Is diethyl phthalate soluble in water?

Diethyl phthalate (DEP) is a phthalate ester. It occurs as a colourless liquid without significant odour but has a bitter, disagreeable taste. It is more dense than water and insoluble in water; hence, it sinks in water.

How do you use diethyl phthalate?

Diethyl phthalate is currently used through direct addition in cosmetic products and indirectly in fragrances. The material is listed in the inventory of ingredients employed as a solvent and vehicle in fragrance and cosmetic products, as well as a denaturant, and film former.

What is dimethyl phthalate used for?

Dimethyl phthalate has many uses, including in solid rocket propellants, plastics, and insect repellants. Acute (short-term) exposure to dimethyl phthalate, via inhalation in humans and animals, results in irritation of the eyes, nose, and throat.

What is DEP in perfume?

Diethyl Phthalate (DEP) is a virtually odourless aromatic solvent. Whilst being a very efficient solvent it is also quite toxic. It is NOT restricted by IFRA. If used best use for non-skin contact products. It tends to depress perfume notes.

What does diethyl phthalate react with?

DIETHYL PHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions.

Is dimethyl phthalate toxic?

Human safety. Acute exposure to DMP via inhalation in humans and animals have shown to result in irritation to the eyes, nose and throat. Although some research has shown the association between the susceptibility of the reproductive system and phthalates esters, most phthalates demonstrate low acute toxicity.

Is dimethyl phthalate A insect repellent?

Insect repellents, e.g. against mosquitoes, ticks, fleas, such as DEET (diethyl toluamide), dimethyl phthalate. These are applied to the skin and repel insects principally by vaporisation.

Is phthalates soluble in water?

Phthalates with a higher molecular weight (HMW) are very slightly soluble in water; phthalates with a lower molecular weight (LMW) are reasonably soluble in water. Most common phthalate added to nail polish. Most widely-added phthalate to polyvinyl chloride (PVC) to make products flexible.

Is dibutyl phthalate liquid?

EPA has classified dibutyl phthalate as a Group D, not classifiable as to human carcinogenicity. N-butyl phthalate is a colorless oily liquid. It is insoluble in water. The primary hazard is the threat to the environment.

Is DEP oil Harmful?

Reproductive toxicity of DEP has been established in animal experimental models. Currently DEP is not considering as a potent toxic or a carcinogenic compound. However, it is a regulated compound which is considered as a potential hazard to human health and environment.

How is DEP oil made?

Diethyl phthalate is produced industrially by the reaction of phthalic anhydride with ethanol in the presence of concentrated sulfuric acid catalyst (Anonymous 1985; HSDB 1994).

Why are phthalates used in fragrances?

Phthalates used in fragrance oils, known as DEP (Diethyl Phthalate), are solvents used to extend the aromatic strength of the candle fragrance oil. DEP has been found to be non-toxic in skin products and candles if used at safe levels (IFRA – Background Paper – Phthalates – Final 12.2007).

Is diethyl phthalate toxic?

► Exposure to Diethyl Phthalate can cause headache, dizziness and nausea. causing numbness, “pins and needles,” and/or weakness in the hands and feet. NIOSH: The recommended airborne exposure limit (REL) is 5 mg/m3 averaged over a 10-hour workshift.
