C'est une molécule chirale car l'atome de carbone 2 portant un hydroxyle est asymétrique. Le pentane-1,2-diol se présente donc sous la forme de deux énantiomères : le R-pentane-1,2-diol et le S-pentane-1,2-diol. Produits hydratants Résistance à l'humidité:Résistance à l'eau Index. décimale : 668.5 Parfums et cosmétiques Résumé : 1,2-Pentanediol (INCI: Pentylene Glycol, trade name: Hydrolite-5) is a widely used cosmetic raw material with multifunctional properties. It is an excellent moisturizing ingredient for topical preparations. Besides it has very good antimicrobial and solubilizing properties. It also improves the water resistance of sunscreen formulations. This paper discusses the studies that exemplify the multifunctional aspects of 1,2-Pentanediol. It also discusses the results of a new study, which looks at the effect of 1,2-Pentanediol on the particle size and particle size distribution of an oil-in-water emulsion. The new study shows that 1,2-Pentanediol is able to significantly reduce the particle size of cosmetic emulsions. Furthermore, sensory studies with emulsions containing 1,2-Pentanediol demonstrated that the appearance and the tactile properties of cosmetic emulsions are also improved by the addition of this multifunctional ingredient.

Changes to surface flaws on deer hides during processing to garment leather / S. E. Gore in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 86, N° 5 (09-10/2002)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 86, N° 5 (09-10/2002) . - p. 183-187 Titre : Changes to surface flaws on deer hides during processing to garment leather Type de document : texte imprimé Auteurs : S.

Langues : Anglais (eng) Catégories : Cuirs et peaux -- Défauts Cuirs et peaux de cerfs Surfaces -- défauts Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The objective of this work was to describe surface flaws and defects visible at each of three stages of processing deer hides to garment leather (fellmongered, wet blue, and finished leather). Hides (n=60) from deer of known origin were examined visually at three stages of production. Visible surface faults were identified and recorded at each of the three stages. Some flaw (a bruise, scar, grain de-lamination, hole) was apparent on almost every hide (95.0% - 100.0% depending on the stage of processing), and with ‘new’ flaws becoming apparent with processing. The most common type of flaw visible in finished leather was the scratch, with many scratches evident at each processing stage. Reducing the incidence of scratches would improve the appearance of the leather. Note de contenu : - METHODS : Deer hides - Recording of flaws - RESULTS AND DISCUSSION : Number of flawed hides (and changes with processing), and flaw location - Types, size, shape of flaws, and changes with processing - Table 1 : Site on hides at which flaws were evident, and incidence of flaws of three processing stages - Table 2 : Incidence of flaw types at each of three processing stages - Table 3 : Size and shape of flaws at various stages of processing (number of observations) En ligne : https://drive.google.com/file/d/1BjQIzqVBtACkjSkPSxHtlJbCjQcEOReA/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=39857 [article]

Deer leather as a material for outerwear / S. Lange in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 86, N° 4 (07-08/2002)

Hides from deer of known origin were processed to finished garment leather and selected properties of the finished leather relevant to garment manufacture were measured. Variability in these properties across any one hide, and among hides from different animals was determined and was less than that reported for ovine leather and similar to that reported for woven textiles used in outerwear. The extension of deer leather exceeded that recommended for woven garment materials, and was greater than that observed on ovine leather. The location on a hide, and the number of hides to be sampled from each batch in order to obtain representative results were determined (near the backbone at approximately the fore leg position ; and three, respectively).

Determining suitability of leather for garments / S. Lange in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 83, N° 1 (01-02/1999)

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 83, N° 1 (01-02/1999) . - p. 1-7 Titre : Determining suitability of leather for garments Type de document : texte imprimé Auteurs : S. Lange, Auteur ; R. M. Laing, Auteur ; B. E. Niven, Auteur Année de publication : 1999 Article en page(s) : p. 1-7 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Garment leather produced from ovine skins is used to manufacture high quality and high cost products. Little is known about which physical properties of this leather affect the garment construction processes and which physical properties are relevant to end-use performance. Test methods developed to assess suitability of woven materials for use in tailored garments were applied to lightweight garment leather from four breeds of sheep (male and female), but subjected to identical processing conditions. Specimens were cut from different locations and orientations on the skins. Location and orientation had a more significant effect on properties than the biological factors of breed and sex. Tanners can use these methods to develop leather with characteristics suitable for garment manufacturing processes.

Specimen site and number of skins required to represent selected physical properties of ovine garment leather / S. Lange in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 84, N° 3 (05-06/2000)

Langues : Anglais (eng) Catégories : Cuirs et peaux -- Propriétés physiques Cuirs et peaux de moutons Echantillonnage Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Properties critical in the manufacture of garments from textile materials were measured on 158 ovine skins typical of those used in garment manufacture, and the location from which properties of leather most represent those of the whole skin identified. Mass, thickness, compression, bending and extension under low loads (lOOgf/cm) were measured at between four and eight locations either side of the spine, and two directions (0 and 90° to the spine) on each skin. The most representative location was adjacent to the spine and in the middle of the skin, and was similar to but larger than that recommended in existing standard test methods for leather. Approximately 10 skins were required to estimate the properties of a batch of ovine garment leather.
