What are the classes of ointment base?
There are three major types of ointment bases: oleaginous (greasy) bases, which are water repellent; water-absorbing bases, which are greasy but allow absorption of water, and water-miscible bases (vanishing creams or water-soluble bases).
What is the difference between oleaginous base and absorption base?
An absorption base is an oleaginous base that contains a w/o emulsifying agent. When water is taken up into the base, it will form a w/o emulsion. Absorption bases typically can incorporate about 50% of their volume in water. Incorporating insoluble drugs into these bases can be done mechanically or by fusion.
What is the base of ointment?
Typical ointment bases comprise petrolatum and mineral oil, or petrolatum and waxy/fatty alcohol combinations, the ratio and grades of these components being selected to give the desired finished product viscosity/spreadability.
What type of base is white petrolatum?
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), originally promoted as a topical ointment for its healing properties.
Which is the example of ointment base?
| Base Type | Description | Examplesa |
|---|---|---|
| Oil in water emulsion | Water insoluble Water washable Contains water Nonocclusive Nongreasy | Hydrophylic ointment Dermabase Velvachol Unibase |
| Water Soluble | Water soluble Water washable Will absorb water Anhydrous or hydrous Nonocclusive Nongreasy | Polyethylene glycol (PEG) ointment |
How do I choose an ointment base?
Many factors determine the choice of an ointment base. These include the action desired, the nature of the medication to be incorporated and its bioavailability and stability, and the desired shelf life of the finished product (1).
Which is the hydrocarbon base?
Hydrocarbon bases (or oleaginous): Ointment bases of this type contain and absorb no water. They are prepared from vegetable fixed oils or animal fats, and may contain or include lard, olive oil, cottonseed oil, and other oils. All of these oils contain glycerides, and are subject to rancidification by oxidation.
What are the two types of absorption bases?
Absorption bases are of two types: 1. Anhydrous bases that permit the incorporation of aqueous solutions, resulting in the formation of w/o emulsions. These absorption bases are anhydrous vehicles composed of a hydrocarbon base and an addi-tive.
Are ointments petroleum based?
Aquaphor and Vaseline are two brand names for petroleum jelly-based products. Both brands offer a myriad of products, from Aquaphor’s baby creams and ointments to Vaseline’s body lotions. These two products have similar uses and can help lock-in moisture for dry skin, but they’re not identical.
Which is a hydrocarbon base?
I. Hydrocarbon bases (or oleaginous): Ointment bases of this type contain and absorb no water. They are prepared from vegetable fixed oils or animal fats, and may contain or include lard, olive oil, cottonseed oil, and other oils. All of these oils contain glycerides, and are subject to rancidification by oxidation.
Who is the company that makes Eucerin products?

Eucerin are sometimes contained in products that also treat acne, chapped lips, diaper rash, cold sores, or other minor skin irritation. There are many brands and forms…
When did the first Eucerin acid ointment come out?
This all changed in 1950 when Eucerin pH5, the “acid ointment,” was launched. Although it, too, was exclusively distributed via pharmacies, it was a “finished” product and the first product to highlight the significance of stabilizing the skin’s pH value to keep its protective acid mantle intact – a central aspect of medical skin care even today.
Are there any side effects to taking Eucerin?
Ask a doctor or pharmacist if it is safe for you to use Eucerin if you have: deep wounds or open sores; swelling, warmth, redness, oozing, or bleeding; large areas of skin irritation; any type of allergy; or. if you are pregnant or breast-feeding.
