Scientific Facts

Plant derived (botanical) ingredients were among the very first cosmetics. Natural colorants, plant juices for soothing and protection from insect pests, and fragrant oils for imparting odor were all known and used in ancient times. Using plants as a source of cosmetic ingredients was the only way to produce products for cleaning, moisturizing, covering up blemishes and even treating minor skin conditions before our knowledge of science allowed the creation of new materials to improve on what nature offers. Rosemary (Rosmarinus officinalis) is a woody, perennial herb with fragrant evergreen needle-like leaves. The fresh and dried leaves are used often in Mediterranean cuisine.

Safety Information

The Food and Drug Administration (FDA) includes Rosemary (Rosmarinus officinalis) on its list of spices and other natural seasonings and flavorings considered Generally Recognized As Safe (GRAS). Botanical and botanically-derived ingredients used in the formulation of cosmetics are generally mild and safe. Prior to marketing the finished cosmetic product, the safety of each ingredient must be substantiated in accordance with 21 CFR 740.10. Safety substantiation of cosmetic ingredients may include tests for ocular and skin irritation as well as allergenicity, phototoxicity, photoallergenicity and mutagenicity, depending on the application or intended use. There is a considerable body of information about the safety of botanical ingredients and a well established history of use. These resources are consulted to ensure the safety of these materials as they are used in cosmetics and personal care products.

In selecting botanical ingredients for preparation of cosmetic products, formulators rely on the extensive history of their preparation and use. Such materials have been used for a long time and, based upon this experience, extensive knowledge of their safety has been gained. In the situation of newly identified botanicals in the cosmetic industry, appropriate ocular and skin safety studies are conducted prior to release into general commerce. There are many different references that describe the isolation, use and safety of botanical preparations.

More Scientific Information

A botanical ingredient is a plant or plant part obtained from natural plant sources. Botanical ingredients are among the oldest materials used in the preparation of cosmetics and are valued for their properties, such as color, flavor, and/or scent. Botanical ingredients can be prepared from all or some of the parts of the plant. They may also be obtained using extracting solvents (such as alcohol), infusion with water, steam treatment to obtain essential oils or simply by drying and grinding the material. It is important to follow good manufacturing practices (GMP) to make sure the ingredient composition is consistent from one batch to another and to make sure that the ingredient does not degrade or grow microorganisms. In naming plants, botanists use a Latin name made up of the genus and species of the plant. For example, under this system the plant, Rosemary is known as Rosmarinus officinalis L., where “L” stands for Linneaus, who first described the type of plant specimen. Plants are also known by a common name that has been handed down through generations. These common names may vary from country to country. Therefore, Latin names, which are more likely to be recognized in many countries, are frequently used on the label of a product to identify an ingredient made from plants.
