Generally recognized as safe (GRAS)

Generally recognized as safe (GRAS) is a designation from the U.S. Food and Drug Administration (FDA) indicating that a substance added to food is considered safe by qualified experts, as having been adequately shown to be safe under the conditions of its intended use. Safety is determined through scientific procedures (sections 201(s) and 409) or experience based on common use for substances used in food prior to 1958 (21 CFR 170.30(b)) with substantial history of consumption for food by a significant number of people.

Certified Organic

A labeling term that indicates a food or product has been produced according to a certifying body’s approved methods. Requirements vary from country to country and by certifying body, but generally involve a set of production standards for growing, storage, processing, packaging, and shipping that include: avoidance of genetically modified seeds, avoidance of chemical fertilizers, pesticides, food additives, and antibiotics, avoidance of irradiation, use of farmland that has been free from prohibited chemicals for a number of years (often three or more), maintaining auditable records, and periodic on-site inspections.

National Sanitation Foundation (NSF)

NSF International is a respected and recognized third-party certifier of dietary supplements that ensures retailers comply with strict standards and procedures. NSF certification signifies that the product has been tested and met or exceeded standards for purity and quality and contains what is listed on the label and nothing else. NSF certification requires regular inspection and re-testing of products.

Paraben Free

Parabens—such as methylparaben, propylparaben, butylparaben, and ethylparaben—are chemical preservatives used in a majority of cosmetic and personal care products. Companies use parabens in their formulations to preserve the shelf-life of their products. Parabens can cause a myriad of adverse health effects such as endocrine disruption. Allergic reactions are commonly experienced with paraben-filled products. Our paraben free products don’t include any of these petrochemicals in their formulas.

Sulfate Free

Sulfates are commonly found in many personal care products such as shampoo, face cleanser, and body wash. Used as a detergent, sulfates—such as Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES)—are powerful detergents. However, sulfates aggressively remove grease from hair, skin, and other surfaces, often leaving them without their naturally-occurring, protective oils. Sulfates are easily absorbed into the skin and can remain in tissues for extensive periods of time. Our sulfate free products are free from sulfates and the negative health effects that can come from using them.
