OST-free™ excludes everything non-toxic and clean lines exclude; plus all known additives and ingredients ranked with organ system toxicity concerns by EWG regardless of risk.
OST-free™ qualify additives and ingredients based on independent research, EWG's concerns, and manufacturer's INCI. The actual composition of each additive or ingredient is not a qualifying factor.
OST-free™ provides superior skincare with ingredient quick-links to a credible resource that specializes in providing the public with information regarding toxicity.
OST-free™ is not non-toxic or clean. Our stand is there is no way to truly be non-toxic and the term clean is commonly perceived as non-toxic. Instead, we claim OST-free™ as there are many unknown factors that can change the composition of any ingredient (or additive) from synthesis; to your application.
For example; on a mass market level; formulating L-ascorbic acid (vitamin C) in a water-based solution visibly demonstrates changes occur, in many cases, formulas perceived as well-formulated are oxidizing before first use.
OST-free™ simply means nothing is intentionally added to an OST-free™ formula that has been flagged with organ system toxicity concerns through EWG.
