I don't mean to sound like a pleb, but the biggest lesson of the past two centuries is how much people bluff, use the name of 'science, progress, blah blah' to push for their own profits, regardless of actual consequences (bodily or environmentally or ecologically).
I generally stick to old-school goods that are totally natural, cheap and are still massively produced in India. With the 'generic' stuff, half the shit is made from tortured-killed cows (urgh vomits) (admittedly, this is mostly outside India), and all of them are filled with god knows what, and made from god knows what.
If you're India, check out Patanjali's ash and lime dishwasher soap that cost like Rs. 20 per bar. Shout out to FitTuber on Youtube who reviews a lot organic products from India.
