SECTION 4: First aid measures
Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound include skin sensitivity reactions, contact dermatitis, urticaria and angioedema. It can cause skin and eye irritation. Dilute solutions of this type of compound may be painful and cause irritation when applied to the eye. ACUTE/CHRONIC HAZARDS: This compound is a skin and eye irritant. When heated to decomposition it emits acrid smoke, irritating fumes and toxic fumes of carbon monoxide, carbon dioxide and phenolic vapor. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Poisons A and B

Persistence and degradability
AEROBIC: Butylparaben may readily biodegrade in the environment based on the biodegradation data of the structurally-similar compound, methylparaben(SRC). Using a Zahn-Wellens test, which requires a 0.2 - 1.0 g/L dry inoculum and 50-400 dissolved organic carbon/L test concentration(1), methylparaben degraded 100% after 6 days with a 2 day acclimation period in a sludge inoculum(2). Average concentrations of 0.86, 0.04, 0.28 and 0.04 ng/L were reported for butylparaben in gray water from 32 residences and associated effluent from aerobic, anaerobic and anaerobic+aerobic biological treatment systems, respectively. Testing was done in August, 2008 in Sneek, The Netherlands. Butylparaben removal was postulated to be a combination of adsorption and biodegradation, with a 95.3% removal observed using aerobic treatment(3). Butylparaben, present at an average concentration of 140 ng/L, exhibited half-lives of 2.9 days and 9.6 hours using an activated sludge batch test and a real wastewater treatment plant test, respectively; sampling was conducted during April and May 2010 in a metropolitan area of northwest Spain(4).
Bioaccumulative potential
An estimated BCF of 100 was calculated in fish for butylparaben(SRC), using a log Kow of 3.57(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of butylparaben can be estimated to be 520(SRC). According to a classification scheme(2), this estimated Koc value suggests that butylparaben is expected to have low mobility in soil. The pKa of butylparaben is 8.47(3), indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
