Phlur is not a fully natural brand, but it positions itself as a cleaner alternative to conventional fragrances by combining botanical ingredients with what it calls “tested synthetics.” Whether that qualifies as “non-toxic” depends on how you define the term, since fragrance regulation is looser than most consumers expect and “non-toxic” has no legal standard in the beauty industry.
What Phlur Actually Puts in Its Products
Phlur uses a blend of botanical and synthetic ingredients. The brand is upfront about this: it is not 100% natural. Its reasoning is twofold. First, the company argues that natural doesn’t automatically mean safe or sustainable. Some botanical extracts are more allergenic than their synthetic counterparts. Second, Phlur says synthetics give perfumers a wider creative palette and can protect endangered plant species that would otherwise be overharvested for fragrance production.
This approach is common among brands that market themselves as “clean” fragrance. Rather than eliminating synthetics entirely, they claim to screen out specific chemicals of concern while keeping lab-made ingredients that pass their safety standards. The key question for consumers is how rigorous that screening actually is and who’s doing the evaluating.
What “Non-Toxic” Means in Fragrance
There is no regulated definition of “non-toxic” in the fragrance or cosmetics industry. The FDA does not require fragrance companies to disclose individual scent ingredients, and terms like “clean,” “non-toxic,” and “safe” are marketing language, not certifications. A brand can use these words without meeting any specific chemical threshold.
What most people mean when they search for non-toxic fragrance is: does this product avoid the chemicals I’ve heard are harmful? Common concerns include phthalates (used to make scent last longer), parabens (preservatives), and certain synthetic musks. Phlur’s marketing suggests it avoids many of these, but the absence of a standardized restricted-substance list makes it difficult to compare one “clean” brand to another without reading individual ingredient labels.
Phlur’s Cruelty-Free Status
Phlur was previously certified by Leaping Bunny, the most recognized cruelty-free certification program. However, the brand appeared on Leaping Bunny’s list of companies that did not recommit in 2020. This means Phlur’s cruelty-free certification lapsed, and its current animal testing status is not independently verified by that organization. The brand still markets itself as cruelty-free on its website, but without active third-party certification, that claim relies on the company’s own word rather than external auditing.
This distinction matters if cruelty-free status is part of what “non-toxic” or “ethical” means to you. Leaping Bunny certification requires companies to recommit regularly and submit to independent audits of their entire supply chain, including ingredient suppliers. Without that recommitment, there’s no outside party confirming that no animal testing occurs at any stage of production.
Synthetics Are Not Automatically Harmful
One nuance worth understanding: synthetic ingredients in fragrance are not inherently dangerous. Many lab-created molecules are identical to compounds found in nature, just produced in a controlled environment rather than extracted from plants. Some synthetic ingredients have been studied more thoroughly than their natural equivalents, and certain botanicals (like some essential oils) can cause skin sensitization, phototoxicity, or allergic reactions at high concentrations.
Phlur leans into this point, stating that synthetic ingredients “can be less allergenic than certain natural ingredients.” That’s a scientifically accurate claim in general terms. Lavender oil, citrus extracts, and cinnamon-derived compounds are all natural and all common allergens. A fragrance built entirely from botanicals is not necessarily gentler on your skin than one using well-tested synthetics.
The real concern with conventional fragrance isn’t synthetics as a category. It’s specific chemicals, like certain phthalates linked to hormone disruption, or formaldehyde-releasing preservatives, that have raised health flags in research. A useful question isn’t “is this natural or synthetic?” but rather “which specific ingredients does this brand exclude, and why?”
How to Evaluate Phlur for Yourself
If you’re trying to decide whether Phlur meets your personal standard for safety, a few practical steps help. Check the ingredient list on the specific product you’re considering, not just the brand’s general claims. Phlur does publish ingredient lists, which puts it ahead of many fragrance companies that hide behind “proprietary blend” language.
Look at databases like the Environmental Working Group’s Skin Deep or the Think Dirty app, where individual products are scored based on ingredient safety data. These tools aren’t perfect, but they give you a reference point beyond marketing copy. Pay attention to whether a product lists known sensitizers like linalool or limonene, which are common in both natural and synthetic fragrances and are required allergen disclosures in the EU though not in the United States.
If you have sensitive skin or fragrance allergies, patch testing any new perfume is more reliable than relying on a brand’s “clean” label. Apply a small amount to your inner wrist and wait 24 hours before using it more broadly. No ingredient philosophy, natural or synthetic, guarantees you won’t react to a specific product.
