Composition and Description

PEG-30 LANOLIN is a polyoxyethylene condensate with an average chain length of 30 ethylene oxide units. It has an average molecular weight of about 1.990 Da. The complex chemical composition of PEG-30 LANOLIN includes the natural lanolin esters and free hydroxyl groups, and the ether polymer chain. It is a soft, golden yellow wax with weak fruity odour.

Features

PEG-30 LANOLIN is a special product because it is completely soluble in water. The addition of ethylene oxide is kept to a minimum level, so as to keep the content of lanolin as a high as possible. Although it is completely water-soluble, concentrated solutions might show slight opalescence at room temperature. This insolubility is reversible upon cooling.

Applications

PEG-30 LANOLIN is a non-ionic detergent with manifold applications for emulsifying, solubilising, moisturising and cleaning without negative effects on the skin. It is used for hair setting and as plasticiser in shampoos, cleansing lotions, hand creams, detergent formulations and creams. It is also used for superfatting of soaps. The addition of cetyl alcohol or cetostearyl alcohol can increase both foam and stability of emulsion of products prepared with PEG-30 LANOLIN.

Dermatology

PEG-30 LANOLIN can be considered as an intermediate product between the pharmaceutical lanolin and PEG-75 lanolin. Both products have well-established use in cosmetic and pharmaceutical applications without any negative incidents on skin. PEG-30 LANOLIN has been used for more than 20 years and no harmful skin reactions during manufacturing and use have been observed.

Processing

When used in solutions, PEG-30 LANOLIN should first be melted, followed by addition of 3 times the amount of hot water under constant stirring. The resulting concentrate is then diluted with either hot or cold water. In order to prepare emulsions, PEG-30 LANOLIN is normally melted together with the oil phase, but it can also be dissolved in the aqueous phase. It should be stored cool in closed containers. Prolonged heating above 80 °C should be avoided.

Solubility at room temperature

Water: soluble; ethanol, anhydrous: not soluble; ethanol 80%: partly soluble; ethanol 40%: soluble; mineral oil: slightly soluble
