  • Publication number: 20260294761
    Abstract: The invention relates to a micellar aqueous cleansing composition featuring a natural thickener comprising lauryl lactate and at least one or a combination of polyquaternium cationic polymers. This composition is formulated to exclude any added PEG-based ingredients, including PEG/PEO polymeric thickeners, as well as sulfate-based ingredients, such as sulfate-based surfactants. The exclusion of these ingredients is aimed at reducing potential irritants and synthetic compounds. The resulting formulation achieves a gel-like viscosity and maintains a transparent appearance, offering a gentle and effective cleansing solution with improved stability and skin compatibility.

  • Publication number: 20260294750
    Abstract: A foaming cleanser is disclosed, comprising at least one fatty alcohol, at least one amphoteric surfactant, at least one anionic surfactant, and water, wherein the formulation is free of PEG based ingredients. In some embodiments, the cleanser formulation is further characterized by the exclusion of PEG/PEO polymeric thickeners, parabens, and combinations thereof. The cleanser may specifically exclude PEG-150 pentaerythrityl tetrastearate, PEG-6 caprylic/capric glycerides, or combinations thereof, providing a milder and more environmentally friendly alternative for skin care applications. This formulation ensures effective cleansing and foaming properties while minimizing potential irritants, making it suitable for all skin types, including sensitive skin.

  • Patent number: 12735656
    Abstract: A monophasic micellar water cleansing composition includes a combination of surfactants that include at least one biosurfactant and at least one polyglycerol ester surfactant, in particular, one of polyglycerol-3 and polyglycerol-4 ester surfactants, wherein the combination of surfactants provides a water rinsible composition that is visually clear and pleasing on application with high makeup removability. More particularly, the composition provides highly effective makeup removal exceeding the performance of at least one commercial benchmark having components that are considered effective but less desirable due to the presence of ingredients that are harsh and less natural. The micellar cleansing composition has a pH in a range from about 4 to about 8, and may be essentially free or free of PEG/POE surfactants.

  • Patent number: 12728080
    Abstract: A cosmetic kit is disclosed having a container and a shaving cap. The container comprises interior chamber containing a solidified gel of a micellar solution and a dispensing opening that exposes an outer surface of the solidified gel. The exposed surface of the solidified gel to a surface, like skin, and can be cleaned with the shaving cap, which removes at least a portion of the exposed surface of the solidified gel. The shaving cap comprises a planer surface and one or more openings or slits through the planar surface having shaving edges that shave the exposed surface of the solidified gel when applied against the exposed surface, for example, by rotating the shaving cap relative to the container with sufficient force to overcome shearing resistance of the solidified gel. The cosmetic kit is particularly useful for hygienically cleansing the skin.
