No Safety Data Sheet on file.
CarCareTruth has not received a Safety Data Sheet from the manufacturer for this product, so no GHS hazard classification can be cited. The tiers below are cautious defaults — “Beyond SDS” — translated from the product’s ingredient chemistry and how comparable formulations classify, not from a manufacturer hazard classification. Request an SDS from the manufacturer before use.

Beyond SDS: translated from the ingredient chemistry
No SDS available; PPE tier estimated from product format. The gel cup is sealed during normal use, so skin contact only occurs if the gel is touched directly during disposal. Fragrance gel concentrates commonly contain skin sensitizers, but this cannot be confirmed without ingredient data.

Beyond SDS: translated from the ingredient chemistry
No SDS available; PPE tier estimated from product format. The passive gel-cup diffuser releases fragrance continuously into the enclosed cabin with no intensity control. No respiratory H-codes can be confirmed or ruled out. Individuals with fragrance sensitivity should monitor for respiratory reactions.

Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR A Japanese passive gel-cup with the cult Black Squash scent. No adjustable lid means no intensity control, and the 60-day label claim has no community backing yet. Health is 5.0 with a NO SDS badge · Sakura publishes no English safety documentation. Buyers broadly like the scent, but get zero visibility into the chemistry.
A thin upright cup of water-based gel that sits under a seat or in a door pocket and releases fragrance as the gel evaporates through a fixed opening. Black Squash is a sweet fruity-candy citrus blend · broadly liked and the main reason buyers pick this brand. The 60-day claim is provisional pending community data; with no lid, heat and sun drive duration. The container is single-use.
Best for drivers who specifically want Black Squash and are fine with a set-and-forget cup. Skip it if intensity control matters, if you prefer a refillable case, or if ingredient visibility matters at all.
No English-language SDS is available. Sakura does not publish safety documentation through Western repositories, and treefrogusa.com / treefrog.us do not resolve. The 5.0 health score reflects this gap · without SDS data, the fragrance chemistry cannot be evaluated for H-codes, sensitizers, or VOC content. The product listing confirms no Prop 65 warning, but no back-of-container image is available to cross-check the label. PPE tiers are estimated from format: the sealed gel cup presents minimal direct exposure in normal use, but fragrance compounds evaporate continuously into the enclosed cabin.
Squash is a Japanese fragrance category · it has nothing to do with the vegetable. owners describe Black Squash as a sweet, fruity-candy citrus blend with a slightly deeper, muskier base than the original Squash. It is the signature Treefrog scent and the reason most buyers choose this brand.
The product listing claims 60 days. Community-confirmed longevity has not been independently aggregated at depth, so this is treated as provisional. The container has no adjustable lid or intensity control, so duration is driven mainly by cabin temperature and sun exposure. Hot summer cabins will burn through the gel faster than cool, shaded placement.
No English-language SDS is publicly available. Sakura is a Japanese manufacturer that does not publish English safety documentation through standard Western SDS repositories, and the U.S. distributor sites (treefrogusa.com, treefrog.us) are non-functional. The absence of an SDS means the fragrance chemistry is undisclosed, which is why the health score is 5.0 with a NO SDS badge.
No. The Treefrog gel cup is a single-use, disposable container. When the gel runs out, the entire unit is discarded. This is a key difference from the refillable Air Spencer CS-X3 case system.
The thin upright container is intended for under-seat or door-pocket placement. It is not a vent clip and has no mounting hardware. Some owners note the cup can tip if it is not on a flat surface.
