Pâteux (ingrédients cosmétiques)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Waxes and butters have been used for many centuries and continue to form an important group of raw materials for the cosmetics sector. It would be impossible for us to produce a lipstick or mascara without waxes. Butters have important active benefits and skin feel qualities.
There is a wide choice within this category and the combination in which they can be used is endless, thus allowing the formulator to create an infinite array or rheologies, textures and fuctional benefits. The raw materail choice will be governed by cost, performance and if the materials should be natural. Consumer demand for natural cosmtecis is strong and therefore the natural options available from this group of materials are such in demand.Note de contenu : - WAXES : Beeswax - Carnauba wax - Candelilla wax - Green tea wax - Rice bran wax - Laurel wax - Polyethylene wax

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.
PolyoléfinesUne polyoléfine, parfois appelée polyalcène, désigne un polymère aliphatique saturé, synthétique, issu de la polymérisation d'une oléfine (aussi appelée un alcène) telle l'éthylène et ses dérivés.
La formule générale est -(CH2-CRR')n-, où R et R' peuvent être l'atome d'hydrogène (H) ou les radicaux alkyle apolaires CH3, CH2-CH3, CH2-CH(CH3)2. Il existe aussi des mousses isolantes souples faites à partir de polyoléfine (pour l'isolation thermique de tuyaux plastiques par exemple).
PRESENTATION : Les polyoléfines forment la plus importante famille de matières plastiques, avec quatre représentants (PP, HDPE, LDPE, LLDPE) parmi les plastiques de grande consommation. La consommation mondiale de ces quatre polymères est évaluée à plus de 60 millions de tonnes en 20001.
Seul un petit nombre de polyoléfines a atteint le niveau industriel :
les polyoléfines thermoplastiques semi-cristallines : polyéthylène (PE), polypropylène (PP), polyméthylpentène (PMP), polybutène-1 (PB-1) ;
les polyoléfines élastomères : polyisobutylène (PIB), éthylène-propylène (EPR ou EPM) et éthylène-propylène-diène monomère (EPDM).
PROPRIETES : En raison de leur nature paraffinique, les polyoléfines sont hydrophobes et possèdent en général une grande inertie chimique (aux solvants, acides, bases, etc.). Ces matériaux ont donc une qualité alimentaire. Le collage est très difficile (la surface est particulièrement inerte, des traitements de surface spéciaux sont nécessaires).
Cependant, ils sont sensibles à l'action des UV, et résistent très peu à l'inflammation car leur indice limite d'oxygène est faible (exemple : ILO ~ 17 pour le polyéthylène).
Leur densité est très faible [0,83 (cas du PMP) < d < 0,95] : ils flottent dans l'eau.
Ils sont opaques, sauf le PMP (transparent).
Primaire (revêtement)Index. décimale : 667.9 Revêtements et enduits Résumé : The optimization of various key ingredients in paint formulations using traditional designing methods has been a difficult task for paint formulators. To overcome such limitations, combinations of alternate methods of DOE i.e Analysis of variance along with Response surface method mainly contour plots were utilized to provide most optimized compositions in the paint formulations. In the present case study, metallic basecoat silver formulation was studied for the key ingredients i.e. Organo clay solution, Polyamide waxes and Polyolefin waxes for their effect on settling behavior and metallic flip flop effect. To understand the significance level, initially full factorial study was done by fixing two levels of these factors, based on the findings further experimentation was done using Mixture Design. All three factors were studied independently through Trace plots and studied through first order model of regression coefficients. Analysis of variance was used to check fitness of model and its significance was validated with F-test at more than 95% significance level. Contour plots provide best region for optimized responses of Antisettling properties and flip flop effect. The results from contour plots were verified and validated through experimental work to reconfirm the results. From this study, it can be understood that the response surface methods can help optimize the mixture designs like paint formulations best way to achieve favorable results for more than one response at a time.

Rouges à lèvresIndex. décimale : 668.5 Parfums et cosmétiques Résumé : This very popular lipstick has an eclectic mixture of the very naturel and the very synthetic. The origin of the materials seems not to have been a factor in their selection. They have concentrated on picking the best tool for the job. As it happens, the bulk of the constituents are naturel and sustainable. In the hands of those creative folks in marketing departments this lipstick could easily be made to sound like something so wholesome you would rather spread it on a suite of wholemeal bread than on your lips. It is certainly a lot greener than say a shampoo whose only nod in the direction of the environment is some essence of some herb.
But I think the Mac team are wise in steering clear of the naturalness of their product in their promotion. Fashions can change very quickly. A lot of products that make a big play of their naturel credentials are not necessarily all that good. This is something the consumers might begin to notice. Or more likely, they will just not buy them again if they do not enjoy them. But good formulations will always find fans. By selecting the best functional ingredients they have created a product that people want to use again and again.
I think there is a lesson here for all of us engaged in product development. At the end of the day how comforting the ingredient list reads is not that big a factor. It is what the ingredients do that is important. There are some great naturel raw materials available, particularly when you are looking at waxes and butters. As this Mac lipstick shows, naturel waxes can be the bedrock of a great formulation. But make sure you are using them because they are great, not because they are naturel.Note de contenu : - Castor oil

SurfactantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : People's perception of natural is an interesting one — namely if it is natural then it must be good. This is particularly true of the cosmetic consumer. Certain aspects of the media deplore the use of preservatives in our cosmetics. Yet how would they feel about the presence of mould ? It is alter all natural but I suspect it would be an unwelcome addition to your favourite face cream.
Psychologically we are geared to believe that natural is always the best option. This is probably due to our associations with food — we know that fruit is good for us therefore fruit extracts, with their essential vitamins, are good for our hair and skin. This is of course true but marketing stories often lead us to believe that something is more natural than it really is. We have all seen adverts for a cosmetic where the advertised product is placed in beautiful natural surroundings and we are told how this product contains some beneficial natural ingredient. The inference is that this is a natural product. While it does contain one or more natural materials to fit with the marketing story, in most cases it will have them at a low percentage while the bulk of the product is composed of synthetics.Note de contenu : - How natural is natural ?
