From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H319 (eye irritation Cat 2) but no H318 and no DANGER from an eye-pathway code (DANGER is driven by H225 flammability). Per glass-coating rubric v2.0: H319 without H318 and without eye-driven DANGER → situational tier. The wipe-on felt-applicator format keeps direct eye contact unlikely except through deliberate splash or rubbing eyes mid-application.”

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H225 + H336 driven by the propan-2-ol carrier at 91–96%, but does NOT classify H314 or H315 at the mixture level (trace HCl falls below its 25% specific concentration limit). Per glass-coating rubric v2.0 §Skin trigger (b): high-alcohol carrier ≥ 70% with H225 + H336 and no H315 → situational with `prolonged_or_repeated` trigger. The chemistry concern is defatting from prolonged or repeated dermal contact with the IPA carrier, not acute irritation or corrosion. Nitrile gloves are appropriate when applying multiple bottles in succession or working without breaks.”

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H336 (STOT SE Cat 3, CNS narcosis) from the IPA vapor. SDS §2 does NOT classify H335 (respiratory irritation), H330, H331, or H334. Estimated working VOC > 700 g/L from the 91–96% IPA carrier — typical home-garage application produces vapor concentrations where the H336 narcosis threshold becomes relevant in an enclosed space. Outdoor application or open-garage work avoids the trigger. Per glass-coating rubric v2.0 §Lungs: H336 without H335 → situational with enclosed_space trigger.”

CarCareTruth's Analysis
Last reviewed May 25, 2026
TL;DR Ultra Glaco bonds a fluorine-based water-repellent to the windshield and lasts 6–10 months on a daily driver, with highway sheeting forceful enough to qualify as coating-tier performance. The integrated felt-tip applicator makes it the easiest product to apply in the Glaco family, though the high-alcohol carrier drives a DANGER signal word — work outdoors or with the garage door open.
What it is and how it performs
Ultra Glaco is the 12-month coating-grade member of Soft99's Glaco family, distinct from the 3-month Glaco Roll On topical repellent. The fluorine-based active bonds chemically to the glass, so durability runs months rather than weeks. Press the integrated felt tip against clean dry glass, wipe in overlapping strokes, let it haze, then buff — no separate pad, no spray-misting variable. Community data puts realistic durability at 6–10 months on a daily driver. Wiper chatter is not a category-defining issue here.
Who should buy this — and who should skip it
Best for buyers who want a single quick application that lasts most of a year and prefer to skip the spray-and-applicator-pad workflow common to other glass coatings. Skip it if PFAS would be disqualifying — partial-confidence status means the fluorinated active is unresolved, and a future confirmation would categorically downgrade environment. Gtechniq G1 is the non-PFAS alkoxysilane alternative at 12–18 months.
Safety and environmental impact
SDS Section 2 classifies H225 (flammable liquid Cat 2), H319 (eye irritation Cat 2), and H336 (CNS narcosis Cat 3), driven by the propan-2-ol carrier at 91–96%. The DANGER signal word reflects both the flammability and the health classifications — keep the bottle away from open flame and apply outdoors or with the garage door open. No H314, no H315, no H318, no H334 — no PPE category reaches the required tier. PPE skin is situational with a prolonged_or_repeated trigger because the high-alcohol carrier defats skin on extended contact. The fluoroalkyl-silane active is not disclosed in SDS Section 3, and PFAS status is flagged partial pending corporate or patent confirmation.
Frequently asked questions
How long does Soft99 Ultra Glaco actually last on a daily-driven windshield?▾
Community data on Detailing World, r/AutoDetailing, and YouTube long-term tests puts realistic durability at 6-10 months on a daily driver, with visible beading falling off noticeably by 12 months. The 'up to 12 months' label claim is on the optimistic end of the community range but within the 25% gap threshold the quality rubric accepts. Wash frequency, wiper use, and climate all affect realized durability.
Does Ultra Glaco contain PFAS?▾
Status is partial — flagged contains_pfas: false pending confirmation. The 2018 SDS does not disclose a fluorinated CAS in Section 3 (the active sits below the 1% disclosure threshold or is proprietary), and the §2 mixture-level classification is fully accounted for by the IPA carrier plus trace HCl with no PFAS-specific hazard codes. Soft99 marketing describes a 'fluorine-based water-repellent,' which is ambiguous — some modern fluorosilanes are short-chain non-PFAS. Without a patent reference or corporate confirmation, the conservative call is partial confidence, not a definitive flag in either direction.
Will Ultra Glaco cause wiper blade chatter?▾
Wiper chatter is not a category-defining issue for Ultra Glaco the way it is for Aquapel or for some IPA-heavy alkoxysilane products. A small number of forum posters report mild break-in chatter resolving within a few wiper cycles. No persistent-chatter pattern is documented across the community sources reviewed. Checking wiper blade condition before application is still reasonable practice.
How does Ultra Glaco compare to the Glaco Roll On (3-month) sibling?▾
Different durability tier, different chemistry persistence. The Roll On is Soft99's 3-month topical repellent (categorized under rain-repellent on this site). Ultra Glaco is the 12-month coating-grade product with the fluorine-based active that bonds to the glass surface itself. Pay more, apply less often. If you want a quick top-up between full coatings, the Roll On is the right tool; if you want a single application that lasts most of a year, this is.
Why is the SDS from Soft99's EU distributor, not the US importer?▾
Soft99 manufactures in Osaka and ships a single global formulation. The most accessible English-language SDS comes from Nowy Samochód S.A., Soft99's EU authorized distributor in Warsaw — an EU CLP-format document rather than a US OSHA HazCom 2012 SDS. The H-codes, ingredient disclosures, and signal-word classifications carry over to the US 70 ml SKU 10310 bottle because the formula is the same.
