A 2012 scientific opinion by the European Food Safety Authority stated that mineral oil aromatic hydrocarbons (MOAH) and polyaromatics were potentially carcinogenic, and may present a health risk.

If pure paraffin wax melted to the approximate flash point in a half open glass vessel which is then suddenly cooled down, then its vapors may autoignite as result of reaching boiling liquid pressure.

Simply applying it before applying other medicated creams may only dilute those medicines. When using white soft paraffin regularly to smooth and soften your skin, allow sufficient time to pass between applying the paraffin and applying your other topical medications.

Most petroleum jelly today is used as an ingredient in skin lotions and cosmetics, providing various types of skin care and protection by minimizing friction or reducing moisture loss, or by functioning as a grooming aid (e.g., pomade). It is also used for treating dry scalp and dandruff. [22] Preventing moisture loss [ edit ]

Is a purely synthetic dressing that is biocompatible and absorbable. Main constituent is polylactic acid. Loughran S, Spinou E, Clement WA, et al.

In a histology or pathology laboratory, paraffin wax is used to impregnate tissue prior to sectioning thin samples. Water is removed from the tissue through ascending strengths of alcohol (75% to absolute), and then that is cleared in an organic solvent such as xylene. The tissue is then placed in paraffin wax for several hours, then set in a mold with wax to cool and solidify. Sections are then cut on a microtome.

It can be used to finish and protect wood, much like a mineral oil finish. It is used to condition and protect smooth leather products like bicycle saddles, boots, motorcycle clothing, and used to put a shine on patent leather shoes [26] (when applied in a thin coat and then gently buffed off).

Petroleum jelly, petrolatum, 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), [1] originally promoted as a topical ointment for its healing properties. [2] Vaseline has been a well-known American brand of petroleum jelly since 1870. Petroleum jelly contains mineral oil aromatic hydrocarbons (MOAH). Many MOAH, mainly polycyclic aromatic hydrocarbons (PAH), are considered carcinogenic. The content of both MOAH and PAH in petroleum jelly products varies. The EU limits PAH content in cosmetics to 0.005%. The risks of PAH exposure through cosmetics have not been comprehensively studied, but food products with low levels (<3%) are not considered carcinogenic. [35] In conditions such as eczema, using a moisturiser regularly, even once the skin has improved, can help prevent flare-ups of this condition.When the wax is completely melted, take the boiler off the stove. Carefully pour the wax into a greased plastic container.
