Reasons Why Aloe Vera Gel Might Smell Bad
Aloe vera gel is known for its many health and skin benefits. However, you may have noticed that sometimes the gel has an unpleasant odor. There are a few reasons why your aloe vera gel might start smelling bad.
Expired or Spoiled Gel
Like any plant product, aloe vera gel has a shelf life. The nutrients and compounds that give it benefits also make it prone to spoiling after some time. If your gel is expired, the scent can turn more bitter, acidic or fermented.
Aloe gel in a squeezable tube may last 6-12 months after opening if refrigerated. Homemade gel from fresh leaves only lasts 1-2 weeks in the fridge.
If your gel is discolored, separating or growing mold, it has gone bad and should be discarded.
Bacterial Contamination
The moist, nutrient-rich environment of aloe gel allows bacteria to grow easily. Pseudomonas aeruginosa and Escherichia coli are two common culprits.
Without proper sanitization, bacteria from your hands, utensils or storage container can transfer into the gel. Once contaminated, you may notice foul odors.
Oxidation
Exposure to air causes aloe gel to oxidize over time, especially if left at room temperature. Oxidation breaks down nutrients but also releases compounds that give off stronger smells.
Storing gel in the fridge in an airtight container helps limit oxidation and preserves freshness longer.
Certain Chemical Reactions
Compounds naturally present in aloe vera leaves can produce sulfur-like odors when they chemically break down through aging and oxidation.
For example, the enzyme alliinase converts amino acids like cysteine into disulfide compounds. This releases gases that smell like rotten eggs or garlic.
Aloe Latex Contamination
Aloe latex is a yellowish fluid from underneath the plant's outer rind. It has a very bitter, unpleasant taste and odor.
If latex leaks into the clear inner gel, even small amounts can taint the flavor and cause a bad smell.
Tips to Prevent Your Aloe Gel From Smelling Bad
You can take steps to keep your aloe vera gel fresh and odor-free for longer:
Wash the Leaves First
Rinse aloe leaves with water before cutting to remove dirt and bacteria from the skin. Scrub with a vegetable brush if needed.
Use Clean Utensils
Wash knives, containers, and hands thoroughly before handling gel to prevent contamination.
Avoid the Yellow Latex
When fileting the leaves, carefully scrape away the bitter yellow fluid under the skin.
Extract Gel Properly
Removing gel too closely to the green rind may allow latex to leach into the fillet. Leave some clear gel attached to the skin.
Store in An Airtight Container
Cover gel in an airtight jar or squeeze bottle to block air and slow oxidation.
Refrigerate
Chilling gel in the fridge at 40F or below helps curb bacteria growth and enzymatic reactions.
Use Fresh Leaves
Process leaves within 1-2 days of cutting. The older the leaf, the faster the gel deteriorates.
Avoid Contaminating the Gel
Never touch gel with dirty hands or double dip with utensils. Keep applicators and containers clean.
Make Small Batches
Gel made in large volumes spoils faster. Refrigerate smaller batches for 1-2 week use.
Check Expiration Dates
Store-bought gel usually lasts about a year unopened, or 6-12 months opened. Toss old product.
How to Tell When Your Aloe Gel Has Gone Bad
Be on the lookout for these signs that indicate your aloe vera gel has spoiled:
Change in Scent
Fresh aloe has a mild, herbal aroma. Foul odors like sulfur, vinegar or ammonia mean it's gone off.
Change in Color
Clear gel that becomes yellow, brown or gray has oxidized. Also watch for pink, blue, green or black discoloration from mold.
Change in Texture
Healthy gels are smooth and uniform. Separation, sliminess, mushiness, dryness, or chunks of precipitate indicate spoilage.
Change in Taste
Rancid, bitter, or sharp flavors signal the gel is no longer good to use.
Mold Growth
Fuzzy or slimy mold growing on the gel's surface means it's well past safe to use and should be thrown away.
Is It Safe to Use Aloe Gel That Smells Bad?
It's not recommended to use aloe vera gel with an off or foul odor. Spoiled gel often lacks the beneficial compounds like vitamins, antioxidants, enzymes, and polysaccharides that make it effective.
More concerning is the potential presence of harmful bacteria like pseudomonas, E. coli, and mold that can cause infections or toxicity when applied to skin or ingested.
Rancid aloe vera gel is best avoided. Any batches with an unpleasant scent or other signs of spoilage should be discarded.
Tips for Choosing High Quality Aloe Gel
To ensure youre getting a fresh product, look for aloe vera gel that:
Comes from Organic, Homegrown Leaves
Small batch gel made from homegrown or locally farmed leaves retains more nutrients than mass manufactured products.
Is Cold Pressed and Unfiltered
Minimal processing preserves the gel's beneficial enzymes, polysaccharides, and antioxidants.
Contains Natural Preservatives
Citric acid and ascorbic acid help extend shelf life without compromising quality.
Doesnt Contain Added Color, Fragrances, or Thickeners
Avoid aloe gels with artificial ingredients which can diminish benefits and irritate skin.
Is Sold Refrigerated
Chilled gel has a longer shelf life. Make sure it's not sitting at room temperature on store shelves.
Comes in Opaque, Air-Restrictive Bottling
Dark glass or plastic bottles prevent light exposure and oxygenation to keep gel fresher longer.
Natural Alternatives If You Don't Have Fresh Aloe
If you don't have an aloe plant on hand or access to high quality gel, some natural alternatives provide similar hydrating and soothing benefits:
Coconut Oil
Has anti-inflammatory, antimicrobial, and hydrating properties to heal skin.
Honey
Soothes burns, wounds cuts, and dry skin; has antibacterial action.
Apple Cider Vinegar
Balances skin pH, fights acne, and reduces irritation.
Green or Black Tea
Tannins and antioxidants reduce inflammation, redness and puffiness.
Cucumbers
Hydrates and cools irritated skin; calms puffy eyes.
When to See a Doctor
While using spoiled aloe vera gel may simply result in skin irritation for most people, see your doctor if you experience:
- Signs of infection like redness, swelling, oozing, fever
- Rash, hives, or blistering
- Difficulty breathing or swallowing
- Vision changes or eye irritation
These could indicate a more serious reaction, especially if consumed internally. Seek prompt medical treatment in those cases.
