MediceuticsProtecteur Jour SPF 25Ingredients

Chlorphenesin is a popular preservative. It doesn’t provide any skin-related positive effects and is used to prevent bacterial growth inside a product. It’s a weak preservative but works much better with silicones.

Allowed concentration: no more than 0,3% for European Union countries.

AcrylatesC10-30 Alkyl Acrylate Crosspolymer is a synthetic non-toxic gel used mostly for formulation purposes. It helps manufacturers to achieve the necessary texture of the product (it makes the product thicker). It also has sight healing and antistatic activity.

Potassium Sorbate is a preservative that increases the shelf life of the product. It’s a great alternative to parabens. That's why manufacturers like to use this component. It is safe in concentration of up to 10% but it is used in cosmetics in amounts of 1% or even lower.

Sodium Citrate is a water-soluble soft organic surfactant with strong stabilizing and conditioning effects. It helps to produce foam and lowers the negative impact of hard water on your skin and hair. It also helps to regulate the pH level of the product. It’s a natural ingredient and it’s safe for most people. It’s used in food (additive number E331).

Tocopheryl Acetate is a form of Vitamine E. It’s used as an alternative to Tocopherol because it is more stable in the formulation. It has all the positive effects of Tocopherol plus better stability. It’s a brilliant component. It conditions and nourishes the skin helping it to resist aging. It also helps to protect the skin from the sun. High concentrations of Tocopheryl Acetate can lead to irritation and allergic reactions.

Disodium EDTA is an emulsion stabilizer and chelating agent. It deactivates the metal ions preventing them from reacting with other active ingredients. It improves the stability of a cosmetic formula and keeps the product’s consistency, texture, and pH unchanged. It doesn’t have any skincare effects and is used for formulation purposes only.

Phenoxyethanol is one of the most popular preservatives. It kills bacteria and makes the product live longer. Manufacturers like this ingredient because it can dissolve in any liquid, even in oils.

Another purpose of this component is the fixation of aromas in perfumery. Phenoxyethanol is also used as a strong antiseptic and a good antibacterial agent. It is widely used in dermatological cosmetics alongside natural antiseptics such as chamomile, sage, and calendula.

Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.

It can be an irritator due to its naturally lower pH level of 2.2. But manufacturers also use it as a pH adjuster so in most cases you will not have any issues.

BHT is a stabilizer and antioxidant. It helps to keep the product fresh for a long time, preventing the oxidization of components. It is stable even in high temperatures, that’s why it’s an essential component in some products. It also protects the skin from free radicals. As for safety, the component isn't researched very well. It’s considered to be safe in low concentrations. But there is still not enough scientific data collected.
