TexturantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The use of cosmetics is connected to soul and body; with an increasing desire for sustainability. As an answer, several types of estolides were synthetized by ingredient manufacturers, starting from vegetable fatty acids. Two main ways of synthesis of these intermolecular esters can be considered, depending on the raw materials.
We developed a new estolide ester, based on castor oil, engineered with as few transformations as possible, showing a great versatility in applications for cosmetic formulators, and a high degree of Naturality. The performances of this innovative polymer ingredient, dedicated to haircare, skincare, and lipcare, were screened through a sensorial panel and instruments.
Our estolide ester brings a broad range of properties as texturizing or film-forming agent, and moisturizer. It also shows interesting values as a pigment disperser. During application on hairs, skin, or lips, this ester of estolide will give high protective properties from air pollution.
The ingredient we tuned showed to be fully biodegradable, and its NOI (Natural Origin Index) is 87%.
Our commitment to Naturality determined our scientific approach, and our technology allowed us to manufacture this ester of estolide with unique performances and a reduced environmental footprint.Note de contenu : - General ideas about estolides

OdeursIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - OBJECTIVE : Fatty esters are known for their versatility, but in addition to their performance as emollients, emulsifiers, solubilizers, or dispersing agents, they have to meet more and more criteria to be used in cosmetic products. Thus, their olfactory characteristics are expected to be as neutral as possible. However, despite a step of deodorization during the synthesis of fatty esters, a residual odour is currently still perceived at the end of the process.
- METHODS : In this study, a specific analytical methodology combining sensory with chemical analyses was implemented to characterize the residual odour of two fatty esters and to determine its origin. Ethyl oleate and isononyl isononanoate were selected and underwent a sensory analysis to evaluate their odour intensity and odour profile. Volatile compounds released by these esters were assessed by GC–MS after solid-phase microextraction and among them, odouractive compounds were brought into light using gas chromatography coupled with mass spectrometry and olfactometry analyses.
- RESULTS : On the isononyl isononanoate chromatogram, only peaks corresponding to the different isomeric ester forms were evidenced while around 70 volatile compounds were detected in the ethyl oleate headspace, including esters, aldehydes, hydrocarbons, and ketones. Isononyl alcohol used as raw material in the synthesis was proven to be responsible for isononyl isononanoate final odour. As for ethyl oleate, of the 23 odour-active compounds perceived, 14 have been identified; they are mainly esters and saturated as well as unsaturated aldehydes.
- CONCLUSION : A novel measurement approach was presented to analyse trace odours of fatty esters and the results will be useful to control their deodorization by targeting appropriate strategies with the aim to either avoid the formation or remove the identified odorant compounds. This study may be further expanded by investigating the impact of deodorization on odour-active compounds for a complete understanding of their contribution to the fatty ester global odour.Note de contenu : - MATERIALS AND METHODS : Samples - Sensory analysis - Analysis of volatile compounds by SPME-GC–MS - Analysis of odorant compounds by GC–MS-O - Quantification of isononyl alcohol and 3,5,5-trimethylhexanoic acid traces in isononyl isononanoate samples by GC-FID
