FlavScents AInsights Entry for Castoryl Maleate (CAS: 241153-84-4)

1. Identity & Chemical Information

Common Name(s): Castoryl Maleate
IUPAC Name: Hexadecanoic acid, 12-hydroxy-, 2-[(2Z)-but-2-enedioate]
CAS Number: 241153-84-4
FEMA Number: Not applicable
Other Identifiers: Not available
Molecular Formula: C22H38O5
Molecular Weight: 382.54 g/mol
Functional Groups and Structure-Odor Relevance: Castoryl maleate is an ester derived from castor oil and maleic acid. The presence of hydroxyl and ester groups contributes to its emollient properties, which are relevant in fragrance applications for their skin-feel characteristics rather than direct odor impact.

2. Sensory Profile

Odor and Flavor Descriptors: Castoryl maleate itself is not primarily used for its odor or flavor but rather for its functional properties in formulations. It may impart a subtle, waxy, and slightly fatty note.
Taste and/or Odor Thresholds: Data not found.
Typical Sensory Role: It serves as a modifier in fragrance formulations, providing a smooth, emollient base that enhances the longevity and diffusion of other fragrance components.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: Castoryl maleate is a synthetic compound derived from natural castor oil and maleic acid.
Formation Pathways: It is produced through the esterification of ricinoleic acid (from castor oil) with maleic anhydride.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: While derived from natural sources, the chemical modification involved in its synthesis typically precludes it from being labeled as "natural" under most regulatory definitions.

4. Use in Flavors

Flavor Categories and Applications: Not commonly used in flavor applications due to its primary role as a fragrance ingredient.
Functional Role in Flavor Systems: Data not found.
Typical Use Levels: Data not found.
Stability Considerations: Castoryl maleate is stable under typical storage conditions but may hydrolyze under extreme pH conditions or prolonged exposure to heat.

5. Use in Fragrances

Fragrance Families and Product Types: Used in a variety of personal care products, including lotions, creams, and perfumes.
Functional Role: Acts as an emollient and fixative, enhancing the texture and longevity of fragrance compositions.
Typical Concentration Ranges: Typically used at concentrations ranging from 0.1% to 5% in finished products.
Volatility and Top/Middle/Base Contribution: Contributes to the base note, providing a long-lasting, smooth background.

6. Regulatory Status (Regional Overview)

United States (FDA / FEMA GRAS): Not listed as GRAS for flavor use; primarily regulated as a cosmetic ingredient.
European Union (Reg. (EC) No 1334/2008; FL number status): Not listed for flavor use; regulated under cosmetic directives.
United Kingdom: Follows EU regulations post-Brexit.
Asia (Japan, China, ASEAN): Primarily regulated as a cosmetic ingredient; specific flavor use regulations not found.
Latin America (e.g., Brazil, MERCOSUR): Regulated under cosmetic guidelines; specific flavor use regulations not found.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Not typically relevant due to its primary use in non-food applications.
Dermal Exposure: Generally considered safe for use in cosmetics; low potential for irritation or sensitization.
Inhalation Exposure: Low volatility reduces inhalation risk; primarily a concern in occupational settings during manufacturing.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Why This Material is Valuable: Provides emollient properties and enhances the longevity of fragrances.
Typical Synergies: Works well with other esters and alcohols to create smooth, long-lasting fragrance bases.
Common Formulation Pitfalls: Overuse can lead to greasy textures in cosmetic formulations.
Situations Where It is Frequently Over- or Under-Used: Often under-utilized in formulations seeking to enhance skin feel and fragrance longevity.

9. Confidence & Data Quality Notes

Well-Established Data: Regulatory status and safety profile as a cosmetic ingredient.
Industry-Typical but Undocumented Practices: Use levels and functional roles in fragrance formulations.
Known Data Gaps or Regulatory Ambiguities: Limited data on flavor use and specific regulatory approvals for such applications.

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.
