What Aluna Stick Deodorant is made of, ingredients and materials
Aluna Stick uses potassium alum or ammonium alum salts, naturally occurring mineral compounds that work by forming a protective layer on skin and inhibiting bacterial growth without blocking sweat. These salts have been used in personal care for decades and are not synthetic chemicals. Unlike antiperspirants, alum deodorants do not contain aluminum chlorohydrate or other aluminum compounds designed to plug sweat ducts, reducing systemic absorption risk.
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.
Lead
Potassium and ammonium alum are mined minerals and can contain trace heavy metal contaminants depending on source and refining. Crystal has not published third-party heavy metal testing data for this product. Risk is lower than synthetic additives but unverified.
Source, ATSDR ↗Skin irritation or allergic contact dermatitis
Pure mineral salt deodorants are generally well-tolerated, but occasional contact irritation has been anecdotally reported in sensitive individuals. No formal adverse event database entries are on record for this specific brand, but irritation risk exists with any topical product.
Fragrance allergens (if scented variant)
If the product contains added fragrance oils or essential oils, these can trigger contact dermatitis or respiratory irritation in sensitive users. Crystal markets both scented and unscented versions; fragrance ingredient lists are not consistently disclosed.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Talc or talc-like mineral contaminants
Aluma Stick formulations typically do not include talc filler. However, if the product contains anti-caking agents or flow additives from the mining or processing stage, trace silicate minerals could be present. Brand does not detail secondary ingredients or processing aids.
Bacterial or mold growth in stick form
The mineral salt base and solid form inhibit microbial growth under normal storage. Risk is negligible if kept dry. No documented contamination incidents are on record for this product line.
How is this PFAS grade calculated?
The brand's record and disclosure
Crystal (owned by Coty Inc.) has maintained a minimal public stance on ingredient sourcing and third-party testing for this product line. The brand does not highlight certifications such as EWG Verified, Leaping Bunny, or NSF standards on marketed materials. No significant safety recalls or regulatory actions are on record for this specific deodorant, but the brand's silence on manufacturing controls and heavy metal testing of mineral salts limits independent verification.
How it compares in its category
Mineral salt deodorants sit at the lower-toxicity end of the deodorant spectrum, avoiding synthetic preservatives, fragrance blends, and antiperspirant actives found in conventional stick formulas. They carry less risk of allergic contact dermatitis than products with added botanicals or essential oils. However, they are less effective for heavy perspiration than antiperspirants and may feel less cosmetically elegant than talc-containing or silicone-based alternatives.
If you buy it
Store in a cool, dry place to prevent the stick from crumbling or absorbing moisture. The crystal will gradually wear down with use; replace when material becomes too small to apply comfortably, typically every 6-12 months depending on frequency. Wet skin slightly before application for even coverage and to reduce dust. If skin irritation or rash develops, discontinue use; pure mineral salts are well-tolerated but individual sensitivity is possible.
