One of the most characteristic features of lanolin is its ability to absorb significant amounts of water.

Anhydrous lanolin can absorb water during rubbing in an amount exceeding its own weight, while maintaining its characteristic consistency. This feature has been utilized for decades in both pharmacy and cosmetology.

In practice, this means that lanolin not only limits moisture loss but also helps retain it within the stratum corneum.

Thanks to this property, preparations containing high-quality lanolin ensure a long-lasting feeling of comfort and improvement in skin elasticity.

A natural emulsifier with exceptional capabilities

Lanolin belongs to a relatively small group of natural raw materials that simultaneously exhibit emollient and emulsifying properties.

It can stabilize W/O (water-in-oil) emulsions, which is why it has been a valued ingredient in ointments, protective creams, and dermatological preparations for many years.

The ability to bind both lipophilic and hydrophilic components allows lanolin to facilitate the uniform distribution of many active substances in the finished preparation.

This is one of the reasons why, for over a century, it has remained an important ingredient in pharmaceutical and cosmetic formulas worldwide.

Why the quality of lanolin is of decisive importance?

All the described properties are characteristic of high-quality lanolin. However, the effectiveness and safety of using this raw material largely depend on its degree of purification.

Modern cosmetology no longer uses lanolin in its raw form. It requires the use of materials subjected to advanced refining processes, quality control, and assessment of compliance with pharmacopoeial requirements.

In the next section, we will present the history of controversies related to lanolin allergies, explain the phenomenon known as the “lanolin paradox,” and show why modern, highly purified lanolins differ significantly from the raw materials used several decades ago.
