Ever wondered what makes your favorite skincare products so effective? Dive into the world of ROSE KETONE-5 and discover its transformative power in cosmetics, from its creation to its myriad benefits and essential considerations.

What is Rose Ketone-5?

Rose Ketone-5, also known by its chemical name 1-(2,4,4-Trimethyl-2-cyclohexenyl)-2-buten-1-one, is a synthetic fragrance ingredient used primarily in the cosmetic industry. This compound is part of a family of ketones that are known for their pleasant, floral aroma, which makes them highly desirable in the formulation of perfumes and scented products.

The history of Rose Ketone-5 in cosmetics dates back to the mid-20th century when chemists began to explore synthetic alternatives to natural rose oil, which was expensive and labor-intensive to produce. By isolating and synthesizing specific aromatic compounds, scientists were able to create cost-effective and consistent fragrance ingredients. Rose Ketone-5 emerged as one of these synthetic alternatives, offering a stable and long-lasting scent profile that mimics the natural aroma of roses.

The production of Rose Ketone-5 involves a series of chemical reactions starting from basic organic compounds. Typically, the process includes the cyclization of a precursor molecule to form the cyclohexenyl ring, followed by the introduction of the butenone side chain. This synthesis is carried out in controlled laboratory conditions to ensure the purity and consistency of the final product. The result is a versatile fragrance ingredient that can be used in a variety of cosmetic formulations, from perfumes to lotions and creams.

The Benefits/Uses of Rose Ketone-5

In this section, we will delve into the officially recognized cosmetic benefits and uses of Rose Ketone-5:


Rose Ketone-5 is primarily used for its perfuming properties. This means that it is added to cosmetic products to impart a pleasant fragrance. The ingredient is known for its ability to provide a fresh, floral scent reminiscent of roses, which can enhance the sensory experience of using a product. Whether it’s in a lotion, cream, or perfume, the inclusion of Rose Ketone-5 can make the product more appealing by adding a delightful aroma.

Note: The listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).

Potential Side Effects & Other Considerations

Rose Ketone-5, while primarily used for its perfuming properties in cosmetic products, is generally considered safe for topical application. However, as with any ingredient, there are potential side effects and considerations to keep in mind.

  • Skin irritation
  • Allergic reactions
  • Contact dermatitis

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Rose Ketone-5 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.

Adverse reactions to Rose Ketone-5 are relatively uncommon, but they can occur, especially in individuals with sensitive skin or allergies. To minimize the risk of adverse reactions, it is recommended to perform a patch test before widespread usage.

In terms of comedogenicity, Rose Ketone-5 has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that it is unlikely to clog pores, making it generally suitable for people prone to acne, blemishes, or breakouts.
