From the manufacturer’s Safety Data Sheet, Section 8
“The safety data sheet lists no H315 or H317 at the mixture level and invokes the consumer-product exemption · individual fragrance components are undisclosed. Bergamot-citrus fragrance profiles commonly include linalool and limonene, IFRA-listed sensitizers at concentration, but presence in Black Ice is not confirmed. Direct handling of the pressboard is brief · unwrap and hang · and not an acute skin-exposure pathway. Individuals with known fragrance sensitivity may want to handle with care.”

From the manufacturer’s Safety Data Sheet, Section 8
“The safety data sheet records no respiratory H-codes (no H334, H335). Passive paper-card diffusion releases low-level fragrance continuously inside the enclosed vehicle cabin. No SDS-confirmed inhalation hazard; the situational tier reflects the rubric's standard pattern for fragrance-containing passive diffusers in an enclosed cabin and the possibility of an unidentified fragrance sensitizer.”

TL;DR The bestselling Little Trees scent, a genuine category favorite owners reach for again and again, with a 5·10 day real-world scent life rather than the Amazon "7 Days" spec. A cool, cologne-leaning profile. The manufacturer's all-scents safety data sheet classifies the product as exempt from hazard labeling under the consumer-product rule.
A fragrance-impregnated pressboard hanging card cut into the iconic tree silhouette and printed in black. Community owners describe the scent as masculine, cool, and cologne-leaning. Real-world evidence from a large owner base on the 10-pack root listing puts noticeable scent at 5·10 days: strong throw days 1·3, a baseline by day 5, barely detectable by day 10·14. Partial unwrap is the documented community technique for stretching useful life. Slightly more polarized than Royal Pine · most owners love the character, a vocal minority calls it synthetic.
Best for drivers who want a low-cost weekly scent change and like a cool, cologne-leaning character. Universal fit on any rearview mirror. Skip it if you want 30-day longevity, if the profile reads synthetic to you, or where the card could swing into a light dashboard or headliner · fragrance oil can stain on contact.
The manufacturer's all-scents safety data sheet classifies the product as exempt from GHS hazard labeling under the consumer-product rule (29 CFR 1910.1200(b)(6)). No signal word, no pictograms, no H-codes. SDS §11 states IFRA fragrance compliance. No California Prop 65 warning per SDS §15 and the listing cache. Passive paper-card diffusion at low emission rates; no aquatic-toxic ingredients flagged at the mixture level.
The product spec field says '7 Days' and the packaging says 'Lasts for weeks,' but broad community evidence from long-term reviews puts realistic noticeable scent at 5·10 days · strong initial throw in days 1·3, gradual fade, barely detectable by day 10·14. Partially unwrapping the card (exposing only the top half) is a documented community technique for extending effective life.
It is the bestselling Little Trees scent · described as a 'masculine,' bergamot-citrus-sandalwood blend with a cool/dark fragrance profile. Community owners describe it as cologne-like; opinion is somewhat polarized between 'pleasant' and 'synthetic.' Coverage fills the front cabin from the rearview mirror with a strong initial throw.
Yes · it is the manufacturer's generic all-scents document. Car-Freshner Corporation publishes a single SDS (filename: Little-Trees-Paper-Tree-Air-Fresheners-ALL.pdf) that explicitly covers Black Ice and every other Little Trees Paper Tree scent. The September 2019 revision classifies the product as exempt from GHS hazard labeling under the consumer-product rule (29 CFR 1910.1200(b)(6)) · no signal word, no H-codes, no hazardous components disclosed in reportable quantities, and IFRA fragrance compliance stated in §11.
Yes, if the card touches a surface. The product instructions state 'hang freely, avoid contact with any surfaces' · the fragrance oil can stain light-colored vinyl, leather, or fabric on contact. This is a documented community failure mode across all Little Trees variants. Hang from the rearview mirror with enough length that the card does not swing into the windshield or dashboard during driving.
The safety data sheet does not address pet exposure specifically. The product is classified as exempt from GHS labeling for human consumer exposure, but cats and small mammals are more sensitive to airborne fragrance compounds than humans. Hang the card away from sustained pet contact and ventilate the cabin between drives if a pet rides regularly.
