What Is Anhydroglucitol?
Anhydroglucitol is a sugar-derived molecule identified scientifically as D-glucitol, 1,5-anhydro-. It is obtained from plant-based glucose sources, most commonly corn or wheat, then refined to remove water at specific positions on the sugar ring. This “anhydro” step gives the ingredient a smaller size and greater stability compared with the original sugar.
Researchers first noted its water-binding talent in the mid-20th century, and by the 1990s formulators began adding it to moisturizers looking for a softer touch than glycerin. Today manufacturers create cosmetic-grade anhydroglucitol through controlled heating and catalytic dehydration of sorbitol, followed by purification to meet skin-care standards.
You will usually spot anhydroglucitol in lightweight face lotions, hydrating serums, sheet masks, scalp-soothing creams and oral care rinses aimed at plaque control. Because it is mild and water-loving, it also shows up in sensitive-skin blends and after-sun gels.
Anhydroglucitol’s Cosmetic Benefits/Uses
In formulas, anhydroglucitol pulls several duties that support both product texture and skin feel:
- Antiplaque: Helps limit bacterial buildup on teeth or skin surfaces, making it useful in mouth rinses and clarifying toners
- Humectant: Attracts and holds moisture from the air, keeping products flexible and boosting skin hydration for a smoother look
- Skin Conditioning: Softens and calms the skin’s surface so it feels supple after application
Who Can Use Anhydroglucitol
Anhydroglucitol suits most skin types including dry, oily, combination and sensitive skin because it hydrates without leaving a greasy film and has a low chance of causing irritation. There are no known concerns for mature or acne-prone complexions either, making it a versatile choice across age groups.
The ingredient is synthesized from plant-derived glucose so it aligns with vegan and vegetarian lifestyles provided the final formula contains no animal by-products.
Current data shows no specific risks for women who are pregnant or breastfeeding when anhydroglucitol is used topically in typical cosmetic concentrations. This is not medical advice and anyone who is expecting or nursing should check with a doctor before adding new products, just to be safe.
Anhydroglucitol does not make skin more sensitive to sunlight and can be worn day or night without altering your usual sun protection routine.
Potential Side Effects/Adverse Reactions
Responses to any skincare ingredient can differ from person to person. The points below outline potential but uncommon side effects linked to topical anhydroglucitol when it is used in cosmetic formulations produced correctly. Most users will not experience these issues.
- Mild redness or warmth at the application site
- Temporary itching or stinging, especially on very compromised skin barriers
- Rare allergic contact dermatitis in individuals sensitive to sugar alcohols
- Sticky or tacky feel if layered heavily or combined with other strong humectants
If you notice any discomfort or irritation stop using the product and consult a healthcare professional if symptoms persist.
Comedogenic Rating
Rating: 0 (non-comedogenic)
Anhydroglucitol is a small water-soluble humectant that does not leave an oily film or form plugs inside pores. It dissolves fully in the water phase of a formula and rinses away without residue, which is why it earns the lowest spot on the comedogenic scale.
This makes it a safe pick for people who are prone to acne or frequent breakouts.
Its sugar-based structure can even help cut surface stickiness when balanced correctly with other ingredients, so it rarely adds to the heaviness that sometimes triggers congestion.
Summary
Anhydroglucitol works mainly as a humectant, skin conditioner and mild antiplaque agent. It attracts moisture into the upper skin layers then holds it there, leaving skin soft and smooth. Its tiny size and full water solubility let it slip into light textures without greasiness, while its ability to curb bacterial film is useful in oral care and clarifying toners.
Although not as famous as glycerin or hyaluronic acid it shows up in a growing number of modern gels, serums and masks aimed at weightless hydration, especially for sensitive users who want something gentler.
Current research and consumer use suggest it is very safe with a low risk of irritation or clogged pores. As with any new skincare addition it is smart to do a quick patch test before full use, just to be sure your skin agrees with it.
