• Reactivity: 0 

• Special: 0 

• 0 = minimal 1= slight 2=moderate 3= serious 4= severe 

Route(s) of Entry 

• Inhalation: No inhalation hazard identified from data available. 

• Skin Contact: May cause irritation and reddening; rinse skin with water. 

• Ingestion: No adverse effect expected. 

• Eye Contact: May cause irritation or reddening. 

Effects of Overexposure: Contact with the eyes may cause irritation. Ingestion will cause mouth, throat and gastrointestinal irritation. Inhalation of harmful levels of vapors is unlikely due to the relatively low vapor pressure and the relatively low concentrations of ingredients. 

Acute Effects of Overexposure: None known. 

Chronic: None known. 

Medical Conditions Generally Aggravated by Long-Term Exposure: None expected. 

Chronic Effects: None known 

Carcinogenicity:

• NTP: None known 

• IARC Monographs: None known 

• OSHA Regulations: None known 

• ACGIH: None known 

Component: Polydimethylsiloxane
