AInsights Entry for Cascalone (Firmenich) (CAS: 950919-28-5)

1. Identity & Chemical Information

Cascalone, a proprietary fragrance ingredient developed by Firmenich, is known for its unique aquatic and fresh scent profile. The IUPAC name for Cascalone is not publicly disclosed due to its proprietary nature. The CAS number for Cascalone is 950919-28-5. It does not have a FEMA number as it is primarily used in fragrance applications rather than flavors. The molecular formula and molecular weight are also proprietary. Cascalone is characterized by its functional groups that contribute to its fresh, watery scent, making it a popular choice in aquatic-themed fragrances.

2. Sensory Profile

Cascalone is renowned for its fresh, aquatic, and ozonic odor profile. It is often described as having a clean, watery scent with subtle floral undertones. The intensity of Cascalone is moderate, providing a refreshing and uplifting character to fragrance compositions. It is typically used as an impact note in fragrance formulations, contributing to the overall freshness and clarity of the scent. Specific odor thresholds are not publicly available, but it is known for its ability to impart a long-lasting freshness.

3. Natural Occurrence & Formation

Cascalone is a synthetic compound and does not occur naturally. It is created through proprietary synthetic pathways developed by Firmenich. As a synthetic ingredient, it does not qualify for "natural flavor" or "natural fragrance" designations. Its creation involves advanced organic synthesis techniques to achieve its distinctive aquatic scent profile.

5. Use in Fragrances

Cascalone is widely used in the fragrance industry, particularly in the creation of aquatic, fresh, and ozonic fragrance families. It serves as a key impact note, providing a fresh and clean character to perfumes, body sprays, and personal care products. Typical concentration ranges in fragrance formulations vary, but it is often used at levels that ensure a noticeable yet balanced presence. Cascalone contributes primarily to the top and middle notes of a fragrance, offering moderate volatility and a long-lasting fresh effect.

6. Regulatory Status (Regional Overview)

In the United States, Cascalone is regulated under the guidelines for fragrance ingredients, with no specific restrictions noted. In the European Union, it is subject to the general safety assessments for fragrance compounds under Regulation (EC) No 1334/2008. The United Kingdom follows similar regulatory frameworks post-Brexit. In Asia, including Japan and China, Cascalone is used in compliance with local fragrance regulations. In Latin America, countries like Brazil and members of MERCOSUR also adhere to international safety standards for fragrance ingredients.

7. Toxicology, Safety & Exposure Considerations

Cascalone's safety profile is primarily evaluated for dermal exposure, as it is used in topical fragrance applications. It is generally considered non-irritating and non-sensitizing at typical use levels in personal care products. Inhalation exposure is also considered safe under normal use conditions, with no significant occupational hazards reported. Oral exposure is not relevant due to its non-use in flavors. Overall, Cascalone is deemed safe for use in fragrances, with a favorable safety margin.

8. Practical Insights for Formulators

Cascalone is valued for its ability to impart a fresh, aquatic character to fragrance compositions. It synergizes well with other ozonic and floral notes, enhancing the overall freshness and appeal of the fragrance. Formulators should be mindful of its moderate intensity to avoid overpowering other scent components. It is often under-used in formulations seeking a subtle aquatic touch, while overuse can lead to an overly synthetic impression.

9. Confidence & Data Quality Notes

The data on Cascalone is well-established within the fragrance industry, supported by Firmenich's proprietary research and development. While specific numeric values for sensory thresholds and molecular details are proprietary, industry practices and safety assessments provide a reliable framework for its use. Known data gaps include the lack of publicly available detailed toxicological studies, which are typically proprietary.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
