White Oils description

Preparation,—The processes already described for the production of potassium are applicable also, with slight modifications, for the preparation of sodium. The apparatus required is also of exactly the same description as in the case of potassium. The substances employed are either hydrated soda and iron, or carbonate of soda and charcoal. These are placed in a malleable iron, bottle—those in which mercury Is imported answer admirably—and heated to whiteness in a powerful wind furnace. The gas, which after some time makes its appearance, is conducted into a receiver of iron or copper containing mineral naphtha or rook oil, and which receiver is kept cold by surrounding it with cold water, which is frequently changed. It should, of course, be provided with a vent for the escape of the incondensable gases evolved during the decomposition. The operation is much more productive than in the case of potassium, owing to the fortunate circumstance that sodium does not combine with carbouio oxide.

It has been ascertained that three pounds of olive-oil will yield five pounds of marbled Marseilles soap, whereas the same amount of oil will only produce four pounds four ounces of white soap, which proves that the former retains more water in its composition than the latter. French Marbled Soap.—Dussauce, in his admirable Treatise on the Manufacture of Soap, " gives an elaborate description of the manufacture of marbled soaps, as con-duoted in France, from which we give the following extracts —... 

The lipophilic phase comprises usually about 70-75 % of the total amount of the cream base. The lipophilic phase may consist of fatty oils (usually arachis oil), waxes such as decyl oleate, wool fat and white wax or hydrocarbons such as liquid paraffins or white soft paraffin (see Sect. 23.3.5 for descriptions). They determine consistency and spreadability. A w/o surfactant is added (see Sect. 12.5.4). The emulsifying properties of w/o surfactants are weaker than those of o/w surfactants. Therefore they are often used in a higher quantity. The physical stability of w/o creams is limited. Eor instance the addition of phenols, acids and alcoholic fluids may lead to phase separation. Most hydrophobic creams only include less than 5 % alcohols. 

Description Water-based, odor-free sealer resistant to salt spray, weathering, and chemicals. Makes surfaces impermeable to water vapor, gases, and other causes of surface deterioration. One coat for smooth surfaces, two coats for porous ones, so could be used as a primer on grease-, oil-, and mold-free surfaces before another encapsulant, or as a final encapsulant. Goes on white, dries clear. Aromatic solvents can remove it. No mixing required not for use on ferrous metals. One-year shelf life. 

The plant is cultivated in Indonesia, the West Indies and Sri Lanka for the production of these spices, a part of which is steam-distilled to obtain both oils, which are close in appearance and odor. N. is a pale yellow or almost water-white, mobile liquid with a typical, spicy, warm, aromatic note. Topnotes (- odor description) are light and fresh, while the body notes (->odor description) are rich, warm-spicy with woody undertones. N. finds extensive use in flavorings for meat sauces, tomato ketchups, canned soups and spice blends. In perfumery, the oil is used in fantasy floral bouquets or oriental (- odor description) perfumes, where a touch of a fresh-spicy note is required, and as a refreshing aromatic-spicy topnote in fragrances for men s perfumes, after-shaves and toiletries. 

The resulting oil is water-white or almost colorless and has a cool, fresh, typically minty topnote (- odor decription), followed by a sweet-balsamic drydown (- odor description) note. Main constituents are - menthol, menthyl esters and traces of the bitter-tasting ketone menthone. Today s main producing countries are the USA, Brazil, China, Spain, France, Italy and Japan. 

The typical constituents are cinnamic alcohol and esters of cinnamic acid, such as methyl and ethyl cinnamate. Styrax oil, steam-distilled from styrax balsam, is a pale yellow to almost water-white viscous liquid with a similar odor profile to s., except for greater diffusion and a more floral-spicy note. Both products are used in floral (jasmine, hyacinth, lilac) notes and in floral-oriental ( odor description) fragrances as booster and as a pleasant addition to the drydown (->odor description) notes.
