RugositéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Since skin on the lips has a lower water content in the stratum corneum (SC) and a higher transepidermal water loss (TEWL) value than skin on the cheek, the lips are usually very dry and rough areas. Therefore, a lip balm approach to increase occlusivity of the lips is generally used to reduce water loss. Although there have been reports of an improvement effect on lip roughness by specific care agents, differences in the effects due to the occlusivity of a formulation without a specific care agent have not been reported. The purpose of this study was to clarify the improvement effect on dryness and roughness of the lips by a highly occlusive formulation consisting of a combination of common oil and wax, not by a specific care agent.
- Methods : Twenty Japanese female subjects with normal skin (age range 20-39 years; mean 28.1) were enrolled in this study. A 4-week continuous use test was conducted using samples with low and high occlusivity. The degree of lip roughness and wrinkles was scored, the hollow index was assessed using ANTERA 3D images, and values of capacitance and TEWL were measured.
- Results : The hollow index was significantly correlated with both the appearance roughness score and the wrinkle score. The sample with high occlusivity showed significant improvement in the appearance roughness score, wrinkle score, the hollow index and capacitance of the SC. In a comparison between the groups of samples with different occlusive properties, a significant improvement effect in rough appearance was seen in subjects using the highly occlusive formulation.
- Conclusion : The hollow index assessed by ANTERA 3D imaging allowed the objective evaluation of the improvement in appearance. In the case of continuous use of the highly occlusive formulation, an improvement of capacitance in the SC, which is most correlated with lip roughness, was obtained after 2 and 4 weeks. These results demonstrate for the first time that a highly occlusive formulation is effective in improving the roughness of the lips, and this effect is due to the difference in the occlusive property not by a specific care agent.Note de contenu : - MATERIALS AND METHODS : Ethics - Subjects - Materials - Measurment of occulisivity - Biophysical measurements of the SC - Degree of lip roughness and wrinkles - ANTERA 3D image analysis - Statistical analysis

Température de retraitIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Montmorillonite (MMT) has been modified with a long chain quaternary ammonium salt through a cation exchange reaction. The extent of the exchange was characterised by XRD (X-ray Diffraction), FT-IR (Fourier Transform Infrared Spectroscopy) and by the determination of CEC (Cation Exchange Capacity).The results prove that alkylammonium ions have taken the place of Na+ ions in Na+ - Montmorillonite (Na-MMT) and that the inter-laminar distance has been enlarged.
The possibility of using Na-MMT and organic-montmorillonite (O-MMT) in the treatment of wastewater from tanneries by utilizing their adsorption properties has been studied. The result shows that Na-MMT and O-MMT can absorb fatliquors to a certain extent.
A series of tanning experiments have been carried out to compare the tanning properties of Na-MMT, O-MMT and O-MMT/Cr3+. The results suggest that Na-MMT and O-MMT have some tanning capability, and that the composite O-MMT/Cr3+ with a very low content of Cr3+ can produce leather of light colour with a shrinkage temperature above 90oC.Note de contenu : - EXPERIMENTAL PROCEDURE :

Pâteux (ingrédients cosmétiques)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Natural oils have become a common additive to personal care products. They fit the definition of natural, sustainable and can be renewable and even organic. While these classifications are sometimes unclear in meaning, the reason we formulate with a particular oil is often just as obscure. Is it marketing, or carbon distribution or aesthetics or perhaps a particular benefit rendered to the oil by a particular native material (antioxidants, UV absorbers) ? This article will look at some of these properties. Note de contenu : - Definitions

TriglycéridesIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, Poly(styrene-co-chloromethyl styrene) [Poly(St-co-CMS)] was prepared and used in the modification of triglyceride oils. The obtained modified triglyceride product was examined in view of oil-based binder. Nitroxide-mediated radical polymerization (NMRP) technique was applied for Poly(St-co-CMS) synthesis. Chloro groups on the Poly(St-co-CMS) backbone were reacted with 2-amino-1-butanol (2-AB) in order to obtain a polymer with hydroxyl ended side branches, [Poly(St—OH)], which were further combined with partial glycerides (PGs) through the reaction with toluene diisocyanate (TDI). The resulting product can also be considered as a polystyrene-modified urethane oil [Poly(St-OH)-SUO]. The structures of both intermediates, [Poly(St-co-CMS), Poly(St—OH)], and final products [Poly(St-OH)-SUO] were verified by using FTIR and 1H-NMR analyses. Additionally, thermal properties of the samples were determined. The film properties of Poly(St-OH)-SUO samples prepared with different polymer/oil ratios and classic urethane oil were examined. Poly(St-OH)-SUO-40 sample exhibited the best film properties among the others. In the end, the obtained results showed that Poly(St-OH)-SUO-40 could be utilized as an oil-based binder.

Perte insensible en eauIndex. décimale : 668.5 Parfums et cosmétiques Résumé : To answer the increasing need for personalisation in skin and hair care routines and satisfy the pampering trend reinforced during the pandemic lockdown, the Oil Gel Emulsifier technology can be used to create products that are visually attractive. We have seen how, at a low use level of up to 5%, a translucent or transparent oil gel appearance can be achieved using the external and internal phases’ index-matching technique. The technology can help reinforce concepts for transforming textures and indulging the luxurious nourishing of oil formats. This oil gel technology can be deployed to innovate skin and hair routines to provide consumers with significant benefits they cannot find in existing regimens and traditional personal care products. Consumers are likely to be pleasantly intrigued by the transforming format and subsequent benefits the oil gel brings, along with the opportunity to enjoy a truly memorable, sensorial experience.
