Sunscreen spray and preparation method thereof

Abstract

The invention discloses a sunscreen spray and a preparation method thereof, and relates to the technical field of cosmetics. The sunscreen spray is prepared from the following components in parts by mass: 30-50 parts of water, 2-6 parts of a humectant, 2-4 parts of a thickening agent, 1-3 parts of a pH regulator, 1-4 parts of an emollient, 2-5 parts of an emulsifier, 1-2 parts of a preservative, 1-2 parts of a fragrance and 5-12 parts of an ultraviolet blocking absorbent, The prepared oil-in-water type sunscreen spray has a uniform and stable system, low viscosity and fresh and cool skin feeling, has the effects of inhibiting and resisting bacteria along with long service life, can provide special fragrance, and achieves the effects of faint scent and skin relieving; and the ultraviolet blocking absorbent can achieve double effects of physical shielding and chemical absorption on ultraviolet rays, and can prevent contact between the ultraviolet chemical absorbent and skin.

Description

technical field

[0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen spray and a preparation method thereof. Background technique

[0002] Appropriate light can promote the body's metabolism and strengthen people's system. At the same time, appropriate ultraviolet radiation can also sterilize and convert deoxysterol in the skin into vitamin D, which is beneficial to the body's absorption of minerals. However, excessive ultraviolet radiation can , will cause damage to the skin of the human body; among them, long-wave ultraviolet rays will accelerate the formation of melanin and skin aging, and medium-wave ultraviolet rays will cause accounting or protein denaturation in epidermal cells, resulting in skin inflammation and redness. With the improvement of living standards and the gradual strengthening of people's awareness of the harm of ultraviolet rays, more and more people begin to use sunscreen cosmetics to prevent the harm of ultra...
