White Petroleum Jelly or Petrolatum or Soft Paraffin
Petroleum jelly or petrolatum or white petrolatum or soft paraffin or multi-hydrocarbon, is a semi-solid mixture of hydrocarbons, originally promoted as a topical ointment for its healing properties. Petroleum jelly’s benefits come from its main ingredient petroleum, which helps seal your skin with a water-protective barrier. It is recognized by the U.S. A. Food and Drug Administration as an approved over-the-counter (OTC) skin protectant and remains widely used in cosmetic skin care. Most uses of petroleum jelly exploit its lubricating and coating properties, including use on dry lips and dry skin.
Specifications of White Petrolatum USP & NF Grade:
DEFINITION
White Petrolatum is a purified mixture of semisolid hydrocarbons obtained from petroleum, and wholly or nearly decolorized. It may contain a suitable stabilizer.
Residue on Ignition:
Sample: 2 g
Analysis: Heat the Sample in an open porcelain or platinum dish over a flame.
Acceptance criteria: It volatilizes without emitting an acrid odor and yields NMT 0.05% of residue.
Procedure: Organic Acids:
Sample solution: 20.0 g of White Petrolatum in 100 mL of a 1 in 2 mixture of neutralized alcohol and water. Agitate thoroughly and heat to boiling.
Analysis: Add 1 mL of phenolphthalein and titrate rapidly with 0.1 N sodium hydroxide, with vigorous agitation to the production of a sharp pink endpoint, noting the color change in the alcohol–water layer.
Acceptance criteria: NMT 400 microL of 0.1 N sodium hydroxide is required.
Color: To pass the test.
Specific Gravity: 0.815–0.880 at 60C
Melting Range or Temperature:38C –60C
Consistency: To pass the test.
Alkalinity:
Sample: 35 g
Analysis: Introduce the Sample into a suitable beaker, add 100 mL of boiling water, cover, and place on a stirring hot-plate maintained at the boiling point of water. After 5 min, allow the phases to separate. Draw off the separated water into a casserole, wash the petrolatum further with two 50-mL portions of boiling water, and add the washings to the casserole. To the pooled washings, add 1 drop of phenolphthalein, and boil.
Acceptance criteria: The solution does not acquire a pink color.
Acidity:
Sample: Final solution of the test for Alkalinity, if the addition of phenolphthalein produced no pink color
Analysis: To the Sample, add 0.1 mL of methyl orange.
Acceptance criteria: No red or pink color is produced.
Fixed Oils, Fats, and Rosin:
Sample: 10 g
Analysis: Digest the Sample with 50 mL of 5 N sodium hydroxide at 100° for 30 min. Separate the water layer, and acidify it with 5 N sulfuric acid.
Acceptance criteria: No oily or solid matter separates.
Packaging and Storage: Preserve in well-closed containers.
Labeling: Label it to indicate the name and proportion of any added stabilizer.
