Composition and Description

BASE SE is a pale yellow, pearl-like shiny, oily O/W ointment base comprising of a well-balanced combination of ethoxylated lanolin derivatives with cetostearyl alcohol and paraffin oil. BASE SE is extremely hydrophilic and after addition of water, a stable, non-ionic O/W emulsion is obtained. Each batch is strictly controlled to ensure, among other things, a constant viscosity of the emulsions. BASE SE has a very slight characteristic odour.

Features

The product BASE SE is a pioneer of a new generation self-emulsifying bases for cosmetics and pharmaceuticals. It is not only an emulsifying wax, but it also contains all the essential ingredients for a multi-purpose cream: emulsifiers, plasticisers and lubricants with light cleaning properties. Furthermore, the consistency of emulsions prepared with BASE SE can be easily adjusted between a solid ointment to a thin lotion simply by varying the water content.

Applications

BASE SE is a multi-purpose cream base for a wide range of cosmetic products, including hair and skin creams, etc. It is compatible with most cosmetic ingredients, even with oxidising agents that are used, for example, in formulations of permanent hair waves products. In compact powder, BASE SE is a hydrophobic binder that facilitates the use of pads on wetted skin. It can be used as a unique, liquid, water-free skin cleanser. In both hospitals and pharmacies, BASE SE is used an excellent carrier for therapeutically active substances.

Dermatology

BASE SE contains only ingredients that are considered to be dermatologically safe. For more than 20 years of manufacturing and application, no irritating effects on skin were reported. Tests of acute oral toxicity reflect an extremely low toxicity.

Processing

To produce O/W emulsions, hot water is added to BASE SE under stirring condition until it is melted and a dispersion is obtained. Subsequently, the mixture is cooled below 40 °C. Homogenisation is not always necessary, but recommended when white-colored liquid emulsion is desired. When processing large amounts, it is first recommended to melt BASE SE. Lipophilic additives should be melted together with BASE SE before the addition of water. BASE SE should be kept cool. When there is excess melted material that is not completely utilised, the content should be thoroughly mixed before it is used again. BASE SE has a shelf life under normal storage conditions for at least 2 years.

Solubility at room temperature

Water: partially soluble; acetone: partially soluble; ethanol, anhydrous: partially soluble; isopropanol anhydrous: partially soluble; isopropyl myristate: partially soluble
