Description

Detergent formulations based on 2-be, nyl-4-alcoholphenol, whether or not with detergent effect, which are formulated in strongly alkaline solutions or in moderately alkaline emulsions, soaps and powders, are well known. It is also known that disinfectants prepared in solutions in an alkaline medium of sodium hydroxide are still slowly effective. This is due to the fact that even in dilute solutions, the biocidal phenol stems up to pio neutralize sodium phenolate and excess sodium hydroxide, i.e. with a time delay of about 15 to 20 minutes. In recent years, neutral liquid disinfectants have been developed. with a detergent effect based on 2-benzyl-4-chlorophenol, with a powerful and immediate effect The properties of this preparation are favorably influenced by the synergistic effect of the combination of three substances - 2-benzyl-4-chloro-rheinoil, sodium alphaolephthasulfonate and alcohol The relatively high alcohol content has a favorable effect (the cloud point of the formulation and its reduction or substitution, eg shorter-chain alpha-olefins) does not provide the desired effect. flammability (Flash point around 30 ° C), which considerably limits mo COMPANY their 'use.

It has now been found that these disadvantages do not have liquid detergent disinfectants according to the invention, which consist of 1 wt. 0.060 to 5.6 wt. alíaoleifinsulřonanů parts of sodium _C8 to C22, 0.33 lalž 3,3,5 IHM. % of sodium salts of alkyl ester sulphates of unsaturated fatty acids of C ₃ to C ₂₁ , 1.0 to 1.3 wt. Part .alifatických alcohols of C ₂ AIZ iC _4, 0.02 AIZ 1.02 wt. % of sodium sulfite and water. The liquid disinfectants according to the invention preferably contain from 0.18 to 1.2 wt. Part trletanolamtoOTých with acid-olí alfaoleíiinsulifonové of _Cg to _C18. "

A new strong synergistic system has been found in combination of 2-benzyl-4-chlorophenol with sodium alpha-olefinsulfomams and sodium salts of alkyl esters of fatty acids with at least one double bond, in the presence of a small amount of alcohol. This system is characterized by the same only those of the fungicides and fumgiciidins of the broad spectrum of microorganisms as the best prior art products, yet has a very low cloud point (below, 10 ° C) and is practically non-flammable (flash point around 80 ° C, point The new disinfectants of the present invention further eliminate the need to replenish them with baths and protective dermatological ingredients to suppress skin irritation with 2-henyl-4-chlorophenol, as they are Very good dermatological tolerability in humans and animals The inventive disinfectants of the invention have a very low toxicity (LD ₅₀ = 2000 mg / kg)> and a high biodegradability (96%). permits the long-term effect of the water-soluble film that is formed on the treatment in areas with higher relative volatility than 60%.

New Detection (The composition can be effectively applied, especially in sanitary equipment disinfection, at temperatures from -10 ° C to 60 ° C. Its cooling under foot freeze does not form separate phases, but produces a homogeneous slurry. This can be easily converted into liquid form by raising the temperature by increasing the temperature, which is of great importance for the production technology of the glazed passages.
