Petroleum jelly white is the malthenes purified from lubrication oil, the mixture of residue oil and cerate.
Petroleum jelly white is an important lubricant for medicines, cosmetics, fine chemical raw materials and precision instruments.
In China, major vaseline products include ordinary vaseline, industrial vaseline and medical vaseline.
Petroleum jelly white, white petrolatum, soft paraffin, or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties.
Petroleum jelly white has been the leading brand of petroleum jelly since 1870.
Petroleum jelly white became a medicine-chest staple, consumers began to use it for cosmetic purposes and for many ailments including toenail fungus, genital rashes (non-STI), nosebleeds, diaper rash, and common colds.
Petroleum jelly whites folkloric medicinal value as a "cure-all" has since been limited by a better scientific understanding of appropriate and inappropriate uses.
Petroleum jelly white is recognized by the U.S. Food and Drug Administration (FDA) as an approved over-the-counter (OTC) skin protectant and remains widely used in cosmetic skin care, where it is often loosely referred to as mineral oil.
Petroleum jelly white (often called white petrolatum, soft paraffin, or simply Vaseline) is a highly purified mixture of semi-solid hydrocarbons derived from petroleum.
Petroleum jelly white is colorless to slightly white in appearance, odorless, and has a smooth, ointment-like texture.
This refined form is different from yellow petrolatum, as it undergoes more purification to remove impurities, resulting in a cleaner and more stable product that is widely accepted for cosmetic, medical, and pharmaceutical use.
Petroleum jelly white functions primarily as an occlusive moisturizer, meaning it creates a protective barrier on the surface of the skin that locks in moisture and prevents water loss.
Because of this property, it is used extensively in skin protectants, healing ointments, baby care products, lip balms, and cosmetics.
In medicine, white petroleum jelly is commonly recommended to protect minor cuts, scrapes, and burns, as well as to prevent chafing and irritation.
Petroleum jelly white is mainly used in topical pharmaceutical formulations as an emollient-ointment base, it is poorly absorbed by the skin.
Petroleum jelly white is also used in creams and transdermal formulations and as an ingredient in lubricant formulations for medicated confectionery together with mineral oil.
Therapeutically, sterile gauze dressings containing Petroleum jelly white may be used for nonadherent wound dressings or as a packing material.
Petroleum jelly white is additionally widely used in cosmetics and in some food applications.
Petroleum jelly white described the oil exportation of Baku oil by hundreds of camels and ships for burning and as an ointment for treating mange.[3]
Native Americans discovered the use of petroleum jelly for protecting and healing the skin.[4] Sophisticated oil pits had been built as early as 1415–1450 in Western Pennsylvania.[5] In 1859, workers operating the United States's first oil rigs noticed a paraffin-like material forming on rigs in the course of investigating malfunctions. Believing the substance hastened healing, the workers used the jelly on cuts and burns.[6][7]
Robert Chesebrough, a young chemist whose previous work of distilling fuel from the oil of sperm whales had been rendered obsolete by petroleum, went to Titusville, Pennsylvania, to see what new materials had commercial potential.
Petroleum jelly white took the unrefined green-to-gold-colored "rod wax", as the drillers called it, back to his laboratory to refine it and explore potential uses.
He discovered that by distilling the lighter, thinner oil products from the rod wax, he could create a light-colored gel.
Petroleum jelly white patented the process of making petroleum jelly by U.S. patent 127,568 in 1872.
The process involved vacuum distillation of the crude material followed by filtration of the still residue through bone char.
Petroleum jelly white traveled around New York demonstrating the product to encourage sales by burning his skin with acid or an open flame, then spreading the ointment on his injuries and showing his past injuries healed, he said, by his miracle product.
He opened his first factory in 1870 in Brooklyn using the name Vaseline.
Petroleum jelly white is a mixture of hydrocarbons, with a melting point that depends on the exact proportions.
The melting point is typically between 40 and 70 °C (105 and 160 °F).
Petroleum jelly white is flammable only when heated to liquid; then the fumes will light, not the liquid itself, so a wick material is needed to ignite petroleum jelly.
Petroleum jelly white is colorless (or of a pale yellow color when not highly distilled), translucent, and devoid of taste and smell when pure.
Petroleum jelly white does not oxidize on exposure to the air and is not readily acted on by chemical reagents.
Petroleum jelly white is insoluble in water.
Petroleum jelly white is soluble in dichloromethane, chloroform, benzene, diethyl ether, carbon disulfide and turpentine.
Petroleum jelly white is slightly soluble in alcohol.
Petroleum jelly white acts as a plasticizer on polypropylene (PP), but is compatible with a wide range of materials and chemicals.
It is a semi-solid, in that it holds its shape indefinitely like a solid, but it can be forced to take the shape of its container without breaking apart, like a liquid, though it does not flow on its own.
At room temperature, it has 20.9% solid fat content.
Petroleum jelly whites microstructure is made up of partially crystalline stacks of lamellar sheets which immobilize the liquid portion.
In general, only 7–13% of it is made up of high molecular weight paraffins, 30–45% of smaller paraffins, and 48–60% of small paraffins.
Depending on the specific application of petroleum jelly, it may be USP, B.P., or Ph. Eur. grade.
This pertains to the processing and handling of the Petroleum jelly white so it is suitable for medicinal and personal-care applications.
Petroleum jelly white is a mixture of hydrocarbons produced during the oil refining process, filtered and distilled.
Suitable for numerous application including waterproofing and barrier protection.
Petroleum jelly white is used in creams, lotions, lip balms and salves.

Petroleum jelly white ensure that white petroleum jelly is highly refined, free of harmful contaminants, and safe for topical application.
Petroleum jelly whites purity and stability also make it an important base ingredient in many pharmaceutical ointments, creams, and topical formulations.
Petroleum jelly white is a purified, semi-solid mixture of saturated hydrocarbons obtained from petroleum refining.
Petroleum jelly white usually has a melting point between 38–60 °C and is highly stable against oxidation and rancidity.
Petroleum jelly whites white or translucent appearance comes from the removal of aromatic hydrocarbons and other impurities that may be present in less refined grades of petrolatum, such as yellow petrolatum.

Petroleum jelly white is manufactured from the semisolid residue that remains after the steam or vacuum distillation of petroleum.
This residue is dewaxed and/or blended with stock from other sources, along with lighter fractions, to give a product with the desired consistency.
Final purification is performed by a combination of high-pressure hydrogenation or sulfuric acid treatment followed by filtration through adsorbents.
Petroleum jelly white a suitable antioxidant may be added.

Transparent when thin-layered, slightly fluorescent.
Insoluble in water, almost insoluble in cold or hot ethanol and cold anhydrous ethanol.
Soluble in ether, hexane and most volatile or non-volatile oil, easily soluble in benzene, carbon disulfide, chloroform and turpentine.
The production of Petroleum jelly white involves multiple steps of distillation, dewaxing, and purification, often using filtration through activated carbon and clay treatments to achieve pharmaceutical or cosmetic grade quality.
Because of this extensive refining, Petroleum jelly white is considered safer for direct contact with skin and mucous membranes compared to lower-grade petrolatums used in industrial lubricants or technical applications.
Petroleum jelly white is a traditional method for the production of petrolatum (vaseline), which is still in use at home and abroad.
In the process, add sulfuric acid with more than 98% concentration measured up to about 60% of raw materials and mix it with the raw material in the reactor.
The reaction temperature is kept at 70℃.
After the reaction, the acid residue is separated and diluted with alcohol to further remove the acid residue.
The oil treated with acid in another clay refining tank is decolorized with carclazyte at about 140℃, and then filtered to obtain the final product.
The characteristics of the acid-carclazyte method: the high-quality parts can be produced, PAHs can reach the level of pharmaceutical grade and other relevant indicators can meet the quality index of the pharmacopoeia, which is the reason of traditional craft&rsquo, s long time existence.
The main disadvantage of the method is too low goal product yield (about 50%) and a large number of acid residues which is difficult to be utilized resulting in serious environmental pollution and very high production cost.
Aluminum chloride method has taken place of acid-carclazyte method to produce vaseline from 60s at home.
The process is as follows: the raw material reacts with aluminum chloride after dehydration in the reactor, reaction temperature is between 130℃ to 140℃.
After the reaction, the oil will be neutralized and precipitated with alkali liquor in the neutralization tank.
Then remove the slag and refine by carclazyte adsorption in the decolorizing tank.
Petroleum jelly white is obtained by filtering refined oil at about 120℃.
The yield of aluminum chloride method is higher than that of acid-carclazyte method, and consumption index seems lower, but the quality is slightly worse, compared with vaseline produced by medium-pressure hydrocracking and high pressure hydrogenation was there is a great gap in color, transparency, the content of polycyclic aromatic hydrocarbons and so on.
Hydrogenation method is a new process for the production of vaseline, which is usually carried out with 10, 20, or 30MPa and lower liquid hourly space velocity.
The process is to convert the useless components in the raw materials into effective components, so that the product yield can be nearly 100%.
But aluminum chloride method or acid-carclazyte method changes useless components into waste slags to dump containing effective components, which reduces the product yield.
Due to the product yield, the refining extent of luminum chloride method or acid-carclazyte method is also limited, thus limiting the further improvement of product quality.
So the hydrogenation method is better than aluminum chloride method and acid-carclazyte method both in product yield or quality.
Storage Of Petroleum jelly white:
Petroleum jelly white is an inherently stable material owing to the unreactive nature of its hydrocarbon components, most stability problems occur because of the presence of small quantities of impurities.
On exposure to light, these impurities may be oxidized to discolor the petrolatum and produce an undesirable odor.
The extent of the oxidation varies depending upon the source of the petrolatum and the degree of refinement.
Oxidation may be inhibited by the inclusion of a suitable antioxidant such as butylated hydroxyanisole, butylated hydroxytoluene, or alpha tocopherol.
Petroleum jelly white should not be heated for extended periods above the temperature necessary to achieve complete fluidity (approximately 70°C).
Petroleum jelly white may be sterilized by dry heat.
Although Petroleum jelly white may also be sterilized by gamma irradiation, this process affects the physical properties of the petrolatum such as swelling, discoloration, odor, and rheological behavior.
Petroleum jelly white should be stored in a well-closed container, protected from light, in a cool, dry place.

It forms a film on the skin’s surface, preventing moisture loss caused by evaporation, and protecting against irritation.
Its disadvantage lies in the difficulty of effectively and properly removing it from the skin.
Studies indicate that petrolatum accelerates the recovery of skin surface lipids, permeating throughout the stratum corneum layer, and allowing normal barrier recovery despite its occlusive properties.
Thus it does not form or act as an impermeable membrane.

Petroleum jelly white is mainly used in topical pharmaceutical formulations and is generally considered to be a nonirritant and nontoxic material.
Animal studies, in mice, have shown petrolatum to be nontoxic and noncarcinogenic following administration of a single subcutaneous 100 mg dose.
Similarly, no adverse effects were observed in a 2-year feeding study with rats fed a diet containing 5% of petrolatum blends.
Although Petroleum jelly white is generally nonirritant in humans following topical application, rare instances of allergic hypersensitivity reactions have been reported,as have cases of acne, in susceptible individuals following repeated use on facial skin.
However, given the widespread use of petrolatum in topical products, there are few reports of irritant reactions.
The allergic components of Petroleum jelly white appear to be polycyclic aromatic hydrocarbons present as impurities.
The quantities of these materials found in Petroleum jelly white vary depending upon the source and degree of refining.
Hypersensitivity appears to occur less with white petrolatum and it is therefore the preferred material for use in cosmetics and pharmaceuticals.
Petroleum jelly white has also been tentatively implicated in the formation of spherulosis of the upper respiratory tract following use of a petrolatum-based ointment packing after surgery,and lipoid pneumonia following excessive use in the perinasal area.
Other adverse reactions to Petroleum jelly white include granulomas (paraffinomas) following injection into soft tissue.
Also, when taken orally, Petroleum jelly white acts as a mild laxative and may inhibit the absorption of lipids and lipid-soluble nutrients.
Petroleum jelly white is widely used in direct and indirect food applications.
In the USA, the daily dietary exposure to petrolatum is estimated to be 0.404 mg/kg body-weight.
