COMPOSITION FOR FOOTBALL DISAPPEARING FOAM Russian patent published in 2020 - IPC C09K3/30 C09D5/29 A63B71/02 

FIELD: chemistry; sport.

SUBSTANCE: invention relates to a foaming composition used as a marker for marking sports fields. Foaming composition contains a) sodium, potassium, ammonium or amine salt of monocarboxylic acids C₈-C₁₈, including fatty acids, of which at least 10 wt % are coconut or palm kernel oil acids, b) surfactants from C₈-C₁₂ alkylpolyglucosides, C₈-C₁₂ alkylmethyl glucamides, c) acid salt, having complexing capacity with respect to hardness salts, d) water with an additive of an organic solvent selected from ethanol, propanol, butanol, propylene glycol, with the following content of components, wt %: a:b:c:d=(0.2–2.0):(0.05–1.0):(0.05–0.5):(rest is up to 100.0), where total content substances in terms of dry content in foam-forming composition does not exceed 3.5 wt %. Composition can additionally include essential oils in amount of 0 to 0.5 wt %, organosilicon component, selected from dimethicone, cyclomethicone, dimethiconol or a mixture thereof in amount of 0 to 0.5 wt % and preserving agents selected from parabens, 2-isopropyl-5-methylphenol, 4-isopropyl-3-methylphenol or mixtures thereof in amount of 0.05 to 0.2 wt %.

EFFECT: technical result is providing a foaming composition using a combination of surfactants based on renewable, biodegradable natural raw material and components, regulating resistance, multiplicity and dispersion of foam used as markers for marking of sports grounds, in particular football fields, in temperature range from +40 to 0 °C.
