Fragrance compliance in cosmetics requires alignment with two interconnected frameworks. One consists of legally binding government regulations, such as the EU Cosmetic Regulation. The other involves self-regulatory standards established by the fragrance industry. Together, these frameworks aim to protect consumer health while allowing manufacturers to create appealing and effective fragranced products.

The primary objective of fragrance compliance is to reduce the risk of allergic reactions and skin sensitization without compromising product performance or consumer experience.

IFRA Standards and Industry Self-Regulation

The International Fragrance Association (IFRA) Standards form the foundation of fragrance compliance worldwide. Although these standards are not legal requirements, cosmetic manufacturers widely adopt them as the accepted benchmark for fragrance safety.

The Research Institute for Fragrance Materials (RIFM) provides the scientific basis for IFRA Standards through toxicological research and risk assessment. IFRA updates its standards regularly to reflect new scientific findings and exposure data.

IFRA Standards classify fragrance ingredients into three main categories. Prohibited substances are not allowed for use due to health or environmental concerns. Restricted substances may be used only within defined maximum concentration limits. Specification standards apply to ingredients that must meet strict purity or compositional requirements.

To account for different exposure scenarios, IFRA assigns products to specific categories based on application area and usage pattern. For example, lip products and body lotions fall under different categories with different permissible use levels. These categories determine the maximum allowed concentration of restricted fragrance ingredients in the finished product.

Fragrance suppliers must issue an IFRA Certificate of Conformity for each fragrance compound. This certificate confirms compliance with the latest IFRA Standards for the intended cosmetic product category and forms a key part of cosmetic safety documentation.

Allergen Labelling Requirements Under Cosmetic Law

While IFRA Standards focus on formulation safety, cosmetic regulations emphasize transparency through allergen labelling. In the European Union, Regulation (EC) No 1223/2009 establishes clear requirements for the disclosure of fragrance allergens.

Manufacturers may generally declare fragrance compositions using the terms “Parfum” or “Aroma” to protect proprietary formulations. However, this allowance does not apply to substances known to cause contact sensitization.

When specific fragrance allergens exceed defined concentration thresholds, manufacturers must list them individually in the ingredient declaration. The threshold is 0.001 percent for leave-on products such as creams and perfumes. For rinse-off products, including shampoos and shower gels, the threshold is 0.01 percent.

Based on scientific advice from the Scientific Committee on Consumer Safety (SCCS), the European Union has expanded the list of mandatory fragrance allergens. Recent amendments, including Regulation (EU) 2023/1545, increased the number of substances requiring individual labelling to more than 80. This change obliges many brands to reformulate products and update packaging to remain compliant.

Integrating IFRA Compliance and Allergen Labelling

Effective fragrance compliance combines two distinct but complementary obligations. IFRA Standards determine which fragrance ingredients may be used and at what concentration levels. Allergen labelling requirements define which substances must appear on the product label.

By integrating both frameworks into product development and regulatory review processes, cosmetic manufacturers can ensure fragrance safety, regulatory compliance, and clear consumer communication across all markets.
