The Deodorant Olibanum vs Baking Soda Free Deodorant: which is safer?

Where these two actually differ

• We flag Heavy metals in mineral powder (lead, cadmium, arsenic), Formaldehyde-releasing preservatives in mineral blend, Microbial growth in powder container if moisture ingress occurs and Fragrance allergen undisclosed in 'olibanum' claim on the Necessaire and not on the Primally Pure.
• We flag Skin irritation from magnesium hydroxide alkalinity on the Primally Pure and not on the Necessaire.
• The Necessaire is mineral powder blend, container composition unspecified where the Primally Pure is mineral-based powder blend (arrowroot, magnesium hydroxide, mica), which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Primally Pure is the one to buy.
• We are less certain about the Necessaire grade, at 45% confidence against 82%, because it discloses less.
