February 25, 2026 — A consumer has reported a severe systemic allergic reaction, including a significant drop in blood pressure, after using a new formulation of Tide Free laundry detergent. The individual attributes the reaction to the addition of Benzisothiazolinone, a preservative, which they were unaware had been introduced into the product.
Product Details
Product: Tide
Incident Overview
The consumer reported experiencing a systemic allergic reaction with a continuous drop in blood pressure over three days after using a new formulation of Tide Free laundry detergent. The individual, who identifies as sensitive, began using the product approximately two weeks prior to the incident report, with symptoms manifesting about four days before reporting. Through personal research, the consumer discovered that Benzisothiazolinone, a preservative, had been added to the detergent’s formula. The consumer stated they were unaware of this change as their new bottle of detergent did not bear a “new formula” label. Had they been aware, they would have researched the added preservative due to their sensitivities. The incident highlights potential issues with communication of formula changes for products marketed towards sensitive individuals.
Safety Concerns
The reported incident involving Tide Free detergent raises several safety concerns, particularly for individuals with chemical sensitivities or allergies:
- Immediate Dangers: A systemic allergic reaction, as reported, can be severe. A significant drop in blood pressure (hypotension) can lead to dizziness, fainting, shock, and, in extreme cases, be life-threatening, potentially requiring emergency medical intervention. Other systemic allergic symptoms could include widespread rash, swelling, difficulty breathing, or anaphylaxis.
- Long-Term Risks: Repeated exposure to an allergen can lead to increased sensitization, making future reactions more severe or persistent. Individuals might develop chronic dermatological issues or respiratory problems if exposure continues unknowingly.
- Who Might Be Affected: This incident primarily affects individuals with sensitivities or allergies to specific chemical ingredients, particularly preservatives like Benzisothiazolinone. Consumers who rely on “free and clear” or “sensitive skin” formulations expect these products to be free from common irritants and allergens. Lack of clear labeling for formula changes can put this vulnerable population at significant risk.
- Property Damage Potential: This incident does not pose a direct risk of property damage.
What Consumers Should Do
Consumers, especially those with known sensitivities, should take the following actions:
- Immediate Steps: If you experience any allergic reaction, skin irritation, or systemic symptoms (like a drop in blood pressure, difficulty breathing, or widespread rash) after using a new or unfamiliar laundry detergent, discontinue use immediately. Seek medical attention if symptoms are severe or persistent.
- Check Your Product: If you use Tide Free or other “free and clear” detergents, carefully check the ingredient list on your bottle. Be vigilant for specific preservatives like Benzisothiazolinone. Manufacturers may update ingredient lists on their websites (e.g., via SmartLabel) before labels on physical products are updated.
- Prevention Measures:
- Always read ingredient labels, even for products you’ve used for years, as formulations can change without prominent “new formula” warnings.
- For highly sensitive individuals, consider doing a small patch test with new detergents on a piece of fabric or a small, non-sensitive area of skin before full use.
- Opt for detergents specifically certified by dermatologists for sensitive skin if possible.
- Reporting Procedures: If you or someone you know has experienced a similar allergic reaction or adverse event due to a consumer product, report it to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report helps identify potential hazards and prompts further investigation.
Manufacturer’s Response
On February 6, 2026, The Procter & Gamble Company (P&G) provided a response to the incident report. P&G thanked the consumer for contacting the CPSC, expressed regret for the experience, and affirmed Tide’s dedication to providing safe products and taking such reports seriously.
P&G stated that they routinely investigate product complaints to ensure their processes maintain high quality standards and that the incident report was shared with their Health & Safety and Tide Teams. They acknowledged that while all Tide ingredients and products are thoroughly evaluated for safety and effectiveness when used as directed, some individuals may have personal sensitivities.
P&G recommended discontinuing product use and seeking medical attention if symptoms worsen or do not resolve. They also directed consumers to SmartLabel.org for ingredient lists, noting that the presence of Benzisothiazolinone in the Tide formulation is available there and has been public information since its introduction in 2024. P&G concluded by appreciating the outreach and wishing the consumer well.
