General description
ECO Brij® L4, also known as polyethylene glycol lauryl ether, is a bio-based, nonionic surfactant manufactured from naturally occurring straight-chain lauryl alcohol. This detergent, derived from natural sources, provides various functional advantages, such as detergency, emulsification, and wetting, making it suitable for a range of applications in biochemical and biological research.
The ECO Brij series of ethoxylated fatty alcohols are non-ionic surfactants manufactured using renewable sources. ECO Brij L4 is a mixture of tetraethylene glycol alkyl ethers, primarily dodecyl (C12) ether. The alkyl ether profile of ECO Brij L4 may differ lot-to-lot due to natural variability in the lipid starting material (palm oil).
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is a biobased surfactant and is aligned with the 7th principle of Green Chemistry "Use of Renewable Feedstocks" and the 10th principle "Design for Degradation".

The minimally-invasive nature of sclerotherapy makes it one of the first treatment options for venous malformations, although treatment-related complications, such as peripheral nerve paralysis, have been reported in some clinical cases. However, no studies of the aetiology of the detrimental

New minimally invasive treatment modalities, such as ultrasound-guided foam sclerotherapy (UGFS), are becoming more popular. In a multicentre randomized controlled non-inferiority trial, the effectiveness and costs of UGFS and surgery for treatment of the incompetent great saphenous vein (GSV) were

Sclerotherapy is useful for the treatment of arteriovenous vascular malformations. However, intravascular administration of sclerotic agents into small arteriovenous niduses is often difficult. Extravascular administration of sclerotic agents causes reduction of vascular flow on Doppler echo during clinical sclerotherapy. Therefore
