Cornstarch is a widely utilized ingredient derived from the starchy part of corn kernels, specifically the endosperm. It's commonly employed as a thickening agent in a variety of culinary creations, including gravies, marinades, sauces, soups, and casseroles, enhancing their texture and consistency. While many may associate cornstarch primarily with cooking, its versatility extends far beyond the kitchen. However, it's important to note that numerous applications of cornstarch in household tasks may lack rigorous scientific support.

Here, we present 19 innovative household uses for cornstarch.

1. Skin Relief

Cornstarch (known as makki ka atta in India) serves as an affordable and readily available remedy for various skin irritations, even though scientific studies validating its effectiveness are limited. Nevertheless, a significant number of individuals turn to it for relief from sunburn and to alleviate skin itchiness.

To utilize cornstarch, combine it with a few drops of water in a bowl until a paste with a consistency similar to peanut butter is achieved. Gently apply a thin layer of this mixture onto the affected area of your skin and allow it to dry completely. Once dried, rinse it off using warm water for soothing relief. Additionally, many people find it beneficial to sprinkle cornstarch on their bed linens or inside clothing to minimize friction and enhance comfort.

2. Deodorant

If you find yourself without deodorant or are interested in a homemade alternative, consider using cornstarch (corn flour) as an effective solution. Due to its excellent moisture-absorbing capabilities, cornstarch serves as a natural deodorant, helping to minimize both sweat and odor.

To create your very own cornstarch deodorant, gather the following ingredients:

• 3 tablespoons (45 mL) of coconut oil
• 2 tablespoons (16 grams) of cornstarch (corn flour)
• 2 tablespoons (28 grams) of baking soda

Begin by microwaving the coconut oil for about 15–20 seconds or until it transforms into a liquid state. Gradually mix in the cornstarch and baking soda until you achieve a thick paste. For a refreshing scent, feel free to incorporate a drop of your preferred essential oil. However, it’s important to note that some individuals may find baking soda irritating to their underarms, making it unsuitable for everyone. Additionally, if you are dealing with excessive sweating or hyperhidrosis, you might require a more potent commercial antiperspirant.

3. Dry Shampoo

Cornstarch serves as an excellent natural alternative for dry shampoo. To use, simply sprinkle a small quantity onto the roots of your hair and then gently distribute it all the way to the ends. For a more precise application, a clean makeup brush works wonders in transferring the cornstarch to your roots effectively. However, it's worth noting that due to the light color of cornstarch, this method may not be suitable for individuals with darker hair tones.

4. Matte Nail Polish

Creating a unique matte nail polish at home is quite simple and fun! Begin by dispensing a few drops of your chosen nail polish onto a clean plate. Next, lightly sprinkle a small quantity of cornstarch (known as makai ka atta in India) over the polish. It's advisable to start with less, gradually adding more until you achieve the desired matte effect. Once you've blended the ingredients thoroughly using a paintbrush, you can proceed to apply this mixture to your nails for a chic, matte finish.

5. Soothing Milk Bath

Milk baths have been embraced across cultures for their ability to calm the skin while offering an indulgent bathing experience. A fascinating addition found in many milk bath recipes is cornstarch, which is believed to enhance the soothing properties. While scientific evidence supporting the benefits of cornstarch in milk baths is scarce, numerous individuals report positive effects from its use.

To prepare this luxurious bath soak, combine 100 grams (approximately ¾ cup) of cornstarch, 200 grams (about 2 cups) of powdered whole milk, and 50 grams (around ½ cup) of baking soda in a resealable bag. Make sure to seal the bag tightly and shake it vigorously to blend the ingredients thoroughly. For an aromatic touch, add a few drops of lavender essential oil — or your preferred essential oil—and give it another shake. When it’s time to unwind, simply add 100 grams (one cup) of this mixture to your warm bath water and indulge in a soothing soak.

6. Preventing Athlete’s Foot

Athlete’s foot is a fungal infection that arises when feet are frequently subjected to moisture—primarily from sweat—creating an ideal environment for fungi such as Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum to thrive. This condition is common among athletes and those who spend extended periods in damp footwear. While cornstarch (makai ka atta) cannot directly treat or eliminate athlete’s foot, it serves as an effective preventive measure. By sprinkling cornstarch inside your shoes, you can significantly reduce moisture levels. Alternatively, adding it to your socks enhances moisture-wicking properties, keeping your feet dry and comfortable. For those who frequently suffer from athlete’s foot, it is advisable to consult with your healthcare provider regarding effective treatments, which may include topical antifungal medications to combat the infection.

7. Chafing Solution

Cornstarch, known as makai ka aata in India, is an effective remedy that can assist in minimizing friction between two surfaces, which can consequently alleviate the discomfort of chafing. To use, simply apply a small quantity of cornstarch to the affected areas, like the skin between your thighs, before putting on your clothing.

8. Natural Solution for Hair Knot Detangling

When faced with stubborn knots in your hair, a beneficial remedy is to apply cornstarch directly to the affected area. This natural agent can significantly reduce friction and help to lubricate hair fibers, ultimately making the process of detangling those knots much simpler.

9. Bug Bite Relief

Bug bites can be not only itchy but also extremely annoying, especially when your skin is moist. To alleviate this discomfort, cornstarch (known as makki ka atta in India) can be a helpful remedy as it assists in absorbing excess moisture from the skin surrounding the bite, thereby reducing the urge to scratch.

To prepare this soothing treatment, combine approximately 16 grams (2 tablespoons) of cornstarch with a few drops of cold water until you achieve a paste that resembles the consistency of peanut butter. Apply this paste directly onto the affected area and allow it to dry completely for optimal relief.

10. Relief from Blisters

Blisters can become more severe in damp conditions or when they rub against surrounding surfaces, such as footwear or garments. To alleviate discomfort, sprinkle a small quantity of cornstarch (known as 'makai ka atta' in India) onto the blistered area. This helps to minimize friction and maintain dryness, promoting comfort. However, it is crucial to avoid applying cornstarch to an open blister or any wound, as this may increase the risk of infection.

Additional Uses

1. Untangling Knots. Cornstarch can effectively minimize friction between fibers, shoelaces, and ropes, making it easier to untangle knots.
2. Silverware Polishing. Combine cornstarch with water in a small bowl. Using a damp cloth, apply this mixture to silverware to unveil its natural luster. Don't forget to rinse the silverware thoroughly afterward.
3. Ironing Starch. For a natural starch alternative when ironing your clothes, mix 475 mL of warm water with 8–16 grams of cornstarch in a spray bottle. Spray it on your clothes and allow it to rest for a minute before proceeding to iron.
4. Enhanced Grip. To improve grip while playing tennis or using various sports equipment, sprinkle a little cornstarch on your hands to combat sweaty palms and enhance your hold.
5. Effective Stain Remover. For oily stains, generously sprinkle cornstarch over the affected area and let it sit for 10–15 minutes. Afterward, wipe it off and treat the stain with a stain remover.
6. Carpet Freshening. Disperse cornstarch on your carpet and let it settle for 30 minutes. Once time is up, simply vacuum it up as you normally would.
7. Cleaning Stuffed Animals and Fabrics. Apply a small quantity of cornstarch to the stuffed animal or fabric, allowing it to remain for 5 minutes. Then, gently wipe it away using a damp cloth.
8. Grease Removal from Walls. Take a small cloth, apply cornstarch, and gently rub the grease until it lifts off.
9. Dry Bath for Pets. If your furry friend is a bit overdue for a bath, sprinkle a small amount of cornstarch into its fur. This acts as a dry shampoo, absorbing unpleasant oils.

When to Avoid Using Cornstarch

While various natural health websites suggest that cornstarch can be beneficial for treating cuts and wounds, it is advisable to steer clear of applying it directly on any open wounds. The reason behind this caution is that cornstarch may create an environment conducive to bacterial growth, potentially leading to infection in the affected area.

Additionally, utilizing cornstarch as a natural makeup or oil remover on your face is not recommended. Although many individuals may find it harmless, it has the potential to clog pores, particularly in those who are prone to acne breakouts, thus aggravating the skin condition.

The Bottom Line

Cornstarch, a highly adaptable ingredient, is celebrated for its remarkable thickening abilities and moisture-absorbing qualities. This pantry staple boasts a variety of household applications, including alleviating irritated skin, untangling hair knots, serving as a natural deodorant, and effectively tackling stains. The next time you find yourself without an essential household item, consider reaching for cornstarch as a practical alternative. However, it is crucial to note that cornstarch should not be applied to open wounds, nor should it be used on facial skin.
