Ingredient-specific information
Documented in sourceThe base’s reported pH tolerance of 2–12 is not a stability study of an incorporated active. This particular formula is pH 5–6.
References: [1]
Personal protective equipment
Partial evidenceComplete formula-specific PPE is not specified. Select gloves, eye protection and exposure controls using the exact materials’ SDS and the local risk assessment.
Supplementary AEMPS framework: clean long-sleeved laboratory clothing, hair covering and dedicated footwear/overshoes. Powder handling requires suitable eye/respiratory protection; change gloves with activity or damage. Select the exact type/material using SDS and risk assessment.
Risks and precautions
Partial evidenceA complete formula-specific hazard classification is not established. Assess potency, dust/aerosol, allergens, solvents, microbial risk and cross-contamination using the actual materials and process. Absence of a flag does not establish absence of hazard.
