Understanding Safety Data Sheets: A Practical Guide for Nail Technicians

Every professional nail product comes with a Safety Data Sheet (SDS) — and if you work in a salon, you're legally required to have them on hand. But most nail techs either never look at them, or open one and immediately close it again because it reads like an industrial hazard manual.

This guide will change that. Here's everything you actually need to know about reading and using an SDS in a salon context.

 

What Is an SDS?

A Safety Data Sheet is a standardised document that provides detailed information about a product's ingredients, hazards, safe handling, storage, and emergency procedures. They're a legal requirement across Australia, regulated under the Work Health and Safety (WHS) Act.

Every SDS follows the same 16-section format globally — which makes them consistent, but also dense. The good news is that as a nail technician, you don't need to understand all 16 sections equally. Some are written for industrial-scale use and simply don't apply to a salon environment.

Here's what you actually need to focus on.

 

The Sections That Matter Most to You

Section 1 — Identification

This tells you the product name, the supplier, and their contact details. Useful for confirming you have the right SDS for the right product, and for knowing who to call if something goes wrong.

One thing worth checking: the issue date. SDS documents should be reviewed and updated regularly. If yours is more than five years old, it's worth requesting a current version from your supplier. Planet Nails SDS documents are available to download directly from our website and are kept up to date.

 

Section 2 — Composition/Ingredients

This is the most important section for most nail techs. It lists every ingredient by its chemical name, CAS number (a unique identifier for each substance), and concentration percentage.

This is where you'd check for things like HEMA, MMA, specific photoinitiators, or any ingredient a client has flagged as a concern. Don't be put off by the chemical names — most have common names in brackets alongside them.

A few things to know about reading ingredient lists:

• Ingredients listed as '0–10%' or similar ranges are present but in variable amounts depending on the colour or variant
• 'May contain' entries are typically colourants that differ between shades
• A short ingredient list isn't automatically better — it just means fewer components

 

Section 3 — Hazards Identification

This section describes the potential health and physical hazards of the product. This is where you'll see things like 'may cause skin sensitisation' or 'harmful if inhaled in large quantities.'

It's important to read this in context. SDS documents are written to cover worst-case, industrial-scale scenarios. When you see 'skin sensitiser,' that's a real and relevant warning — but 'may be harmful if large quantities are inhaled' refers to industrial exposure levels, not your salon environment with normal ventilation.

The hazard information here should inform your standard precautions, not cause panic.

 

Section 7 — Handling and Storage

This section tells you how to store the product safely — temperature ranges, light exposure, keeping containers sealed. Practically, this means:

• Keep products away from direct sunlight and heat sources
• Store in a cool, dry place
• Keep lids tightly closed when not in use
• Don't store near open flames (relevant for acetone and some primers)

This section is also where you'd find guidance on ventilation requirements. Good airflow is important in any nail salon — not because your products are acutely dangerous at salon scale, but because long-term exposure to any chemical environment matters for your health.

 

Section 8 — Exposure Controls and Personal Protection

This outlines recommended PPE (personal protective equipment). You'll often see recommendations for respirators, chemical-resistant gloves, and eye protection — again written for industrial contexts.

For salon use, the practical takeaways are:

• Nitrile gloves are worth wearing, particularly during application and removal
• A well-ventilated space is your most important protective measure
• Eye protection is sensible if you're regularly working with liquids like primer or acetone

 

Section 11 — Toxicological Information

This gets into the detail of how each ingredient can affect the body — through skin contact, inhalation, or ingestion. For most professional nail products this section reinforces what Section 3 flags: the main risks are skin sensitisation from repeated contact with undercured product, and respiratory irritation from poor ventilation over time.

If a client reports a reaction and you want to understand which ingredient might be responsible, this is the section to look at alongside Section 2.

 

Section 13 — Disposal

Small amounts of cured gel can typically go into regular waste. Undercured product and liquid chemicals need to be disposed of as chemical waste — don't pour them down the drain. Your local council can advise on chemical waste disposal options in your area.

 

Keeping Your SDS Documents Compliant

Under Australian WHS regulations, you are required to:

• Have a current SDS for every hazardous chemical you use or store
• Make them readily accessible to anyone working with those products
• Keep them for at least 5 years

In practice, the simplest approach is a folder — physical or digital — with one SDS per product. Some techs keep them in a folder on their phone for easy access during client consultations.

If you purchase from Planet Nails, you can download the SDS for every product directly from our website via the SDS tab in the top menu. If you ever can't find an SDS for a product you're using, that's worth questioning — reputable suppliers always have them available.

 

Putting It in Perspective

An SDS is not a reason to be afraid of your products. It's a tool for understanding them. The nail technicians who know their products inside and out — what's in them, how to handle them safely, and what to watch for — are the ones who build long careers without sensitisation issues, and who earn the trust of informed clients.
