Abstract

Objective — using skin application samples to test for allergenicity of some cosmetic and hygienic environmentally friendly products of the CHOICE campany in patients with chronic recurrent dermatosis — eczema, atopic dermatitis and psoriasis. Materials and methods. With the help of skin application tests, some cosmetic and hygiene products of the CHOICE (Ukraine) company were tested in 36 patients with the most common chronic recurrent dermatosis — eczema, atopic dermatitis and psoriasis. The test products were applied to dry skin, free from rashes and topical medications, under a medical patch. Samples were counted on the 2nd, as well as on the 4th—5th and 7th—8th days after application. Results and discussion. No skin reactions were recorded in patients with psoriasis who participated in the study. The phenomena of contact dermatitis were observed in contact with only one type of tested product, namely, «Gentle Phytomousse» of the «Seaweed» line for washing all skin types. This type of product was allergenic for 1 out of 6 patients with true eczema and 4 out of 9 patients with atopic dermatitis. Other types of products did not cause any phenomena of contact dermatitis at all in the observed patients. Conclusions. Four of the five CHOICE (Ukraine) products tested by skin application trials, namely: ECO liquid soap, Green max.; egg shampoo for dry and damaged hair line Intensive Moisturizer, White mandarin; Soft and velvety skin hand and body milk, White mandarin; Soft and velvety skin shower gel, White mandarin can be used in patients with eczema, atopic dermatitis and psoriasis without prior allergy testing. Gentle Phytomousse for washing all skin types of the Seaweed line can cause contact dermatitis in patients with true eczema and atopic dermatitis.
