The synthesised compounds were characterised and confirmed by Fourier Transform–infrared spectroscopy and proton nuclear magnetic resonance spectroscopy. In addition, the physical, biodegradable and dyeing-assisting properties of CPm were evaluated through comparison with tristyrylphenol ethoxylates (A typical commercial surfactant). Results revealed that CPm showed a higher hydroxyl value, better dispersing capability and a higher migration percentage than tristyrylphenol ethoxylates. Specifically, CP5 (0.5 g/L) improved the migration percentage by 12.03% compared with tristyrylphenol ethoxylates. The migration performance of the surfactants followed a descending order of CP5 > CP7 > CP9 > tristyrylphenol ethoxylates. Importantly, CP5 displays a higher degradation propensity than tristyrylphenol ethoxylates, demonstrating its biodegradable merit. In summary, the cardanol-based polyethoxylates synthesised through this research are promising biodegradable and effective alternatives to conventional levelling agents for disperse dyeing, which contributes a new strategy to the sustainable development of the textile industry.

In the personal care industry, there is an ever-increasing demand for milder, naturally derived ingredients that has been driving the selection of raw materials globally. In addition, there remains a focus within the industry to find alternatives to sodium lauryl sulfate, and sodium lauryl ether sulfate.
The reasons for the shift towards sulfate-free mostly arises from reports of skin irritation due to exposure to both of these sulfate based surfactants.1 To facilitate the move to using alternatives to alkyl sulfates and alkyl ether sulfates, Innospec have developed a wide range of chemistries based on both (alkyl) acyl amino acids and acyl (methyl) isethionate chemistries to improve skin mildness in formulations.
The drive towards sulfate-free started over 15 years ago when concerns were raised in an internet blog over the use of alkyl and alkyl ether sulfates in personal care products. Over the past ten years, consumer concern has continued to grow significantly causing market leaders to launch an ever-increasing number of sulfate-free formulations to both the consumer and professional personal care markets. One key thing to remember: economics will never be the driving factor in the journey to develop sulfate-free formulations.Note de contenu : - Importance of formulation pH on selection of mild surfactants

Surfactants -- Suppression ou remplacementIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Surfactants are an indispensable part of people's daily lives as they are used in a wide range of home and personal care applications. They are often used as the core ingredients for cleansing, foaming, emulsifying, solubilizing, and conditioning purposes in personal hygiene applications such as shampoo, body cleanser, make-up removers, or toothpaste.
Short for 'surface-active agents', surfactants are made up of both hydrophilic and lipophilic parts, and this unique molecular composition gives them the ability to reduce surface tension. When surfactants are used in personal cleansing products, the lipophilic end of the surfactant attracts and lifts the dirt on the skin or hair surface, white the hydrophilic end of the surfactant allows the micelle-trapped dirt to be easily rinsed by the water.
While conventional petrochemical-based surfactants serve functional purposes, they present a lower eco profile with common concerns on sustainable sourcing and environmental biodegradation. Furthermore, some of these conventional petrochemical-based surfactants are known to cause irritation to the human body.
In recent years, the global beauty and personal care market has shown a keen interest in surfactants with higher naturality and mildness daims. These natural surfactants are often delivered by biotechnologies from three categories : partially bio-based surfactants, fully bio-based surfactants, and biosurfactants.Note de contenu : - GLYCOLIPIDS : SOPHOROLIPIDS AND RHAMNOLIPIDS : Sophorolipids - the first glycolipids in cosmetics applications - Rhamnolipids - the next generation in cosmetic application
