Banned azo dyes
All 24 banned amines · lab sample CEO-282
Dated 21 September 2026Lab reports · Mulberry silk
Skin-friendly silk, tested by a government lab. Here's everything it said.
In September 2026, a sample of the mulberry satin silk we make Wildpetal and Mushbloom from went to the Regional Laboratory of the Textiles Committee in Kolkata, under the Ministry of Textiles, Govt. of India. Two reports came back. This page shows what was tested, what was found, and how to read it yourself, fine print included.
In short
Read the original reports ↓
Our silk is skin-friendly, and these reports are why we can say so. The Textiles Committee, Govt. of India, found no banned azo dyes and no detectable formaldehyde in it, measured a near-neutral pH of 7.31, and graded its colour 5 of 5 against sweat and 5 dry, 4–5 wet against rubbing. Those are the checks that matter for something worn against skin. The sample was in Wildpetal's colour; Mushbloom and the Essentials, Candy Pop and Candy Dot, are cut from the same silk in other colours.

Dated 21 September 2026What it adds up to
Skin-friendly. Here's why we can say it.
- No banned azo dyes. Nothing harmful comes out of the colour.
- No formaldehyde. No harsh finishing chemicals left in the cloth.
- A near-neutral pH of 7.31. Gentle, not acidic or alkaline.
- Colour 5 of 5 against sweat. It stays in the silk, not on your skin.
"Skin-friendly" is our conclusion, drawn from the lab's numbers. The lab tests and reports; it doesn't hand out labels. That's why every number is on this page, for you to check.
Why it carries weight
Not our word. A government lab's.
01
Nobody here can nudge the result.
The Textiles Committee is a statutory body, set up by an Act of Parliament in 1963 and run under the Ministry of Textiles, Govt. of India. We sent the cloth and paid the testing fee, like anyone can. What came back is theirs, not ours.
02
Methods the whole world uses.
Each check follows a published international (ISO) method or Indian law, so a 5 here means the same as a 5 anywhere else, and "not detected" means the same limit every time.
03
Signed, numbered, dated.
Every report carries its own number and date, the laboratory's stamp, and the signature of its Quality Assurance Officer. Numbers you can hold us to.
The five checks
What was tested, and what it means for you.
Banned azo dyes
ResultNot detected
What it checks
Azo dyes are a big family of dyes, and most are fine. A few can break down into chemicals called aromatic amines, some of which are harmful, so Indian law bans the dyes that release them. The lab looked for all 24 of those amines in our silk.
Why it matters to you
Wildpetal sits against your scalp and your wrist for hours, through warm days and sweaty ones. A banned dye has no business being that close.
All 24 amines, one by one Each came back under 30 mg/kg, the level at which the test counts it as present. The total came to nil.

How to read it. "Not detected" means every amine was under 30 mg/kg. "Detected" would mean a banned dye had been used. Tested under the Environment (Protection) Act, 1986 and its Rules · Report TC/ST/CEO/282/2026-27.
Formaldehyde
ResultNot detectable
What it checks
Formaldehyde is sometimes used in finishing, to stop cloth creasing or to hold colour in. It can irritate skin and eyes. The lab measured both kinds, the free and the bound.
Why it matters to you
Something you wear every day shouldn't carry finishing chemicals into your hair. Ours carried none the test could find.
Not detectable
Detectable
How to read it. "Not detectable" means the test found none at the smallest amount it can measure. Method ISO 14184-1:2011 · Report TC/LC/ST/1008/2026-27.
pH
Result7.31
What it checks
pH measures how acidic or alkaline something is, from 0 to 14, with 7 as neutral. The washing, dyeing and finishing a cloth goes through can leave it pushed too far one way or the other.
Why it matters to you
Cloth that's far from neutral can feel harsh against skin. Close to neutral is the gentle place to be, and that's where ours landed.

How to read it. 7.31 is a touch above 7, which is close to neutral. Measured at 27.2 °C. Method ISO 3071 · Report TC/LC/ST/1008/2026-27.
Colour and sweat
Result5 of 5
What it checks
The lab soaks the silk in artificial sweat, in two versions because real sweat can be either acidic or alkaline. It presses the silk against white silk and white cotton, warms it, and grades two things: did our colour change, and did any of it move onto the white cloth.
Why it matters to you
Hot days, long days, a bun that's been up since morning. On these grades, the maroon stayed in the silk.
| What's graded | Grade |
|---|---|
| Our colour, changed? | 5 no change |
| Stain on white silk | 5 none |
| Stain on white cotton | 5 none |
- 1 a lot
- 2 plenty
- 3 some
- 4 slight
- 5 none
How to read it. Grades run from 1 (a lot) to 5 (none). Our silk scored 5 on every line, in acidic and alkaline sweat alike. Method ISO 105-E04:2008 · Report TC/LC/ST/1008/2026-27.
Colour and rubbing
Result5 dry · 4–5 wet
What it checks
A machine rubs a square of white cotton back and forth over the silk, once dry and once wet, along both directions of the weave. Then the lab grades how much colour came off onto the cotton.
Why it matters to you
Silk brushes against your hands, your hair and your sleeves all day. On these grades, nothing came off dry, and at most a faint trace when wet.
| Direction | Stain on white cotton |
|---|---|
| Along the warp | 5 none |
| Along the weft | 5 none |
- 1 a lot
- 2 plenty
- 3 some
- 4 slight
- 5 none
How to read it. 5 is no staining at all; 4–5 sits between "slight" and "none". Method ISO 105-X12:2016 · Report TC/LC/ST/1008/2026-27.

The fine print, up front
What these reports are, and what they aren't.
They are
- Independent lab tests of a sample of the mulberry satin silk we make Wildpetal and Mushbloom from, in Wildpetal's colour.
- Done by the Regional Laboratory of the Textiles Committee, Kolkata, between 11 and 21 September 2026.
- Five checks, with every result shown on this page.
They aren't
- A certificate. They're test results, not a stamp of approval on a product.
- A test on skin. The lab tested cloth, not people.
- A test of every colour. Mushbloom is the same silk in another colour, so the dye results (azo dyes, sweat, rubbing) speak for the colour tested.
- A test of everything. They cover the silk, not Wildpetal's cotton lace or elastic, and not our other pieces.
- A sample the lab picked. We sent it in, and in the lab's own words, results relate only to the samples tested.
Questions people ask
Short answers, from the reports.
Is your silk skin-friendly?
Yes. A Govt. of India lab found no banned azo dyes and no detectable formaldehyde in our silk, a near-neutral pH of 7.31, and colour that held 5 of 5 against sweat. Those are the checks that matter for something worn against skin, which is why we call it skin-friendly. That is our conclusion from the lab’s results: the lab reports results and doesn’t issue labels.
Are Moosi Creatures silk scrunchies lab-tested?
Yes. In September 2026 the mulberry satin silk we use was tested by the Regional Laboratory of the Textiles Committee in Kolkata, part of the Ministry of Textiles, Govt. of India. No banned azo dyes were found, formaldehyde was not detectable, the pH was 7.31, and the colour scored 5 of 5 against sweat, and 5 dry and 4–5 wet against rubbing.
Who is the Textiles Committee?
A statutory body set up under the Textiles Committee Act, 1963, and run under the Ministry of Textiles, Govt. of India. It tests textiles for quality across India. Our silk was tested at its Regional Laboratory in Kolkata.
Is your silk free of banned azo dyes?
In the sample tested, yes. All 24 amines banned under India’s Environment (Protection) Rules came back under 30 mg/kg, which the report records as not detected, meaning no prohibited azo dyes could be found. Report TC/ST/CEO/282/2026-27, dated 21 September 2026.
Will the colour run onto my hair, skin or clothes?
The tested silk scored 5 out of 5 for colour-fastness to perspiration, with no staining on white silk or cotton, and 5 dry and 4–5 wet for rubbing. A 5 means no staining at all. Report TC/LC/ST/1008/2026-27, dated 21 September 2026.
Which Moosi pieces are made from this silk?
Wildpetal, the five-petal plaid scrunchie, is made in the colour the lab tested. Mushbloom, the hand-stitched round, is cut from the same mulberry silk in another colour, edge and tie included. So are the Essentials: Candy Pop, the big scrunchie, and Candy Dot, the thin one, in Antique White and Hot Pink. For the pieces in other colours, the dye results speak for Wildpetal’s colour.
Can I read the original reports?
Yes. Both reports are on this page, shown with the Textiles Committee’s consent, exactly as they were issued, with their numbers and dates.
Is this a certificate?
No. These are test results for a sample we sent in, not a certification of a product. In the lab’s own words, the results relate only to the samples tested.
