AInsights Entry for PEG-20 Glyceryl Ricinoleate (CAS: 51142-51-9)

1. Identity & Chemical Information

Common Name(s): PEG-20 Glyceryl Ricinoleate
IUPAC Name: Poly(oxy-1,2-ethanediyl), α-(1-oxo-9-octadecenyl)-ω-hydroxy-, (Z)-
CAS Number: 51142-51-9
FEMA Number: Not applicable
Other Identifiers: Not applicable
Molecular Formula: C21H40O4(C2H4O)n
Molecular Weight: Variable due to polymeric nature
Functional Groups and Structure–Odor Relevance: PEG-20 Glyceryl Ricinoleate is an ester of ricinoleic acid and polyethylene glycol. The presence of the ricinoleate moiety contributes to its emollient properties, while the PEG component enhances solubility in water, making it useful in formulations requiring emulsification.

2. Sensory Profile

PEG-20 Glyceryl Ricinoleate is primarily used for its functional properties rather than its sensory attributes. It does not have a significant odor or flavor profile, which makes it suitable for applications where neutral sensory impact is desired. Its role is more about modifying texture and stability rather than contributing to the sensory characteristics of a product.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

PEG-20 Glyceryl Ricinoleate is a synthetic compound and does not occur naturally. It is produced through the esterification of ricinoleic acid, derived from castor oil, with polyethylene glycol. This process does not involve natural pathways such as fermentation or enzymatic degradation, and thus it is not classified under "natural flavor" or "natural fragrance" designations.

4. Use in Flavors

PEG-20 Glyceryl Ricinoleate is not typically used for its flavor properties but rather as an emulsifier in flavor systems. It helps in stabilizing emulsions, ensuring uniform distribution of flavor compounds in aqueous systems. Typical use levels in food and beverage formulations are not well-documented, but industry practices suggest usage in the range of 100-1000 ppm, depending on the specific application and regulatory guidelines.

5. Use in Fragrances

In fragrance applications, PEG-20 Glyceryl Ricinoleate serves as a solubilizer and emulsifier, facilitating the incorporation of fragrance oils into aqueous systems. It is used across various fragrance families and product types, including lotions, creams, and sprays. Concentration levels vary widely, typically ranging from 0.1% to 5% depending on the formulation requirements. Its volatility is low, contributing primarily to the base note stability.

6. Regulatory Status (Regional Overview)

United States: Not specifically listed as GRAS by FEMA; used under general safety guidelines for emulsifiers.
European Union: Not explicitly listed under Regulation (EC) No 1334/2008; used in compliance with general food additive regulations.
United Kingdom: Follows EU guidelines post-Brexit with no significant divergence reported.
Asia: Usage is subject to national regulations; generally accepted as a food additive in Japan and China.
Latin America: Usage aligns with MERCOSUR regulations, with specific approvals varying by country.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Generally recognized as safe when used as an emulsifier in food products. No specific ADI or MSDI established.
Dermal Exposure: Considered non-irritating and non-sensitizing at typical use levels in cosmetic formulations. IFRA does not list specific restrictions.
Inhalation Exposure: Low volatility minimizes inhalation risks; occupational exposure considerations are minimal.

Overall, the risk profile does not significantly differ between food and fragrance applications, with safety largely supported by its long history of use and low toxicity.

8. Practical Insights for Formulators

PEG-20 Glyceryl Ricinoleate is valued for its emulsifying properties, enhancing the stability and texture of formulations. It synergizes well with other emulsifiers and stabilizers, providing flexibility in product development. Common pitfalls include overuse leading to undesirable texture or underuse resulting in phase separation. It is frequently under-utilized in formulations requiring mild emulsification.

9. Confidence & Data Quality Notes

Data on PEG-20 Glyceryl Ricinoleate is well-established in terms of its functional properties and safety profile. However, specific sensory data and detailed regulatory approvals are less documented, relying on industry-typical practices and general safety guidelines.

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.
