Syensqo (formerly Solvay) is a leading global provider of innovative solutions for various industries, including the food and beverage industry. With a focus on scientific research and technology, Syensqo develops high-quality ingredients that enhance the taste, texture and overall experience of food products. Their expertise spans multiple sectors, with the provision of premium flavor enhancers, such as vanillin and ethyl vanillin, putting them at the forefront of food innovation.
Gillco's Partnership with Syensqo
Our collaboration with Syensqo began in 2023 and enabled Gillco to distribute Syensqo's innovative flavor-enhancing ingredients to food manufacturers in the United States. Our focus is on high purity vanillin and ethyl vanillin products. These ingredients play a critical role in enhancing the flavor profiles of various food applications, including baked goods, beverages, chocolate, dairy products and snacks.
Syensqo’s Flavor Enhancement Offerings
Gillco Ingredients distributes two key flavor-enhancing ingredients from Syensqo’s portfolio: vanillin and ethyl-vanillin. Both products are renowned for their high purity, consistent quality, and ability to elevate the taste profiles of a wide range of food products.
Vanillin
Vanillin is the main aroma compound found in vanilla bean extract, responsible for the typical sweet, creamy vanilla flavor that is beloved in food products worldwide. Syensqo’s vanillin, branded under the name Rhovanil®, is known for its purity and consistency, making it the industry standard for vanillin used in food applications.
-Composition: Rhovanil® vanillin is a white to slightly off-white crystalline powder with a rich vanilla flavor note.
-Purity: With a purity level of 99.95%, Rhovanil® stands out in the market for its consistent flavor quality. Most other vanillin products on the market offer 99.5% purity, which can result in variable flavor properties.
-Functionality: Rhovanil® adds a pure, sweet, creamy vanilla note to food applications, making it a cost-effective substitute for natural vanilla.
Applications of Rhovanil® Vanillin:
Ethyl-Vanillin
Ethyl-vanillin, sold under the Rhodiarome® brand, is another essential flavor compound offered by Syensqo. Although it does not naturally occur in vanilla beans, ethyl-vanillin is widely used in the food industry due to its stronger flavor profile compared to vanillin.
-Composition: Ethyl-vanillin is a white to slightly off-white crystalline powder, similar in appearance to vanillin but with a flavor strength that is up to three times stronger.
-Purity: Like Rhovanil®, Rhodiarome® ethyl-vanillin offers a purity level of 99.95%, ensuring flavor consistency in all food applications.
-Functionality: Rhodiarome® provides a warm, rich vanilla note, making it a cost-effective alternative to natural vanilla, especially in products where a stronger vanilla flavor is desired.
Applications of Rhodiarome® Ethyl-Vanillin:
-Bakery
-Beverages
-Desserts
-Frozen Foods
-Snacks
Rhodiarome® ethyl-vanillin is ideal for food products that require a more intense vanilla flavor. Its strength allows manufacturers to use smaller quantities, making it a more economical choice for large-scale production.

Syensqo’s Rhovanil® vanillin and Rhodiarome® ethyl-vanillin are the go-to flavor solutions for food manufacturers around the globe. Here are some of the key reasons why these products are trusted by the industry:
