Rahua Voluminous Shampoo
Lower concern; liquid shampoo lacks common PFAS application categories.
Liquid shampoos without nonstick coatings, water-resistant treatments, or greaseproofing typically don't require PFAS. The brand doesn't publicly disclose PFAS absence or presence.

What Rahua Voluminous Shampoo is made of, ingredients and materials
Rahua Voluminous Shampoo is a liquid aqueous cosmetic formulation marketed with plant-derived and natural ingredients, including coconut oil and rahua oil. Liquid shampoos in water-based form present lower inherent risk for volatile organic compound off-gassing compared to powders or anhydrous cosmetics. The viscosity and packaging (typically sealed plastic or glass bottle) minimize exposure to degradation pathways that accelerate leaching of additives.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Fragrance allergens and essential oils
Rahua markets botanical fragrance and essential oil content as a brand signature. Undisclosed fragrance compounds and concentrated plant extracts (e.g., citrus oils, floral essences) can trigger contact sensitization, allergic scalp dermatitis, or photosensitivity in susceptible individuals; no public ingredient list or allergen warning is routinely provided by the brand.
Preservative system adequacy
Natural and premium shampoos often reduce synthetic preservatives (e.g., parabens, phenoxyethanol) in favor of plant-derived alternatives with lower documented efficacy. Insufficient or unstable preservative systems increase risk of bacterial or mold growth in the bottle or after opening, particularly if the product sits in a damp bathroom environment for weeks.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No recalls or test data are publicly available for Rahua Voluminous Shampoo concerning lead, cadmium, or arsenic contamination in plant-derived ingredients. Risk is not documented for this specific product, though botanical cosmetics sourced from unregulated agricultural regions can accumulate trace metals; brand does not disclose sourcing or heavy-metal testing.
Source, FDA ↗Formaldehyde / VOCs
Liquid shampoos formulated with botanical and plant-based preservatives are unlikely to rely on formaldehyde-releasing agents (e.g., imidazolidinyl urea, DMDM hydantoin), which are more common in mainstream mass-market products. No public disclosure or regulatory finding suggests Rahua uses these compounds; risk is assessed as low based on brand positioning.
Source, ATSDR ↗Microplastic particulates
Rahua Voluminous Shampoo is a liquid formulation without reported polyethylene microbeads or synthetic scrubbing particles. Microplastic risk is not a documented concern for this product, though it is relevant to some exfoliating or 'beads' shampoos in the market.
How is this PFAS grade calculated?
The brand's record and disclosure
Rahua is a smaller, premium natural beauty brand with no recorded safety recalls or regulatory actions on file. The brand does not publicly disclose detailed ingredient sourcing, manufacturing certifications, or third-party safety testing, though it markets itself as 'natural' and 'plant-based.' No public controversies regarding contamination, mislabeling, or banned substance use are documented. Certification status (organic, cruelty-free, etc.) should be verified on the product label or brand website if those factors influence your choice.
How it compares in its category
Liquid shampoos as a category carry lower documented risk profiles than solid bar cosmetics or powdered formulations, which can concentrate impurities or harbor bacterial growth if stored improperly. Premium and 'natural' brands like Rahua typically face higher consumer scrutiny and marketing incentive to avoid high-risk additives (e.g., formaldehyde releasers, heavy-metal pigments), though this does not guarantee independent lab verification. Most mainstream liquid shampoos share similar hazard profiles; Rahua's main differentiation is price and ingredient narrative rather than safety advantage or disadvantage.
If you buy it
Store the product in a cool, dry location away from direct sunlight and heat to prevent accelerated ingredient breakdown or emulsion separation. Keep the bottle sealed when not in use to prevent water ingress or microbial colonization, particularly important for preservative-light or 'natural' formulations that may have shorter shelf life than conventional brands. Use within 12 months of opening; discard if the product shows discoloration, separation, or odor change. Perform a small patch test on skin or scalp first if you have a history of fragrance or botanical sensitization.
