FlavScents AInsights Entry for Quillaja Saponaria Bark Extract (CAS: 68990-67-0)

1. Identity & Chemical Information

Quillaja saponaria bark extract, commonly referred to as Quillaja extract, is a natural complex material derived from the bark of the Quillaja saponaria tree, native to South America. It is not a single compound but a mixture primarily composed of saponins, which are glycoside compounds known for their surfactant properties. The CAS number for this extract is 68990-67-0. It does not have a specific FEMA number due to its complex nature. The extract is often used in both flavor and fragrance applications due to its foaming and emulsifying properties.

2. Sensory Profile

Quillaja saponaria bark extract is not typically used for its odor or flavor characteristics but rather for its functional properties. However, it can impart a mild, earthy, and slightly bitter taste when used in higher concentrations. Its primary sensory role is as a modifier, enhancing the texture and stability of flavor systems rather than contributing a distinct aroma or taste.

3. Natural Occurrence & Formation

Quillaja saponaria is naturally found in the forests of Chile and Peru. The extract is obtained through aqueous extraction of the bark, which is rich in saponins. These compounds are naturally occurring glycosides that form as part of the plant's defense mechanism. The extract is considered a natural flavoring agent, aligning with "natural flavor" designations due to its direct derivation from plant material.

4. Use in Flavors

Quillaja extract is primarily used in flavor applications for its emulsifying and foaming properties, rather than its flavor profile. It is commonly found in beverages, particularly in soft drinks and alcoholic beverages, where it helps stabilize emulsions and create a foamy head. Typical use levels range from 50 to 500 ppm in finished products, with specific concentrations depending on the desired effect and product type. It is stable under a wide range of pH conditions but may degrade under high heat.

5. Use in Fragrances

In fragrance applications, Quillaja extract is valued for its ability to enhance the solubility and stability of fragrance compounds in aqueous systems. It is used in a variety of product types, including shampoos, body washes, and other personal care products. The extract contributes to the middle note of fragrances, providing a subtle earthy background. Typical concentrations are qualitative, as its primary role is functional rather than olfactory.

5a. Key Constituents (Typical)

The key constituents of Quillaja saponaria bark extract include saponins, which are the primary active components. These saponins can vary significantly in composition depending on the origin, harvest time, and processing methods. Other minor constituents may include polyphenols and tannins, contributing to its functional properties.

6. Regulatory Status (Regional Overview)

In the United States, Quillaja extract is generally recognized as safe (GRAS) for use in food and beverages. In the European Union, it is approved under Regulation (EC) No 1334/2008 as a flavoring substance. The UK follows similar regulations post-Brexit. In Asia, its use is permitted in Japan and China, although specific regulations may vary. In Latin America, countries like Brazil recognize its use in food products, aligning with international standards.

7. Toxicology, Safety & Exposure Considerations

Quillaja extract is considered safe for oral consumption at typical use levels, with an acceptable daily intake (ADI) established by regulatory authorities. Dermal exposure in fragrance applications is generally safe, although high concentrations may cause irritation. Inhalation exposure is minimal due to its low volatility. The risk profiles for food and fragrance applications are similar, with no significant differences noted.

8. Practical Insights for Formulators

Quillaja extract is valued for its multifunctional role in formulations, providing both emulsification and foaming properties. It synergizes well with other natural emulsifiers and stabilizers. Formulators should be cautious of its potential to impart bitterness at high concentrations and ensure compatibility with other ingredients to avoid precipitation or separation.

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.
