Perfume oils

If the new niche for the perfume is its use in cosmetics, toiletries or household product, then the niche-product interaction becomes very important. Perfumes are used specifically for their odor whereas in these new niches several new factors must be considered. For example, the perfume oil used in creams must not cause discoloration the fragrance used in a powdered detergent must be alkali resistant a fabric softener is expected to leave clothes with a pleasant odor and even a household cleanser must have a pleasant and functional odor, although active chlorine places difficulty on the stability of the perfume oil. Of course, decisions can affect or modify the product (perfume) or the niche (e.g. creams). 

C12H22O, Mr 182.30, 25 0.861-0.870, ng 1.453-1.461, a colorless to slightly yellow liquid with a complex wood floral note with amber and violet nuances. It is used in perfume oils for a wide range of applications, especially in perfume oils for soaps, shower gels and shampoos. 

C10H10O3, Mr 178.19, is a white powder with a fresh marine odor, mp 35-41 °C. It is used to create fresh aquatic marine notes in perfume oils for many applications, e.g., for fine fragrances, soaps, and shower gels. 

This cosmopolitan family, represented especially well in South Africa, the eastern Mediterranean, and Central and South America, is known for its garden flowers, the spice saffron, and the genus Iris for its perfume oils. 

The violets are cosmopolitan with Viola temperate. They include a few sources of medicinals and perfume oils, but most are valued as garden plants. 

Perfumes, colognes and toilet waters are solutions of perfume oils in specially denatured alcohols, (ethyl alcohol with various denaturants which make it unsuitable for human consumption). In addition, ethanol is used as a solvent for flavors, as an extraction solvent for many natural products and as a reagent for the production of many ethyl esters. Summing up all these uses, the quantity of ethanol used in the fragrance and flavor industry tops all other alcohols by far. 

Oxidation is also the main cause of perfume instability in poor-quality toilet soaps here it is caused by the fatty acid peroxides formed at the stage of incipient rancidity. Perfumes may to some extent be protected against oxidation by the incorporation of 1% to 2% of an antioxidant such as BHT (butylated hydroxy toluene) into the perfume oil. 

Discoloration is also sometimes observed in alcoholic perfumes in clear glass bottles. Here the problem involves the action of light and air upon sensitive perfume materials. It can sometimes be alleviated by the addition of a sunscreen to the finished perfume. Sunscreens should not be incorporated directly in perfume oils since they may contribute to instability. 

Although the perfume oil is usually the first suspect whenever odor or color changes occur in a finished product, it is not always the culprit. Odor and color changes in the product base itself may occur due to oxidation, hydrolytic breakdown, complex formation, bacterial decomposition, or other causes. Sometimes the causes for instability are hard to track down, as in a case in the experience of one of the authors, where an off-odor in a cream was due to microbial breakdown that was made possible by absorption and inactivation of the preservative by the plastic container. It is always advisable to conduct a stability test of the unperfumed product along with the test of the perfumed product. 

Interactions between the perfume oil and the plastic are possible. Fortunately the instances of such interactions are rare, but when they occur, most likely in water-based, oil-free products with high perfume levels such as gel or liquid air fresheners or rim blocks, they can be quite annoying, since they may lead to the leaking of containers, the clogging of valves, and so on. Esters are particularly likely to interact with the more commonly used plastics. The problem may sometimes be remedied by replacing any esters used as solvents in the perfume compound by dipropylene glycol and by formulating the perfume to provide the desired intensity at the lowest possible perfume level. Discoloration of white plastic is usually caused by the same perfume materials that cause discoloration in white soaps (see Chapter 16). 

To protect the safety of the operators who handle perfume oils in bulk, most countries have issued directives for labeling such oils. These usually include information regarding flammability and toxicity hazards. They do not normally affect perfumers in their task of creating perfumes. 

Projects that depend upon the manufacture of perfume oils in countries with import restrictions. 

On account of its exceptionally penetrating nature, benzylidene acetone should be used in perfumery with great caution, and only as a 10% solution in alcohol. Its stability to alkali makes it of special value for soap-perfume oils. In its concentrated state benzylidene acetone violently attacks the skin. 

Dibutyl phthalate has multiple uses in a variety of materials. Primary uses for dibutyl phthalate are to soften and increase plastic flexibility, for example, in shower curtains, raincoats, food wraps, and car interiors to name a few. It has been used in insect repellents and as a solvent for perfume oil and resins. Dibutyl phthalate can be used as a plasticizer in nitrocellulose lacquers, elastomers, explosives, nail polish, and solid rocket propellants. Other uses include perfume fixative, textile lubricating agent, safety glass additive, printing inks, and adhesives.

As outlined when discussing absorption bases, the drug may also be dissolved in water to form a solution to be levigated into an ointment base or cream. Such addition softens creams even to the point of converting them to thick lotions. The chosen vehicle, of course, must have an inherent capacity to emulsify or otherwise take up the solution. Aromatic materials such as essential oils, perfume oils, camphor, and menthol, which volatilize if added when the base is hot, are incorporated into these semisolids while they are stiU being mixed but near the temperature where a particular system starts to congeal. Volatile materials are often introduced into the formulation as hydroalcoholic solutions.
