Abstract

The invention relates to a therapeutic composition for broad spectrum dermal disease and in particular, to a composition comprising principal lipid components of skin, preferably having about 30 to 90% by weight of a carrier for applying to skin; 0.01 to 5.0% by weight of sphingolipid long-chain base; 0.001 to 1.0% by weight of lysophosphatidic acid; and 1 to 40% by weight of organic or inorganic additives. The composition is useful for the treatment and improvement of atopic dermatitis, psoriasis, acne, ichthyosis, infectious dermatitis, pruritus, erythema derived from pruritus, vulnus, chapping of skin and ulcer, etc.

Claims (13)

1. A therapeutic composition for topical application, consisting essentially of:

a sphingolipid long-chain base present at from about 0.01 to 5.0% and lysophosphatidic acid present at from about 0.001 to 1.0%,

wherein the sphingolipid long-chain base is one or more selected from the group consisting of phytosphingosine, acetylphtosphingosine, tetraacetyl phytosphingosine, hexanoylphytosphingosine and acetylphytosphingosine phosphate.

2. A therapeutic composition for topical application, consisting essentially of:

30 to 90% by weight of a substrate or a carrier for skin application;

0.01 to 5.0% by weight sphingolipid long-chain base;

0.001 to 1.0% by weight lysophosphatidic acid;

and 1.0 to 40% by weight of organic or inorganic additives, wherein the sphingolipid long-chain base is one or more selected from the group consisting of phytosphingosine, acetylphytosphingosine, tetraacetyl phytosphingosine, hexanoylphytosphingosine and acetylphytosphingosine phosphate.

3. The therapeutic composition according to claim 2 , wherein the organic additives contain ceramide, cholesterol and fatty acid.

4. The therapeutic composition according to claim 3 , wherein the organic additives contain a weight ratio of ceramide: cholesterol: fatty acid of from about 40 to 60%: from about 20 to 30%: from about 20 to 30%.

5. The therapeutic composition according to claim 2 , wherein the ceramide comprises one or more selected from the group consisting of: ceramide 3 ceramide 6, and a mixture thereof, and wherein the ceramide has the same stereochemical composition as the ceramide in human skin lipids.

6. The therapeutic composition according to claim 1 , wherein the lysophosphatidic acid is one or more selected from the group consisting of lyso-stearoyl phosphatidic acid (18:0), lyso-oleoyl phosphatidic acid (18:1), lyso-palmitoyl phosphatidic acid (16:0) and natural lyso-phosphatidic acid derived from egg yolk or beans.

7. The therapeutic composition according to claim 1 , wherein the composition is formulated into a form selected from the group consisting of: a cream, a lotion, an ointment, a skin toner, an essence, a body wash, and a shampoo.
