Bis-Behenyl …

Bis-behenyl/isostearyl/phytosteryl dimer dilinoleyl dimer dilinoleate is a plant-derived ester synthesised from phytosterols and fatty acids. It functions as an emollient and conditioning agent, designed to replicate the beneficial properties of lanolin without using animal-derived ingredients.This ingredient works primarily as a skin and hair conditioner, helping to soften and smooth the skin surface whilst also controlling product viscosity in formulations. It appears in roughly 0.7% of skincare products, typically in moisturisers, cleansing formulations, and conditioning treatments.

As an emollient, this ingredient works by forming a protective layer on the skin's surface. It fills microscopic gaps between skin cells, which can help reduce transepidermal water loss and create a smoother appearance.The ingredient has a high refractive index, which contributes to improved gloss and luminosity in formulations. Its molecular structure allows it to absorb and hold water effectively, supporting the skin's moisture levels over time.

This ingredient is typically used in leave-on skincare products such as moisturisers and serums. Apply to clean skin, allowing the product to absorb fully. It can be layered with other products and is suitable for daily use as part of a regular skincare routine.

Generally well-tolerated in skincare formulations. Those with sensitivities to plant-derived ingredients should patch test first, though adverse reactions are uncommon.
