Why it earns a place

Plaine Products explicitly excludes phthalates from the current shampoo line, publishes the complete base formula, and lists Unscented as having no added scent ingredients.

Phthalate assuranceExplicit claim + transparent formula

What backs the claim

The current shampoo page explicitly excludes phthalates, publishes the complete base formula, and says the Unscented option adds no scent ingredients. The exact 16-ounce no-pump refill is an available one-time purchase.

What it does not prove

The evidence comes from maker disclosure rather than a public quantitative test of the finished product. Reviews are pooled across shampoo scents and configurations, and botanical ingredients can still be individual irritants or allergens.
