Montanov L

This non-ionic emulsifying blend is made from plant-derived fatty alcohols and sugar glucosides. It combines the water and oil phases into a light emulsion and forms ordered lamellar structures similar to the skin's lipid layers. It is a functional ingredient used in creams, fluids, cleansing milks and sunscreens.

Montanov L stabilises the emulsion, improves spreadability and forms a soft, non-greasy film. The lamellar structure may help release water and lipids more evenly onto the skin's surface, helping the skin feel hydrated. The emulsifier itself does not treat dryness or inflammation, but a well-structured cream has a significant influence on comfort, barrier repair and how evenly active ingredients are distributed over the skin.

It is suitable for products for normal, dry, sensitive and combination skin. Its lightweight feel also makes it suitable for daytime fluids and creams for warm or humid climates. For oily skin, the result depends on the amount of the oil phase. For very sensitive skin, its non-ionic nature and the option to formulate without harsh surfactants are advantages.

The manufacturer assessed the moisturising properties of emulsions containing Montanov emulsifiers on different skin phototypes and in different climatic conditions. Tests showed increased hydration and confirmed that Montanov L enables lightweight formulations suitable even for hot and humid environments (Seppic Clinical Evaluation). These data relate to the emulsion system, not to an independent therapeutic effect.

The usual concentration is approximately 1 to 5 per cent, depending on the amount of the oil phase and the desired viscosity. It requires heating and proper homogenisation. Stability is affected by the ratio of the phases, electrolytes, polymers and the cooling profile, so stress testing and long-term testing are necessary.

For the user, its benefits are most apparent in how the product spreads, absorbs and stays on the skin. A good texture is not merely an aesthetic quality, as it supports even application of active ingredients and regular use. When assessing a finished product, it is important to check stability, pilling, stickiness and how it behaves after applying SPF or make-up. Suitable packaging and a dispensing system are also important.
