preparation example Construction

[0174] Methods of preparation of the compositions of the present invention are generally conventional methods known in the art of preparing topical compositions. These methods generally involve mixing the ingredients into a relatively uniform state in one or more steps, with or without heating, cooling, vacuum, and the like. Ways to Regulate Skin Condition

[0175] The compositions of the present invention are useful for regulating the condition of mammalian skin (particularly human skin, more particularly human facial skin), including visible and / or tactile skin unevenness, signs of skin aging, and skin aging-related Visible and / or tactile unevenness (including fine lines, wrinkles, large pores, surface roughness, and other textural unevenness associated with aging skin) These modulations include prophylactic and therapeutic modulations.

[0176] Regulating skin condition generally involves applying to the skin a safe and effective amount of a composition of the present inven...

Embodiment 1

[0184] Phase A components were first combined and sparged with nitrogen for about 15 minutes. The Phase B components were then dispersed into Phase A with a paddle mixer until homogeneous and heated to about 75°C. In a separate vessel, combine Phase C ingredients and heat to about 75°C. The mixture of Phase A and Phase B was then blanketed with a slow steady stream of nitrogen. The Phase C ingredients are then homogenized into the Phase A and Phase B mixture in about 15 minutes using any rotor / stator type homogenizer. After 15 minutes, turn the mixer off to low speed sweep mixing. The Phase D components are then combined and added to the Phase A, B and C mixture. Once phase D is mixed in and the batch mixture is homogeneous, cool the entire batch. When the batch has cooled to about 50°C, add the Phase E ingredients and homogenize. When the batch had cooled to about 40°C, the Phase F ingredients were added. Finally, when the batch had cooled to about 30°C, the Phas...

Abstract

Disclosed are skin care compositions containing a vitamin B3 compound which generally improve the quality of the skin, particularly human facial skin. More particularly, the present invention relates to niacinamide containing skin care compositions with improved skin compatibility.

Description

technical field [0001] The present invention relates to skin care compositions containing vitamin B3 which improves the quality of skin in general, especially on the human face. More specifically, the present invention relates to skin care compositions containing niacinamide having improved skin compatibility. Background of the invention [0002] Many personal care products available to consumers today are primarily intended to improve skin health and / or physical appearance. Many of these skin care products are aimed at delaying, reducing or even eliminating skin wrinkles and other permanent lesions generally associated with skin aging or environmental aggression to human skin. [0003] The skin is attacked by many extrinsic and intrinsic factors. Extrinsic factors include ultraviolet radiation (such as from exposure to sunlight), environmental pollution, wind, heat, low humidity, harsh surfactants, abrasives, etc. Intrinsic factors include chronic a...
