Ingredient

POLOXAMER 338/PPG-51/SMDI COPOLYMER

Substance information

Poloxamers are block copolymers composed of ethylene oxide and propylene oxide. With the suffixed number the mass percentages of the two components as well as the overall molecular mass are encoded. "PPG" refers to a PPG-(polypropylene glycol-) derivative. The number behind "PPG-" (in the event of mixed PEG/PPG derivatives, the second number) states the average number of molecular units -CH2-CH2-CH2-O-. Polymer or copolymer based on methylenedicyclohexyl isocyanate (SMDI) and possibly other monomers. "Copolymer" refers to a polymer composed of several different (mostly two) basic units (monomers).

Background information on use in cosmetics

Polypropylene glycol (PPGs) and their derivatives are used in cosmetic products like the polyethylene glycols (PEGs). They are often used in cosmetic products since they have a broad range of viscosity and solubility properties and have a very good skin tolerance. As water soluble, non-greasy substances, polypropylene glycols are suited for many cosmetic purposes. The liquid PPGs serve, for instance, as solubilizers and solvents.

Regulating cosmetics

Cosmetics Ingredients are subject to regulation. Please note, different regulations may apply to cosmetic ingredients outside the EU.

Understanding your cosmetics

How are cosmetics kept safe in Europe?

Strict laws make sure that cosmetics and personal care products sold in the European Union are safe for people to use. Companies, national and European regulatory authorities share the responsibility of keeping cosmetic products safe.

What should I know about endocrine disruptors?

Some ingredients used in cosmetic products have been claimed to be ‘endocrine disruptors’ because they have the potential to mimic some of the properties of our hormones. Just because something has the potential to mimic a hormone does not mean it will disrupt our endocrine system. Many substances, including natural ones, mimic hormones but very few, and these are mostly potent medicines, have ever been shown to cause disruption of the endocrine system. The rigorous product safety assessments by qualified, scientific experts that companies are legally obliged to carry out cover all potential risks, including potential endocrine disruption.

Are cosmetics tested on animals? No!

In the European Union, testing cosmetics on animals has been fully banned since 2013. Over the last 30 years, long before a ban was in place, the cosmetics and personal care industry has invested in research and development to pioneer alternatives to animal testing tools to assess the safety of cosmetics ingredients and products.

What about allergens in cosmetics?

Many substances, natural or man-made, have the potential to cause an allergic reaction. An allergic reaction occurs when a person’s immune system reacts to substances that are harmless to most people. A substance that causes an allergic reaction is called an allergen. Cosmetics and personal care products may contain ingredients that can be allergenic for some people. This does not mean that the product is not safe for others to use.

Database

Cosmetics matter to people and play an important role in our everyday life. On average European consumers use over seven different cosmetics daily. You too? It’s only natural that you want to know more about the ingredients in those products.

In the digital world we live in, there’s a deluge of information on cosmetics. However, it can be difficult to know which sources are reliable. COSMILE Europe is a European cosmetic ingredient database that offers reliable, verified and scientifically supported information on almost 30,000 ingredients used in cosmetics.

This database will help you understand why certain ingredients are in your cosmetic products; which properties they have and much more. The database is currently available in fourteen languages with more to come.
