I consider it science-based. She researched the choice of oil based on the underlying polymer chemistry and gave a taste of that research. The article also contains a lot of opinions that are not, or probably not, based on science. But "science-based" is sort of like "based on a true story": some liberties are acceptable. Moreover, I think the article is fairly scientific in spirit. When she had to make judgment calls, she described how and why she chose the option she did. A scientific research article doesn't have to settle every question it raises and do every possible experiment. It just needs to be clear about what it did and didn't do.
