Description

Gel type hypoallergenic cleansing cosmetic and manufacturing method thereof

The present invention relates to a gel-type cleansing cosmetic that has no skin irritation due to low skin irritation, excellent cleaning effect for cosmetics, etc., and a skin protecting effect, and a method for manufacturing the same.

Cleansing cosmetics for removing makeup are classified into cream, emulsion, liquid, and transparent gel types in terms of properties, and are classified into emulsion types, oil-based types, and aqueous types in terms of types.

Representative emulsion types include cleansing lotions and creams, which use 20 to 70% by weight of oily components relative to the total weight to have excellent cleansing effects on makeup and are known to have excellent softness and massage effects when used. However, due to the use of a large amount of oil, this type of emulsion remains on the skin after use and cannot be completely washed off with water, so it must be wiped off with a tissue, which may cause skin irritation due to physical stimulation, and even after wiping with a tissue Due to the remaining oily feeling, it is inconvenient to perform water-based face washing using foam cleansing or soap.

In addition, the aqueous type cleansing gel can be divided into a microemulsion gel type using a large amount of nonionic surfactant and a large amount of oil, and a cleansing gel type using an anionic surfactant. It is mixed relatively more than the above. The former contains a large amount of oil and surfactant, so it has excellent cleansing power, but it has a stiff feeling when used, and it is difficult to wash off completely with water because the oil remains on the skin after use. The latter uses anionic surfactants without using oil, so it can be easily washed off with water and is refreshing when used, but the cleansing effect of removing makeup is poor and skin irritation is a concern due to anionic surfactants.

Oil type cleansing oil uses almost 100% oil, so the makeup cleansing effect is very good and the washability is also very good. However, since oil with low viscosity is used, it is inconvenient to flow down during use and difficult to use with wet hands.
