Basic of cleansing

Explore the first essential skincare step, cleansing, which removes substances to improve moisturizer and active-ingredient penetration; learn makeup composition and cleansing formulations, including oil, non-ionic, and ionic surfactants.

Examine cleansing balm and oil cleansers formed by reversed micelles, and learn how oil-in-water emulsions rinse away makeup, guided by HLB balance and surfactant choices.

Analyze a cleansing oil formula with surfactants and liquid oils, noting 0.5 to 2% water forms reversed micelles to boost makeup cleansing, and butter balm example uses NIKKOL TGI-20 20%.

Oil or liquid cleansers rely on a bi-continuous phase with oil and water channels, lowering tension to dissolve both water- and oil-soluble makeup via emulsifier–oil polarity balance (HLB around 10).

Explore how oil gel cleansers use D-phase liquid crystals and non-ionic emulsifiers to break down makeup, emulsify with water, and melt into a clean rinse, guided by phase diagrams.

Develop a transparent oil gel cleansing formulation that self-emulsifies with water, using NIKKOL Decaglyn 1-M and glycerin across A, B, and C phases.

Demonstrates how cleansing cream, an oil-in-water emulsion, lifts makeup as oil droplets break and re-emulsify on rinse, emphasizing oil content and Nikkomulese SE-WR for stability and texture.

Formulate a gel-like cleansing cream with 50% oil for a melting, easy-to-massage texture. Emulsify by mixing B into A, then C and D, with butylene glycol and NIKKOL Nikkomulese SE-WR.

Explore how cleansing water and foam cleansers use micellar non-ionic surfactants to adsorb makeup and remove it by rinsing or wiping, with attention to cloud point.

Explore cleansing formulas and performance across balms, oils, foaming cleansers, and micellar solutions, highlighting reversed micelle, D-phase, and bi-continuous structures for makeup removal.
