Definitions
- the invention relates to a process for reducing the content of free formaldehyde and formic acid in nonionic and anionic surfactants by adding selected amine compounds.
- Nonionic and anionic surfactants are important raw materials for the production of personal cleansing or body care products and cosmetic preparations, such as foam baths, hair shampoos, body lotions or creams.
- Examples include ethoxylated partial glycerides, fatty alcohol polyethylene glycol ethers and fatty alcohol ether sulfates.
- nonionic and anionic surfactants which contain ethylene oxide units in the form of polyethylene glycol ether chains, are not unlimitedly stable against oxidative degradation. With longer storage especially under the influence of Light and oxygen can therefore partially degrade the polyethylene glycol ether chain with the formation of formaldehyde or formic acid. Although both substances represent approved preservatives for cosmetics and the legal maximum values are usually far below, it is in the efforts of the raw material manufacturers to make surfactants as pure as possible, ie with the lowest possible level of impurities or degradation products available put. In this sense, there is a sustained interest in minimizing the content of undesired free formaldehyde and formic acid in anionic and nonionic surfactants.
- the object of the invention was therefore to provide a process for reducing the content of free formaldehyde and formic acid in nonionic and anionic surfactants which is free from the disadvantages described.
- the invention relates to a process for reducing the content of free formaldehyde and formic acid in non-ionic and anionic surfactants, in which the products are selected by adding an amine compound from the group consisting of
- nonionic and anionic surfactants are stabilized which contain 1 to 100, preferably 2 to 30 and in particular 2 to 10 ethylene oxide units in the form of at least one polyethylene glycol chain.
- Nonionic surfactants are to be understood as addition products of ethylene oxide with compounds having active hydrogen atoms or fatty acid esters.
- Typical examples are fatty alcohol polyglycol ethers, alkyl phenol polyglycol ethers, fatty acid polyglycol esters, fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, alkyl glucoside polyglycol ethers, mixed ethers, ethylene oxide-propylene oxide copolymers and polysorbates, and ethoxylation products of fatty acid esters, such as tri- or partial esters, for example tri- or partial esters.
- the method has proven to be particularly effective for stabilizing fatty alcohol polyglycol ethers and ethylene oxide adducts on partial glycerides.
- Anionic surfactants are to be understood as addition products of ethylene oxide with compounds having active hydrogen atoms or fatty acid esters which also contain at least one sulfate, sulfonate, carboxylate and / or phosphate group in the molecule.
- Typical examples are fatty alcohol polyglycol ether sulphates, terminal and internal alkyl polyglycol ether sulphonates, polysorbate sulphates,. Sulfosuccinates, ethylene oxide adducts with sulfonated fatty acid esters, alkyl polyglycol ether phosphates and alkyl polyglycol ether carboxylates. Has been particularly effective the method for the stabilization of fatty alcohol polyglycol ether sulfates proved.
- Alkanolamines with 2 to 15 carbon atoms can be used to stabilize the nonionic and anionic surfactants. Typical examples are monoethanolamine, mono-n-propanolamine, mono-i-propanolamine, monobutanolamine, monopentanolamine and tetrahydroxypropylethylenediamine. Monoalkanols and in particular monoethanolamine are preferably used.
- A-binocarboxylic acids which have 2 to 8 carbon atoms are suitable as a further stabilizer component.
- Typical examples are alanine, arginine, asparagine, cysteine, cystine, dibromtyrosine, diiodtyrosine, glutamine, glutamic acid, histidine, hydroxylysine, hydroxyproline, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonrosine, tryptinine, tryptinin and valine.
- the stabilization is preferably carried out with glycine.
- oligopeptides are also suitable for stabilization, for example oligopeptides, the degree of oligomerization of which is low enough to be completely water-soluble under the conditions of use and in the application concentration, for example oligopeptides with an average molecular weight of 500 to 5000. This is where such water-soluble products come in particular Consider how, for example, in the partial hydrolysis of proteins, e.g. B. gelatin or collagen [Angew. Cheai. jH), 187 (1978)].
- the stabilizers can be added to the surfactants in amounts of 50 to 6000, preferably 500 to 5000 ppm, based on the active substance of the surfactants to be stabilized.
- nonionic and anionic surfactants stabilized in the sense of the process according to the invention are practically free of formaldehyde and formic acid formed by oxidative degradation of the polyethylene glycol chain and are suitable for the production of detergents, dishwashing detergents and cleaning products and for products for hair and body care, in which they can be contained in amounts of 0.1 to 50% by weight, preferably 1 to 25% by weight, based on the composition.
- Aqueous, approximately 30% by weight surfactant pastes were stored in sealed, light glass bottles at a temperature of 20 ° C. and under the influence of light without or with the addition of a stabilizer for a period of 3 months; the content of formaldehyde and formic acid was determined by gas chromatography, the final value being set at 100% after 3 months' storage without the addition of a stabilizer.
