Rose Water, Distillation and Scientific Research

Rose water is one of the most valued botanical products used for centuries in personal care, cosmetics and everyday life. However, not every product described as “rose water” is made using the same production method or has the same composition.

The nature and quality of the final product are determined by more than the species of rose used. The time of harvest, the distillation method, the duration and pressure of the process, whether the naturally occurring rose oil is separated, and how the finished product is preserved are all important factors.

In this section of Akita Rose Academy, we will follow the journey of Rosa damascena flowers from harvest through distillation. We will explain how rose oil is produced, what products can be obtained after distillation, and the fundamental differences between traditional rose water and non-de-oiled rose distillate.

One important question will guide this section:

What happens when the natural rose oil formed during distillation is not separated and is instead preserved within the rose distillate?

In traditional rose oil production, the oil phase is separated as the principal and most valuable product. The remaining aromatic water phase is then evaluated and may be bottled as rose water.

The non-de-oiled approach begins with a different production objective. Its primary purpose is not to extract rose oil as a separate product. Instead, the duration, pressure and other conditions of distillation are specifically adjusted to produce the rose distillate itself as the principal product.

This approach aims to preserve a broader spectrum of distillation-carried components, including water-soluble aromatic compounds and compounds associated with the natural oil phase—within a single, more complete distillate.

This distinction does not mean that traditional rose water is unreal or without value. Both products can be obtained through the distillation of Rosa damascena flowers. The essential differences concern the purpose of production, the distillation conditions, whether the rose oil is separated, and the resulting composition of the final product.

This section also explains what the INCI name Rosa Damascena Flower Distillate means and why it is used on cosmetic ingredient labels. By considering production knowledge, chemical analyses and scientific research together, we will also clarify some common misconceptions about rose water.

The purpose of Akita Rose Academy is to explain the differences between production methods in a clear, objective and scientifically responsible way, without diminishing the value of traditional practices. To understand and evaluate a rose water product accurately, it is important to consider not only the wording on the front label, but also the rose species, INCI name, production method and available analytical results.

What Will You Learn in This Section?

1. What Is Real Rose Water?

Explore the historical and technical meanings of rose water, how authentic rose water is produced, and why products with different compositions may be sold under the same general name.

2. How Is Rose Water Produced?

Follow the complete production process, from harvesting Rosa damascena flowers and transporting them to the distillation facility to condensing the steam-carried components and obtaining the finished distillate.

3. Differences Between Traditional Rose Water and Non-De-Oiled Rose Distillate

Compare the two products according to their production purpose, distillation conditions, separation or preservation of the natural rose oil, and resulting component profiles.

The Rose Distillation Series

Part 1 — The Distillation Journey of a Rose

Learn why roses are traditionally harvested early in the morning, why the time between harvesting and processing matters, and how the flowers are prepared for distillation.

Part 2 — How Does Rose Distillation Work?

Discover the fundamental principles of rose distillation and how water, steam, temperature, pressure and process duration may influence the final product.

Part 3 — How Is Rose Oil Produced?

Learn how the volatile oil of Rosa damascena is obtained through distillation and how the natural oil phase is separated from the condensed distillate.

Part 4 — What Is Obtained After Distillation?

Explore the terms used for products that may be obtained after distillation, including rose oil, the aromatic water phase, traditional rose water and rose distillate.

Part 5 — How Is Non-De-Oiled Rose Distillate Produced?

Discover the production approach in which rose oil is not removed as a separate product and the distillate itself is created as the principal product.

Part 6 — What Happens When Rose Oil Is Not Separated During Distillation?

Examine how preserving the components associated with the natural rose oil phase within the distillate may influence its chemical composition, aroma and sensory character.

Part 7 — What Does the INCI Name “Rosa Damascena Flower Distillate” Mean?

Learn what this INCI name identifies on cosmetic labels and how the terms “flower water” and “flower distillate” should be understood and evaluated.

A More Informed Way to Understand Rose Water

Rose water should not be evaluated by fragrance alone. Its botanical origin, production purpose, distillation conditions, natural component profile and analytical findings all contribute to its identity.

Through this educational series, Akita Rose Academy invites readers to look beyond the familiar name “rose water” and discover the science, craftsmanship and production decisions behind every distillate.
