Soap Grades Explained: What Grade 1, 2 and 3 Mean in India
In India, toilet soaps are graded by Total Fatty Matter (TFM) under IS 2888:2004: Grade 1 needs at least 76% TFM, Grade 2 at least 70% and Grade 3 at least 60%. The grade tells you how much of the bar is genuine soap; it does not, on its own, tell you about fragrance, mildness or herbal content.
Where do soap grades come from?
The Bureau of Indian Standards publishes IS 2888:2004, the standard for toilet soap. It sets minimum TFM levels and other quality limits, and the Department of Consumer Affairs has published a consumer leaflet explaining these grades (Toilet soaps leaflet). Bars that do not meet the 60% minimum, or that are made with synthetic detergents, are usually sold as bathing bars under IS 13498 instead.
Grade 1, 2 and 3 at a glance
| Grade | Minimum TFM | What it means in practice |
|---|---|---|
| Grade 1 | 76% | Mostly soap; usually firmer and longer-lasting, less filler |
| Grade 2 | 70% | Good soap content with a little more room for fillers and water |
| Grade 3 | 60% | More filler or water; often softer and wears down faster |
| Bathing bar | Not graded the same way | Low-TFM or synthetic-detergent bars under IS 13498 |
What makes up the rest of the bar?
If a bar has 76% TFM, the other 24% is a mix of water, glycerin, fragrance, colour, preservatives and sometimes fillers such as talc, starch or clay. Some of these are useful: glycerin is a moisturising ingredient, not a filler. So two bars with the same grade can still feel quite different. For a simple explanation of the number itself, see what is TFM in soap.
Does a higher grade mean a better soap?
For value, usually yes: you are paying for more soap and less bulk, and a firmer bar tends to last more baths. For skin feel, not automatically. A very high-TFM soap with harsh fragrance may suit you less than a well-made Grade 2 bar. Use the grade as a starting filter, then look at the oils and additives.
How do common brands line up?
Since grades are printed on wrappers, shoppers often compare them. The figures below are commonly reported TFM ranges (check the current wrapper), shown to illustrate how one shelf can span every grade:
| Brand | Commonly reported TFM (check the current wrapper) | Grade range this suggests |
|---|---|---|
| Mysore Sandal Soap | ~78-80% | Grade 1 |
| Santoor | ~72-76% | Grade 2 to Grade 1 |
| Dettol Original | ~70-76% | Grade 2 to Grade 1 |
| Lux | ~70% | Grade 2 |
| Medimix (classic) | ~60-62% | Grade 3 |
| Lifebuoy | ~60-65% | Grade 3 |
| Pears, Dove | Commonly sold as bathing/beauty bars | TFM-type rating not applicable in the same way |
Every one of these brands is widely used and trusted by many families. A Grade 3 bar is a legitimate product made to a standard; it simply contains a smaller share of soap.
How to use grades when you buy
- Check the product type. Grades apply to toilet soaps. If it says "Bathing Bar", compare it on other points. Our guide to toilet soap vs bathing bar explains why.
- Compare price per 100 g within the same grade. A cheaper Grade 3 bar may wear out faster than a Grade 1 bar of the same weight.
- Read the base oils. Coconut, palm, sesame and others change lather and feel.
- Consider your skin. If you react to fragrance, a lightly scented bar matters more than an extra few points of TFM.

Can a soap be above 80% TFM?
Yes. Bars made with whole oils and very little filler, such as many cold-process soaps, can sit well above the Grade 1 line. The standard sets a minimum, not a maximum. Note that above a point, extra TFM matters less than how the oils are balanced and whether glycerin is kept.
Key takeaways
- Grade 1 is 76%+ TFM, Grade 2 is 70%+, Grade 3 is 60%+ (IS 2888:2004).
- Bathing bars are a separate category and are not graded the same way.
- Higher grade usually means more soap per rupee, not automatically a better skin feel.
- Always confirm the figure on the current wrapper.

Frequently asked questions
What is the TFM of a Grade 1 soap?
At least 76% under IS 2888:2004. Many Grade 1 soaps are higher than this minimum.
Is Grade 3 soap safe to use?
Yes. Grade 3 is a legitimate standard for toilet soap; it simply has less soap (60%+ TFM) and more of other ingredients.
Why does a bathing bar have no grade?
Bathing bars fall under a different standard, IS 13498, and often use synthetic detergents, so TFM grading is not applied the same way.
Where can I see the official TFM rules?
The Department of Consumer Affairs leaflet on toilet soaps summarises the IS 2888:2004 grades.
