Cosmetic preparations for facial care, e.g. to soften dry, parched lips are made of natural and synthetic waxes, fats, fatty alcohols, vaseline and ceresin. Their melting point is in the range of 40 C to 50 C. The most important starting materials for the manufacture of lipsticks are various natural and synthetic waxes, fats, fatty alcohols, vaselines, paraffin waxes and dyes. Mechanical strength of the lip balm is achieved by using waxes and microcrystalline paraffin waxes with higher melting points.
Among petroleum products, high-melting microcrystalline paraffin waxes raise the strength and softening point of the lipstick, but are rarely used in amounts exceeding 15 wt%, because they tarnish the gloss of the surface. The melting point of LipCrush varies between 45 C and 65 C. Lower melting types
spread better, while contours are easier to draw with the higher melting lipstick
