Introduction to TRA Certification Testing

Testing standards

TRA certification, also known as toxicological risk assessment of cosmetic ingredients, aims to comprehensively evaluate the potential risks of cosmetic raw materials and finished products to human health, and ensure the safety of consumer use. TRA certification testing follows a series of strict standards and specifications:

Raw material safety assessment: Conduct in-depth analysis of each raw material used in cosmetics to evaluate its toxicological characteristics, including acute toxicity, subchronic toxicity, chronic toxicity, skin irritation, eye irritation, sensitization, etc. For example, through animal experiments or in vitro substitution tests, determine whether the raw materials will cause irritation or allergic reactions to the skin, eyes, etc. At the same time, refer to international authoritative databases and literature to understand the safety data of raw materials at different usage concentrations.

Exposure assessment: Calculate consumers' exposure to various ingredients in cosmetics based on their usage patterns, frequency, and quantity. For example, for applied cosmetics, consider their residence time and absorption on the skin surface; For spray cosmetics, evaluate their deposition in the respiratory tract. Determine the actual dosage of ingredients that consumers are exposed to through precise exposure assessment.

Risk characterization: Compare the toxicological data of raw materials with consumer exposure levels to evaluate the overall safety of cosmetics. If the exposure level of a certain ingredient exceeds its safety threshold, further risk analysis is required and corresponding control measures need to be proposed, such as adjusting the formula, reducing ingredient content, or replacing raw materials.

Applicable products

Skin care products: skin care products such as facial cleanser, toner, lotion, face cream, facial mask, etc., which are in direct contact with the skin, require TRA certification test to ensure that the products will not cause harm to the skin and protect the skin health of consumers.

Cosmetic products: lipstick, eye shadow, powder blusher, liquid foundation and other cosmetics products will not only contact the skin, but also may enter the human body due to ingestion. Through TRA certification testing, the safety of ingredients in products can be evaluated to avoid potential risks to consumers' health.

Care products: shampoo, conditioner, shower gel, and other care products that come into prolonged contact with the skin and hair during use. TRA certification testing ensures the safety of these products and provides consumers with a reassuring user experience.
