Corn starch is a fine white powder made from maize, used in cosmetics, dusting powders, bath bombs, slime, adhesives and paper and textile sizing.

What is corn starch?
Corn starch is the starch extracted from maize kernels. In Indian kitchens the same type of powder is often sold as cornflour, but Azlok's listing is a cosmetic raw ingredient, not a food product.
- Formula: (C6H10O5)n, a polymer of glucose
- CAS number: 9005-25-8 (starch)
- Appearance: fine, white, odourless powder that squeaks when rubbed
- Solubility: doesn't dissolve in cold water. Heated in water to roughly 62–72 °C, the granules swell and form a thick paste (gelatinisation).
Mixed with a little cold water it makes a thick slurry that turns hard when you hit it and runny when you stop. That's the well-known "oobleck" effect.
Grades and pack sizes at Azlok
Azlok lists Corn Starch Powder in its cosmetic raw ingredients range. It suits powders, bath products, DIY cosmetics and craft work. The listing doesn't state a pack size in its name, so check the product page.
It isn't sold as food grade, so don't use it for cooking. For the current rate, see today's price per kg.
Common uses
- Cosmetics: an oil-absorbing, mattifying powder in dry shampoos, body and face powders, and deodorant bases. It also gives a soft, silky feel to some creams.
- Bath products: a filler and binder in bath bombs alongside baking soda and citric acid.
- Craft and school: oobleck, cornstarch clay and play dough, and simple paste glue.
- Industry: paper sizing and coating, textile sizing, corrugated board adhesives, and as a raw material for glucose syrups and biodegradable plastics.
In powders it's often blended with talc-free bases such as kaolin clay, arrowroot or rice starch. Each gives a slightly different feel, so test blends on a small batch before scaling up.
How to use it
These are common maker recipes. Weigh ingredients for repeatable results.
| Use | Typical recipe |
|---|---|
| Bath bombs | 2 parts baking soda, 1 part citric acid, 1 part corn starch by weight, bound with a little oil and a light water spritz |
| Oobleck | About 1.5 to 2 parts corn starch to 1 part water |
| Dry shampoo or body powder | Used as the main powder base, often blended with clay or baking soda |
- Making a paste: mix the starch with cold water first, then heat while stirring. Dry starch dropped straight into hot water forms lumps.
- In creams: sprinkle it into the oil phase or disperse in a little water before adding, so it doesn't clump.
- Water-based products: starch can feed microbes, so any product containing water needs a suitable preservative system.
- Patch test finished leave-on products before regular use.
Safety and storage
- Low hazard, but avoid breathing the fine dust. Pour gently and wear a dust mask if you're handling a lot.
- Starch dust in air is combustible. Don't sieve or blow large clouds of it near flames or sparks.
- Store it in an airtight container in a cool, dry place. Damp starch clumps and can grow mould.
- Keep it away from children and pets, and away from food storage, since this listing is a cosmetic raw ingredient.
- Small spills: sweep up dry. Wet starch turns into a slippery paste on floors.
- Don't pour large amounts of slurry or oobleck down a sink. It settles and can block pipes. Let it dry and throw it out with solid waste.
Choosing the right grade and pack
- Cosmetic makers: this listing suits powders, bath bombs and DIY cosmetics. Ask for the specification if you need moisture content or microbial limits.
- Schools and crafts: it works well for oobleck, clay and paste.
- Cooking: buy food-grade cornflour from a grocery source instead.
- Production quantities: for 25 kg or more, send a bulk inquiry.
If you sell finished cosmetics in India, keep supplier documents ready, as products must meet BIS and CDSCO rules.
अक्सर पूछे जाने वाले सवाल
- Is corn starch the same as cornflour?
- In India, the white powder sold as cornflour is usually corn starch. In some countries cornflour means finely ground whole maize, which is different. Azlok's corn starch is listed as a cosmetic raw ingredient, so don't use it for cooking.
- How much corn starch goes into bath bombs?
- A common recipe is 2 parts baking soda, 1 part citric acid and 1 part corn starch by weight, plus a little oil and a light water spritz to bind. The starch slows the fizz and helps the bomb hold its shape.
- How do I make oobleck with corn starch?
- Mix about 1.5 to 2 parts corn starch with 1 part water, adding water slowly while stirring. It should feel solid when tapped and flow when you tilt the bowl. Add more starch if too runny and a spoon of water if too stiff.
- Can corn starch be used in dry shampoo?
- Yes. Corn starch is a common base for dry shampoo because it absorbs oil. Dust a small amount at the roots, wait a few minutes and brush out. On dark hair, makers often blend it with a little cocoa powder or clay to reduce the white cast.
- Why did my corn starch paste go lumpy?
- Dry starch added straight to hot water forms lumps because the outside swells before the inside gets wet. Stir the starch into cold water first, then heat slowly while stirring until it thickens.
- Does corn starch go bad?
- Kept dry and airtight, it stays usable for a long time. Damp starch can clump, smell stale or grow mould. Discard it if you see dark spots or a sour smell.
- Is corn starch safe for the skin?
- It's widely used in body and face powders. Patch test any finished product first, avoid using it on broken skin, and remember that water-based recipes with starch need a preservative.
