For royal icing, liquid glucose or light corn syrup are excellent substitutes for Glycerin if you're aiming for a soft set and a shinier finish. These alternatives really help keep the icing from getting too brittle, just like glycerin does.
What can I use instead of glycerine?
Propylene glycol is a common substitute for glycerin, especially in cosmetic and toiletry products, thanks to its similar moisture-attracting properties.
This stuff, also known as PG, is a colorless, odorless liquid that's really good at drawing in and holding onto moisture. You'll find it used a lot as a humectant and solvent across different industries. Now, if you're thinking about food applications, you absolutely need to double-check that any substitute is clearly labeled as food-grade. Not all forms are safe to eat, as the FDA points out.
Why do you need glycerin in royal icing?
Glycerin is primarily needed in royal icing to prevent it from setting too hard and becoming brittle, which gives it a softer, more pliable texture.
Its humectant properties really help keep moisture in the icing, making it much easier to cut through without cracking. Plus, it gives it a nice subtle sheen! Beyond royal icing, glycerin also prevents sugar from crystallizing in candies and keeps baked goods moist for longer, which is honestly a huge win for texture and freshness.
Can I use coconut oil instead of glycerin in royal icing?
No, you generally can't use coconut oil directly as a substitute for glycerin in royal icing.
While vegetable glycerin is often made from oils like palm, coconut, or soybean (less commonly), the best substitutes for vegetable glycerin are actually other forms of glycerin itself. This includes animal-based or synthetic glycerin. You can use these in the same amounts as vegetable glycerin in your recipes, and they'll give you the same results. So, stick to actual glycerin, not the raw oil!
Can I use sugar instead of glycerin?
No, you generally can't use sugar as a direct substitute for glycerin to achieve the same effects in royal icing.
Glycerin, which you'll find in things like soap, toothpaste, and other pharmaceutical products, actually functions quite differently from sugar. While glycerin can be used as a sugar substitute in some baked goods (which is interesting, right?), it doesn't work the other way around for royal icing. Sugar is already the main component of royal icing, and adding more won't give you the same anti-brittle, pliable texture that glycerin provides.
Does glycerine make icing hard?
No, quite the opposite! Glycerine actually prevents your royal icing from setting hard and dry, while also adding shine.
Just a touch of it makes the icing much easier to apply to cakes. It also helps ensure you get a nice smooth cut when you're slicing. For a softer set, try adding 1 teaspoon of glycerine for every 500g of icing sugar. If you're after a really glossy finish, bump that up to 2 teaspoons per 500g.
Can I use baby oil instead of glycerin?
No, you absolutely cannot use Baby oil instead of glycerin in royal icing.
Baby oil (which is typically mineral oil) is not food-grade and is definitely not safe for consumption. The original text mentions using mineral oil or baby oil as a substitute for distilled water and glycerin when making decorative "snow" in a jar (like for a snow globe, presumably). That's a completely different application! For anything edible like royal icing, you must stick to food-grade ingredients.
How do you make homemade bubbles without glycerin?
You can make homemade bubbles without glycerin using just water, dish soap, and sugar.
- First, grab a small bowl and add the water, then pour in the dish soap.
- Next, add the sugar and stir gently until it's completely dissolved. Voila! Your bubble solution is ready to go – time for some fun!
- Finally, put on some winter gloves (this helps prevent bubbles from popping too fast) and gently blow bubbles using your bubble wand. See? That was super quick!
Can I make glycerin at home?
Yes, you can definitely make glycerin at home!
While you can certainly make it from vegetable oils or just buy it at the store, it's often much cheaper and easier to whip up from leftover animal fat you get from regular cooking. The process involves rendering the fat, adding lye to turn it into soap, and then breaking down that mixture with salt. You can actually make your own glycerin at home in just a few hours.
Is there a difference between glycerin and vegetable glycerin?
Yes, but generally speaking, glycerin and vegetable glycerin are usually the same thing.
Some hair care companies might specify the source of their glycerin, listing it explicitly as "vegetable glycerin." However, in most cases, if a product just says "glycerin," it's probably derived from vegetables anyway. The bottom line is, glycerin—no matter its source—acts as a humectant in most products.
Is glycerin an olive oil?
No, glycerin is not olive oil, but it's a component found within olive oil's structure.
Think of it this way: olive oil is a triacylglyceride . That's essentially three fatty acids connected to a glycerol backbone (which is what glycerin is!). So, technically, olive oil is a type of glycerolipid. Triacylglycerols (also known as triglycerides or just fats) are super important, serving as the main energy reserve for both plants and animals.
Is liquid glucose the same as glycerine?
No, liquid glucose and glycerine are not the same thing.
While both are liquids, glycerine is a colorless and odorless oil. Glucose, on the other hand, is actually a liquid sugar . They have different chemical compositions and functions, especially in baking and confectionery.
Why glycerin is bad for you?
When ingested in large amounts, vegetable glycerin can cause some uncomfortable side effects.
For some people, taking it internally might lead to headaches, dizziness, nausea, vomiting, and even excessive thirst (13). The thing is, glycerin is a type of sugar alcohol that your body doesn't fully absorb. So, if you consume too much—whether by itself or in foods—you might also experience issues like gas and diarrhea. It's usually best to use it in moderation!
How do you make liquid soap without glycerin?
You can make liquid soap without adding extra glycerin by dissolving bar soap in water.
To do this, you'd typically grate some bar soap into water. Then, bring that mixture to a boil, reduce the heat, and cook it over a medium-low heat for 1-2 minutes until the soap completely dissolves. While you can certainly make liquid soap without *extra* glycerin (since regular bar soap already contains some), adding a little bit more can actually make your liquid soap creamier and help prevent clumps. So, it's really up to you!
What are the side effects of glycerin?
When ingested, glycerin (or glycerol) can cause side effects like headaches, dizziness, bloating, nausea, vomiting, thirst, and diarrhea.
Now, if you're applying it to your skin, glycerol is generally considered LIKELY SAFE. However, even on the skin, it might occasionally cause some redness, itching, or a burning sensation for some people. So, it's always good to do a patch test if you're unsure!
