阅读说明：本技术 用于防止生物膜的凝胶形式的卫生剂 (Gel-form hygiene agent for preventing biofilms ) 是由 T·许米泽卡 D·波特克 于 2020-04-08 设计创作，主要内容包括：本发明涉及一个系统,其具有马桶篮筐,该马桶篮筐具有至少一个腔室,其中：以凝胶形式的自粘卫生剂存在于马桶篮筐的腔室中,并粘附于腔室套筒；所述腔室套筒在至少一侧完全封闭；并且所述卫生剂粘附于腔室套筒的完全封闭的一侧；所述卫生剂具有至少一种非离子粘附促进剂；所述非离子粘附促进剂具有至少一个疏水性官能团并且还包含亲水性基团,并且其中所述卫生剂是酸性的。(The present invention relates to a system having a toilet basket having at least one chamber, wherein: a self-adhesive sanitary agent in gel form is present in the chamber of the toilet basket and adheres to the chamber sleeve; the chamber sleeve is completely closed on at least one side; and the sanitary agent adheres to the fully closed side of the chamber sleeve; the sanitary agent has at least one non-ionic adhesion promoter; the non-ionic adhesion promoter has at least one hydrophobic functional group and further comprises a hydrophilic group, and wherein the hygienic agent is acidic.)

1. A system of

A toilet basket having at least one compartment, wherein a self-adhesive sanitary agent in gel form is present in the compartment of the toilet basket and adhered to the compartment sleeve, and wherein

The chamber sleeve is fully closed on at least one side and the sanitary agent is adhered to the fully closed side of the chamber sleeve, and wherein the sanitary agent has at least one non-ionic adhesion promoter, and wherein the non-ionic adhesion promoter has at least one hydrophobic functional group, and further comprises a hydrophilic group, wherein the sanitary agent is acidic.

2. The system of claim 1, wherein the sanitary agent has a pH of 2 to 6, preferably 3 to 5, measured in a 10% aqueous solution of the sanitary agent.

3. System according to one of the two preceding claims, in which the sanitary agent also comprises an anionic surfactant.

4. System according to the preceding claim, wherein the anionic surfactant is an ether sulphate, preferably fatty acid ethyl ether sulphate, and particularly preferably lauryl ether sulphate.

5. System according to one of the two preceding claims, in which the anionic surfactant is present in an amount of from 1% to 20% by weight, preferably from 2% to 10% by weight, based on the total weight of the sanitary agent.

6. The system according to one of the preceding claims, wherein the non-ionic adhesion promoter is a fatty alcohol alkoxylate, preferably having a degree of alkoxylation of 20 to 50EO, preferably 20 to 45 EO.

7. The system according to one of the preceding claims, wherein the sanitary agent comprises an additional non-ionic surfactant.

8. The system according to the preceding claim, wherein the further nonionic surfactant is a fatty alcohol alkoxylate, preferably having a degree of alkoxylation of 5 to 15 EO.

9. The system of the preceding claim, wherein the fatty alcohol alkoxylate has a C9 to C12 alkyl functionality, and wherein the alkyl group is preferably a non-branched alkyl functionality.

10. Preparation of the system according to the preceding claim, comprising the following steps:

making the gel flowable by heating;

introducing the sanitary agent into a basket; and

cooling the composition, wherein the hygienic agent solidifies.

Example (b):

sanitizers E1 and E2 are provided. Comparative sanitisers C1, C2 and C3 were provided.

The amounts are given in weight percent based on the total composition:

for the described embodiments, the gel composition is inserted into the toilet basket and adhered to the rim of the toilet bowl.

Biofilm can be rapidly formed in the toilet bowl. For hygienic reasons, it is desirable to prevent biofilm formation or to remove existing biofilms. It has been observed that a neutral gel composition is only insufficiently suitable for preventing biofilm formation. However, the acidic composition prevents biofilm formation. If an anionic surfactant is also used, good foaming behavior and prevention of biofilm formation can be achieved at the same time.
