Abstract
Disclosed are methods and topical compositions for applying bacteria to skin, scalp and hair. The topical compositions include bacteria in a suitable base vehicle comprising honey for applying the bacteria to skin, scalp and hair. The base vehicle may include additional components such as, but not limited to, plant-based products, micro-nutrients, emollients and plant-sourced emulsifiers, and anti-oxidants, among other components. The topical compositions may be utilized in methods for treating and/or preventing skin, scalp, and hair conditions such as, but not limited to, dry skin, dry scalp, dandruff, psoriasis, cradle cap, seborrheic dermatitis, and/or eczema.
Core Innovation
The invention provides methods and topical compositions for applying bacteria to skin, scalp, and hair. The central feature of the compositions is the inclusion of bacteria in a suitable base vehicle that comprises honey. The vehicle may further include plant-based products, micro-nutrients, emollients, plant-sourced emulsifiers, and antioxidants.
This invention deals with the limitations of current skin and scalp products, which often are not compatible or supportive of the skin microbiome and pH. Existing products may include pharmaceutical agents, synthetic detergents, skin-irritating preservatives, and biocides that are not in biological parity with the skin or its microbiome and may cause side effects or irritation.
The disclosed topical compositions aim to support and be compatible with the skin microbiome and pH. They use honey as the base along with optional other components and bacteria, which may be live or killed. The compositions may be used to treat and/or prevent conditions such as dry skin, dry scalp, dandruff, psoriasis, cradle cap, seborrheic dermatitis, and eczema.
Claims Coverage
There are three independent claims in this patent, each introducing a distinct inventive feature.
Scalp mask cream comprising killed lactobacillus species and honey for treating dry scalp conditions
A scalp mask cream that includes killed Lactobacillus acidophilus, killed Lactobacillus plantarum, killed Lactobacillus bulgaricus, and honey. The scalp mask cream is applied to the scalp to treat a dry scalp condition.
Skin cream containing killed lactobacillus species, turmeric, and honey for treating scalp conditions
A skin cream for treating a scalp condition, the skin cream comprising bacteria, turmeric, and honey, wherein the bacteria comprise killed Lactobacillus acidophilus, killed Lactobacillus delbruecki, and killed Lactobacillus plantarum. The skin cream is applied to the scalp to treat a dry scalp condition.
Skin cream with killed lactobacillus species, turmeric, vitamin B12, and honey for treating dry scalp, skin or hair
A skin cream for treating a scalp condition, comprising bacteria, turmeric, Vitamin B12, and honey. The bacteria comprise killed Lactobacillus acidophilus, killed Lactobacillus delbruecki, and killed Lactobacillus plantarum and the skin cream is used to treat dry scalp, skin, or hair.
The inventive features claimed are topical compositions (scalp mask cream or skin cream) for treating dry scalp or skin conditions, each defined by the inclusion of specific killed bacterial strains in combination with honey and, optionally, turmeric and vitamin B12.
Stated Advantages
The compositions are formulated to be supportive and compatible with the skin microbiome and pH.
The invention provides a shelf-stable, nutrient-rich vehicle for delivering bacteria to the skin, scalp, and hair.
The topical compositions avoid the use of common skin-irritating components found in standard products, such as preservatives, biocides, and synthetic detergents.
The compositions serve as alternatives to conventional treatments that may have significant side effects, such as corticosteroids and immunosuppressants.
The invention aims to improve the condition of the skin, scalp, and hair, potentially enhancing cosmetic character and general health.
Documented Applications
Application to treat and/or prevent skin, scalp, and hair conditions, including dry skin, dry scalp, dandruff, psoriasis, cradle cap, seborrheic dermatitis, and eczema.
Application for treating atopic dermatitis, seborrheic dermatitis, and dry scalp in adults and pediatric subjects.
Application as a scalp mask product for subjects with dry scalp and dandruff, improving symptom severity and quality of life measures.
