to obtain the application rate of A.I., what the A.I. 

Numerous nonplasticizer uses of DEHP have been reported. However, it is not clear to what extent these uses arc, or have ever been, important. These include 1he use of DEHP as a solvent in erasable ink, as an acaracide in orchards, as an inert ingredient in pesticide products, in cosmetics, in vacuum pump oil, as a component of dielectric fluids in electrical capacitors, to detect leaks in respirators, and for use in testing of air filtration systems (HSDB 1990 Mannsville Chemical Products Corporation 1990 NTP 1989). 

Surfactants are used primarily as inert ingredients of pesticides, especially in agricultural applications. These surfactants usually have TSCA as well as inert pesticidal regulatory status in the US. Some surfactants are active components in pesticides. For example, the cationic surfactants benzalkonium chloride and didecyl ammonium chloride and their various derivatives are registered as active ingredients in disinfectant products with many household and industrial applications. 

The information provided must include all the facts known about the pesticide except, possibly, the identity of inert ingredients in the formulation. These facts include the chemistry, biochemistry, and toxicology of the pesticide data gathered in the evaluation... 

The components of pesticide products which have pesticidial activity are called active ingredients. A particular product may contain more than one active ingredient. Active ingredients are rarely used applied in their pure form. Instead, they are normally mixed with inert (inactive) ingredients so that you can handle them more conveniently and safely and apply them more easily and efficiently. This mixture of active and inert ingredients is called a pesticide formulation. The final pesticide formulation is ready for use, either as packaged or after dilution with solvents (e.g., water or petroleum) or other carriers (e.g., silica or silicates). 

The range of pesticide formulations routinely used in agricultural situations complicates the selection of appropriate PPE. Pesticide form, toxicity, concentration, and additives and inert ingredients are primary considerations in planning clothing strategies. 

Another variation among formulations of agricultural pesticides is the plethora of additives and "inert" ingredients added to the active ingredients to create each formulation. These ingredients may contribute to the exposure risk... 

On most labels you ll also find the words inert ingredients, a catchall term for additives that make pesticides easier to use. Inert ingredients do not enhance a product s toxicity. Rather, they are nonreactive substances thoi... 

Inert ingredients in liquid pesticides include water, alcohol, and other solvents. Pesticide powders and dusts often contain added diatomaceous earth, powdered seeds, or talc for added bulk, or fuller s earth to help prevent caking. Other inert ingredients, known as surfactants, help powders mix easily with water or help sprays adhere to foliage so that pests are more likely to contact it. In the absence of surfactants, many pesticide sprays would simply roll off waxy leaf surfaces. Soap is one of the most common surfactants added to pesticide sprays. 

In 1987, the US EPA instituted a policy (52 FR 13305, Inert Ingredients in Pesticide Products) to reduce the potential for adverse effects from pesticide products containing toxic inert ingredients. This policy established data requirements for new inert ingredients and categorized inert ingredients into four lists (Table 1).
