The invention relates to the use of a composition comprising a) 3,3'-methylenebis(5-methyl oxazolidine) and b) one or more additives selected from among (i) urea, urea derivatives, amino acids, guanidine and guanidine derivatives and (ii) 1,2-diols in the removal of sulphur compounds from process streams. The composition is preferably used in the removal of hydrogen sulphide from process streams.

Use of compositions having a content of 3,3'-methylenebis(5-methyloxazolidine) in the removal of sulphur compounds from process streams

Disclosed is a storage-stable condensation product prepared from 1-amino-2-propanol and formaldehyde in a molar ratio in the range from 1:2.0 to 1:3.1. The condensation product contains less than 10% by weight of water. Also, disclosed is the preparation of the condensation product and the use thereof for reducing the amount of hydrogen sulphide in liquids and gases.

Condensation product of 1-amino-2-propanol and formaldehyde and the use thereof for reducing the amount of hydrogen sulphide in liquids and gases

Liquid concentrate for the protection of compositions to be applied topically, against microbial attack

A composition which includes a) ferulic acid ethyl ester and b) one, two or more aryl alkanols. The combination of components a) and b) has an antimicrobial effect on products such as cosmetics.

Composition comprising ferulic acid ethyl ester and aryl alkanol

Disclosed is an antimicrobial composition that includes a) one or more C3 to C5 alkane dioles-1,3, b) one or more aromatic alcohols and c) one or more C8 to C14 alkanols. A preferred component a) is propane diol-1,3. Preferred components b) are phenoxyethanol and phenethyl alcohol. A preferred component c) is undecanol-1. Optionally, an antioxidant c) is present, which is preferably Vitamin E. In a preferred embodiment the composition is a concentrate and is suitable for the antimicrobial finishing of dermatological, cosmetic and pharmaceutical products.

Mixture of natural or nature-identical alcohols with improved effectiveness

Microbicidal preparations containing a) at least one 1,2-benzisothiazolin-3-one or its derivatives; b) at least one 2-mercaptopyridine N-oxide, or its salts and derivatives; c) at least one aromatic alcohol; and d) at least one alkalinizing agent, or a preparation prepared by mixing components a) to d), and having a pH of at least 11, are provided. The microbicidal preparations are clear and storage-stable, and are suitable for use as preservatives.

Method for reducing the formaldehyde emission of a composition containing a formal by adding urea, urea derivatives, amino acids, guanidine or guanidine derivatives.

Reducing formaldehyde emissions in formal-containing compositions

A process for the preparation of a 1-alkyl glycerol ether of the formula (I) in which: (a) an alkyl glycidyl ether of the formula (II) in which R is an unbranched or branched C- to C-alkyl group, where the alkyl group may be substituted with one or more hydroxy and/or C- to C-alkoxy group(s) and/or the alkyl chain may be interrupted by up to four oxygen atoms, is added to: (x) a carboxylic acid having 1-10 carbon atoms; (y) an ester of a carboxylic acid having 1-10 carbon atoms; and/or (z) an anhydride of a carboxylic acid having 1-10 carbon atoms. The low-water reaction mixture containing a catalytic amount of a strong acid is reacted at a temperature of more than 40&#xb0; C. to give an acylated alkyl glycerol ether; and (b) the acylated alkyl glycerol ether is reacted in order to obtain the alkyl glycerol ether of the formula (I).

Process for the preparation of 1-alkyl glycerol ethers
