What is the shelf life of Ultrasun products? How long can I use a product once it is opened?

In cosmetics shelf life, expiry dates and PAO signs often lead to consumer misunderstandings. Ultrasun would like to issue a statement on this topic:


Shelf life time

The shelf-life time of all Ultrasun products is 36 months from the date of production (in line with the majority of cosmetic products in general). Ultrasun products can be used with full security at least for this time. Longer data (after 36 months) of product efficacy are not yet available as we have relaunched the majority of our formulas in previous years.


Expiry dates and PAO sign

In the EU products with a shelf life of >30 months need to carry the PAO (period after opening) sign indicating the usage period after the first opening oft he product. Ultrasun products have a PAO of 24 months and can be used therefore during 2 years in the total shelf life period of 36 months. Products with a shelf life <30 months need to state the expiry date (EXP) on pack.

Sunscreen stains on textiles? What can I do?

Stains from the organic UV filters in sunscreen are a general problem for the sunscreen industry. They occur regardless of the sunscreen product used (spray, lotion, aerosol) or the brand. The stains are caused by the organic UV filters in the formulas. The oil-soluble UV filters in particular have a yellowish colour, which can adhere to textiles. These filters are however, absolutely necessary, for protection against the entire spectrum of sunlight.


Ultrasun determined in an in-house test that there are fewer yellow discolourations from the high-quality filters that we use than with other filters that we do not use. In addition, our unique lamellar formulations allow us to use fewer UV filters for the same protection, which leads to less discolouration.


Nevertheless, we have prepared the following washing instructions for textiles:


  1. Washing-up liquid as an emergency solution
    The sunscreen should be removed immediately with a towel, without rubbing it in. Washing-up liquid helps remove fat, so it works very well as the first step because the UV filters are oil-soluble. Rub washing-up liquid into the stain and then wash the garment as per the instructions on the care label.
  2. Stain remover spray
    Spray the stain with a special spray for grease and oil stains and then wash the garment.
    Take special care with stain removal salts and bleach: if you soak your garment overnight in them, the colour may fade. Therefore, take care with textiles and other brightly-coloured items that can fade easily in the washing machine.
  3. Use gall soap
    This old home remedy can be used in a similar way to washing-up liquid: First remove any extra sunscreen with a towel and then rub some gall soap into the stain. After briefly soaking the garment, you can then wash it. Stubborn stains should be pre-treated several times with gall soap (wash by hand) before washing the garment in the washing machine.
  4. Citric acid
    Adding citric acid to your wash can help remove sunscreen stains. The temperature of the washing machine should be set to 50-60°C. The machine should only be slightly filled to prevent a “fold pattern”.
