Today several grades of azelaic acid are

available, some of them are derived from animal sources some other from vegetable sources. Azeco Cosmeceuticals has developed and placed on the market an ultra-pure, micronised cosmetic-grade of azelaic acid with vegetable origin, COSMOS approved. Table 1 shows the main characteristics of this

grade of azelaic acid. This grade of azelaic acid is an ideal

active ingredient for a variety of personal care products (also COSMOS / ECOCERT approved) intended for African people with dark skin tone, providing all together important benefits that these class of consumers desire. Table 2 offers a brief overview.

tone, Azeco Cosmeceuticals has developed some finished formulas based on 10% of its azelaic acid (micronised, then easy to be formulated) to be used daily (once or twice a day) for African skin face to brighten dark spots, and even skin tone. As an example we report here the data relative to a non- comedogenic and hypoallergenic serum able to act against hyperpigmentation caused by breakouts. While it is targeted towards all skin types, those with oily and acne-prone skin may find the best results because it is oil free. Consistently applied will help to keep breakouts at bay and decongest clogged pores. Formulation 1 contains the formulation,

while just after the tips on how prepare an homogeneous gel are reported.

Procedure: In a melter, add all the ingredients of Phase A, heat to 60°C and mix until homogeneous: a yellowish transparent fluid gel is obtained. Cool to T <30°C. Once phase A has cooled, add and mix Xylityl sesquicaprylate and Tocopheryl Acetate . Indicative time 10 min, until transparency. Prepare Phase C, dispersing Sodium Polyacryloyldimethyl Taurate in water. Add Phase C to the mixture of Phase A and B, while stirring. Continue until a homogeneous gel is formed. Add the ingredients of Phase D, flush, possibly only gentle mixing and possibly with a very low force turbine, to avoid incorporating air. A whitish-yellowish gel is obtained.

process from a definite vegetable source (sunflower oil) is the perfect choice for high- performing (multi-action) and sustainable cosmetic solutions for the skin of African people. Using only one active, it is possible to

obtain a whole series of positive actions on the skin of African people with dark skin. In fact, topical azelaic acid, having anti-

inflammatory and antibacterial properties, in addition to comedolytic action and competitive inhibition of tyrosinase, an enzyme involved in the conversion of tyrosine to melanin, may effectively reduce epidermal hyperkeratinisation, one of the most common diseases of the skin of black African people.
