  "abstract": "The invention provides cosmetic compositions comprising microalgal biomass, whole microalgal cells, and/or microalgal oil in combination with one or more other cosmetic ingredients, and methods of making such compositions. In preferred embodiments, the microalgal components of the cosmetic compositions are derived from microalgal cultures grown heterotrophically and which comprise at least 10% oil by dry weight.",
  "claims": [
    "1. A method for promoting the prevention or repair of skin aging comprising applying to the skin a composition, the composition comprising at least 1% w/w Chlorella oil comprising less than 500 ppm of chlorophyll, Alaria esculenta extract and optionally, an ingredient selected from the group consisting of a retinoid, ceramide, and Cymbopogon martini oil, wherein the Chlorella oil reduces thymine dimerization in a skin cell when the skin is exposed to UVB radiation.",
    "2. The method of claim 1, wherein the Alaria esculenta extract is present at a concentration of 0.1-2.0%.",
    "3. The method of claim 1, wherein the composition further comprises at least one of rosemary extract, cetearyl ethylhexanoate, isopropyl isostearate, tocopherol, and caprylic/capric triglyceride.",
    "4. The method of claim 1, wherein the composition further comprises a retinoid or a ceramide.",
    "5. The method of claim 4, wherein the retinoid in the composition is present at a concentration of 0.01-2%.",
    "6. The method of claim 4, wherein the ceramide in the composition is present at a concentration of 20-40%.",
    "7. The method of claim 1, wherein the Chlorella oil present in the composition is present at a concentration of 10-50%.",
    "8. The method of claim 1, wherein the Chlorella oil is present in the composition at a concentration of 10-50%, the retinoid is present in the composition at a concentration of 0.01-0.2%, and, optionally, the ceramide is present in the composition at a concentration of 20-40%."

  "description_excerpt": "The invention resides in the fields of cosmetics, cosmetics ingredients, and aquaculture.\n\nSeed oils or animal fats have been used in conventional cosmetic products for years. Oils from plants are typically obtained from cultivation or harvesting wild biomass. The composition of plant oils changes in response to weather, seasonal influences such as photoperiod, temperature, soil acidity, soil salinity, and pests.\n\nIn one aspect, the present invention is directed to a cosmetic composition comprising at least 1% w/w microalgal biomass and at least one other cosmetic ingredient, in which the microalgal biomass comprises at least 10% microalgal oil by dry weight. In some cases, the biomass contains at least 25% microalgal oil by dry weight. In other cases, the biomass contains at least 35% microalgal oil by dry weight. In yet other cases, the biomass contains at least 45% microalgal oil by dry weight. In still other cases, the biomass contains at least 55% microalgal oil by dry weight. In at least one embodiment, the biomass comprises predominantly intact algal cells.\n\nIn some embodiments of the cosmetic composition described above, the biomass contains 10-90% microalgal oil by dry weight. In some cases, the biomass contains from 25-80% microalgal oil by dry weight. In other cases, the biomass contains from 35-70% microalgal oil by dry weight. In still other cases, the biomass contains from 45-60% microalgal oil by dry weight.\n\nIn various embodiments of the cosmetic compositions in accordance with the present invention, the composition comprises at least 1% w/w microalgal biomass.",
