Schwarzkopf OSiS Freeze Finish 2 Strong Hold
Lower concern; typical aerosol hair spray with no known PFAS red flags, but no transparency.
Schwarzkopf OSiS Freeze Finish 2 is a standard ethanol-based aerosol hair spray. No evidence of Teflon-family coating coatings, waterproofing treatments, or stain-resistance additives that would typically introduce PFAS.

The full breakdown
What it's made of and why it matters
OSiS Freeze Finish 2 is an ethanol-based aerosol spray containing polymeric resins that form a flexible film on hair to provide hold. Ethanol is a volatile organic compound that evaporates quickly after application, carrying minimal systemic risk at typical use volumes. The polymeric resin (likely acrylate or vinyl-based) deposits on the hair shaft and does not absorb into skin in meaningful amounts during normal styling use. Propellant aerosol systems in this product class typically use hydrocarbons or compressed gases rather than ozone-depleting or high-toxicity alternatives.
The brand's record and disclosure
Schwarzkopf (owned by Henkel) has not published detailed ingredient transparency or third-party safety certifications for this specific product line. The brand maintains general compliance with EU and US cosmetic regulations but does not disclose PFAS-avoidance policies or independent testing records for aerosol propellants. No recalls or safety controversies specific to OSiS Freeze Finish 2 are on public record. Schwarzkopf markets this as a professional-grade product but offers limited ingredient-level disclosure beyond regulatory minimums.
How it compares in its category
Aerosol hair sprays occupy a middle ground for transparency: they avoid some hazards common to cream or gel formulations (like preservative allergens) but introduce inhalation exposure risk typical of all sprays. OSiS Freeze Finish 2 is positioned in the professional/salon tier, which generally implies stricter formulation standards than mass-market drugstore equivalents, though not necessarily higher ingredient disclosure. Alcohol-based aerosol sprays like this are considered lower-risk than those relying on heavy silicones or undisclosed fragrance blends. Competitors in the strong-hold aerosol category (e.g., Tresemmé, TRESemmé) show similar transparency gaps.
If you buy it
Use in well-ventilated spaces to minimize ethanol vapor inhalation; do not spray near face or inhale directly. Keep away from heat sources and open flame, as the aerosol propellant is flammable. Store at room temperature and do not puncture the canister. Discontinue use if scalp irritation or contact dermatitis develops; rinse hair thoroughly with water if product contacts eyes. Replace when spray weakens or nozzle clogs; do not attempt to refill or disassemble the canister.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Inhalation exposure (ethanol vapor and propellant aerosol)
Aerosol application releases ethanol vapor and fine mist particles into the breathing zone. Acute inhalation at high exposure (e.g., in poorly ventilated spaces or repeated daily use) may cause mild respiratory irritation; chronic occupational exposure in salons is a recognized concern but not documented as a hazard at consumer-use frequencies.
Eye irritation from spray contact
Ethanol-based aerosol sprays commonly cause temporary eye stinging and redness on direct contact; this is a known use hazard for all hair sprays in this formulation class and is manageable through application technique and immediate rinsing.
Formaldehyde releasers in polymeric resin or preservatives
Schwarzkopf does not disclose the specific polymeric resin or any preservatives in this product; formaldehyde-releasing resins are not typical in modern aerosol hair sprays, but absence of ingredient detail prevents full confirmation.
Heavy metals in fragrance or colorants
No specific fragrance allergens, azo dyes, or heavy metal contamination has been reported for OSiS Freeze Finish 2; the product is uncolored and fragrance composition is not disclosed, so trace contamination cannot be ruled out without independent testing.
Skin contact dermatitis (scalp and hands)
Ethanol is a known irritant and dehydrant to skin; prolonged or frequent hand contact may cause dryness or contact irritation. Scalp irritation is rare but possible in individuals with sensitive skin or pre-existing dermatitis, particularly if applied directly to skin rather than hair only.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
