Enhanced foaming properties and mildness on skin / Victor Low in PERSONAL CARE EUROPE, Vol. 12, N° 2 (04/2018)  

[article]  inPERSONAL CARE EUROPE > Vol. 12, N° 2 (04/2018) . - p. 49-52 Titre : Enhanced foaming properties and mildness on skin Type de document : texte imprimé Auteurs : Victor Low, Auteur Année de publication : 2018 Article en page(s) : p. 49-52 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Essais (technologie) Ether de polyglycidyle Formulation (Génie chimique) Moussants Peau -- Soins et hygiène Surfactants Tests cutanés Index. décimale : 668.5 Parfums et cosmétiques Résumé : Polyaldo 10-1-CC mild surfactant delivers the best of both worlds. It offers an excellent irritation profile, with mildness on a par with PEG-80 sorbitan laurate, combined with the initial flash foaming speed of decyl glucoside, a moderate to severe irritant (based on our study). Polyaldo 10-1-CC mild surfactant builds foam structure faster than PEG-80 sorbitan laurate, and creates a more stable foam structure and creamier foam. It has higher surface activity than PEG-80 sorbitan laurate, resulting in efficacious cleansing and a better cost-performance ratio. Classified as very low-irritating, it is a gentle surfactant for skin and hair applications where mildness is needed. In addition, Polyaldo 10-1-CC mild surfactant mitigates surfactant penetration into the stratum corneum, protecting skin from potential damage caused by harsh surfactants and maintaining the stratum corneum moisture balance.

Hydrolyzed proteins for anti-pollution hair care / Saso Efremovski in GLOBAL PERSONAL CARE, Vol. 24, N° 6 (06/2023)  

[article]  inGLOBAL PERSONAL CARE > Vol. 24, N° 6 (06/2023) . - p. 53-57 Titre : Hydrolyzed proteins for anti-pollution hair care Type de document : texte imprimé Auteurs : Saso Efremovski, Auteur ; Vanessa Mai, Auteur ; Andrea Serrano Trujillo, Auteur ; Victor Low, Auteur Année de publication : 2023 Article en page(s) : p. 53-57 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Actifs anti-pollution Antioxydants Brillance (optique) Cheveux -- Soins et hygiène Hydratation Hydrolyse Protéines végétales Index. décimale : 668.5 Parfums et cosmétiques Résumé : Pollution and UV radiation from the sun are two of the primary causes of damaged hair follicles and lead to a significant impact on appearance. Novel technologies, which consist of hydrolyzed rice protein, Adansonia digitata seed extract, and Amaranthus caudatus seed extract, was specifically designed to overcome pollution in hair and to increase shine and moisturization of hair fibres damaged from UV radiation. Findings show that through SEM/EDS analysis, these hydrolyzed proteins significantly shield from external pollutants of calcium and aluminum in virgin Chinese and Indian hair fibres. Hair moisturization, measured by water vaporization content, was increased by 24.15 % and visible improvement in shine was observed by 9.18 % of the UV damaged, Caucasian hair fibres after application.

A naturally derived polyglyceryl ester : The best of both worlds / Victor Low in SOFW JOURNAL, Vol. 143, N° 10 (10/2017)

The demand for "natural" chemistries further drives up the need for alternative surfactant technologies. To meet these demands, we have created a non-ionic surfactant called Polyaldo 10-1-CC polyglyceryl ester based on our polyglyceryl ester technology. This naturally-derived polyglyceryl ester offers the best of both worlds : improved quality of foam whist exhibiting a very low irritation profile. The following article compares the foaming properties, surfactancy attributes, and irritation profile of Polyaldo 10-1-CC polyglyceryl ester aqainst typically established surfactants found in the marketplace. Foam studies were performed with the recently launched KRUSS RMFA, the first instrument for fully analysis according to the Ross-Miles standard. The performance results show Polyaldo 10-1-CC polyglyceryl ester is a highly performing surfactant with great foaming and a very low irritation profile on skin.
