4First-aid measures

First Aid Measures

Inhalation: Move the person to fresh air and keep comfortable for breathing. If breathing is difficult or symptoms persist, call a POISON CENTER or doctor.
Skin: Take off contaminated clothing. Wash the skin with plenty of soap and water. If irritation or a rash develops, get medical advice.
Eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do; continue rinsing. If eye irritation persists, get medical advice.
Ingestion: Rinse mouth. Do not induce vomiting. Call a POISON CENTER or doctor if you feel unwell.

Most Important Symptoms And Effects

No specific symptoms are known. Pharmacologically active material: systemic effects consistent with its mechanism of action are possible after accidental injection, ingestion or absorption.

Likely Routes Of Exposure

Ingestion; inhalation of dust and skin/eye contact if capsules are opened.

5Fire-fighting measures

Fire Fighting Information: Combustible organic solid; capsule contents may form combustible dust if dispersed in bulk.

6Accidental release measures

Spill And Clean Up Procedures: Collect intact capsules. Dampen any spilled powder with water, wipe up with absorbent material and place in a sealed container for disposal.

7Handling and storage

Safe Handling: Do not open or crush capsules unless required for an experiment; if capsule contents are handled as a powder, avoid generating dust and weigh inside a ventilated enclosure. Wash hands after handling.
Safe Storage: Store at room temperature (15–25 °C) in the tightly closed original container, dry and protected from light.
Storage Temperature: 15–25 °C, dry, protected from light
Incompatible Materials: Strong oxidizing agents (generic for peptides)

8Exposure controls / personal protection

Occupational Exposure Limits: Microcrystalline cellulose: OSHA PEL 15 mg/m³ (total dust), 5 mg/m³ (respirable fraction); ACGIH TLV 10 mg/m³ (as cellulose).

No occupational exposure limits have been established for the active ingredient(s).
Exposure Controls And PPE: No data available.

13Disposal considerations

Disposal Guidance: No data available.

14Transport information

Transport Classification

Note: Not regulated as a dangerous good for transport by road (DOT 49 CFR), air (IATA/ICAO) or sea (IMDG). Not a marine pollutant. Ship refrigerated or frozen as required by Section 7; the coolant (dry ice, UN 1845) is regulated when used.

15Regulatory information

Regulatory Information

Tsca: Not listed
Carcinogen Listings: Not listed (IARC, NTP, OSHA, EPA)
Dea: Not a controlled substance
Other: WADA remark: Ac-SDKP is the N-terminal tetrapeptide of thymosin beta-4; WADA S2 prohibits 'thymosin-beta4 and its derivatives (e.g., TB-500)' - Ac-SDKP is not named, but note the relationship.
