Pregled kozmetičnih izdelkov za zaščito las pred toplotno obdelavo

Hriberšek, Katarina (avtor), Ahlin Grabnar, Pegi (mentor)

Lasje so pomemben del človekove podobe in ena izmed prvih vizualnih lastnosti, ki jih pri človeku opazimo. V želji po urejeni pričeski pogosto uporabljamo toplotne pripomočke, kot so sušilniki, likalniki in kodralniki, ki omogočajo hitro oblikovanje las, hkrati pa povzročajo poškodbe lasne strukture. Redna izpostavljenost visokim temperaturam oslabi povrhnjico las, zmanjša njihovo elastičnost in povzroči izsušen videz. Prav zato kozmetični izdelki za zaščito las pred toplotno obdelavo postajajo nepogrešljiv del rutine posameznikov. S pomočjo teh izdelkov lahko zmanjšamo škodljive vplive toplote, saj na površini las ustvarijo zaščitni film, ohranjajo vsebnost vode v lasnem vlaknu ter lasem povrnejo sijaj in zdrav videz. V diplomski nalogi smo proučevali kozmetične izdelke za zaščito las pred toplotno obdelavo. V lekarnah, drogerijah in na spletnih straneh smo izbrali 58 kozmetičnih izdelkov za zaščito las pred toplotno obdelavo in proučili njihovo sestavo. Osredotočili smo se na aktivne sestavine, ki prispevajo k zaščiti las pred toplotno obdelavo in pogostost njihovega pojavljanja v izbranih izdelkih. Ovrednotili smo tudi pogostost pojavljanja dišav in konzervansov. Ker ima pri odločitvi za nakup pomembno vlogo tudi cenovna dostopnost izdelka, smo pozornost namenili tudi cenovnemu razredu izbranih kozmetičnih izdelkov. Pregledali smo tudi oglaševane maksimalne temperature, do katere naj bi izdelki nudili zaščito. Ugotovili smo, da k učinkovitemu delovanju izdelka prispevajo predvsem silikoni, polimeri in hidrolizati proteinov. K delovanju izdelka pa prispevajo tudi humektanti, emolienti in rastlinski izvlečki. Najpogosteje uporabljena silikona sta dimetikon in amodimetikon. Med polimeri prevladujejo polikvaterniji, ki smo jih zasledili v 28 kozmetičnih izdelkih. Med hidrolizati proteinov smo najpogosteje zasledili hidrolizirane pšenične proteine. Med humektanti je prevladoval glicerol, med emolienti pa poleg silikonov cetearilni alkohol. V izbranih izdelkih smo zasledili 46 različnih naravnih izvlečkov. Med dišavnimi sestavinami sta bila najpogostejša linalol in limonen, med konzervansi pa fenoksietanol in natrijev benzoat. Ugotovili smo, da prevladujejo izdelki iz nižjega cenovnega razreda in izdelki, ki navajajo zaščito do 230 °C.

• Naslov: Review of cosmetic products for heat protection of hair

Izvleček

Hair is an important part of a person's appearance and one of the first visual features we notice in a person. In the desire to get a neat and stylish hairstyle, we often use heat appliances such as blow-dryers, flat irons and curling irons, which allow us to style our hair quickly, but at the same time they cause damage to the hair structure. Constant exposure to high temperatures weakens the hair cuticle, reduces its elasticity and causes dry appearance of hair. This is why cosmetic products for heat protection of hair are becoming a necessary part of people's routine. These products can reduce the damage effects of heat by creating a protective film on the surface of the hair, preserving the water content and restoring shine and a healthy appearance. In this diploma, we studied the composition of cosmetic products for heat protection of hair. We randomly chose 58 products from pharmacies, drugstores and websites and studied their composition. We focused primarily on ingredients, that contribute to the protection of hair against heat and their frequency of occurrence in chosen products. We also analyzed fragrances and preservatives. As affordability also plays an important role in purchasing a product, we also focused on the price range of the selected cosmetic products. We also reviewed the advertised maximum temperatures up to which the products are claimed to offer protection. We found out that silicones, polymers and hydrolyzed proteins are the main contributors to the product's effective functioning. Humectants, emollients and plant extracts also contribute to the function of the product. The most common silicones used are dimethicone and amodimethicone. Among polymers polyquaterniums were most commonly found. Among hydrolyzed proteins, hydrolyzed wheat protein was most frequently present. Among humectants, glycerol was the most prevalent, and among emollients, besides silicones, cetearyl alcohol was most common. In chosen products we found 46 different natural extracts. The most commonly used fragrance ingredients were linalool and limonene, while phenoxyethanol and sodium benzoate were the most common preservatives. We found out that lower-priced products predominating and those claiming protection up to 230 °C.
