一般描述

鼠李糖脂生物表面活性剂是一类含有L-鼠李糖和ß-羟基脂肪酸的糖脂，具有两亲性（亲水性和疏水性）。该鼠李糖脂产物是从铜绿假单胞菌中纯化得到的，含有鼠李糖脂和不同尾长脂肪酸的混合物。它们具有高度可生物降解性、无毒且可再生。其功能包括生物活性、表面活性剂和乳化剂。鼠李糖脂具有良好的去污性、起泡性、润湿性，能够形成稳定的微乳液并可在高碱度下具有溶解性。它们较为温和，具有护肤属性。鼠李糖脂的表面活性剂和乳液性质包括可将水的表面张力降低到25-40 mN/m，具有5-380 mg/L的CMC，以及将油和水的界面张力降低到<1达因/cm。鼠李糖脂生物表面活性剂优于合成表面活性剂的主要原因包括：其CMC比传统化学表面活性剂低10-100倍（意味着需要显著更少的材料便能减少表面张力/界面张力）；易于生物降解，并具有很低的毒性（具有较高的EC50值）；不受温度、pH值和盐度的影响；可持续生产。

我们致力于为您带来更加绿色的替代产品，这些产品遵守一项或多项绿色化学12项原则。该产品的碳氢化合物降解已被增强。如需更多信息，请参阅文献生物表面活性剂的环境应用：近期进展，以及位于此处的其他文章：AGAE技术

Interspecies bacterial competition may occur via cell-associated or secreted determinants and is key to successful niche colonization. We previously evolved Pseudomonas aeruginosa in the presence of Staphylococcus aureus and identified mutations in the Wsp surface-sensing signalling system. Surprisingly, a ΔwspF

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
