Abstract: Laminates having a foamed polyethylene layer reduces material costs but yet can be used to make user-acceptable bags and other containers to hold consumable products (such as a dry laundry detergent) that withstand the rigors of manufacturing and transporting.
Abstract: The present invention discloses a microbial culture medium and a cultural method. The culture medium comprises a combination of strong acid-weak alkali salts and strong alkali-weak acid salts so that pH value thereof can be regulated and controlled in a stable and suitable range by itself, thus decreasing or eliminating an operable regulation on pH value via an external device in fermentation process and a risk of contaminations resulted from it in fermentation process as well, accordingly greatly improving the controllability and stability of the fermentation process. Meanwhile the ammonium salts acting as strong acid-weak alkali salts can be used as a nitrogen source to replace yeast cream to realize a decreased amount of nitrogen resource of high price, therefor sharply reducing the cost of the culture medium.

Abstract: Oil in water emulsion compositions, and methods for preparing such emulsions, where the oil phase component of the emulsion contains at least 50 weight percent of a low molecular weight siloxane are disclosed. The oil in water emulsions are stabilized by a combination of a silicone polyether and anionic surfactant. The oil in water emulsions, and subsequently diluted emulsions therefrom, are stable with time and are useful in a variety of personal, medical, and household care formulations.
