Food Grade vs Cosmetic Grade vs Pharmaceutical Grade
What food grade, cosmetic grade and pharmaceutical grade mean in the US sources we read, why the law sorts products by intended use, and why a grade is not a safety label.

Safety first. Supplements can cause side effects and interact with medicines. Read mushroom safety and interactions before you use any mushroom product.
Quick answer: "food grade," "cosmetic grade" and "pharmaceutical grade" are sales words, not three official quality levels you can rank. In the US sources we read, the law sorts a product by its intended use (food, cosmetic, drug or supplement), and each group has its own rules. A grade on a label does not tell you a product is safe to swallow, put on skin or use for a health problem.
Urgent: do not swallow a product that is not sold for eating. If someone has, call Poison Help at 1-800-222-1222 (US). Call 911 for collapse, seizure, trouble breathing, or swelling of the face or throat.
How the sources use each term
| Term | Where we found it | What it says | What it does not tell you |
|---|---|---|---|
| Food grade | Federal rules for substances "generally recognized as safe" (GRAS) in food | The rules define good manufacturing practice for GRAS substances to include being of appropriate food grade and being prepared and handled as a food ingredient. [1][2] The regulation adds that, on request, the Commissioner will offer an opinion on whether a particular grade or lot is of suitable purity for use in food. [1] | These sections describe conditions for specific food ingredients. The text we read does not say what a seller's "food grade" label on a retail product means. |
| Cosmetic grade | Proper evidence not found | We read the FDA pages on cosmetic claims, organic cosmetics, hypoallergenic cosmetics, cosmetic-or-drug status and FDA's authority over cosmetics, and none defines "cosmetic grade." | Whether the ingredient meets any particular purity standard. |
| Pharmaceutical grade | Proper evidence not found as a defined term | The FDA's compounding page says pharmacists and physicians compounding under section 503A may only use bulk drug substances that comply with an applicable USP or NF monograph if one exists. [3] Such substances must come with a valid certificate of analysis. [3] | That page is about compounded medicines, not shop-bought natural products. We could not read the USP site (access was blocked), so we cannot describe USP's own definitions. |
A grade is not a "where it is safe" label
The same plant material can be safe in one setting and harmful in another. The FDA gives the example that cumin oil is safe in food but can cause the skin to blister. [8] And the FDA states that all cosmetic products and ingredients must meet the same safety requirement regardless of their source. [8]
Some substances sold with "food grade" in the name, such as diatomaceous earth, are covered on their own pages because the grade word is often misunderstood: see Diatomaceous earth claims checked and Natural substances not meant to be swallowed.
What to look at instead
- Intended use on the package: is it sold as a food, a supplement, a cosmetic or a medicine? Treat a "do not ingest" or "for external use" statement as a limit.
- The full ingredient list and the manufacturer's contact details. See How to read an ingredient label.
- Independent testing, and what it covers. See Quality testing and certifications and Natural Ingredient Quality and Labels.
- Medicines and health conditions: ask a pharmacist or clinician first. See how interactions work.
What we could not verify
We did not find an official US definition of "cosmetic grade," or of "pharmaceutical grade" for consumer products. The USP and NIH Office of Dietary Supplements pages we tried were blocked to us (HTTP 403), so nothing here relies on them. We also did not search regulators outside the US.
Frequently asked questions
Is food grade safer than cosmetic grade?
The sources we read do not rank them. They treat food, cosmetics, drugs and supplements as different categories with different rules. [4][1]
Can I swallow something labeled "pharmaceutical grade"?
That label alone does not say so. The only place we found USP-linked standards in the sources read was for compounded medicines, which need a monograph and a certificate of analysis. [3] Ask a pharmacist.
Is a food-grade oil fine on skin?
Not necessarily. The FDA gives the example of cumin oil, safe in food but able to blister skin. [8]
Does the FDA approve cosmetics before they are sold?
Not generally. Except for color additives, cosmetic products and ingredients do not require FDA approval before they go on the market. [4]
What if a "cosmetic" claims to treat a disease?
The FDA says a product marketed to treat or prevent disease, or affect the body's structure or function (including the skin), is a drug under the law. [5]

The law looks at intended use
The FDA says whether a product is a cosmetic or a drug is determined by its intended use. [4] Intended use can be shown by claims on the label, in advertising or on the internet. [4] A massage oil meant only to lubricate and add fragrance is a cosmetic, but one intended for a therapeutic use such as relieving muscle pain is a drug. [4] The FDA also says the term "cosmeceutical" has no meaning under the law. [4]
Cosmetic products and ingredients, except color additives, do not need FDA approval before they go on the market. [4] The FDA has no list of approved claims for cosmetics. [5] A cosmetic is still considered adulterated if it contains a poisonous or deleterious substance that may injure users under the conditions of use on the label or customary conditions of use. [6] If a product is marketed with claims about treating or preventing disease, or affecting the structure or function of the body, the FDA treats it as a drug. [5]
For supplements, NCCIH says the FDA is not authorized to review dietary supplements for safety and effectiveness before they are marketed. [7]
