By 2025, two-thirds of the world’s population may be at risk of water scarcity. Each person directly consumes around 140 litres/day of water, 40% of it in the bathroom. The Energy Saving Trust reports that the greatest opportunities for saving water can be found in the bathroom, with showering being the largest water user in the home. Water scarcity is a global issue that is now being reflected in consumers’ choices. Conscious consumer behavior is helping to support this market development. Studies suggest that 22% of UK consumers have changed their bathroom routine to use less water, while 34% of Italian consumers are interested in double concentrated bath or shower products. Personal care products that require less or even no water are becoming more popular. Avoiding a daily shower with no-rinse products is an option consumer are considering. Thus, 45% of US soap, bath, and shower users stated that they would be interested in no-rinse products. Norinse formulations can be used without the need for water. The product is simply left in the hair and rinsed off later. These formulations can also absorb any excess oils. For similar reasons, dry shampoo product launches have been increasing in the last five years, driven by consumer demand and this is not limited to hair styling products. Dry shampoos have traditionally been used to provide the extra volume required for special occasions. Most consumers will be familiar with their drawbacks, however. The high powder content of these products causes itchiness and leaves the scalp feeling dry. They can also be inconvenient, requiring additional brushing to remove the excess powder. When convenience and comfort are sacrificed, consumers are left feeling uncomfortable and selfconscious. Avoiding water consumption is only part of the issue. Products still need to perform. Real behavioural change that will last a lifetime will only happen if this is the case. Spherelix 10® (INCI : Hydrated Silica), hereafter referred to as spherical hydrated silica, is a key ingredient that Evonik supplies for use in dry shampoos. It improves their performance, making daily use possible without the disadvantages traditionally associated with dry shampoo.

Pickering emulsions stabilised via novel fumed silica / Heike Riedemann in PERSONAL CARE EUROPE, Vol. 12, N° 1 (02/2018)  

[article]  inPERSONAL CARE EUROPE > Vol. 12, N° 1 (02/2018) . - p. 76-79 Titre : Pickering emulsions stabilised via novel fumed silica Type de document : texte imprimé Auteurs : Heike Riedemann, Auteur ; Jörg Münzenberg, Auteur Année de publication : 2018 Article en page(s) : p. 76-79 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Emulsions -- Emploi en cosmétologie Emulsions -- Stabilité Emulsions pickering Silice La silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux. La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...). Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale. Index. décimale : 668.5 Parfums et cosmétiques Résumé : The stabilisation of emulsions by particles typically referred to as Pickering emulsions is a thoroughly investigated alternative to the use of organic emulsifiers. Fumed silica (INCI: Silica, Silica...Silylate) has a long track record in personal care formulations. A novel type of these traditional ingredients has been modified in a way to have both hydrophilic and hydrophobic properties in the same particle. This special feature makes the material that is available as Aerosil R 816 (INCI: Silica Cetyl Silylate) resemble organic emulsifiers. The material has been tested for its ability to stabilise O/W emulsions. Remarkable stable emulsions have been obtained with a wide range of emollients and oil concentration using only a small dosage of the novel Pickering Stabiliser. The stabilisation of emulsions with Aerosil R 816 as well as its effect on other properties of the emulsions have been investigated.
