These operations remove hair and flesh, degrease the fat, open the structure, modify the collagen, and lower the pH in preparation for conventional tannage. A critical part of the beamhouse operation is the removal of the alkali added during theliming/unhairing operation. After the liming/unhairing the pelt is full of large quantities of calcium, sodium and hydroxyl ions (either as hydroxides of the metals or as separate species). The deliming chemical must be able to bind to the divalent metals or to neutralise the hydroxyl as an acid.

High-performance sulphate-free cleansers : Surface activity, foaming and rheology / Kelly Yorke in INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Vol. 43, N° 6 (12/2021)  

[article]  inINTERNATIONAL JOURNAL OF COSMETIC SCIENCE > Vol. 43, N° 6 (12/2021) . - p. 636-652 Titre : High-performance sulphate-free cleansers : Surface activity, foaming and rheology Type de document : document électronique Auteurs : Kelly Yorke, Auteur ; Andrei Potanin, Auteur ; Suzanne Jogun, Auteur ; Andre Morgan, Auteur ; Hongwei Shen, Auteur ; Samiul Amin, Auteur Année de publication : 2021 Article en page(s) : p. 636-652 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Alkyl oléfine sulfonate Alkyl polyglycosides Moussage (chimie) Produits nettoyants Rhéologie Rhéomètres Sulfates -- Suppression ou remplacement Surfactants Tension superficielle Viscoélasticité Index. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : The main objective of this paper is to analyse the composition of a sulphate-free binary or ternary surfactant system with alkyl olefin sulfonate (AOS), alkyl polyglucoside (APG) and lauryl hydroxysultaine (Sultaine). The composition was optimized by observing critical parameters such as surface activity and rheological properties while varying the concentration of APG in a ternary system, varying the ratio of AOS and Sultaine in a binary system and studying the effect of sodium chloride addition. The experimental results can provide an alternative, sulphate-free surfactant system to replace the common system containing sodium laureth sulfate (SLES) and cocamidopropyl betaine (CapB), without compromising on the parameters previously mentioned. - Methods : A DuNouy Ring was utilized on a tensiometer to measure the surface tension of the samples. To observe foaming abilities of samples, a visual foaming study was conducted and recorded by taking pictures. A TA instruments mechanical rheometer was used to measure the viscosity. - Results : Studying the effect of APG concentration on surface tension illustrated that as APG concentration decreases, surface tension decreases as well. The minimum surface tension was found to be 26.587 for 7.5 wt.% AOS and 7.5 wt.% Sultaine. When the ratio between AOS and Sultaine changed, the 1:1 system produced the lowest surface tension value again. As the concentration of AOS decreased in the ratio, the surface tension increased. When the ratio was held constant, and APG was introduced into the system, the systems containing APG had higher surface tension values compared with the systems with the same ratios but did not have APG added. As the concentration of salt increased, the surface tension decreased for AOS, increased for the binary mixture and had no effect on Sultaine. Foaming has a direct correlation with surface tension so a decrease in surface tension led to better foaming abilities; therefore, the 1:1 ratio of AOS:Sultaine had the best foaming qualities. The AOS/Sultaine system exhibited Maxwellian behaviour, suggesting the presence of worm-like micellar structures. As the concentration of APG increased, the viscosity decreased and at a concentration of 2.5 wt.% AOS, 5 wt.% APG and 7.5 wt.% Sultaine, the system changed from shear thinning non-Newtonian fluid to Newtonian. Varying the ratio of AOS:Sultaine in the binary system, showed as the ratio changed, the viscosity decreased, and at a ratio of 1:3 AOS:Sultaine, the system was primarily Newtonian. As the ratio remained constant and APG was added, the viscosity continued to decrease and the 1:3 ratio was completely Newtonian. The addition of salt had no effect on the viscosity of Sultaine, but the viscosity of AOS increased at a salt concentration of 2 wt.%. The binary mixture saw as the concentration of salt increased, the viscosity profile decreased, even though the system remained non-Newtonian and shear thinning. - Conclusion : The surface activity and rheological study of the sulfate-free surfactant systems unveil a strong synergistic interaction between AOS and Sultaine specifically at a ratio of 1:1 resulting in high surface activity and corresponding good foaming and formation of entangled wormlike micelles resulting in excellent viscosity build in the system. If introducing a biobased surfactant into this system is desired without completely compromising the performance properties, the ternary surfactant system 4.5 wt.% AOS, 3 wt.% APG and 7.5 wt.% Sultaine should be considered optimal. Any further addition of APG or changing the ratio results in detrimental reductions of all performance controlling physio-chemical parameters.

Mild cleansers with 'sulfate-free' surfactants / Peter Clark in GLOBAL PERSONAL CARE, Vol. 23, N° 10 (11/2022)  

[article]  inGLOBAL PERSONAL CARE > Vol. 23, N° 10 (11/2022) . - p. 55-58 Titre : Mild cleansers with 'sulfate-free' surfactants Type de document : texte imprimé Auteurs : Peter Clark, Auteur ; Alice Miles, Auteur ; Jeannie Ang, Auteur ; Steve O'Connor, Auteur ; Russell Cox, Auteur Année de publication : 2022 Article en page(s) : p. 55-58 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dermo-cosmétologie Douceur (toucher) Formulation (Génie chimique) Hygiène Peau -- Soins et hygiène Produits nettoyants Sulfates -- Suppression ou remplacement Surfactants -- Suppression ou remplacement Index. décimale : 668.5 Parfums et cosmétiques Résumé : Innospec Performance Chemicals has developed a wide range of chemistries based on both (alkyl) acyl amino acids and acyl (methyl) isethionate chemistries to improve skin mildness in formulations. 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.
