Why Your Favorite Perfume Smells Different: The Mystery of Reformulation

Impacts of EU Regulations on Fragrance Creation

The European Union's decision to limit the use of oakmoss in perfumes raised significant concerns within the fragrance industry. Ramón Monegal, a notable perfumer, emphasized the ingredient's importance for creating chypres and fougères, two essential fragrance families. Oakmoss is valued for its warm, earthy, and woody qualities, but it also poses potential health risks, such as dermatitis. In response to these concerns, regulators instituted strict usage limits, ultimately affecting the creative processes of perfumers.

Regulatory Framework and Safety Standards

To address consumer safety and environmental impacts, organizations like the International Fragrance Association (IFRA) have established guidelines that dictate the responsible use of fragrance ingredients. These ingredients undergo thorough toxicological and dermatological testing; if concerns arise, their usage is either restricted or banned. Importantly, these regulations affect not only new products but also existing fragrances, demanding that perfume houses reformulate their offerings while maintaining the integrity of the original scent.

IFRA updates its standards regularly, approximately every two to three years. According to Belén Carazo, scientific and technical director of Spain‘s National Association of Perfumery and Cosmetics (Stanpa), the current standard is IFRA Guide 50, with the next iteration already in development. Additionally, the EU revises its Cosmetics Regulation through Omnibus Regulations, which introduce new restrictions based on emerging scientific research.

Challenges in Reformulating Fragrances

Reformulating fragrances to meet new compliance requirements is a labor-intensive aspect of a perfumer's job, often operating behind the scenes. Traditionally a manual process, innovation has introduced technology that streamlines these adaptations, including advanced spreadsheets and artificial intelligence.

For example, oakmoss has frequently been replaced with a synthetic alternative called Evernyl. However, it isn't the sole ingredient under scrutiny. The company PyD undertook two significant reformulations of its classic Halloween Eau de Toilette, first in 2018 and again in 2021. Anaïs Paillard, fragrance development coordinator at PyD, detailed the process of achieving a similar scent profile while substituting certain molecular components with fresh floral notes to maintain the original fragrance experience.

Finding Alternatives and Balancing Scents

When a key ingredient is restricted, perfumers often experiment to find effective replacements. Monegal, representing four generations of expertise in the family-owned Myrurgia, described his method: removing the problematic ingredient from the composition and assessing the resultant fragrance. If the outcome falls short, he employs a variety of substitutes or blends until balance is achieved.

Notably, the distinction between natural and synthetic ingredients influences these decisions. While natural materials can vary based on environmental factors, synthetic alternatives offer consistency. Monegal explained that customer preference may not discern the subtle differences between natural and synthetic ingredients since most consumers lack trained olfactory senses. Additionally, fragrance variations can arise yearly due to changes in natural ingredient availability and quality.

Discontinuing Fragrances and Introducing Flankers

In cases where reformulation is not viable, perfume houses may opt to discontinue a fragrance entirely or introduce flankers—new interpretations of existing scents designed to comply with updated regulations. Monegal noted that some original formulas may eventually phase out as these updated versions gain acceptance in the market.

Natural vs. Synthetic: Safety and Cost Implications

The current trend toward natural products coincides with heightened scrutiny over potentially harmful ingredients. Carazo acknowledged the perception that natural substances are inherently safer; however, she noted that natural compounds can also contain allergens requiring strict regulation. In contrast, synthetic molecules often allow for better control over both safety and cost—an essential factor for the perfume industry.

Despite the advancements afforded by synthetic chemistry, Monegal warned of the unique qualities lost in the purely synthetic approach. Nonetheless, industry experts agree that the challenge lies in crafting exclusively beautiful products while adapting to ever-evolving safety regulations. Monegal concluded that such restrictions have ultimately spurred creativity and innovation within the industry.
