Definitions
- the present invention concerns methods of treating skin with compositions containing certain esters of salicylic acid and use of such esters in such compositions.
- Dermatologic disorders include such conditions as acne, dry skin, dandruff, keratosis, pruritus, inflammatory dermatoses, eczema, psoriasis and tenia pedis (athlete's foot).
- Chronoaging results in the thinning and general degradation of skin. As skin naturally ages, there is reduction in the cells and blood vessels that supply the skin. There is also a flattening of the dermal-epidermal junction which results in weaker mechanical resistance. Older individuals increasingly develop facial fine lines, wrinkles, leatheriness, yellowing, sagging, mottling (hyperpig entation) , age spots and the general signs of aging.
- Extrinsic factors are primarily those caused by exposure to sun. Changes are most prominent in light skinned individuals who burn easily and tan poorly. The results of photodamage may be identical to those of aging except appearing at an accelerated rate. Wrinkling, yellowing, leatheriness, mottling and hyperpigmentation are all associated with sun damage. Most disturbing to many individuals is the wrinkling effect. It is a prime reminder of the disappearance of youth. As a result, there have been many reports of cosmetic treatments aimed at the elimination of wrinkles.
- Ring alkylated salicylic acid has been reported in Japanese Patent 4036238 (Takasago Perfumery KK) for treatment of acne vulgaris.
- dermatologic disorders such as acne, dry skin, dandruff, keratosis, pruritus, inflammatory dermatosis, eczema, psoriasis and tinea pedis.
- Another object of the present invention is to provide a cosmetic treatment for chronoaging conditions including wrinkling and fine lines, leatheriness, yellowing, sagging, mottling (hyperpigmentation), age spots, thinning of the skin, loss of elasticity, loss of collagen and the general signs of aging.
- Still another object of the present invention is to provide a cosmetic treatment against environmental abuse to skin including wrinkling and fine lines, yellowing, leatheriness, mottling and hyperpigmentation.
- Yet another object of the present invention is to provide a treatment to improve the condition of skin with a composition and active that does not impart irritation.
- R is a C n -C 30 alkyl or alkenyl radical.
- the invention also encompasses the use of a salicylate ester as described above in a composition for topical application to the skin as an active for treating a skin condition selected from the group consisting of dermatologic disorders, chronoaging and environmental abuse.
- R is a C n -C 30 alkyl or alkenyl radical.
- Preferred are the C 12 -C 20 alkyl or alkenyl, optimally the C 13 alkyl or alkenyl esters of salicylic acid. The most preferred is tridecyl salicylate.
- the ⁇ sent invention applies in particular for such derm ⁇ -logic disorders as a ne, dry skin, dandruff, kerat-sis, pruritus, inflammatory dermatitis, eczema, psoriasis and tinea pedis.
- chronoaging it applies particularly for conditions involving wrinkling, fine lines, leatheriness, yellowing, sagging, hyperpigmentation, age spots, thinning of the skin, loss of elasticity, loss of collagen and/or general signs of aging.
- Use of the present salicylate ester in skin care compositions for treating skin that has been subjected to environmental abuse is in particular beneficial in case of conditions exhibiting wrinkling, fine lines, leatheriness, yellowing, mottling and/or hyperpigmentation.
- Safe and effective amounts of the C n -C 30 esters of salicylic acid are to be used within cosmetic compositions of the present invention.

- a cre e was prepared having a composition described in Table II.
- Carbopol 1382® (2% Solids) 18.000
- the test panel was comprised of 45 female human volunteer subjects (21 using Example 1 and 24 using Example 2). Enrolled subjects had a facial acne grade of II (Pilsbury) or lower and no facial irritation beyond the specific acne lesions.
- the investigator assessed the global facial irritation and acne condition of each subject.
- the lighting conditions, fluorescent overhead lights in a fluorescent ring lamp with a diopter lens (as needed) were identical for each evaluation.
- Each subject used either product twice daily (morning and evening) for twenty-eight days, recording all use on a diary form.
- the investigator's global facial assessments of open lesions, closed lesions, papules, pustules, nodules and irritation were transferred via data entry from the original data sheets to computer. Analysis was conducted using the paired sample t-Test on the global mean scores within each product group and on the differences from baseline in global mean scores for a product vs. product comparison. Significance was assessed at the p 0.05 level (95% confidence) .
- Example 2 Although the compositions of Example 1 and 2 vary slightly, the major difference is the presence of 4% tridecyl salicylate in Example 2. From the above study, it is evident that the tridecyl salicylate had a significant effect upon treating the conditions of acne while being nonirritating.
- a microemulsion formulation according to the present invention is outlined under Table III.
- a skin lotion (water in oil type) formulation according to the present invention is outlined under Table IV.
- a skin cream (oil in water type) formulation according to the present invention is outlined under Table V.
- An anhydrous serum formulation according to the present invention is outlined under Table VI.
- a skin lotion (oil in water type) formulation according to the present invention is outlined under Table VII.
- a protective skin lotion with sunscreen formulation according to the present invention is outlined under Table VIII.
- the crepey skin protocol is a clinical visual assessment of forearm skin. This condition is associated with photoaged skin and reflects skin which takes on a sagging, rough, wrinkled appearance.
- the clinical test is 12 weeks in duration and evaluates 2 different test formulations in a paired manner (one on each forearm) using 15 women with moderate forearm crepiness.
- the study is conducted in a double blinded manner where neither the subject or clinical evaluator has knowledge of the test material being applied to the forearms. Only subjects with equivalent crepiness on both forearms are enrolled.
- a directed-difference scale is used to quantitate any perceived difference between right and left treated forearms. If there is no perceivable difference between forearms a 0 is noted. In the event one forearm is better, the more improved forearm i ⁇ iven a score from 1 to 4 (smallest to greatest) where these values represent a difference level of improvement over the companion treated forearm. The forearm which is showing greater improvement will therefore attain a higher average absolute score.
- Results of the clinical are provided in Table X. They show that the tridecyl salicylate formulation is superior to the vehicle. This is evident as the directed difference scores are in the negative direction favouring the tridecyl salicylate formulation. The only difference between the vehicle and experimental formulations is tridecyl salicylate. All other ingredients, pH, etc. are the same.
