Sulfur is a Mineral supplied by MakeYourSkin as powder / liquid depending grade for professional cosmetic formulation. Used worldwide across mainstream cosmetic formulation, it is valued for keratolytic / sebum / antimicrobial.

What is Sulfur?

Sulfur is supplied under the INCI / technical name Sulfur and carries CAS number 7704-34-9.

It belongs to the Mineral group and is available from synthetic, nature-identical, botanical or biotech routes depending on the grade ordered. The material reaches you as powder / liquid depending grade. It is a specialty material: expect a narrower supplier base, longer lead times and grade-to-grade variation.

Key Properties & Benefits

• Keratolytic / sebum / antimicrobial
• Supplied cosmetic grade with a Certificate of Analysis for every batch.

Uses & Applications

Sulfur is used in blemish serums, spot treatments, mattifying moisturisers, clay masks, purifying cleansers and toners.

Typical applications from the catalogue record: Blemish care, scalp, deodorant where appropriate.

In leave-on skincare it is normally dosed into a serum, ampoule or moisturiser where contact time is long enough for the claim to hold up. In rinse-off formats it is used at a lower level for label presence and sensory contribution rather than measurable performance.

How to Use — Recommended Use Level

General rule: always begin at the lower end of the range, confirm the level against the supplier technical data sheet, and validate stability, pH, colour, odour and preservative efficacy on the finished formulation before scaling up.

Technical Specification

Regulatory Note

Sulfur is a cosmetic ingredient in many markets but a US OTC acne drug active at 3–10%. An acne claim can move the product into drug territory. Confirm classification, concentration and claim language.

Supplier diligence required: Cosmetic/drug claim boundary review where applicable.

Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.

Disclaimer & Caution in Use

For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished cosmetic, and it is not intended for undiluted application to skin, for ingestion, or for any medicinal purpose. Wear gloves and eye protection when handling, avoid raising dust with powders, and keep out of reach of children and pets. Always run a patch test on the finished formulation, and validate stability, compatibility, pH and preservative efficacy before sale. Information supplied is offered in good faith as formulation guidance and does not constitute a safety assessment, a regulatory approval or a medical claim.

Fine powder — avoid generating and inhaling dust. Use local exhaust ventilation or a suitable respirator when weighing, and wet the powder into the formulation phase rather than dry-blending in open air.

Restricted or high-diligence material. Confirm your legal position in every destination market before ordering. Supplied on the understanding that the buyer holds responsibility for compliant use, permitted concentration and claim wording.
