Description

The proposed composition is a composition that forms a foam, resistant to electrolytes, containing components that regulate the expansion rate and stability of the obtained foams, allowing to obtain compositions for the production of foams for football referees with the required combination of properties based on non-toxic biodegradable components.

The technical field to which the invention relates

The invention relates to household chemicals and sports goods, namely to foaming compositions, in particular to agents used as a marker to obtain foam with limited stability, for example, on a playing field, on a football field or rugby field, and intended for sports arbitrators.

State of the art

There are numerous formulations of foamable compositions containing as foaming agents all kinds of natural and synthetic surfactants as individual substances or in various combinations. For most of these formulations, parameters such as foam rate, initial foaming rate, foam type and consistency, rinse off, feeling after use, etc., are regulated. At the same time, such parameters of foam as its stability and lifetime are in most cases not evaluated and are not the subject of most inventions. On the other hand, when developing foaming compositions, the requirements for the biodegradability of the components included in such compositions may not be taken into account at all. The closest area in which such foam characteristics as the multiplicity and biodegradability of components (environmental requirements) are taken into account is the area of creating cosmetic compositions and care products such as shampoos, bath foams, etc., however, for compositions of this type, the controlled rate of foam destruction is not is the subject of inventors.

Certain specialty agents are also known for creating referee foams with adjustable stability. In particular, in US patent US 20120148741, it is proposed to use compounds of the Tween 20 type (PEG-20 sorbitan monolaurate) as the main foaming agent, and urea derivatives (diazolinidyl urea), butyl carbamate and propylene glycol as agents regulating the rate of foam destruction. In the Chinese patent CN 104624118, it is proposed to use sodium alkyl sulfates and / or sulfoethoxylates as foaming agents, while the foaming ability of the compositions is controlled by the introduction of various amounts of polydimethylsiloxane, which is emulsified using an alkyl polyglucoside.

The main disadvantage of these compositions is the use of surfactants and components with poor or insufficiently high biodegradability.

The essence of the invention

The objective of the present invention was to create a foaming composition based on biodegradable surfactants with controlled stability and foam lifetime, as well as having such a combination of properties as a high expansion rate and a short foam lifetime.

The technical result achieved in the present invention is that the proposed composition contains a homogeneously distributed combination of components that provide a fast initial pricing rate and a high expansion rate of foam, and components that are adsorbed during the redistribution of concentrations on the surface of gas bubbles, which reduce the surface tension and lead to an increase in the rate of destruction of the created foam. At the same time, the composition includes components that ensure the stability of the composition over time, as well as other necessary components that give the foam the required properties, such as fragrances, dyes, etc. As foaming and emulsifying components in the proposed composition, environmentally friendly surfactants with high values of the renewable carbon index.

This task is solved by creating a stable multicomponent composition, including

1) one or more components that give the composition a high foaming ability

2) a component responsible for controlling the stability of the foam, providing the required lifetime of the formed foam

3) a component that acts as a preservative, ensuring high stability of the entire composition

4) solvent - distilled water or a mixture of distilled water with additives of non-toxic biodegradable organic polar solvents

The results of evaluating the properties of the compositions presented in Examples 1-8.

Evaluation of the expansion rate and foam stability was carried out at a temperature of 25 ° C.

To assess the expansion rate of the foam (the ratio of the volume of the foam to the volume of the liquid contained in it), the gravimetric method was used. The foam rate was found as the ratio of the mass of 100 ml of the dispersion medium (foaming composition prepared with deionized water) to the mass of 100 ml foam according to the formula (1):

- масса сухого градуированного цилиндра на 100 мл;

- масса градуированного цилиндра, заполненного водным пенообразующим раствором;

- масса градуированного цилиндра, заполненного свежсформированной пеной.Where

- mass of dry graduated cylinder per 100 ml;

- the mass of the graduated cylinder filled with an aqueous foaming solution;

is the mass of the graduated cylinder filled with freshly formed foam.

Resistance was assessed as the time of complete disappearance of foam after uniform application of a layer of it on the surface of a grass lawn or a plasticized PVC floor covering modeling it.

As follows from the table. 1, foam formulations prepared using environmentally friendly, biodegradable surfactants and combinations thereof, according to Examples 1, 3, 5 and 7, yield abundant foam with controlled limited stability, consistent with the stated purpose and claims.
