Sun Care for Yacht and Golf Guests: EU SPF Rules and What "Reef Safe" Really Means

A charter guest on the aft deck and a golfer on the back nine have one thing in common: four hours or more of strong Mediterranean sun. Sun care is the product they reach for most, and it is also one of the most tightly regulated products a yacht or golf club can put in front of a guest.

This guide sets out what the EU rules say, what a label can and cannot claim, and what "reef safe" really means. Every rule links to the official text.

Sun care is a cosmetic, with its own rulebook

In the EU, sunscreen is a cosmetic product under Regulation (EC) No 1223/2009. Like every cosmetic, each sun care product needs an EU Responsible Person, a safety assessment and a CPNP notification before it is placed on the market. Every claim on the label has to be backed by evidence.

On top of that, the Commission set out how sunscreen efficacy should be tested and labelled in Commission Recommendation 2006/647/EC. It is the reference the whole industry labels against.

What the label has to show

The Recommendation groups SPF into four categories, and the category should appear on the label at least as prominently as the number.

SPF measures protection mainly against UVB, the radiation behind sunburn. The Recommendation also asks for UVA protection of at least one third of the labelled SPF, and a critical wavelength of at least 370 nm, so that a product protects across the spectrum and not only against burning.

Higher numbers add less than people think. The Recommendation notes that SPF 15 absorbs about 93% of UVB and SPF 30 about 97%, and that factors above 50 do not substantially increase protection.

Words a sunscreen cannot use

The Recommendation lists claims that should not be made, because no sunscreen filters all UV radiation:

• No 100% protection: not "sunblock", "sunblocker" or "total protection".
• No claim that it never needs reapplying: not "all day prevention".

Instead, sunscreen should carry warnings such as "Do not stay too long in the sun, even while using a sunscreen product", and instructions such as "Re-apply frequently to maintain protection, especially after perspiring, swimming or towelling".

For yachts and golf clubs, that last instruction is the one that matters. Guests swim off the swim platform, towel off, and go back in the sun. Golfers sweat for hours. A product that is right for them is one guests will actually reapply: light, quick to absorb and pleasant on the skin.

How much guests need to apply

SPF is tested at 2 mg of product per square centimetre of skin. The Recommendation translates this into about six teaspoons, roughly 36 grams, for the body of an average adult. Most people apply far less, and protection falls quickly: if the quantity is halved, protection may fall by as much as two thirds.

This is why the format matters on board and on the course. A generous bottle at the swim platform or in the golf cart, and a stick or lip product for the face and lips, gets used. A tiny tube does not.

Water resistance and sweat

"Water resistant" is a claim like any other: it has to be backed by testing with a recognised water immersion method. Even a water resistant product needs reapplying after towelling, so the label still carries the reapplication advice.

For a yacht programme, ask for the test evidence behind any water resistance claim before the product comes aboard. For a golf club, ask the same question about sweat and long wear.

UV filters the EU has tightened

The ingredients that filter UV are listed in Annex VI of the Cosmetics Regulation, with maximum concentrations. These limits change as the science develops. In 2022, Regulation (EU) 2022/1176 set new limits for two common filters:

• Benzophenone-3 (oxybenzone): up to 6% in face, hand and lip products (excluding sprays), and up to 2.2% in body products, including sprays. Products using it as a UV filter must state "Contains Benzophenone-3".
• Octocrylene: up to 9% in propellant sprays and up to 10% in other products.

A formula developed outside the EU is not automatically within these limits. Every sun care formula has to be checked against the current Annex VI before it is notified.

What "reef safe" really means

"Reef safe" has no legal definition in the EU. There is no test, no threshold and no official list of reef safe ingredients.

Outside the EU, some places have acted on specific filters. Hawaii, for example, banned the sale of sunscreens containing oxybenzone or octinoxate from 1 January 2021, unless prescribed. But a ban on two ingredients does not make every other formula safe for reefs, and the wider science is still developing.

In the EU, environmental claims now face stricter rules. Directive (EU) 2024/825, which Member States apply from 27 September 2026, bans generic environmental claims such as "eco-friendly" or "biodegradable" when the trader cannot demonstrate recognised excellent environmental performance, unless the claim is specified clearly on the same medium. A loose "reef safe" on a product sold to guests carries the same risk.

The safer approach is to say exactly what is true and can be proven, and nothing more.

In the Balearic Islands, there is one more check: Law 8/2019 bans products containing microplastics, so every formula is reviewed against it.

On a yacht and on the course

Yachts. Guests swim several times a day, so reapplication is constant. Sun care sits in warm stores for weeks, so the formula's stability has to be tested before production. Owners and charter guests notice texture: a sticky, white sunscreen stays in the cabin.

Golf clubs. Four or more hours on the course, sweat, wind, and exposed neck, ears, hands and lips. Sun care and lip care in the golf cart and at the first tee get used. Sold in the pro shop under the club name, they also become a line members take home.

A checklist before you offer sun care

• Each product has an EU Responsible Person, a safety assessment and a CPNP notification.
• The SPF and its category are on the label, with UVA protection of at least one third of the SPF.
• No "sunblock", "total protection" or "all day" claims.
• Warnings and reapplication instructions are on the label.
• Any water resistance claim has test evidence behind it.
• UV filters are within the current Annex VI limits.
• Environmental wording is specific and provable, or left out.
• For the Balearics, the formula has been checked against the microplastics ban.

Frequently asked questions

Is SPF 50+ always the best choice for guests? Not necessarily. Above SPF 50, protection barely increases. How much guests apply and how often they reapply matters more. For long days on deck or on the course, high or very high protection in a texture guests enjoy using is the practical choice.

Can we call our sunscreen reef safe? There is no EU definition of "reef safe". Under the consumer rules applied from 27 September 2026, generic environmental claims need recognised evidence or a clear, specific explanation. Describe exactly what is true about the formula instead.

Does sun care sold in a pro shop or on board follow different rules? No. Every sun care product placed on the EU market follows the same Cosmetics Regulation and labelling expectations, whether it is offered free or sold to guests.
