A container with cream. Topical cream formulation is an emulsion semisolid dosage form that is used for skin external application. Most of the topical cream formulations contain more than 20 per cent of water and volatiles and/or less than 50 per cent of hydrocarbons, waxes, or polyethylene glycols as the vehicle for external skin application.

Alginate is used as an ingredient in various pharmaceutical preparations, such as Gaviscon, in which it combines with bicarbonate to inhibit gastroesophageal reflux. [citation needed] Sodium alginate is used as an impression-making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting. [citation needed]
Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture.
Moisturizing barrier cream acts as a lubricating film on the skin to prevent depletion of water (transepidermal water loss) in the skin's outermost layer, the stratum corneum. [5] This may have a protective effect against irritant contact dermatitis and allergic contact dermatitis , which often result from such depletion. [ 5 ]
Similarly to how water dropped into a quantity of oil forms a bubble of water in the oil, each drop of the alginated liquid tends to form into a small sphere in the calcium solution. During a reaction time of a few seconds to a few minutes, the calcium solution causes the outer layer of each alginated liquid sphere to form a thin, flexible skin.
Lotion is a low-viscosity topical preparation intended for application to the skin. By contrast, creams and gels have higher viscosity, typically due to lower water content. [1] [2] Lotions are applied to external skin with bare hands, a brush, a clean cloth, or cotton wool.
Calmurid Cream contained the active ingredients lactic acid and urea, [1] whereas Calmurid HC contained an additional ingredient, the mild corticosteroid hydrocortisone. Owing to lactic acid's keratolytic properties (to break down hard skin cells) and urea's hydrating properties, Calmurid was used primarily in the treatment of dry, scaly skin.
British researchers found evidence that using the cream to moisturize areas affected by eczema may actually aggravate the condition. [2] They suggested this was due to skin-thinning effects of a detergent sodium lauryl sulfate. The National Eczema Society recommends alternatives such as white soft paraffin wax or other types of emollient ...
