Cosmetic Truth of the month : BRUT Antiperspirant Stick

 

Component Analysis BRUT Antiperspirant :

The formula starts off powerfully with Cyclopentasiloxane in first position, a silicone based substance, suspected of being an endocrine disruptor. Next is an aluminium salt, Aluminum Zirconium Tetrachlorohydrex GLY, which is particularly problematic.

What’s the problem with aluminium salts in cosmetics?

Aluminum salts are reactive components, partially soluble, that can penetrate the body’s tissues. For some time now aluminium salts have been singled out in various studies, but the two most recent studies have once again revived the debate on the connection between aluminium salts in deodorants and the development of cancer.

A 2016 Swiss study* considered the implications of aluminium in the development of breast cancer. The study, by André-Pascal Sappino and Stefano Mandriota showed that deodorants containing aluminium salts cause tumours in guinea pigs.

« International Journal of Cancer”, Geneva, September 2016

And another study carried out last summer, Innsbruck Austria (July, 2017)*, published in EBioMedicine, particularly linked certain aluminium salts to the risk of developing breast cancer.

*http://www.sciencedirect.com/science/article/pii/S2352396417302335

The findings of this study: For those who, from an early age, have been using an antiperspirant containing aluminium salts several times a day on shaved underarms, the risk of developing breast cancer is doubled.

As is often the case, the authorities’ response* which is intended to reassure, proposes concentration restrictions (0.6%) which are not always respected.

*http://ansm.sante.fr/S-informer/Points-d-information-Points-d-information/Evaluation-du-risque-lie-a-l-utilisation-de-l-aluminium-dans-les-produits-cosmetiques-Point-d-information

« The data analysis proposed a restriction of aluminium concentration to 0.6% in antiperspirant or deodorant products.

It should be noted that this restriction doesn’t apply to damaged skin being exposed to it, such as after shaving or micro cuts.

Therefore, the Afssaps (French Health Products Safety Agency) recommends not to use antiperspirants containing aluminium on damaged skin.”

But the restriction recommendation remains only a suggestion.

According to information from the BfR* (German Federal Institute for Risk Assessment) « amounts of 20% are quite common in antiperspirants ». This would correspond to an aluminium content of about 5%.

The German Federation of Cosmetics and Cleaning Products Professionals’ newsletter (Industrieverbandes Körperpflege- und Waschmittel e.V. (IKW) reports concentrations of aluminium hydrochlorides of up to 30%, in antiperspirant creams for example. (IKW, 2012).

And there are other issues:

Aluminium salts block the sweat glands

Aluminum hydrochlorides and sulphates used in many conventional deodorants prevent sweat from beading on the surface of the skin, so they clog pores. This can lead to itching and skin irritation.

A distinction must be made with regard to aluminium-based components:

However, not all components that are called, or whose names begin, in INCI terms with « Aluminum » or « Alumina », are « aluminium salts ».

It is important to distinguish between aluminium hydrochlorides* and aluminium oxides, hydroxides and silicates** (which are also part of the composition of clays, for example, see « bauxite » or « corundum », naturally present in the earth).

*Aluminium chlorohydrates (among others)

  • Aliminium Chloride
  • Aluminium Chlorhydrate
  • Aluminium Chlorhydrex
  • Aluminium Chlorhydrex PG
  • Aluminium Distearate
  • Aluminium Sesquichlorohydrate
  • Aluminium Starch Octenylsuccinnate
  • Aluminum Zirconium Tetrachlorohydrex GLY

**Aluminium oxides/Hydroxides (among others)

+ Alumina (= aluminiumhydroxyde)

+ Aluminium/Magnesium Hyroxide Stearate

+ Aluminium Starch Otenylsuccinate

+ Aluminium Silicate

Aluminium oxides, silicates and hydroxides are chemically inert aluminas, i.e. they are not chemically reactive as they stand.

Aluminum oxides and hydroxides do not release aluminum, but this may be the case with aluminum hydrochlorides, which are considered soluble.

(By the way, avoid cooking food in foil with lemon… it is a sure way to increase aluminium content in food and therefore to absorb it)

And now back to our product, the BRUT Antiperspirant stick :

Benefits of KOLs for Your Marketing Strategy

  1. A KOL can help you target your ideal audience. Whether you're interested in boosting awareness or generating leads, a KOL can help you quickly identify and reach your ideal audience. Essentially, a KOL has done all the hard work for you -- she's taken the time to engage with a specific, niche audience, and she's grown a community centered around a specific interest. A KOL is a particularly powerful opportunity to reach your ideal audience. For instance, let's say your business sells organic smoothie products. Your product is relatively niche, so you don't necessarily need to cast a wide net when attracting and engaging new leads. Rather than posting Facebook ads or cultivating a strong presence on Google, you might be better off reaching out to a KOL like Massy Arias, who has 2.5 million followers and posts content exclusively related to health and fitness. Since Arias' typically posts organic health and fitness content and has proven an expert in this real

The 7 Biggest Things You Need to Know About Vitamin C Serums

  There are a zillion forms of vitamin C. Most vitamin C derivatives are thought to have the same effect (they can tone down redness, hyperpigmentation and signs of aging), but some forms have added benefits and are better studied, says Dr. Sode. The most popular and effective: L-ascorbic acid  —i.e., pure vitamin C—has the most research behind it and tends to be the strongest (but most sensitizing). Try: SkinCeuticals C E Ferulic Acid Tetrahexyldecyl ascorbate  is fat soluble, meaning it can penetrate deeply and effectively into your skin. Try: Revision Skincare® C+ Correcting Complex 30%™ Magnesium ascorbyl phosphate  can increase hydration levels in dry skin and prevent water loss. Try: 100% Pure Vitamin C Serum Sodium ascorbyl phosphate  tends to have a neutral pH (making it gentle on sensitive skin), along with acne-inhibiting effects.
