Plant polyphenols: powerful protective substances for healthy skin
Plant polyphenols are much more than just secondary plant substances: they are true all-rounders of nature and a valuable treasure for modern skin care. These bioactive compounds protect plants from harmful environmental influences, microorganisms and UV radiation. They are playing an increasingly important role in cosmetic products due to their antioxidant and anti-inflammatory properties. But…
Plant protection products
Plant protection products, which are often simply abbreviated to PPPs, can generally be divided into different categories. Fungicides, for example, are biological or chemical agents that kill fungi or their spores or inhibit growth. Herbicides are basically nothing more than weedkillers; they are intended to kill off troublesome plants as quickly and effectively as possible.…
plant-based cosmetics
In January 2015, an estimate by the Vegetarierbund Deutschland (German Vegetarian Association) showed that there are about 900,000 vegans living in this country. For these people, veganism represents a way of life and philosophy. The motivations are the same for almost all vegans: according to the Vegan Society’s 1979 memorandum, “all forms of exploitation as…
Plasma technology
Physics actually recognises three states of matter: solid, liquid and gaseous. If, however, further energy is added to a gas, plasma is created – the often forgotten fourth state of matter. Plasma technology results from this state of aggregation. The term comes from the Greek word plásma (translated: structure) and was first used by the…
Plastics
A wide variety of plastics are used for cosmetic packaging, increasingly replacing glass. Whereas plastics were previously only used for packaging components such as closures, caps, stoppers and seals, their use has rapidly expanded in recent years to include the manufacture of complete primary packaging in the form of bottles, bags, jars, sachets and even…
Polyacetylenes – bioactive compounds with potential
Polyacetylenes are an exciting class of organic compounds characterised by multiple C≡C triple bonds. Although they appear unstable in their pure form, they exhibit remarkable stability when bound in plants, fungi or marine organisms. It is precisely this balance of reactivity and stability that makes these polymers highly interesting molecules for cosmetic research and application.…
Polyethylene glycol – versatile, inexpensive, but problematic
Polyethylene glycol is a synthetic raw material that has been used in countless formulations in the cosmetics industry for decades. The special feature of polyethylene glycol is its extreme versatility. Depending on its chain length and structure, the substance can take on a wide variety of properties: sometimes liquid, sometimes paste-like, sometimes solid. It is…
Polyglucosamine
Polyglucosamine is a naturally occurring polyaminosaccharide also called poliglusam, poly-D-glucosamine or chitosan. The term is derived from the Greek description for undergarment, covering or armor. Polyglucosamine is derived from chitin, and the substance was first obtained in 1859 by Charles Marie Benjamin Rouget, a French physiologist and histologist, by boiling with potassium hydroxide solution. It…
Polyglutamic acid
Polyglutamic acid is a biopolymer that occurs naturally in various organisms. For example, it is synthesised by archaea, bacteria, and cnidarians (coelenterates). These organisms use polyglutamic acid as an adhesive and a slimy protective layer. It is also a main ingredient of natto, the traditional Japanese food made from soybeans. In the process, the cooked…
Polyglycerol Cosmetics
Polyglycerol Cosmetics: Natural & Renewable Sustainable, natural, made from renewable raw materials, vegan, free of – these are properties for cosmetic products that are increasingly demanded by consumers and fits perfect to Polyglycerol Cosmetics. Naturally, emulsifiers, stabilisers and texturisers should also meet these expectations, because even natural cosmetic products cannot do without them. PEG/PPG emulsifiers…
