Agarwood Balm Longevity: Ask About the Base Before the Hours

Someone at the counter held a small tin of balm and asked: This lasts eight hours, right?

I didn't answer directly. I first asked: Does the tin say what the base is?

He said: No. It only says fragrance.

Then that "eight hours" can't be engaged with.

Why it can't be engaged with

A balm isn't just fragrance and wax stirred together. That bit of wax and oil in the paste is like putting a shell around the fragrance molecules. Different shell materials mean different speeds at which the scent escapes and different amounts retained.

In the 2018 review in Cosmetics, there is a sentence that reads:

"the scent of oil-based perfumes lasts for 6–15 h, while those based on alcohol last for about 3 h"

The same paper also states that perfumes release via body heat.

Only by reading these two sentences together is it complete: oil-based perfumes release via body heat and last 6 to 15 hours; alcohol-based ones last about 3 hours.

Please note that this sentence is prefixed by three conditions—oil base, fragrance concentration around 20%, and body-heat release.

If any one of these three conditions is missing, this range cannot be directly transplanted onto another balm.

A lone hour figure cannot be used for price comparison

A common mistake is this: treating "lasts 8 hours" as a metric that can be compared across products.

It is not. Different carriers, different concentrations, and different results when applied to the wrist versus the hem of a garment.

It's the same as using one price to compare two different things. The number itself isn't wrong; the comparison method is.

The same "lasts N hours," if it doesn't specify base, concentration, amount used, and application site, is not a number with a denominator. It's like someone asking me that day, "Is this wooden box more expensive than that one?"—asking if it's expensive first is useless; ask what it is first.

You can read the ingredient list yourself

Article 12 of the Measures for the Administration of Cosmetic Labels stipulates that cosmetic labels shall list all ingredients and "list them in descending order of content in the product formula"; ingredients at 0.1% or less may be introduced as "other trace ingredients."

This is a labeling layout rule and has nothing to do with longevity. But it gives us a ready-made ruler.

Turn to the back and look at the top line of the ingredient list.

If it says beeswax, candelilla wax—wax base. Wax is dense, hard at room temperature, softens with body heat, and the scent seeps out slowly; it will leave an oil mark on clothes.

If it says jojoba oil, coconut oil—oil base. The oil itself carries scent, spreads and dissipates readily, is relatively even, but has short longevity.

If it writes "fragrance" and moves on, followed by a string of "other trace ingredients"—the part that truly fixes the scent is not much.

The order is the order of content. This is regulation, not preference.

So there is one question you shouldn't ask the seller: What percentage of fragrance does it contain?

This number is not separately labeled in the first place; asking is pointless. One question you can ask is: What is the base of your balm?

Usage differences of the three bases

Wax base is the hardest, most durable, and most likely to leave oil marks on clothing. Be mindful around leather bags and cotton-linen fabrics.

Oil base has good spreadability and applies evenly, but its longevity is the shortest of the three. Suitable for daytime reapplication, not for expecting it to last all night.

Paste base falls between the two and is the most common choice on the market.

There is also a common industry line: Natural essential oils last longer.

Whether this is true depends on which layer you mean. Essential oils themselves do change over time, but what determines longevity is the base, not the word "natural." Whether the paste should be wax or oil, that order cannot be hidden.

Another line is fragrance concentration. With the same oil base, higher concentration lasts longer, and lower concentration doesn't last much longer. Concentration is not labeled on the tag, so any claim about specific duration must first answer three things: what base, what concentration, and where applied.

If all three questions cannot be answered, that hour figure is just a number.

What you can do is look at that line

Next time you get a balm, don't try the scent first.

Turn to the back first and see what the top line of the ingredient list says.

Wax base, oil base, paste base—choose one of three.

Report this base on zgcx.net.cn, and based on the one in your hand, I will make a comparison table of the three types' usage, longevity differences, and whether they leave marks on clothes.
