@fify-- I make homemade soap and I've tried making pine tar soap once. I did use some essential oils in it including lavender and it did change the scent slightly. But the pine tar scent was still very dominating and I think it has to be because the soap needs to be at least 15% pine tar in order for it to be effective for skin conditions like psoriasis. So no matter what you do, it's going to smell like pine tar to some degree.
And making pine tar soap at home is not easy. It cools down very quickly which makes it difficult to get it into the molds. This was my main problem when I tried to make it and I didn't get the best results. It also didn't lather as well as it should have. I have not tried making it again.
Perhaps there might be some pine tar soaps on the market with added essential oils or fragrances though.
