This seems to be an Asian-English thing- calling flux "soldering paste" or even "solder paste". Sometimes the word "cream" is in there.
I've seen it in China, Hong Kong and Taiwan, and this "soldering paste" is from the Philippines.
Here is some Asian-origin (real) solder paste:
As you can see, the alloy (Tin 63%/Lead 37%) is specified as well as the ball size 25-45um diameter. Most lead-free alloys are mostly tin, with a bit of
copper and possibly other metals mixed in. There is a tin-bismuth alloy for the big spenders. It looks like a grey paste and under the microscope you can easily see that it is composed of tiny balls in a matrix of flux.
What you have is flux of some unknown type (although it's specified as non-corrosive so at least it (probably) isn't the typical highly acidic plumber's flux). You can stick multimeter probes into it and see if it is conductive.
Typical classes of fluxes are RMA (Rosin mildly activated), "no-clean" and water soluble. They have different characteristics, though for non critical circuits it may not matter which is used.
Here is a typical flux (RMA) from the same manufacturer:
As you can see, it's a translucent gel-like material with a yellowish tint, not dissimilar to what you have (however given the reference on the can to 'torch' I would be reluctant to try yours on circuits - it may be similar but have impurities that would be electrically conductive, for example).

Edit: From the comment/link by @JRE, the flux you have is claimed to be suitable for electronics:
"Noisy set" indeed. If you use acid flux at mains voltage (as a hapless customer of mine once did) the "set" will be noisy from all the electrical arcing.
