Embodiment 1

[0049] Example 1 illustrates the antimicrobial properties of an ester of rosin.

Embodiment 2 to 8

[0050] In Examples 2 to 8, the microbicidal effect of the antimicrobial composition of the present invention was measured according to the EN13697 standard, which relates to a quantitative surface test for the evaluation of the biocidal properties of chemical disinfectants used in food, industrial, domestic and institutional areas. antibacterial and / or fungal activity. The strains of bacteria, fungi and molds tested meet the relevant standards. For each microorganism tested, the colony forming units (cfu) per ml (N) of the test suspension and the microbicidal effect of the test substance (N a ). According to this standard, a good microbicidal effect is a log4 microbial reduction for bacteria and a log3 microbial reduction for fungi.

[0051] Example 1

[0052] figure 1 Contains naturally occurring coniferous resinous acid and monopropylene glycol (monopropylene glycol) The gas chromatogram (liquid-gas chromatogram, LGC) of the acetone extract of laquer. A known Laquer...

Embodiment 2

[0057] A 1% A12t ethanol solution prepared from spruce resin, a control solution and a standard solution were tested for microbicidal effect on a steel test panel. The reaction time of the sample on the plate is 24 hours. The results are given in Table 1.

[0058] The meaning of the sample number is as follows:

[0059] 0 = A12t ethanol (control)

[0060] 1=A12t ethanol solution of one percent spruce resin (the present invention)

[0061] 2 = Surgical hand sanitizer (standard)

[0062] 3 = clean iron plate (test plate).

[0063] Surgical Hand Sanitizer contains cetyltrimethylammonium chloride, which is classified as a skin irritant and a health hazard if swallowed.

[0064] Table 1

[0065]

[0066] The results showed that denatured alcohol did not provide long-term protection against microbes. Standard samples provided good protection against all bacteria except enterococci. The composition of the invention provided a good long-term protective effect against all ...

Abstract

The invention relates to an antimicrobial composition containing coniferous resin acids and / or their derivates. The invention also relates to an antimicrobial polymer composition comprising coniferous resin acids and / or their derivates and processes for preparing thereof. The invention also relates to the use of the derivates of coniferous resin acids as an antimicrobial agent.

Description

technical field [0001] The present invention relates to an antimicrobial composition containing coniferous resinic acid and / or derivatives thereof. The present invention also relates to antimicrobial polymer compositions comprising coniferous resinic acid and / or derivatives thereof. [0002] The present invention also relates to the use of coniferous resin acid derivatives as antimicrobial agents. Background technique [0003] For centuries, asphalt has been used to protect the bottom hull and deck structures of boats and boats. Later, the growth of barnacles on the bottom of boats and boats was prevented by the use of antifouling paints prepared from substances containing heavy metals. However, these things are now considered harmful to the environment, so they are being or will soon be banned. Barnacles on the bottom of boats and boats hinder the movement of the boat, thus causing an increase in cost and environmental load. The European Union has also restricted the us...
