Polyglycerol Cosmetics: Natural & Renewable<\/h3>\nPolyglycerol Cosmetics: Natural & Renewable<\/h3>\nSustainable, 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\u00a0Polyglycerol Cosmetics.<\/p>\n
Naturally, emulsifiers, stabilisers and texturisers should also meet these expectations, because even natural cosmetic products cannot do without them.<\/p>\n
<\/p>\n
PEG and PPG are used in cosmetics as well as in the pharmaceutical and food industries as humectants, texturisers and emulsifiers. As emulsifiers, they ensure that substances that are actually immiscible, such as water and oil, can be mixed together. They enable the production of a wide variety of textures with the desired sensory characteristics.<\/p>\n
The widely used PEG\/PPG emulsifiers cover practically all existing HLB ranges.<\/p>\n
Since they are produced synthetically, they are always available, inexpensive and have a long shelf life.<\/p>\n
<\/p>\n
Even though they are well tolerated by the skin and pose no risk in the intended concentrations, PEG\/PPG have come under criticism in cosmetics and have been classified as “questionable” in some cases. PEG-free is now an argument that lifts a product’s image.<\/p>\n
<\/p>\n
The accusations:<\/strong><\/p>\n PEG\/PPG are suspected of making the skin more permeable to harmful, allergenic and carcinogenic substances.<\/p>\n Emulsifiers containing PEG\/PPG, especially in leave-on products, can damage the skin barrier, causing the skin to dry out and be more likely to absorb pollutants and environmental toxins. PEG permeation through intact skin is low, but possible if the barrier is weakened. Synthetic emulsifiers in particular may wash out the skin’s own lipids during cleansing.<\/p>\n There are indications that various synthetic PEGs increase the skin’s sensitivity to light.<\/p>\n PEG\/PPGs are not biodegradable and are therefore harmful to the environment.<\/p>\n Facts about individual PEG\/PPGs cannot be generalised, but nevertheless<\/strong><\/p>\n PEG\/PPG are not desirable in formulations made from renewable raw materials.<\/strong><\/p>\n <\/p>\n The PEG\/PPG-free alternative of polyglycerol cosmetics is of plant origin.<\/p>\n Emulsifiers made from renewable raw materials offer comparable advantages to PEG\/PPG products without their disadvantages, and many are suitable for reformulation into PEG-free products.<\/p>\n Conventional emulsifiers usually contain PEG\/PPG groups as the hydrophilic part.<\/p>\n Polyglycerol cosmetics use a vegetable fatty acid as the lipophilic part and a polyglycerol as the hydrophilic part.<\/p>\n The esters of polyglycerol, made from glycerol and fatty acids of vegetable origin, such as rapeseed or soybean oil, are used as emulsifiers in the food industry.<\/p>\n Polyglycerol cosmetics use renewable raw materials, such as rapeseed oil and RSPO-certified palm kernel oil.<\/p>\n <\/p>\n Compared to ethoxylates (PEG, PPG), polyglycerol esters have the following advantages:<\/strong><\/p>\n <\/p>\n The vegetable polyglycerol esters enable stable emulsions with good skin feel and moisturising properties, adapted viscosity, microbiological stability and are suitable for reformulating PEG\/PPG products with similar skin feel and sensory properties as PEG\/PPG containing O\/W emulsifiers.<\/p>\n They are suitable for the production of O\/W emulsions (sprays, lotions, creams, butters) with good shelf life, in many product and application forms. Polyglycerol cosmetics emulsifiers stabilise emulsions even against challenging ingredients, such as UV filters, critical active ingredients, electrolyte-containing formulations.<\/p>\n Polyglycerol cosmetics often achieve the desired viscosity and stability with the polyglycerol emulsifier alone. The reduced production time, as no additional polyacrylate-containing thickeners, consistency improvers are used, as well as possible hot\/cold processes provide significant energy savings.<\/p>\n <\/p>\n <\/p>\n INCI: Polyglyceryl-3 Distearate; Glyceryl Stearate Citrate.<\/strong><\/p>\n Natural emulsifier with good cost-benefit ratio<\/p>\n Easy to handle, pelletised product<\/p>\n Made from renewable raw materials<\/p>\n np =1.0*, Ino = 1.0*<\/p>\n Easily biodegradable<\/p>\n Vegan**<\/p>\n HLB value: ~ 11<\/p>\n Benefits:<\/strong><\/p>\n Robust stabilising performance for medium to high viscosities<\/p>\n Suitable for all types of cosmetic O\/W creams and lotions<\/p>\n Meets the requirements for formulating natural-based systems<\/p>\n Suitable for formulations using organic acids as “natural” preservatives (pH 4.5 – 5.5)<\/p>\n Can form stable o\/w creams and lotions without the need for polyacrylate-based thickeners.<\/p>\n Can generally be used for emulsions at pH 3.5 – 8.5.<\/p>\n Nourishing, light skin feel and flexible absorption profile.<\/p>\n Ideal for reformulating\/reformulating PEG\/PPG products:<\/p>\n Similar in skin feel and sensory properties to known PEG-containing O\/W emulsifiers, e.g.,\u00a0Glyceryl Stearate; PEG-100 Stearate<\/p>\n <\/p>\n INCI: Polyglyceryl-3 Methylglucose Distearate<\/strong><\/p>\n Universal O\/W emulsifier for lotions, creams, and butter<\/p>\n From renewable raw materials<\/p>\n np = 0.98*, Ino = 0.98*<\/p>\n Easily biodegradable<\/p>\n Vegan**<\/p>\n HLB value: ~ 12<\/p>\n Benefits<\/strong><\/p>\n High stabilising performance for medium to high viscosity (lotion, cream, butter)<\/p>\n Suitable for all types of cosmetic oils<\/p>\n Moisturising properties, supports water resistance<\/p>\n High compatibility with active ingredients, electrolytes and critical actives<\/p>\n Stable emulsions at pH 4.5 up to 8.5<\/p>\n Heat and freeze stable emulsions can be formulated.<\/p>\n Neutral to caring skin feel<\/p>\n <\/p>\n INCI: Polyglyceryl-6 Stearate; Polyglyceryl-6 Behenate<\/strong><\/p>\n Versatile natural O\/W emulsifier<\/p>\n From renewable raw materials<\/p>\n np = 1.0*, Ino = 1.0*<\/p>\n Easily biodegradable<\/p>\n Vegan**<\/p>\n HLB value: ~ 13<\/p>\n Benefits<\/strong><\/p>\n Very high stabilising capacity: Stabilises low viscosity and difficult to stabilise emulsions such as sprays or lotions.<\/p>\n Enables the production of O\/W emulsions based on energy-saving hot-cold processes.<\/p>\n Moisturising properties<\/p>\n Excellent formulation flexibility with respect to high levels of water-soluble UV filters or difficult to incorporate ingredients (e.g., insect repellents, natural preservatives, urea, electrolytes)<\/p>\n Wide pH flexibility from 4.0 to 8.5<\/p>\n Light skin feel, flexible sensory profile<\/p>\n *np = renewable fraction of total active ingredients by molecular weight distribution,<\/p>\n Ino = natural origin index ISO 16128<\/p>\n **as defined by the European Vegetarian Union<\/p>\n <\/p>\n Polyglycerol cosmetics meet the consumer demand for natural, sustainably sourced raw materials in cosmetics and can offer an ideal substitute for PEG\/PPG products with polyglycerol derivatives. The PEG\/PPG-free emulsifiers of polyglycerol cosmetics cover a wide HLB range. They offer the advantages of synthetic emulsifiers without their disadvantages and allow the integration of difficult-to-integrate ingredients. In addition to reformulation, polyglycerol cosmetics enable the reformulation of products containing PEG\/PPG. Above all, it scores with the use of renewable raw materials.<\/p>\nPolyglycerol cosmetics have an ideal substitute for PEG\/ PPG products<\/h3>\n
